Custom Resolution Utility (CRU)

I just found out this great utility and I would like to ask you about some help as I don't know where to find the solution

Display:
- LG L245WP-BN (official LG drivers installed) connected to my miniPC via HDMI cable

PC:
- Intel NUC (CPU: i5-5250/8GB RAM/GPU: Intel HD Graphics 6000) with 64bit Windows 10 Pro

I was trying to connect this old display to my miniPC but the whole screen is cropped/shifted as can be seen at attached photos.

I was trying to check and overwrite the EDID of the display (EDID dumped via Phoenix EDID Designer) but as far as I know these problems are usually connected to NVIDIA GPUs. Anyway, I checked the EDID of the display in registry (regedit) but the table is very the same as the result from Phoenix EDID so there was nothing to change.

When I launch the CRU, there are also no other extension slots that could be deleted.

Do you have any idea how to solve this problem? I don't want to throw the display in the trash as it is basically OK

Thanks a lot for your help!

You're complicating things with multiple programs. Your CRU screenshot is showing something was changed. Run reset-all.exe and reboot to restore the original EDID. Then use CRU only to delete the extension block for the monitor and reboot again. If that doesn't have any effect, then you might have an older Intel graphics driver that doesn't support EDID overrides. In that case, use the alternative method by using the "Export..." button to export a .exe file. Then run the .exe file, and install the EDID override. Then reboot, and hopefully that should work. The main issue with this monitor is it doesn't handle 1920x1200 correctly with HDMI signals, so deleting the extension block will remove the HDMI stuff and treat it as single-link DVI.

I may have failed to mention that this use to not occur on older AMD drivers I use to be able to turn on, and play games right away all the time with zero issues on older drivers.

The graphics driver getting disabled usually means the driver crashed. Either there's a hardware problem, or some GPU-related software is causing a problem. If the problem only happens after turning on the computer but not after a reboot, it could be an issue that only happens with fast startup. In that case, try disabling fast startup: https://www.howtogeek.com/856514/how-to-...indows-10/

I am not sure what that means.

I'd like to add detailed resolutions for 640x480, 800x600, and 1024x768, with high refresh rates. I am using a Windows 10 machine with a gtx 770. I have the monitor connected to the video card using a vga cable (from the monitor) and a vga/dvi adapter plugged into the video card's dvi-A port.

Is there something I should be aware of before doing this (e.g., can I risk damaging the monitor?). Any advice?

Usually monitors with an on-screen menu will refuse to display any resolutions that are out of supported range, so there should be no problem as long as you stay within the supported frequency range. CRT monitors are usually limited by the horizontal frequency. Horizontal frequency is just the total number of lines per second including blanking as shown in CRU.

I'm wondering if I just destroyed my laptop monitor.

I have a Lenovo Legion gaming laptop with an Intel GPU and Nvidia RTX2080 GPU that G-sync's to my 1920x1080p laptop screen and only runs at 144Hz.

It's 2023, but I recently bought Lego Indiana Jones (from 2008) on Steam and discovered that it throws an error and won't run on anything higher than 60Hz. There's no way to change the refresh rate in Windows 10 or with Nvidia's control panel, so I was directed to your CRU. I opened it, and clicked "add" under Detailed Resolutions. A new profile popped up and was already set at 1920x1080/60Hz, so I added it and used your restart.exe.

The game now loaded successfully, but it was super dark and there were ghosting issues like crazy. All the underlying screens seemed to appear on top of the game (for example, the title screen was still visible as a ghost image once the game started). I thought it was an issue with the game, so I tried to adjust some settings to brighten the screen, etc. I tried many paths, but much to my horror, upon switching back to 144Hz, my regular Windows desktop retained the ghost images. Even after restarting, my black POST screen showed my desktop icons in a ghost image.

Have I ruined my laptop screen? I reverted everything, but the ghosting is still there.

Help

Leave it on for a few hours at 144 Hz and it should fade away. Panels that don't support 60 Hz are not common, but I'm seeing it more in certain gaming laptops. If it can't handle a standard 1920x1080 @ 60 Hz without freaking out like this, I would consider that a poorly-designed panel. To add a working 60 Hz, you need to copy/paste the 144 Hz timing parameters, and then change the timing to the vertical total calculator, and change the refresh rate to 60 Hz without changing the pixel clock. Since the panel supports G-SYNC, this should work in theory because it increases the blanking while keeping the pixel clock the same, similar to how G-SYNC works.

Thank you for the speedy reply. And I'm glad to hear it will fade with time. I can see it's mostly faded away at this point. Whew.

I think I'll forego playing this old game and not risk any long term damage to my screen (the laptop is from 2019). I suppose I can always connect an external monitor some day. Thanks again for building, maintaining and supporting these tools for so many years. Cheers!

Every time I boot up in Windows 10 it starts up at 640x480@60 resolution and I need to put a restart.exe process (it takes some time to open) in my shell:startup folder to go back to 1920x1080@120, is there any way to fix this so I don't have to wait for the restart.exe to run?

Hi Toasty.

Am using CRU to set a custom resolution on my old crt tv. Using an hdmi to av converter(DISPLAY ID:LTM0000) from my laptop with an intel igpu.

when I set the resolution and switch to it the text is a bit faded and the image gets blurry. I tried all the timings and tried copying the default timing and just modifying the resolution but it all has the same effect.

The only way to get it to display correctly is setting a high refresh rate then choosing the default one in the display settings. now I can live with that but some games opt in for the higher refresh rate with no way of changing it which also has frame skipping and the blurriness.

Thanks in advance.

The only reasons it would be blurry are if there is scaling or some kind of conversion going on. Keep in mind HDMI supports both YCbCr and RGB, which also has limited and full range, so changing that could affect the image. What adapter are you using? What resolutions and refresh rates are you trying to set?

That shouldn't happen unless there's a graphics driver bug. Try disabling fast startup: https://www.howtogeek.com/856514/how-to-...indows-10/

No scaling is applied not sure about conversion.
I tried the setting (RGB,full) in the intel GCC and it made a tad bit better but not the full quality am getting with setting it like the attached image.

Adapter: https://www.amazon.com/dp/B071L4JWWB/?tag=mtests-20#ad
Resolution: 960*540@60 although it happens with any custom set resolution.

Yeah seemed to be the fast startup that was screwing up the resolution, thanks ToastyX.
