How to real time monitor my screen refresh rate?

[permanahadi]

hi guys
im using LG 22MP68VQ and the OSD doesnt show the refresh rate (HZ).

i need to check if the freesync over HDMI of my monitor is working,
so i want to see if my monitor refresh rate always match with the fps that my graphic card draw.

is there any way to see the real time fluctuation of my screen refresh rate ? (like when we using FPS viewer in FRAPS, but this is more like HZ/refresh rate viewer)

PS: the reason i want to test this is, i still see some screen tearing with freesync enabled on amd catalyst and monitor setting even when i cap the FPS at 73fps (amd catalyst show my monitor has 40 - 75 hz freesync range). i tested it in game CS:GO with fullscreen mode and vsync disabled. i capped the fps using in game console command, because AMD FRTC makes so much input lag :-/

thanks

You can download this Windmill Demo from AMD and see if the Demo is very smooth no matter the frame rate. That's really the only way you can know that Freesync is working. I've done the same with my Nvidia GSYNC and let me tell you, this experience is amazing lol.

hi zeus
thanks for your answer

i've done the windmill demo before and also the UFO test thing. everything went smooth and no tear.

but the problem is im still getting screen tearing in games that i play (CS:GO, DOTA 2, Grim Dawn, etc). so i need some way that more reliable to tell if this is a freesync not working problem or someother problem.
ps: to be honest i've never seen a fail windmill demo test
