Custom Resolution Utility (CRU)

[Christosk88]

I have overclock monitor my monitor is->https://www.lg.com/in/monitors/lg-22M38H# with custom resolution utility and i don't know how to back to default my monitor support only 60hz and no 75hz i don't have display port only hdmi. So my problem is how to go my monitor back to 60hz? Here is my screenshots...

               

At the last choice extension blocks (2slots left)
CEA-861: 4 detailed resolution, 4 data blocks (HDMI) then i click edit The type is CEA-861 Detailed resolutions
1920x1080 @ 60.000 Hz (148.500 Mhz) [+/+]
1920x1080i @ 60.000 HZ (74.25 Mhz) [+/+]
1280x720 @ 60.00 hz (74.25 Mhz) [+/+]
720x480 @ 59.940 hz (27.00 Mhz) [-/-]

Data blocks
TV resolutions
Audio Formats
Speaker Setup
HDMI Support

So i have open cru now at the top left need to untick 75hz and to left as is it 60hz? Established Resolution.

Detailed Resolution need to do something else or change?

Standard Resolutions: Need To delete 75hz , 16:10 and left as is it 16:9? Or i can add standard resolution 1920x1080? or other resolutions

Extensions Block: Need to delete these resolutions?->1920x1080i @ 60.000 HZ (74.25 Mhz) [+/+]
1280x720 @ 60.00 hz (74.25 Mhz) [+/+]
720x480 @ 59.940 hz (27.00 Mhz) [-/-]

And the last step: Data Blocks
I want to delete tv resolutions audio formats and maybe speaker setup.

I tryed to make as is it but no luck i got a black screen to my pc. My monitor is 75hz and i want to go at 60 hz. Which settings must to do?
