Hello all ,
About 2 months ago i upgraded from 60hz Dell VA panel monitor to 144hz Acer Xb240h monitor (Non Gsync).
This monitor was advertised as acer xb240h when i bought it and there was no mention of whether it has gsync or not . I assumed it was gsync as it was sold rest of the world as a gsync monitor . This model is not even mentioned on ACER india website .
The monitor arrived and very quickly came to know that its non gsync version and also had no ulmb . I was hoping now that atleast the 144hz 1ms response would work as its very important for me at competitive counter strike .
The monitor came with display port cable , DVI and vga cable . Out of the box the monitor looked very bright and the colours looked washed out . There were no drivers that came with it . I downloaded the drivers from acer website and managed to install the unsigned drivers . Changed the montior refresh rate to 144hz both in nvidia and display panel .
Now there was hardly any difference between my old dell va panel 60hz to 144hz acer xb240h . I tried messing with monitor OSD menu . The monitor osd shows it as running 143 hz 1920 x 1080 even if i run the game at 1024 x 768 144hz . Half of the monitor OSD doesnt work - auto config , wide setting , clock , focus etc dont work . The text also looks fuzzy compared to my old dell 60hz .
Thinking it was a software issue i tried fresh install of windows 10,8 and 8.1 and it made no difference . Tried both display port cable and DVI cable that came with it .
Testing it on testufo.com shows it as running 144hz but in reality it feels same as 60hz . It feels like there is frame skipping? I can hardly find people with same monitor to see if they are experiencing similar issues as this monitor is hardly sold .
The closest thing I found on the internet is that some of the aoc monitors are suffering from this as well -https://www.reddit.com/r/techsupport/comments/3jlgny/new_monitor_144hz_looks_exactly_like_60hz_not/ .
After 2 months of troubleshooting it seems like its a manfacturing defect or acer faking it as 144hz panel 
.
I cant understand why acer is selling old junk with premium price of a gsync monitor here in India .
I regret not buying BENQ .
Any solution to this ?
