Running refresh higher than supported

[Johnbear007]

Ok, I know that it is bad to run a monitor using a higher refresh rate than supported, but what exactly does it harm?

When you do it, is the monitor actually running at that refresh rate?


I have a 3 year service plan from bestbuy so I don't care if it ruins it. If I don't care about hurting the monitor, is there any reason not to do it?

thanks a bunch

im not 100% positive but it will stress the guns that fire the image on the screen. they may end up burning out. but dont quote me on that... this is more of a bump to your post! sorry cant help more

Wont Damage it, but it wont work either.

Most modern monitors have a protection circuit that puts them in energy save mode if either of the sync signals are out of the monitors recommended range.

If you get a unit that does not do this, yoke heating can occur and ultimately reduce (so some degree) the life of the unit. As long as you stay within the manufacturer recommendations the unit should last at least as long as the warranty period. Some manufacturers offer 5-year warranties.

Another problem is the video amp may not have the bandwidth to provide a image that produces the blackest blacks and the whitest whites. For example: Black characters would look gray. This will not damage the video amp, just make text harder to read since the contrast ratio would be reduced and lead to eyestrain. Thus running faster refresh rates is not always the best thing to do.

Hmmm.

well I have this sony hmd a240r. Its max refresh is 85 hz at 1024x768 but I can bump it up all the way to 200, and it doesnt look like the picture is degraded at all.

So what is going on.. how is it not working (I am really curious here)

I could care less if it kills the monitor in 3 weeks really. I can just go get another from bestbuy for free.
