Hey everyone, I have an Acer Predator Helios 300 G3-571 laptop. I broke the original screen and had it replaced. Now it’s only showing a max resolution of 1366x768 even though the laptop and screen can handle full HD 1920x1080. I’ve tried everything I could think of to force it to recognize the 1080p setting but no luck. I’ve used CRU, disabled the integrated GPU, tried registry edits, manually added resolutions, messed with EDID files… I even tried NVIDIA Control Panel, but it has limited options. BIOS isn’t helpful either (old version, very basic). Running out of ideas, so I’m hoping for help here.
This can happen sometimes after screen replacements if drivers, BIOS, or EDID settings don’t match up right. Try updating both the Acer and NVIDIA drivers, check Windows and NVIDIA display settings for the correct resolution options, and see if Acer has a BIOS update.
If possible, test it with an external monitor. If it works there, it’s probably an issue with the screen or the connection. You can also try using CRU to adjust EDID data; that might do the trick.

Thanks for replying! I don’t have an external monitor to test it right now. I’m pretty sure I have the latest drivers for NVIDIA and BIOS, but I’ll double-check. I tried forcing a custom resolution with CRU, but it didn’t work. I also tried editing the EDID data, but it’s a bit hard for me to figure out. I tried using ChatGPT for steps, but I kept running into issues, like not being able to retrieve EDID data from PowerShell (the command didn’t work). I tried using SoftMCCS to save the EDID file, but when I hit save, it just disappears and I can’t find it anywhere.

If you don’t have an external monitor, no worries. Let’s focus on sorting out the EDID info. Since CRU and EDID editing can be tricky, here are some tips:
-
Run CRU as an administrator, set the custom resolution under ‘Detailed Resolutions,’ and then restart. Sometimes, you need to reboot after making changes or restart the graphics driver using the ‘restart64.exe’ file in the CRU folder.
-
When saving the EDID file, try saving it to a specific folder you can find easily, like your desktop. If that doesn’t work, SoftMCCS might not be compatible with your screen.
-
You could also try using other EDID tools, like Monitor Asset Manager or ViewSonic’s EDID editor from EnTech Taiwan; these might help with EDID extraction.
Some users with the same model might have shared a working EDID file on forums, so that’s an option too. Just be sure it matches your display model if you go that route.

I kind of went crazy and deleted all the registry values related to display settings… about to restart and hope it doesn’t blow up, fingers crossed!

Haha, going all-in on the registry… love the dedication! Let’s hope there’s no explosion when you restart. If it doesn’t work, you might want to use Windows system restore to go back a bit. Fingers crossed for a smooth restart… let me know if it survived! 
@Brett
It survived, but still no luck with the resolution. I feel like I’ve tried everything now. Every app and tool I use to check the display capabilities says it should support 1920x1080, but I just can’t get there. I even used DDU (Display Driver Uninstaller) to completely remove both NVIDIA and Intel drivers, but now the laptop’s using some basic Microsoft drivers. Running out of ideas and haven’t been this frustrated in a while… and I used to play League of Legends 
Try using more specific titles next time. It helps others understand the issue at a glance. Thanks!

Got it, sorry!
