this is the official thread of the
Acer Nitro XV273K,
4K, GSYNC compatible, HDR400, 120Hz (144Hz OC).
I open this thread just to share my impression on the monitor and listen your opinion.
Many users are creating false advertisement on the monitors with I don't know what limitations but I will try to clarify some points.
This monitor can't do 144Hz without big compromise, at 144Hz you have to disable freesync/gsync and you loose the HDR option.
But who cares about 144Hz if you can have all the features at a whopping 4K 120Hz at this price?
I have found that with the 2 display port bundled with the monitor with a RTX2080Ti, windows 10 latest nvidia drivers 441.41,
at 4K, 120Hz, I can have both GSYNC and HDR enabled.
How to achieve this?
Enable GSYNC in nvidia control panel, than enable HDR in windows, than enable HDR mode in Acer Display Widget and you're set.
I can see wonderful color in game while having perfectly functioning variable refresh rate as the internal refresh rate num counter on the monitor shows.
By doing this windows shows sRGB 8bit + dithering but I see no artifact and no particular color loss.
The chrome subsampling test here:
is passed without problems.
Now I'm completely satisfied by this monitor.
Differently from most people say, having HDR enabled in games, is really important because it preserve colors to be too oversaturated.
If I can do it, why so many people complain about the fact that you can't have both HDR and GSYNC enabled at the same time?
I had a lot of monitors before this, but this one is by far the best one I had, it's amazing on every aspects.
Just for info, the monitor has LFC (Low Framerate Compensation) so the variable refresh rate works flawlessly even outside the freesync range.
At 40FPS for example, the monitor goes at 80Hz and the same frame is shown to times, so no problem even here.
PS: I have an Xrite i1 Display Pro colorimeter and I can confirm that the factory calibration is really really precise with a white point near to 6500K and a ▲E < 1. I love the full DDC/CI support of the monitor, the colorimeter sets the RGB gain, brightness and contrast setting directly on the monitor without the user interaction.
