Custom Resolution Utility (CRU)

I run my monitor at 1280x960@119Hz (120Hz sets something just slightly over my monitor's limit and it won't work), and Windows can see and use this resolution and refresh rate just fine. Games however don't seem to see the refresh rate, and default to either 1280x960@75Hz (desktop res @ max stock refresh rate) or 2048x1536@60Hz (max res/refresh rate stock).

Here's what CRU looks like (only one monitor; no ghost displays in Device Manager):

I recall my 119Hz refresh rate working fine in games in the past. I used a different driver though, "slightly" different GPU (instead of the Twin Frozr MSI GPU I have now, I had a Power Edition; both were still a Radeon HD 7850 though), and used Windows 8.1.

The driver reboot thing didn't work also (games still didn't use 119Hz). Windows reverted to 1280x960@85Hz though, but I could still select and use 119Hz.

2048x1536 @ 60Hz and 1280x960 @ 85 Hz should not exist if they're not listed in CRU. Try disabling the extension block.

1280x960 @ 75 Hz will automatically be added by the driver as a scaled resolution because a higher resolution exists at 75 Hz. Try disabling 1280x1024 @ 75 Hz under established resolutions. Make sure GPU scaling is not enabled in CCC.

You also don't need 1280x960 @ 119 Hz under standard resolutions if it's already added as a detailed resolution.

There shouldn't be any issues with games using refresh rates if you can select them on the desktop.

Passive DVI-VGA adapters don't use DVI signals. They are simply physical adapters that pass the analog signal through without conversion. The 7850 supports up to 400 MHz pixel clock with VGA.
