XG270HU 144hz problem. HELP!

New monitor.

Plugged in with the DP cable that was in the box. I only get 60 and 75hz in windows settings.

I tried everything, using the dvi-d cable, unplugged the other 2 monitors, used older amd drivers, used cru(when i tried higher refresh hz i got no input message in the osd), used custom resolution from an older amd driver(got your monitor does not support this setting message), clean unistall the drivers and new drivers again, unplugged the cables 4 5 times each (dvi and dp) , used defferent ports for the cables. I dont know you name it, i have opened every google page i could fine with no luck.

Also highest reported refresh rate in amd settings is 75hz for all my monitors (2 1080p 60hz, 1 1440p 144hz)

I will call Acer tomorrow but i doubt they will find a solution, propably i will rma the monitor but before i have to make sure its a faulty one, so if any1 has any ideas please for the love of god help me.

The monitor supports Nvidia G-sync at a max resolution of 2560x1440 @144Hz. In order to get this resolution you must use an Nvidia video card that will support that resolution as well. Using a different brand video card may not result in the resolution you need.

I'm pretty sure the XG270HU is a free sync monitor.....not that it matters. Smiley Wink

More than likely you set it up wrong. You should have unplugged your other monitors before you tried to set it up. There should be an AMD control panel that will allow you to setup the triple properly and fix the problem. I don't have an AMD card, but someone in the AMD forum should be able to help you set up the triple.

On a side note, you can't use duplicate/clone and have 144 Hz since your other monitors don't support 144. You must set the XG270HU as a primary display and the use "Extend" if you want 144.

You can also search this forum for discussions about XG270HU firmware....although I'm pretty sure that's unrelated to your problem.

Again, you'll probably need to do the initial setup of the triple displays in your AMD graphics card control panel (not the Windows control panel). Check AMD forum for proper procedure. And then use "extend" to get/keep 144 Hz.
