Windows 7: 144hz shows in windows, but is not working

07 Jul 2016   #1

Windows 7 Ultimate x64
144hz shows in windows, but is not working

Hello, I have a AOC 2460 monitor running 144hz. I have had for quite some time, just not bothered to fix it before now. It supports 144hz, and it shows in windows, when i right click -> screen resolution -> advanced settings -> monitor. I have 144hz checked, and it looks like it should be working properly, but my screen is clearly not displaying 120hz or 144hz. I have to correct output on my pc (I have two, one supports 144hz, one does not). I also have the correct DVI Cable. I'm not very computer savvy, so any help would be appreciated. Thanks in advance! :)

Edit: Running AMD Radeon HD 6800 gpu, if it matters. I have tried both 120hz and 144hz

Hello imaginecats mate would like to know what the motherboard is if you cannot see it labelled on it see this and use PART B: in it there will be a motherboard section click on it. Now the number of the board is usually in quite a clear title see pic
Using HW Info
You can test the volts on the PSU with HW Info HWiNFO, HWiNFO32/64 - Download < download the right bit version and close the right hand window select Sensors and scroll down to the power section where you will see what the volts are doing see my pic. In my pic the section (Nuvoton) with VBATT as a dead give away you are in the section for the rail voltages. There are other section titles and one that pops up often is ITE (sometimes the usual one for Gigabyte boards)
Now the voltage on the different rails have to be within 5% =+/- of what is required or the machine will not work properly if at all.
Limits +/-
12v = 11.4 12.6v
5v = 4.74 5.25v
3.3v = 3.135 3.465v
The Power good signal voltage at pin 8 on the 24 pin plug (grey cable) should be the same as the 5v rail reading/s
See this for the rail voltage info
PSUs 101: A Detailed Look Into Power Supplies (Section 2.)
The original right hand window shows the machine running and is handy for that but for looking at the components in some detail close it and use the main left hand side panel
Open each small square with + in it on the section the components are in and then click on the individual component/s (it will highlight in blue) - in the right hand side will appear all sorts of details including brands speeds and other essential info that particular device. See pic for example.

Hi and welcome to SevenForums,
How are you connected to the gpu = display port it's supposed to be the only supported method for higher resolutions/ Hz
Does AMD support 144Hz?? - Page 2

Oops also if you have a amd control panel like we do for NVidia see if it's set to use 144Hz
