Refresh rate locks to 48hz, when FPS is higher than 144 while Freesync is turned on

[duythien097]

I have an Acer XF240h 144hz freesync monitor and I recently noticed a weird issue in games where I have more than 144 FPS. When I have freesync turned on and my fps is higher than 144, my monitor locks the refresh rate to 48hz. For some reason that doesnt happen when I turn off Freesync. Is there a way to leave the refresh rate at 144hz with Freesync on, when my fps go over 144?

I assume you have a AMD graphics cards right?

Yes, a RX 480

if you are using a dvi cable, freesync doesn't support that, i recommend you use a displayport cable or a HDMI cable

hmm, that's strange, double checked that freesync has been turned on in your gpu aswell as on your monitor?

Freesync is turned on in both, the problem is just that when I for example reach 200 fps in CS:GO, my monitor automatically goes to 48hz. It works fine when I cap the fps ingame to 144 but that causes input lag. I basically just want to stay at 144hz with Freesync enabled when my FPS goes over 144

EDIT: And now my monitor keeps changing refresh rate on the desktop and my monitor's on screen display keeps changing between "Mode:Normal" and "Mode:Free sync", while Freesync is turned on

FreeSync adjusts a monitor’s refresh rate over a Display Port link.​ To quote AMD, it allows the graphics card to synchronize the refresh rate of a monitor 1:1 with the framerate of an AMD Radeon GPU. Now I assume the technology cannot increase the monitor refresh Hz. So it must reduce the GPU frame rate(FPS).
I suspect the monitor is in distress since when FS works as advertized, it should reduce the FPS to the monitor refresh of 144 Hz.

Would getting a new DP cable help in any way?

Apparently not

I think the monitor is retiring from the field of play.

I've only used this monitor for like 7 months though
Are the lifespans of monitors usually this short?

Not at all but dropping refresh seems contrary to Free Sync.I looked around, here is a review that confirms that the problem is with the unit
" ..This monitor is not for the feint of heart. Sometimes the settings resets, and it adjusts itself automatically depending on the video that is playing."

Try VSync.

Men this is happening on me also. I recently bought MSI OPTIX MAG271C with 144hz. I'm playing CSGO and my refresh rates are changing, they said it was normal but in some point, but it back to normal when I'm just browsing or watching. I can't wait to switch to 1070
