Hi ToastyX
I'm trying to configure the following environment:
- Samsung WQUHD Monitor 34" (LC34G55T) - Firmware is up to date!
- Dell Inspiron 15 3530 - Core i7 1355U
- Intel Graphics UHD P750 (Intel® Graphics Driver 32.0.101.7082 (whql certified) - Dec 8, 2025
- Video output: HDMI 1.4
- Windows 11 64 - 25H2 (26200.7171)
I'm trying to reach the top resolution I can: 3440x1440 at 60Hz ... but Dell limits it to 1920x1080!
Until few days ago, I was using an old driver version (30.0.101.1692), which allowed the 3440x1440@60 (HDMI 1.4) resolution. I had an update from Windows/Dell this morning and the option for this resolution disappeared, even from old driver. I've checked the Events in windows, there were some instances of updates, but not further details. I notice a lot of errors (Event Viewer), below.
I run a clean driver install to latest version (32.0.101.7082) and then I tried CRU 1.5.3. I followed the CRU instructions for my configuration. I've used CVT-RB for timing. I also tried CVT-RB2 and manual set.
Well... even following the correct steps it's not enabling the 3440x140 resolution.
Any clue or hint to re-enable 3440x1440?
Or... Did Dell find a way to block EDID edition?
Thanks in advance!
