HP Envy 34c resolution maxes out at 1920x1200

[Luis Arias]

Using get-edid, the best resolution is "Mode 0" below, but this doesn't show up in the Display systems settings panel.

This is read-edid version 3.0.2. Prepare for some fun.

Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.

Looks like i2c was successful. Have a good day.

[Luis Arias (kaaloo)]

The only way to get a workable system is to move back to a 4.4 kernel. I tried that before and still experienced some issues but trying this latest 4.4 build.

[Daniel van Vugt (vanvugt)]

Since your system has hybrid graphics (both Intel and Nvidia GPUs) it's unclear which monitor connectors are connected to which GPU. The answer varies between laptop models...

If we assume the answer is that your HDMI port is connected to the Intel GPU (which would be pretty normal) then this is a duplicate of bug 1606103.

If your HDMI is connected directly to the Nvidia GPU then that's an Nvidia bug.

[Daniel van Vugt (vanvugt)]

Yep, Xorg.log seems to suggest the HDMI port is on the Intel output. So possibly a duplicate of bug 1606103. Although I would not have expected going back to kernel 4.4 would help (!?).

[Luis Arias (kaaloo)]

Weird yes! Thanks for the feedback though. I'm on the 4.4 kernel now and wanted to report this which is perfect. I'll switch back to the stock linux-generic in a bit to run the same and post the output here if that helps.

I'm on the 4.9 kernel today with the following .xprofile. Much less flicker but it still comes up every once in a while.

xrandr --newmode "3440x1440" 196.25 3440 3600 3952 4464 1440 1443 1453 1468 +hsync -vsync
xrandr --addmode HDMI-1 "3440x1440"

[Luis Arias (kaaloo)]

Back to 4.4.38 because flickering eventually led to a complete freeze.
