AOC C4008VU8 UHD Monitor Review

Conclusion

Clearly, there is a lot to be said for having a large monitor on your desktop. The gain in screen real estate alone is a huge attraction. With so much area, you can easily open multiple windows, all at a usable size, and engage in some serious multi-tasking. And you’ll never have to hunt for an open application. Yes, you can accomplish the same thing with multiple displays, but once you’ve eliminated those dividing lines it’s hard to go back. We’re talking about almost three feet of uninterrupted width here. And the curvature means you’ll see the entire image clearly with no change in brightness or color. An 1800R radius sounds tight, but in practice it’s just enough to enhance without distortion.

Now that the tests are complete, can we call the AOC C4008VU8 an excellent monitor? Well, yes and no. Visually, it’s almost a home run. The screen looks fantastic with high contrast and rich color that extends perfectly out to the DCI-P3 gamut. While that might be a liability to those needing precise sRGB color, it works well in most applications, providing just enough extra punch without going over the top. But the stand falls short for us. It desperately needs a height adjustment, because the panel sits too far above the desk in its current form. A monitor this tall should almost be touching the surface of most normal workspaces. At least there is a VESA mount so users have another mounting option.

After raving about contrast, we are disappointed at the lack of HDR support. Many people are fixated on the 1000-nit figure touted by many television manufacturers. The fact is that even bright displays like that are often challenged in the black level department, and their true static contrast ratios are closer to 2000:1 or less. That won’t show HDR effectively no matter how high the output is. The C4008VU8 easily delivers over 4000:1. Short of an OLED or plasma panel, dynamic range doesn’t get any wider than that.

We are happy to see such an accurate presentation of the DCI-P3 color gamut though. Many wide-gamut pro screens have a DCI option since it falls within the Adobe RGB space. But few can render it as precisely as this AOC. Left in its Standard picture mode and Warm color temp, it just squeaks onto our list of monitors that don’t require calibration. That’s a good thing since adjustments won’t produce any significant gains.

All our talk about performance pales in comparison to the sheer size of this display. If you have the room for it, there is nothing else that will be as impressive on your desk. Add to that a nicely styled white chassis and you have the potential to add something unique to your system. As I write this review on a 32” BenQ monitor, I wonder if the task would be easier to accomplish on the C4008VU8. Before you run out and buy a cheap television to anchor your system, take a hard look at this jumbo curved beauty from AOC.

    Why not just buy an LG 43" 4K TV for $400.

    PWM?

    I have a 43in Sony Bravia X800D TV I bought for ~$650, I bought it specifically for its size and HDR capability. If this had been out 8 months ago I think I would of bought it instead. The review mentioned not all HDR TVs fully benefit from their HDR, I wonder if mine is in that boat... I do notice a difference with it on but perhaps the effect is not as strong as it could be. I wonder if the picture would be better on this monitor.

    When I saw the title I hoped for a second that the first 4K monitor that is worth the money has arrived. Too bad it isn't it.
  • Zerstorer1
    40" Samsung KU6300 HDR 4K 4:4:4 60 fps gaming for 399. Been using it for year as my personal desktop screen.
  • Zerstorer1
    I've been using a Samsung KU6300 for year now. Got it for 399. Heal of deal. Supports 4:4:4 and HDR 60 fps at 4k gaming.
  • hannibal
    Why so? This monitor is very well worth of its money!
    It is big and picture quality is nice!
    Even 27" 4K monitors cost almost 600-1000$
    And if it is any better... it is even more expensive.

    Hopefully we will get HDR and freesync version below 1500$ sooner than later. That would be bargain!

    I bought a Samsung UN40KU6290 40-inch 4K TV last November from Costco for $289 to use as a monitor for my gaming system. There are usually a lot of trade-offs when using a TV as a monitor, and I agree that using a purpose-built computer monitor should always be better. Still, if you can find a TV that meets your own minimum requirements, you can save a LOT of money.
  • Brian_R170
    Zerstorer1, +1 on the KU6300. Reviews said it's the same as my KU6290 but has a fancy remote. The only thing I miss that a purpose-built computer monitor would have is auto-sensing the inputs to automatically power-on from standby. The KU will automatically go to standby after it senses all inputs are lost for a few minutes, but it doesn't power-on automatically.

    I'm wondering in the warm whites are often a problem with AOC. I returned one couple years because of that, and, you know, it kinda left a bad aftertaste.
  • AnimeMania
    I was hoping you would have included a close-up photo of the connection ports on the back, they look interesting.
  • WINTERLORD
    a 800$ monitor without HDR yea right
  • ahnilated
    I was tempted until I saw "curved". I am so sick of the curved crap.
  • irtehyar
    Please let curved finish dying already. :(
  • photonboy
    RobertGru,
    Why not 4K HDTV? They literally answer that question in the first paragraph.

    I don't think you can select resolutions like 2560x1440 either so it can be problematic for gaming.

    Hi ..Buy a Sony Bravo TV like $3.5k in 2007 ...print this article and then eat it....
    or rewrite it....

    Decent price for such a large 4K 10-bit monitor, but no HDR support and no Freesync is a deal killer. I'd have been willing to pay $200 more for HDR10 and Freesync support. Like many, I have an Xbox One X on pre-order and am in the market for a 4K HDR monitor to take advantage of it. Looking to replace the 32" 1080p desktop HDTV used for my PS4. I do not game in my living room where my 4K HDR10 TV is.
  • hannibal
    4K tv is not a monitor, even you can use it like monitor. There is big difference in there...
  • rwinches
    If you buy a large expensive monitor like this you are going to use a VESA mount that gives wide range of adjustment and stability.
    If there is no 'perfect monitor' then there is no point in the mention.
    Like their excellent 144Hz 1080p 24" monitor at $200 that they followed up with a same spec Freesync monitor for $220-$250 street (both favorably reviewed by Toms) I believe AOC will offer an improved version of this 4K for a reasonable price.
    Wow, what a weak list of cons and no recommendation?
    No gaming impressions? Is it only good for productivity SW?
    No pic of a bunch of apps open on the screen or a full screen spreadsheet or split screen?
  • zodiacfml
    The introduction is quite misleading leading me to think that this goes beyond 60Hz. This is no different from Philips' 40inch and above 4K monitors.

    If you are referring to this opening paragraph comment:

    Quote:
    It’s not too hard to find a 40” or larger Ultra HD TV at the local wholesale club for less than $1000. But going this route can have a few downsides. First off, you won’t find a consumer TV with DisplayPort. And more importantly, most sets won’t accept signals above 60Hz, even if they refresh at a higher rate.


    They are referring to the extremely limited availability of 4K HDTVs <$1K with >60Hz refresh rate capability, and this one is no exception. That's the way I read it initially, but I now see where it can be interpreted that this set does run higher than 60Hz and is an ambiguous statement.
  • Zerstorer1
    Well that is debatable to a degree. My Samsung KU6300 has an option to specify that a PC card is hook up to it. Once it has done that, the 4:4:4 text mode kicks in for super crisp text and also enables full HDR for vivid deep color as well as 60 FPS / refresh at 3840x2160. My 1080 TI runs all my games at 4K at 60 FPS. Now obviously its capped at 60 FPS, but for $400 at a 40" screen with HDR. Plus I get to use 4K Netflix, 4K Hulu, 4k Amazon with multiple additional inputs. Kinda sinks the battle ship of these $1000+ dollar 28"-32" monitors they are hustling in my opinion. Now get this I have been reading that Samsung is bringing free-sync to their TV line up at the end of the year, although that's only good for AMD cards. So might switch to Vega next year and get another $400-500 Samsung that will have access to 144 refresh, plus all the previous mentioned goodies. Just my 2 cents.

    I bought a Sony Bravia 32", 768p HDTV probably about 2007 and it's still going strong. Paid $3,500 (CDN) for the 768p as it was 5K for the 1080p version. Still pretty good picture.

    In fact, it has way better speakers than any HDTV today from what I can see (probably not much proportionate cost to use good speakers when the TV was so expensive).
