Just a while ago the first 4K 144 Hz monitors became available with the ASUS PG27UQ and Acer X27. These $2,000 monitors no longer force gamers to pick between high-refresh rate or high resolution, since they support 3840x2160 and refresh rates up to 144 Hz. However, reviews of early-adopters report a noticeable degradation in image quality when these monitors are running at 144 Hz. Surprisingly refresh rates of 120 Hz and below look perfectly sharp.
 
The underlying reason for that is the DisplayPort 1.4 interface, which provides 26 Gbits/s of bandwidth, just enough for full 4K at 120 Hz. So monitor vendors had to get creative to achieve the magic 144 Hz that they were shooting for. The solution comes from old television technology in form of chroma subsampling (YCbCr), which, in the case of these monitors, transmits the grayscale portion of the image at full resolution (3840x2160) and the color information at half the horizontal resolution (1920x2160). - Techpowerup

    Interesting info here.  A bit underhanded if it really wasn't disclosed to consumers up front.

    Early adopters get the early problems.

    120hz versus 144hz really isnt that bog of a jump anyway. May as well stick to 120hz for the perfect resolution to refresh rate mix.

    Personally, I wouldn't care if the specs for these displays were for 120Hz max if that's what I thought I was buying.  But the specs should be accurate so consumers don't feel cheated.
     
    Reminds me of the Nvidia 970 debacle.

    Oh yeah, they should be accuracte, i dont disagree there at all. But this, again, is an early adopter issue. People shouldnt jump on every single piece of new tech right away.

    Maybe they wanted the $2000 price tag because if they had stepped back and were truthful, they'd feel they can't have that rip off price tag anymore.  Who knows....This is ridiculous nonetheless.

    It looks like the 4K 144hertz monitor manufacturers had to become creative at refresh rates above 120hertz. Display port 1.4 supports 120 hertz. That is the max. The solution comes from old television technology in form of chroma subsampling (YCbCr), which, in the case of these monitors, transmits the grayscale portion of the image at full resolution (3840x2160) and the color information at half the horizontal resolution (1920x2160). This is why the image might be slightly blurry at frequencies above 120 hertz. Personally I feel the manufacturers should have just stuck to 120hertz refresh rate.

    I own a predator x27. Blacks don't get crushed in HDR games when using 4:2:2 10-bit color to achieve 144Hz. For SDR games 120Hz 8-bit color is best unless you want to run 98Hz to achieve 10-bit color. HDR also works with 8-bit color, so you could leave it at 120Hz RGB FULL 8-bit for both SDR & HDR games.

    Glad I'm a big believer that 27" is too small for 4k otherwise I might've shelled out the 2k, NOT.

    reminds me of the early 4k monitors, where you had to use either MST to pretend it was two different monitors, then fuse it together, or downgrade the color information to get it to run at 60 hz.
     
    that said, I don't see a problem myself with running at 120hz over 144hz, I'm still using a 60hz UHD monitor and it's quite doable for my uses (not playing any twitch/fast reaction time games)
     
    that said, they could have advertised "120-144 hz*" with the asertisk there, then mention the color downgrade at 144hz.

    I was wondering where the compromise would be to "overclock" to 144Hz since DP1.4 would not be up to the task. 120Hz to 144Hz, we can all do that math.... its a few more frames but does not matter too much like everyone here says. If this is the only "issue" which is a questionable bit of marketing, then I consider the new monitors a success.

    As long as your popular enough, you can get away with anything.

    I feel 120hz is pretty good for gaming and kind of am not auprised to hear about an issue. The good news is it gets better from here on out as the first generation issues are worked out.

    I inputted the bandwidth of the display at 120Hz with 10 bit color depth at 3840x2160 and the calculated result is 35.83Gbps according to http://k.kramerav.com/support/bwcalculator.asp
    If the max bandwidth of DP1.4 is 26 Gbits/s then these settings are above the limits of DP1.4 despite what is being stated, but I clearly see the settings at 4K over DP1.4 being 120Hz from various sources although the color depth isnt specified....  The display would need to have a maximum refresh rate limit of 87Hz to stay within the max bandwidth of DP1.4 if it is 26Gbps/s.  Anyone want to point out where the error is in all this?

    The 1180 better not cost $1500.

    Just a while ago the first 4K 144 Hz monitors became available with the ASUS PG27UQ and Acer X27. These $2,000 monitors no longer force gamers to pick between high-refresh rate or high resolution, since they support 3840x2160 and refresh rates up to 144 Hz. However, reviews of early-adopters report a noticeable degradation in image quality when these monitors are running at 144 Hz. Surprisingly refresh rates of 120 Hz and below look perfectly sharp.
     
    The underlying reason for that is the DisplayPort 1.4 interface, which provides 26 Gbits/s of bandwidth, just enough for full 4K at 120 Hz. So monitor vendors had to get creative to achieve the magic 144 Hz that they were shooting for. The solution comes from old television technology in form of chroma subsampling (YCbCr), which, in the case of these monitors, transmits the grayscale portion of the image at full resolution (3840x2160) and the color information at half the horizontal resolution (1920x2160). - Techpowerup

    I inputted the bandwidth of the display at 120Hz with 10 bit color depth at 3840x2160 and the calculated result is 35.83Gbps according to http://k.kramerav.com/support/bwcalculator.asp
    If the max bandwidth of DP1.4 is 26 Gbits/s then these settings are above the limits of DP1.4 despite what is being stated, but I clearly see the settings at 4K over DP1.4 being 120Hz from various sources although the color depth isnt specified....  The display would need to have a maximum refresh rate limit of 87Hz to stay within the max bandwidth of DP1.4 if it is 26Gbps/s.  Anyone want to point out where the error is in all this?


    HBR3 mode allows 32.4 Gbits/s.


    Ah well then the article for this thread must be stating 8bit color depth for 3840x2160 at 120Hz, because 10 bit color depth goes above 32.4Gbits/s.  I guess when using 10bit color depth for the upcoming 3840x1440 200Hz HDR-Gsync displays, I will have to limit the refresh rate to 160Hz over DP1.4.
