I have an HP LCD 19 inch wide screen monitor which came with HP desktop. I'm using DVD-to-VGA adapter and VGA cable to connect the monitor to the Nvidia graphic card.Some games does change the refresh rate of my monitor. Each time when I run or exit some game which will change my refresh rate, my monitor go blank. I have to turn off my monitor and turn it on again to see the screen.Why this problem occurred?Is there any solution?Don't summarize your answer. Give as much details as possible.
The screen only has so many refresh rates it supports, if it's going black it's likely you have hit one that it doesn't support. When it does this you can try either power cycling the display or unplugging it and plugging it back up. This may cause your video to reset to it's default rate and solve your problem until the next time it gets reset. You can figure out what rates your computer thinks are supported by your display by going into the Display properties window, to the setings tab and hitting advanced. Then hit the Monitor tab and the down arrow on the screen refresh rate should show you all that are available. This also gives you the Monitor type at the top, make sure it has the right monitor selected, sometimes you can end up with the wrong one and get strange results, unlikely since it came with it but check it anyway. One other thing,, the problem could be the video card and not the monitor. You might check the specs on both and see if they can handle 70hz, which is likely the problem rate.
It's becasue they arn't designed to go any higher. Only recently have refresh rates gone up to 120Hz on the extremely expensive top end LCD TV's. Going above 75Hz is hard to tell the diffrence, above 120 would be nye' on impossible.
