Force Higher Refresh Rate?

Question

Is there any way to MAKE my monitor work with a refresh rate higher than 100hz, even though it isn't supported?

Answer 1

It depends.

If your monitor has a 100 Hz vertical limit, then no. Exceeding that will either cause a blank screen or cause an early failure.

If the limit is due to the horizontal scan limit being reached, then if you reduce the resolution of the screen then you can increase the vertical refresh, up to whatever the monitor's actual vertical limit is.

But why do this?
If this is for flicker then nobody perceives flicker at 85 Hz. Any higher is not only pointless it makes the screen look worse. As you up the vertical scan rate everything else has to move faster too. So you have a higher horizontal scan rate and a a higher pixel rate. Since the slew rate (the time to change from one level to another) of the video card and the video amplifier i the monitor are fixed as the pixel rate goes up the time per pixel goes down and less and when you subtract the fixed slew time you have less time where the signal is at the correct level. Possibly even zero time. Characters can become blurred, vertical lines become much dimmer than horizontal lines.

The only reason I can possibly think for needing >100Hz refresh is if you are using stereoscopic LCD glasses that blank alternate eyes each frame and so halve the fram rate.


All this is for an CRT.

For an LCD there is even less point as LCDs do not flicker. Too high a vertical refresh rate can actually damage the liquid crystal material.

Answer 2

NO NO NO

forcing your refresh higher than supported by the monitor
will cause a very fast failure of the monitor

the refresh value is a reference to a portion of the scan
in the vertical cycle DO NOT exceed supported limits

Answer 3

go away it at 60hz. The output refresh fee truly does not have any bearing on the overall performance of an liquid crystal exhibit exhibit, and because that's liquid crystal exhibit you're able to save it on the default. those panels refresh individual pixels, no longer the excellent exhibit screen it is what the refresh fee putting on your exhibit properties has to do with. The refresh fee that the adapter is desperate to is defaulted to 60hz so in case you ever connect an older CRT video exhibit, it truly is going to particularly paintings. returned, the refresh fee that the exhibit adapter is desperate to has no longer something to do with the way your liquid crystal exhibit refreshes pixels.
