[TFTCentral] Acer Predator XR341CK 34" Curved Gaming Screen with G-sync - Page 463

post #4621 of 6126
Can anyone refer me to troubleshooting my problem.

Currently trying to overclock the monitor to 100hz, but the screen flickers and reverts back to previous setting. Can hit 95hz no problem, but once I try 100hz, it black screens for maybe 7 seconds and fails to apply.

Edit: Also seeing weird black lines that sometimes flickers while playing BF4 for instance. Happens occasionally thinking.gif

Edit 2: Right after closing the browser after posting, my desktop was flickering like mad. Just went from 95 hz to 90 hz and all is stable. I suppose the module simply cannot handle the overclock. Time to return me thinks.

So my issue has been resolved with a fresh install of windows 10 where the registry has no profiles of old monitors.

After I installed the Nvidia driver and rebooted, the Monitor came up as the Acer Predator x34, the profile came up as 100hz and everything works just perfect. smile.gif

Wait shouldn't G-sync cap the refresh at 100Hz confused.gif

Gsync only comes into effect at 30-100fps but doesn't stop the framerate going above. There is a seperate option in the Nvidia control center that you can choose to have on if you want where you can have Vsync enabled if the FPS go over 100. I limit my FPS to 98 so Gysnc is always in effect, as some say Vsync at 100fps could introduce some input lag.

Hey I'm having the same issue.. I just got the acer x34 and could only get it to oc to 95hz, I sent acer a message asking them what's the deal on fb but i"m also going to contact the support and see what's going on..

I had the same same issue having this monitor only being able to oc to 95hz only instead of 100hz.. I'm going to contact acer and find out whats the deal and if I have to I'm going to return it as well.. This is very misleading..

Have you tried running a lower resolution at 100 Hz?

3440x1440@100Hz is very close to the limit of DP1.2 and that could also mean that the video card is at fault at not meeting the spec.

Just recieved my monitor.. packaging had a huge hole on the side wich i could stick my hand through.. thankfully there was nothing wrong or damaged on the monitor.

- Clocks to 100hz with no problem
- no blue banding
- very minor high pitch noise when displaying white on the screen.
- minor blb (most is in low left corner)
- No frameskipping when clocked to 100hz

I did however got the half lit screen when i first turned it on.. but went away when i got into windows. (hoping it can be fixed with an update somewhere down the line).

All in all i think i got lucky... If anyone has any questions feel free to ask. thumb.gif

That high pitched noise was the reason why I had to send my first one back - it was clearly audible from 1M away. Is yours as bad as that?

Also, anyone here who has one that has no coil whine whatsoever on an all white background?

No, mine is barely noticable.. il try and listen more closely tonight since i live next to a busy road and lots of cars are driving by all the time.

I'm wondering if this issue of not getting up to 95Hz is like the problem I had.

I originally had a 144Hz monitor on my computer when I switched over to the Acer and had a heck of a time even getting the monitor to come on in windows. In the end I had to hook up the HDMI cable for the monitor to be viewed in Windows and then with changing the input back to DP I was finally able to get it to where I wanted, but I noticed there was a ghost profile in the Nvidia control panel upon a new restart. I would have to change the profile back to the one i wanted after every reboot.

I was thinking that my computer was getting confused with having several monitor profiles, so I reinstalled everything. This resolved everything. I booted up in Window 10 after a fresh reinstall, installed the GPU Drivers and everything was perfect.

So I'd be interested in knowing if removing all the monitors from the registry and restarting might reset everything and allow the monitor to clock properly to 100Hz.

Just curious. The place were I believe the GPUs are at in the registry is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\
