Is it dangerous to force unsupported refresh rate ?

Hi
I have the monitor AOC i2353Ph and it only support 60Hz at native resolution 1920x1080 and because I have bad red eye strain I tried to create a higher refresh rate

so I went to nVidia control panel and create a custom refresh rate and after some testing only with 70Hz (progressive) I as able to see a picture 75Hz or above was displaying blank screen.

I want to ask if using that refresh rate is dangerous also I did not change the timing I leave it at auto. I notice also the picture colors now is more sharper at 70Hz than before !!

Your thoughts please

If your monitor only supports 60Hz, selecting anything higher than 60Hz will give you a blank screen.

Not always, some catleaps can hit 120hz... my old samsung could do 70hz for about 20 minutes before conking out.. Due note that changing the refresh rate above what's supported can fry the monitor.

Sometimes controllers can go a little beyond the default common refresh rates of 60 and 120.

You'd really have to test alternative settings on your own. For example my current monitor is rated for 120hz, but the vertical freq extends to 125hz before going out of range @ 126.

I tested that as I siad and 70Hz seems working fine but I am afraid to damage the monitor.

Some monitors can be damaged overtime. Same for forcing unsupported resolution.

Decrease the contrast and brightness of your monitor.

Or use f.lux
