NEED HELP WITH ACER GD245HQ

[hell1h]

Hello everyone, i just got a second monitor and i want to use it for csgo. Its the 120hz Acer GD245HQ, and i have some problems with it. When i play csgo at 120hz i experience frame skipping, like stuttering. This is not happening if i switch to 100hz. Any proffesor here ? Please give some advices...i have no problem with benq xl2411t and its 100% the monitor fault, no driver or hardware related. From other rewies from internet i found a couple of users having the same problem but no one found a solution. I use the dl dvid cable. Thanks and sorry for bad english

no one ?

it seems like when i switch to 120hz, the monitor is getting frame skipping, like it couldnt render at 120hz all the frames...

is this forum dead? :/

i just discovered something... when i create a custom resolution with custom timmings (CVT or CVT reduced blank) at the same 120hz, everything untouched, the problem is gone. can some expert help me ?

Are you running in lightboost mode? BTW please don't crosspost this to the benq blur reduction forum, there's less traffic there anyway and that's considered spamming.

is this like the screen (monitor only, not the computer) 'freezing' for exactly one frame, every 1/3 or 1/2 of a second, with the image literally frozen at that spot, even if you are constantly moving? And on the windows desktop itself, Does this cause the mouse to apparently 'freeze (even though it actually keeps moving) every 1/3 of a second, at the spot it was at, then it suddenly acts like nothing happened and keeps moving?

If so, I can replicate this in a way by using an 'unsupported' lightboost mode of 125hz with a 1155 vertical total on the VG248QE, and 121hz with 155 VT on the 2720Z (the Z's backlight pulses rapidly also (bizarre) while the VG's strobe backligiht remains steady).

If you use 125hz with a 1143 Vertical total instead of 1155, the 'hitching' seems to occur TEN times a second instead of 3 times a second.
(again this is lightboost mode).

If you are NOT using lightboost mode, then get a different monitor. If you read those forum threads that you linked, you would see that there's a problem with 120hz on this monitor with the default videocard settings. Using custom timings gives you different horizontal or vertical totals, which probably bypasses whatever is making the screen spaz out. so just make your own 120hz resolution or get a Vg248 or a Benq 2420Z or 2430T screen

no i`m not running any lightboost utility. Actually, i did that, my own 120hz resolution, but its kinda different and i feel my mouse moving different ingame (cs:go)

Try changing the "prerender limit" to 2 or 1 in the Nvidia control panel (max frames rendered ahead), as CS:Go is a DX9 game; dx10/11 games seem to ignore this setting.

its not the "prerender-frame" thing. the monitor is skipping frames at default timings on 120hz resolutions
