Custom Resolution Utility (CRU)

[i4ix]

Hi all! Need help with overclock my Samsung monitor.

I have the monitor Samsung 4K UHD Curved EU40JU6790U connected trought HDMI v1.4 on Gigabyte GeForce GTX 950 2Gb OC, and it works with 60Hz perfectly, but I want to configure another resolution for a gaming mode...

I want to run 1600x900 on 85Hz, 99Hz, or maybe 100Hz or 120Hz in best variant...

First, I download and run nvlddmkm-patcher-1.4.0 for NVIDIA, CRU program and MonInfo program (Monitor Asset Manager by EnTech Taiwan), the dump of MonInfo is attached.

Main strings from dump:

Quote:Timing characteristics
Horizontal scan range.... 15-135kHz
Vertical scan range...... 24-75Hz
Video bandwidth.......... 600MHz
CVT standard............. Not supported
GTF standard............. Not supported
Additional descriptors... None
Preferred timing......... Yes
Native/preferred timing.. 3840x2160p at 60Hz (16:9)
Modeline............... "3840x2160" 594,000 3840 4016 4104 4400 2160 2168 2178 2250 +hsync +vsync
Detailed timing #1....... 1920x1080p at 60Hz (16:9)
Modeline............... "1920x1080" 148,500 1920 2008 2052 2200 1080 1084 1089 1125 +hsync +vsync

Now I can run 1600x900 only on 78Hz... if I set 79Hz and more - I see only black screen and no signal info.

Please if anybody knows - tell me how can I tune my monitor for refresh rate 85Hz or maybe more - 90Hz, 100Hz, 110Hz, 120Hz for 1600x900 resolution... Is it possible?

And what I need to do that?

Big thanks to anyone!
