Epson Residence Cinema 5050UB evaluation: Excellent projector for severe house theaters



The Epson Residence Cinema 5050UB is a severe house theater projector for severe house theater fanatics. It incorporates a motorized lens with horizontal and vertical lens shift, plus ample zoom. Its 4K enhancement expertise provides plenty of element. Its largest profit over cheaper 4K projectors, nevertheless, is a superb distinction ratio for deep, darkish shadows and vibrant, popping highlights.


  • Excellent total image high quality
  • Glorious distinction ratio
  • Motorized lens
  • Ample lens shift and motorized zoom

There are only some disappointments, and so they’re minor. It does not fairly have the colour or razor-sharp element of its direct competitor, the LG HU810P. That is to not say the 5050 is not sharp and colourful. It’s, only a bit much less so — though I appreciated the Epson’s total image high quality much more than that of the LG. The 5050UB can also be an absolute unit, a number of occasions bigger than any of the projectors I’ve reviewed within the final 12 months (together with the LG).

In sum, the Residence Cinema 5050UB is a superb all-around projector that appears implausible with all content material. It provides a major step up in image high quality over cheaper projectors, just like the Optoma UHD35, whereas providing anybody with a devoted house theater a projector worthy of the area.

Specs 4(Ok) days

  • Native decision: 4K enhancement (1920×1080 x2)
  • HDR-compatible: Sure
  • 4K-compatible: Sure
  • 3D-compatible: Sure
  • Lumens spec: 2,600
  • Zoom: Motorized (2.1x)
  • Lens shift: Motorized H/V
  • Lamp life (Medium mode): 4,000 hours

The 5050UB is a 4K- and HDR-compatible projector. As such, it could actually settle for 4K and HDR indicators, although remember that no projector can do HDR very well

Like all Epson projectors the 5050UB makes use of an LCD light engine, not the DLP that is present in most different projectors. Those used on the 5050UB aren’t technically 4K native decision. As a substitute, they seem to be a expertise known as “4K enhancement” that “shifts every pixel diagonally to double Full HD decision,” in line with Epson. That is accomplished in a short time, so it is only a higher-resolution picture to the attention. This is a deeper dive into the technology. The brief model: It seemed lots sharp to me, if not fairly as razor-like because the DLP-powered LG; see beneath for particulars.

One of many 5050’s most notable options that units it other than cheaper projectors is a motorized lens. This provides ±96.3% vertical and ±47.1% horizontal motion, which ought to be sufficient to let the 5050 slot in nearly any house. There’s additionally a major motorized zoom of two.1x.

Six things to know about home theater projectors


Epson claims the 5050UB can produce 2,600 lumens. I actually measured slightly more than that… in the less accurate Dynamic color mode. In the more accurate Bright Cinema mode I measured roughly 192 nits, or about 1,732 lumens. This puts it among the brightest projectors we’ve ever measured. 

Lamp life is on the low side. Even in the Eco mode, Epson rates it at up to 5,000 hours. Some projectors of similar brightness we’ve reviewed in the last year were capable of upward of 15,000 hours in their most lamp-conserving modes. That said, 5,000 hours is still over three years of use at four hours a night.

  • HDMI inputs: two HDMI 2.0
  • PC input: Analog RGB
  • USB ports: two
  • Audio input and output: No
  • Digital audio output: No
  • Internet: LAN
  • 12v trigger: Yes
  • RS-232 remote port: Yes
  • Remote: Backlit

Both HDMI inputs are HDMI 2.0 and can accept up to 4K60. As you might expect from its intended use as a projector for a dedicated theater, it lacks an audio out. Epson assumes, rightly in my opinion, that anyone getting a 5050 would have a traditional projector arrangement with either a receiver or at least a soundbar for audio.

Along the same lines, there are lots of control options for home automation systems, including a 12v trigger, RS-232 and a LAN port.

The remote is a big boy (just like the projector it controls) and has a pleasant amber backlight. If you have a 2.35:1 screen, as I do, you might reach for this remote for more than just on and off, since you can zoom the projector and fill the screen with 2.35:1 content without getting off the couch. That’s always a bonus.

Picture quality comparisons


The LG HU810P is the most notable competition for the 5050. They’re the same price but the HU810P uses newer technology, namely two lasers and a phosphor instead of the 5050’s more traditional lamp. I connected both using a Monoprice 1×4 distribution amplifier, and viewed them side-by-side on a 12-foot-wide 1.0-gain screen.

Right off the bat, both are great projectors, but their strengths and weaknesses are almost polar opposites.

As far as light output goes, they’re very similar. In their respective most accurate modes, the LG can do 166.3 nits to the Epson’s 192. Objectively, that’s a fair bit of difference, but subjectively, side-by-side, they both just look bright. So we’ll call that more or less a tie.

Color, though, goes to the LG. The lasers, with help from a phosphor, are absolutely deeper and richer. Throw on some HDR content and the deep crimson reds and vibrant purples are far beyond what the 5050UB can produce. This is sort of like saying a Porsche is slower than a Ferrari, however, since the 5050UB is no slouch in the color department. On its own it looks great, the LG in this regard looks better. 


Geoffrey Morrison/CNET

It’s a similar story with detail. The LG uses a 4K DLP chip to create an image, and detail is that technology’s main strength compared to LCD with pixel shifting, which is what Epson uses. The image just looks a little sharper, especially with motion. However, if you’re not watching them side by side, I’m not sure you’d notice. The 5050UB certainly doesn’t look soft, it’s definitely 4K to my eye. 

The next aspect of picture quality is where the tide turns toward the Epson by a lot. In a word, or technically two: contrast ratio. Even without using its iris, the native contrast of the 5050UB’s three LCD chips is significantly higher than the LG — 10 times higher. So the image has significantly more punch and is less washed out. Even if you dial the LG’s lasers and iris back as much as possible, it only just matches the Epson’s black level while that projector is in its brightest and most color temperature-accurate mode. 

Which is to say, the Epson’s black levels are roughly the same while at the same time (in the same mode) it is capable of having highlights or bright parts of the same image that are seven times brighter than when the LG’s lasers are dialed all the way down and the iris is closed. Flipping that around, if you match their light outputs, the Epson’s black levels in the same mode are nine times darker. 


Geoffrey Morrison/CNET

What does this look like? An easy example is watching any movie with letterbox bars. If I set the projectors to be roughly the same brightness overall, the letterbox bars on the LG are gray. If I match their letterbox bars by reducing the LG’s laser power and closing its iris, it ends up looking dim compared to the Epson.

So when watching any content, the deep blacks of the 5050UB, while maintaining bright highlights, make for an extremely pleasing image. 

Charge your friends admission

The Home Cinema 5050UB is an excellent projector. At $3,000 it’s certainly not cheap, but for those looking to buy a PJ for a dedicated home theater or a light-controlled living room that can do its black levels justice, the image quality is definitely a step above less expensive projectors. Is it, say, over twice as good as the $1,300 Optoma UHD35? Perhaps. The Optoma is very good for the price, but that’s certainly the caveat: “for the price.” It holds its own, but it has a way worse contrast ratio and doesn’t handle HDR nearly as well as the Epson. 

I think most people would be perfectly content with the UHD35. But for enthusiasts looking for a more “home cinema” experience the… oh wait, I just said the name of the thing in the thing. Let me try that again. For those looking for a more “home theater” experience, the Epson Home Cinema 5050UB does just about everything right and looks fantastic.

Measurement Notes

I found the Bright Cinema color mode offered the best combination of light output and accuracy. In the six-color temperature mode, the 5050UB was pretty spot on D65 across the grayscale range. In addition, all primary and secondary colors were spot on their Rec. 709 targets. This is one of the most accurate projectors we’ve reviewed in the last year. 

The native contrast ratio was excellent for a projector, with an average of 5,203:1 across various modes. For comparison, the second best contrast ratio we’ve measured recently was the BenQ HT2050A with a native contrast ratio of 2,094:1.

With the lamp mode (called Power Consumption) set to High and the iris off, the 5050UB puts out an impressive 192.3 nits, or roughly 1,732 lumens. The Eco mode drops the light output by about 30%. If you turn on the iris, which opens with bright images and closes with dark images, the dynamic contrast ratio rockets up beyond 100,000:1.

While the Bright Cinema mode looked better overall, the Cinema mode offered wider colors for HDR content. However, it was also much dimmer. I didn’t find the ~10% greater color gamut for ~60% less light to be a worthy trade-off, but feel free to check it out. The contrast ratio was about 40% better in this mode as well, which was only slightly noticeable. 

If you need even more light, the Dynamic color mode puts out an impressive 323.6 nits, roughly 2,914 lumens, though the overall image isn’t as good or accurate.

How a pretend CIA-led vaccine sting in opposition to Osama Bin Laden might nonetheless backfire at this time




A person receives a dose of a COVID-19 vaccine at a vaccination heart in Karachi, Pakistan, on Could 5.

For essentially the most up-to-date information and details about the coronavirus pandemic, go to the WHO website.

Because the world turns a hopeful eye towards coronavirus herd immunity, public well being officers in every single place face the challenge of swaying folks to get a COVID-19 vaccine. 

The hesitancy can stem from political, ethical or spiritual views; concern over vaccine security or worry of unwanted effects; inconvenience; or a fundamental ignorance. In Pakistan, nevertheless, issues may very well be additional sophisticated by a tangled legacy of vaccine mistrust following reviews of a 2011 CIA-led vaccination marketing campaign ruse designed to find al-Qaida chief Osama Bin Laden. 

Shortly after a US army particular operations unit killed Bin Laden on Could 2, 2011, a Guardian article reported the CIA had organized a pretend vaccination marketing campaign within the city the place it believed Bin Laden was hiding. The objective was to acquire DNA samples from youngsters who have been doubtless intently associated to the fugitive chief, below the guise of administering hepatitis B vaccines. 

Revelations of the scheme precipitated an uproar, with extremists launching an intense propaganda effort in opposition to vaccines. And the marketing campaign labored, in line with a new study that appears in the Journal of the European Economic Association. It finds a big decline within the vaccination price within the nation adopted.   

The research does not straight correlate the Central Intelligence Company’s vaccine ruse and present charges of COVID-19 vaccine adoption in Pakistan. Moderately, it makes use of the dramatic occasions of a decade in the past to discover how false data discrediting vaccines impacts immunization charges and different types of health-seeking habits. The findings appear significantly related given how essential public acceptance of COVID-19 vaccines is to halting the pandemic.

“We have been interested by how anti-vaccine rumors and conspiracy theories are typically fueled by true items of knowledge,” mentioned Monica Martinez-Bravo of Spain’s Middle for Financial and Monetary Research, and one of many authors of the paper. “The CIA vaccine ruse gave the impression to be one such occasion.”

The CIA did not instantly reply to a request for remark, however in 2013, then-CIA Director John Brennan issued an order forbidding the use of vaccination programs in its operations.

Martinez-Bravo mentioned the group could not discover one other occasion the place well being companies have been used to cowl up espionage actions. However the research does cite different instances of medical malpractice that seem to have eroded belief within the medical sector, just like the high-profile Tuskegee experiment. In it, public well being employees within the US denied medical therapy to Black males affected by syphilis so they may examine the consequences of the illness. Later, Black males residing near Tuskegee in Alabama developed decrease ranges of demand for formal medication. 

After the Guardian article got here out, Pakistani physician Shakil Afridi was sentenced to 33 years in jail for treason for colluding with Individuals on the scheme. And members of the Taliban accused well being employees of being CIA brokers, claimed polio vaccine campaigns have been a conspiracy to sterilize the Muslim inhabitants and even unleashed violence on well being care employees administering vaccines. One Pakistani Taliban commander banned polio vaccinations in an space of the tribal belt days earlier than 161,000 youngsters have been scheduled to be inoculated.

Following the Taliban’s marketing campaign, the researchers concerned within the new research estimate that the vaccination price declined between 23% and 39% in Pakistani districts with increased ranges of electoral assist for an alliance of events espousing political extremism. They used knowledge from the Pakistan Social and Dwelling Requirements Measurement on youngsters born between January 2010 and July 2012. The data indicated whether or not new child infants had obtained vaccines for diphtheria, tetanus and pertussis (DTP), polio and measles.

“Our findings spotlight the significance of safeguarding belief in well being methods, significantly in contexts with some underlying stage of skepticism in formal medication,” the research says. “Occasions that solid doubt on the integrity of well being employees or vaccines can have extreme penalties for the acceptance of well being merchandise similar to vaccines, which can be characterised by having giant constructive externalities.” 

A remaining query, the researchers say, is that if and the way the general public’s belief might be regained. 

The World Well being Group in 2019 recognized vaccine hesitancy as one of many top 10 global health threats. “Vaccination is without doubt one of the most cost-effective methods of avoiding illness,” the WHO wrote on the time. “It at present prevents 2-3 million deaths a 12 months, and an extra 1.5 million may very well be averted if international protection of vaccinations improved.” 

Whereas the findings have implications past Pakistan, they may assist inform public well being officers within the South Asia nation, the place vaccines have thus far been restricted to well being care employees and folks over 50. 

Surveys show normal vaccine hesitancy is rising in Pakistan. The nation has vaccinated simply 0.8% of its whole inhabitants in opposition to COVID-19. The share of vaccinations per 100 folks additionally stands at simply 1.53%, in contrast with the worldwide common of 16.44%, according to German news agency DW

“Some research counsel the diploma of confidence within the vaccines in opposition to COVID-19 in Pakistan is low — 30% of the inhabitants signifies that they might not get the vaccine,” Martinez-Bravo says. 

In response to Johns Hopkins College’s coronavirus useful resource heart, Pakistan has recorded greater than 864,000 COVID-19 instances, with over 19,100 deaths. In response to United Nations knowledge, the nation has a inhabitants of greater than 224.5 million.

Rocket Lab races to meet up with SpaceX by going rocket fishing




A Rocket Lab Electron rocket awaits liftoff in New Zealand.

Rocket Lab

Within the house launch enterprise, Elon Musk and SpaceX seize many of the headlines, however plucky New Zealand-American outfit Rocket Lab and its affable CEO Peter Beck are making up floor fast. This weekend the corporate will try and get better one in all its orbital rockets after delivering a payload to orbit for the second time in its newest mission referred to as Running Out of Toes.

SpaceX has established a bonus for itself by perfecting rocket recycling, and earlier this 12 months, Beck confirmed his firm would pivot to start reusing its boosters as nicely.

Final November, a mission dubbed Return to Sender noticed Rocket Lab carry out a smooth splashdown touchdown of one in all its Electron rockets within the Pacific Ocean. It was a tentative first step in growing a brand new restoration course of that may finally see the corporate’s rockets blast to house, then start a high-drama return to Earth involving each parachutes and a helicopter that snatches the spent booster from the sky for recycling.

However for now, Beck says the plan is simply to get the moist restoration proper earlier than getting any additional plane concerned.

“There isn’t any level in bringing in a helicopter till we’re actually completely happy with the situation of the stage,” the Kiwi instructed reporters on a Zoom name Tuesday.

When the Rocket Lab group went to drag the Electron first stage from the Pacific Ocean after the Return to Sender mission, the hassle was difficult by 16-foot (5 meter) swells, and the booster suffered some harm within the course of. This time Rocket Lab is utilizing one thing referred to as ORCA (for Ocean Restoration and Seize Equipment), which is a hydraulic cradle on the restoration ship to assist issues go just a little extra easily when the group hauls that very large fish on board.

Beck instructed the media that the corporate did handle to reap a number of the elements from Return to Sender. The propellant pressurization system that flew on that mission will likely be used for Working Out of Toes this weekend.

Along with training the moist restoration, Rocket Lab is working to maintain its rockets from overheating on re-entry. The Electron is a a lot smaller rocket than the SpaceX Falcon 9, leaving no room for using a propulsive touchdown system utilizing engine firing to information the booster again to the floor. As an alternative, the Electron depends on utilizing the ambiance to decelerate as a lot as potential, which implies one of many greatest challenges is coping with the acute warmth generated by pushing so forcefully in opposition to all that air.

Beck mentioned a future improve will embrace a brand new decelerator designed to scale back the thermal load of re-entry by an element of 10.

That decelerator ought to be prepared by the point Rocket Lab performs a 3rd splashdown restoration someday later this 12 months. If that goes very well, then the corporate could also be prepared to maneuver on the daring helicopter maneuver, which Beck mentioned is not really all that daring.

“[The helicopter recovery] just isn’t that difficult to do,” he mentioned, explaining that the logistics of coordinating a helicopter and restoration ship with the touchdown represented a far greater problem.

Beck mentioned every thing the corporate learns from its experiments in recycling rockets will inform the event of its next-generation car, Neutron, which is a far bigger booster designed to truly go head-to-head with the likes of Falcon 9 and others.

However first, Rocket Lab must good its fishing approach.

The launch window for Working Out of Toes from the corporate’s New Zealand launch website opens Saturday at 3 a.m. PDT. The mission will likely be streamed stay and we’ll embed the feed right here as soon as it turns into out there.

Comply with CNET’s 2021 Space Calendar to remain updated with all the newest house information this 12 months. You’ll be able to even add it to your personal Google Calendar.

Tesla halts enlargement plans in Shanghai, report says



Tesla China Data

Tesla is pumping the brakes on plans to carry Chinese language-made vehicles to the US.

Tesla/Craig Cole/Roadshow

Tesla’s Chinese language Gigafactory outdoors of Shanghai is buzzing alongside properly, cranking out tons of Mannequin 3s and Mannequin Ys for the Chinese language home market. Tesla had greater plans for the manufacturing unit that concerned exporting Chinese language-made autos to different markets across the globe, however based on a report published Tuesday by Reuters, these plans have modified.

The Shanghai Gigafactory is ready as much as construct upward of half one million autos per yr, however Tesla had been eyeing land close by to extend its capability. Nevertheless, the continued financial tensions between the US and China and their associated tariff increases make these enlargement plans much less enticing.

Nonetheless, it is not as if these derailed enlargement plans imply that Tesla is hurting. Quite the opposite, it is at the moment seeing a gross sales growth on the planet’s largest marketplace for vehicles. It is sufficient of a growth that  Tesla made over $3 billion there from January to March. Chinese language gross sales at the moment account for round 30% of Tesla’s income.

Even when issues quiet down between China and the US, it is not fully clear how profitable a Chinese language-built Model 3 could be in America, primarily as a result of there is not a substantial amount of information to match it with, since we do not get many Chinese language automobile imports right here, with Buick’s Envision being the notable exception.

We would sometimes ask Tesla to touch upon one thing like this, however because it dissolved its PR division, we will not.
