Wondering if any of you have ever experimented with changing monitor timings?
I was keying in new values for timings for my monitor's native resolution at 60 Hz.
There are differences in the output and how "stable" the picture looks.
GTF, DMT, CVT, CVT-RB, CVT-RB v2, CVT-RB v3 will give different results.
In my video player I was checking the sync with the different values entered for 60 Hz with a 24 fps file.
GTF (?/default driver setting) 59.87693 1 frame drop every 20.31 seconds
DMT 59.88374 1 frame drop every 21.50 seconds
CVT did not work
CVT-RB 59.91801 1 frame drop every 30.48 seconds
CVT-RB-2 59.96006 1 frame drop every 1.04 minutes

Use the first link, it's easier and doesn't need you to find a modeline first.
Don't monkey around with this if you have no technical aptitude.
If you do, some advice I would give regarding the Intel driver custom resolutions setting: First, set a backup refresh rate, I would suggest 50 Hz CVT-RB on the basic tab because it will work easily. The reason for this is because later if you accidentally screw something up, you want it to be able to fall back to a working refresh after 15 seconds otherwise you will have to do safe mode (hassle). Second, there is a bug in the control panel in my version of the driver (maybe fixed now, maybe not). If you enter a custom refresh for 60 or whatever and want to change the timing parameters again, it is not enough to just press 'ok' to overwriting. It doesn't overwrite. Change to your 50 Hz or whatever refresh, and on the remove tab, remove the 60 Hz resolution keyed in. Then you can go ahead and enter the numbers again in the advanced tab. It will pick up the new values properly. Deleting all custom resolutions that you keyed in will reset things back to the driver default (usually GTF). Don't bother with CVT or DMT. Just enter CVT-RB or CVT-RB v2 (try this one first). Where is says active for the resolution in the intel custom resolutions, you have to type in the resolution of your display. Scan rate is refresh rate (e.g. 60 Hz). The rest of the labels are the same as the webpage calculator.
