hi all

so I have an ACER KG271B monitor which is HDR ready,yet in the menu option on the screen it is greyed out.
im sure I had it enabled once when I first got the monitor but not sure how lol.

its a 240hz 1080p panel and im using display port on a 1080ti.

any ideas?
cheers
 
If you running W10, make sure Play HDR games and apps under Windows HD Colour is turned on in settings.
For your monitor make sure you have at least DisplayPort ver 1.2 set.
My Samsung monitor will not activate HDR if less then DP 1.2 is set.
 
hi
yes im running windows 10
yes it is set at 1.2 on the monitor

where is the HDR setting you speak of?
I also see in nvidia panel the max bpc I can set is 8 regardless of wether I choose rgb full,limited or 444/422.
 
hi
on the video playback setting it says 'we didn't find any displays set up for HDR'

if I use dxdiag and use the monitor tab and scroll down it says HDR not supported,

it looks like I have to enable it I guess on the monitor but its greyed out.
 
I don't have a windows hd colour settings tab :(

Yep that option is not there so either the monitor does not have true HDR support or it has one of those fake HDR picture settings modes.
 
The manual does not mention anything about HDR support but in the specifications it says.

<li>High Dynamic Range (HDR)</li><li>Navigation Key</li>

So it there a button on the monitor or a option in the menu to turn it on?
 
yes using displayport with good cables,i can run 240hz no problem,i have 3 of these monitors too and all are the same.
oh well thanks for the help guys..

you can see the HDR is greyed out and cannot change it,now I seem to recall I inititally had my center monitor on a hdmi cable,again being able to run 240hz ok on it..i wonder if that's the issue.

Looking at Acer web site for this model, it does say that it supports HDR.
My Samsung has no button to turn on HDR. You just select DP1.2 and Windows 10 detects it automatically.
 
yes I tried that,im at 60hz now on all 3 monitors,i even tried unplugging 2 of them to see if that helped but to no avail.

the monitor driver that peahead linked to is for the kg271 which is only 75hz,i cant seem to find a driver for the kg271b,whether that makes a difference or not I don't know.
 
ok..this is weird

I connected one of the monitors to a good hdmi lead, now the HDR is not greyed out on my monitor.

I also now see a HDR and WCG slider in windows display settings..altho its greyed out maybe because I still have the other 2 monitors connected via DP
 
ok so I unplugged the other 2 monitors using DP and bingo I can get the HDR working..so for some reason they don't work over DP.

altho looking at how washed out this looks now on the desktop..im not sure I like it lol.

Click to expand...

Glad you figured it out but personally i never use HDR for the desktop just for a select few games.
 
thanks :)

the washed out look was cured because dumbass here hadn't turned it to auto in the monitor options...

oh welli cant run it anyways with displayport so back to SDR.

thanks for the help guys.
