Custom Resolution Utility (CRU)

[boancatudor]

I have a problem. So the software works and I can overclock my monitor to 70 Hz (can't go higher because a higher Hz won't show up in the monitor tab). The thing is that every time I restart my laptop, I have to open the "restart64.exe" file again so that the 70 Hz apply again. If not, if I go in the monitor tab, the 70 Hz option will be missing. I am using a laptop with a dedicated monitor connected through HDMI (a BenQ GW2255).

Please help me! Thank you!

Hello guys!

ive been having an issue after trying to set my tv to 120 hz native on my dual screen setup. this is to achive my goal of having my pc output a 12 bit color signal with 120hz. the problem is that when ive set everything up and shutdown my tv. my other monitor randomly starts to flash a black screen serveral times at a time. im completly clueless why this is happening and its very frustrating for me. anyone that can help? ive been searching for anwers without any luck.

Use the "LCD standard" timing option to fill in the values. The values themselves don't matter much as long as they aren't too low. The original purpose was to give the electron gun time to move between lines/frames on a CRT monitor. That's not as important with digital monitors, but most still need some time for processing. Standards exist to make sure certain values always work, but that only applies to resolutions the monitor officially supports. When adding custom resolutions, there's no guarantee the monitor will accept the resolution or any particular timing parameters. If the monitor can't handle those resolutions, you can use GPU scaling. With GPU scaling, the timing parameters don't matter since the GPU will scale the resolutions to the native resolution.

went ahead and used "lcd standard" per you recommendation and while the video resolution works fine it kills the audio, no audio is available - but when i delete the custom resultion and revert back to the windows resolution setting, audio returns.

i'm using a nuc i7-8559U, windows 10 pro latest build, hdmi out, oem installed realtek audio drivers, latest intel display audio drivers.

That can only happen if there's a graphics driver bug. What GPU(s) does the laptop have? What version of Windows are you using?

What video card do you have? When you say the monitor flashes a black screen, how long does it do this? Does it stop after a few seconds or does it continue indefinitely?

HDMI audio is transmitted during the blanking periods, so you probably need to increase the blanking. Try using "LCD standard" and put in 1920x1080 @ 30/60 Hz, then switch to "Manual" and click the "Total" radio button to lock in the totals, then change the resolution to 1920x820. Do the same starting with 3840x2160, and change the resolution to 3840x1634.

I added a few modelines in th 59Hz range but they are not visible in the Display Settings. I made a test with 75Hz and it was fine, but with 59.637 all I was presented with was the default 60Hz modeline (the one at the top stack). I also fear that they will be listed rounded to 60Hz unable to know which is which.

Also, is there a more streamlined way to switch modes? Either registry, command line, etc than going to the display settings each time? Maybe checking registry changes with RegShot.

By the way for a smart tv do you recommend not touching the blanking (use LCD standard) ?

Windows lists refresh rates as integers, so 59.637 Hz would be listed as 60 Hz. Windows doesn't have a way to have multiple 60 Hz refresh rates at the same resolution, but you can have different resolutions with a different fractional refresh rate. For example, you can have 1920x1080 @ 60 Hz and 1918x1080 @ 59.637 Hz. Then you can easily switch using a program like HotKey Resolution Changer. The blanking doesn't matter as long as the resolution works.

One of the features I'm thinking about adding eventually is the ability to export an .exe file that switches EDID overrides. Right now, the only way to achieve that is to make a batch file that loads the .reg file you want and then run restart.exe -q.

EDID overrides are stored in the registry here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY\(Display ID)\(Instance ID)\Device Parameters\EDID_OVERRIDE

That would be cool, I guess that can work around the Windows listing issues. I remember using registry changes back in XP to easily switch displays with AHK.
Do you know of any command line or gui based program to find current display refresh rate? Currently I'm using some web tests and retroarch internal options but I don't entirely trust them.

Hi ToastyX, thanks for all of your hardwork!

I have a Benq GW2255 (60hz) using it with a single link DVI-D, managed to overclock it to 87 hz.

Is there a possibility that I could achieve higher refresh rate overclock using a dual link DVI-D?

Also, is there a rule or something when overclocking the monitor's refresh rate? Like should the refresh rate be divisible by 30 or 24 or 4?

Thanks!
