Custom Resolution Utility (CRU)

[Dave3d]

Hello.
Total noob at this.
I have a few questions.

I have:
GTX Titan X video card
Monoprice 30 inch G-Pro Slim 2560 x 1600 monitor that they say will oc to 120hz

My old 1680 x 1050 23inch monitor is going out, and I don't want to go back to 60hz, after having played 120hz for 8 years.

So, I have tried:
1. Launch the cru.exe
2. Selected the ** monitor, selected '2560 x1600 @ 59.971hz (268.50mhz) [+/_] and clicked Add (I have deleted all of the entries in standard resolutions (14 slots left) and selected None in Established Resolutions. I added 65hz lcd standard, and 70hz standard lcd.
3. Either restart the computer, or use restart.exe.
4. Right click desktop, go to monitor > advanved, and select the dropdown.

I have gotten 65hz and 70hz to work, but if I go over 70hz (in the Detailed Resolutions), only 60hz and 65hz show (or, if I delete the 65 and 70 hz, only 60hz shows up).

I tried using a custom Standard Resolution and Custom Extension Block, but when I type in 2560, it goes red, and wont let me set 2560 x 1600.


Monoprice says this will do up to 120hz, period.

I really only need to go to 100hz, I am thinking, for gaming, should be fine.
120hz would be excellent, but anything over 120hz I don't notice (I have an Asus 144hz, and it feels the same as my old 120hz).

I don't want to go down in scale, as 16:9 makes me nauseous (hence, not using the asus 144hz monitor).

Any help is really appreciated, as 16:10 and close to 120hz is normal for me, and I cant do 16:9.

Thanks.
Dave

EDIT:
Nevermind.
I was able to do it through the Nvidia control panel, change resolution, create custom res, 100hz, bam.
Reboot, and flip it to 100hz, all good.
Now to check gaming.
