NEC V801 Review: Benchmarking A Massive 80-Inch Monitor

Results: Viewing Angle And Uniformity

Viewing angles are extremely important for a panel this large. In a home theater environment, you’ll likely be sitting 10-12 feet away, which means the angle from the center seat to the sides of the screen is around 32 degrees. We shoot our photos at a 45 degree angle, which, in the case of the V801, correlates to a seven-foot seating distance. That's definitely too close because you’ll see the pixel structure.

If you expand the photo, you can see there are slight color shifts in both the horizontal and vertical offsets. Light falloff is almost imperceptible, which is better than what we’re used to seeing from IPS screens. In normal content the color shift is barely noticeable. This is one of the best LCD panels we’ve ever seen with regards to off-axis image quality. And it’s another reason why the V801 is so well suited to be a home theater screen as well as a presentation monitor. We’re also impressed with how well shadow detail holds up as you move off-center. You can easily enjoy this display with a few friends and no one will fight for the middle seat.

Screen Uniformity: Luminance

To measure screen uniformity, we use zero percent and 100 percent full-field patterns, and sample nine points. In a change from previous reviews, we’re now comparing the results to other monitors we’ve measured. First, we establish a baseline measurement at the center of each screen. Then the surrounding eight points are measured and their values expressed as a percentage of the baseline, either above or below. We average this number. It is important to remember that we only test the review sample each vendor submits. Other examples of the same monitor can measure differently in this metric.

First up is black field uniformity.

This is where a large-format display is at a disadvantage to desktop-sized screens. A monitor of this size is bound to have hotspots. The center of the V801 is just a bit brighter than the surrounding areas. Considering that it’s an edge-lit display, we're still very much impressed.

We're surprised that the Pioneer plasma doesn't exhibit better uniformity in a black field. At least it's dark enough to hide the the hotspots. Only the meter knows the true result.

Here’s the white field measurement.

The V801 is brighter at the center in the white field measurement as well. Again, it’s barely noticeable to the eye given the sheer size of the screen. But its deviation is higher than the desktop monitors we’ve tested. The Pioneer, on the other hand, rockets to the top of the pack.

Screen Uniformity: Color

To measure color uniformity, we display an 80 percent white field and measure the Delta E error of the same nine points. Then we simply subtract the lowest value from the highest to arrive at the result. A smaller number means a display is more uniform. Any value below three means that variation is invisible to the naked eye.

We have yet to measure any monitor that has visible color shift across an 80 percent white field pattern. Both the V801 and the PRO-111FD are under the threshold. Again, this is a very difficult test for such large a panel.

    Yeah, 1920x1080... those pixels are 0.92mm square. That's pretty easy to see with the naked eye; far bigger than a full stop.

    27.5ppi... *shudders*.

    Ummm... 70 square meters is pretty big. That's about half of the average house. I think you'll find it's ~1.76 m² or 19 ft².

    Why would you want an 80" monitor that is only 1080P?

    On the other had I wouldn't mind having that Pioneer "God" TV

    Way to make a home cinema system with an average computer.

    I wouldn't get such a big monitor/hdtv unless it has a higher than 1080p resolution.

    Thank you for buying this excessively massive monitor to save the environment.

    @Someone: Thanks--missed the calculation error during my edit. Should be fixed now.

    For that size I clicked the article in hopes that maybe it was some 8K monitor. Stopped reading after 1080p

    A wee bit pricey. I'll stick to my six 40" monitors

    I've had a Mits 82" DLP since 2011 I paid $1900.00, that is the heart of my media center, so $9400 for just a monitor is a bit much.

    Be careful with current 4k screens, all of them for 2 reasons.

    1) There is no 4K content available from anywhere. The movie studios are pushing to requiring HDCP 2.2 compliant 4k screens before they will release content and all current 4k are not HDCP 2.2 compliant, only HDCP 1.4.

    2) Current HDMI specifications only allow for 4k@30 transport which is sufficient for movies, however the native glass in these devices generally do 4k@60 which means the screens are doing some format conversion. True 4k@60 requires HDMI 2.0 which has only just been released and no chips support yet. So these screens are generally not good for video games either

    Show me the idiot that spends $10k on a 1080p 80" panel. I bet you can see every single pixel with your naked eye from 6 feet.. What a stupid stupid stupid idea.

    LG has a 4K HDTV for $7000 that is 65". Not quite as big but a much better choice. You can also move CLOSER anyway. Of course content is still an issue.

    I'm not sure any of you read the first paragraph:
    Quote:
    This 80-inch LED/LCD screen is a commercial-grade model that can be used for just about anything requiring a large display. You would most likely see the V801 in an airport, for example, functioning as a dynamic message board or showing news feeds, for example. Obviously nobody's going to set this beast up on their desktop.


    This is obviously not meant for personal use. This is not meant to be viewed from up close.

    I love everyone commenting on "You can see EVERY pixel OMG OMG OMG!" yet you've never owned a large display probably.
    I've seen 80 inch TVs in person and these fears are just pathetically sad. I own a 70 inch HDTV as my primary "monitor" and I never go "I NEED 4k!!!!!!"
    Why would I even NEED 4K at the moment? HDMI doesn't support it yet, and there is ZERO 4K content. If for gaming, the gaming rig necessary to power such a thing is WAY too expensive, and new cards will scale better with resolution than past cards.

    People need to stop commenting (mainly people like chumly), when you've never used such a product before.

    My biggest knock is price. If I can get an HDTV for 1/10 the price on some of these black friday/christmas sales, it really makes no sense to get this. I can get that 70-80 inch HDTV for 700-1000 dollars, then pocket the 6k-7k extra and wait for the 4K versions to come out later. Maybe they'll even have OLED 4K by then.
    But that being said, this monitor did compete and beat MOST displays in MANY specs. It's a GREAT monitor. But I just think that if I'm going to invest 8k into a tech, it shouldn't be at the end of its lifestyle. I hope they put this type of effort/quality where it competes/beats many HDTVs out on the market onto their 4K model when it is ready.

    A monitor this big needs to be reviewed also as an "HDTV" where Movies/TV is watched on it and since that was omitted, I think this is pretty much not too useful to most people who would want a display this big.

    I feel like a lot of people commenting didn't read though, and simply posted.

    We haven't owned 1080P TV's that large for the negative reasons we are talking about, my grandpa owns a 65" and it looks fine if you sit way back but anywhere near it very blurred and distorted due to lack of pixel density

    "You would most likely see the V801 in an airport, for example, functioning as a dynamic message board or showing news feeds"

    if my airport is buying $10,000 monitors to show me which gate to go to... I'd rather have a discount on my air fare pls...

    if someone thinks they need a $10,000 monitor to show TEXT on a black background... well, I odn't know what to say

    I love how you go into the cost benefit analysis of the whole 4K vs 1080p and the practicality of it... while ignoring the fact that this thing costs $9,400... that's nearly 10 friggin grand. it's sturdy and built to last... now I'd expect there to be 4K content 5 years down the road from now...
