I recently bought a 24" AOC G2460PG monitor. I mainly use it with a Windows 10 gaming PC which works great. I however have a work laptop and a personal laptop running Ubuntu that I've tried to run it on but it fails to do EDID detection and only gives me the options for 1024x768, 800x600, 640x480. The native resolution is 1920x1080. Some info about my setup:
Both laptops are model Thinkpad T440s. They have a mini display port and the monitor only outputs regular display port so I'm using a simple adapter. One laptop is running Ubuntu 14.04. The other was running 14.04 but is now running Ubuntu MATE 16.04, same issue. I dragged out an older Thinkpad with a full size displayport plug just to test it on ubuntu and the same thing happened, so it seems unlikely to be the adapter. All machines are using onboard video, but I know its capable of pushing 1920x1080 to an external monitor because day in and day out I use an old samsung with that resolution via a DVI to mini display port adapter. I've found several threads here for generating a modeline and feeding it to xrandr and then setting the monitor to it but any resolution over 1024x768 will just turn the monitor on standby and it will say that it lost the signal.
Is this a driver thing? I feel like if I got EDID working properly I'd be able to choose the right resolution. I don't really know where to go from here. I haven't contacted the manufacturer yet because I'm certain they'll take the first opportunity to say they don't support linux and drop my case.
New AOC G2460PG monitor, no EDID, only takes 4:3 resolutions
