[FIX] Refresh rate forcing

[MarcoRavich]

I had some refreshing rate problems with my office-workstation' secondary monitor (an old ASUS WK222H): the - modded but not using CS - Win10 installation frequently switches between 59,852Hz and 60,164Hz causing temporary monitor drops - black screen - from HDMI.

I found this regfix that would be cool to be implemented somewhere in CS:

EDIT:
...seems that I'm not the only one with such kind of issue...

Here's another interesting regedit script that could be useful:

Clear and Reset External Display Cache

Hope that inspires.

I cannot implement it safely due to this:

I'd rather not risk damaging one's monitor with a 'hacky' PowerShell script, but I'll mention the fix on the wiki.

Added both of the tweaks mentioned here to the Wiki's sidebar, in the Fixes category.

OK, just discovered @radamar's Custom Resolution Utility (CRU) which - even if a bit dated - seems to work well for customizing/setting monitors' refresh rate and resolution under modern Windows.

Bump.

Just found this interesting tool by @Sparronator9999: Refresh Rate Tuner.
