Custom Resolution Utility (CRU)

[cyrb]

Just an update - solved my issue (regarding CRU's changes not taking effect). It was an Intel Driver issue. Sorry for the confusion.

The laptop has both a NVIDIA GeForce 840M as well as "Intel HD Graphics", integrated graphics. The manufacturer's Intel driver is old and hasn't been updated since 2016. And it refused to allow me to install the latest generic Intel drivers (it complains that the new driver hasn't been approved by the vendor).

With the original driver, deleting "Default extension block" does nothing. However I was able to force-install the latest Intel driver through "Device Manager". This seems to solve the issue for me. CRU's changes are working with it. It seems CRU fails to work on the old drivers, but works fine on the latest ones from Intel.

It's a bit puzzling because GeForce 840M is supposed to be my primary "graphics processor". I guess for some reason, Intel is the 'master' driver and controls the initial resolution switching before invoking the secondary driver.

I did encounter a strange issue though. When adding the custom resolution 1278x720 (without using it), and restarting via restart.exe, it sometimes didn't come back after going black. I had to hard-reset. Other resolutions seem fine such as 960x540. Although restart.exe switches to black more than once when executed, whereas the Intel-supplied software that adds custom resolutions only switches to black once.

Also, CRU doesn't seem to see the custom resolutions added by Intel HD Graphics Control Panel, but upon saving in CRU, it erases the custom resolutions set by that software.

Cheers - great software
