My monitor keeps reverting to the lowest supported resolution.

This problem usually occurs after installing driver updates, however, it can also happen when the PC has been has been sleeping for more than 5-10 minutes (sometimes even less).

Early on, I would restore the proper resolution by shutting down the PC and waiting a few minutes before turning it back on. These days, I can recreate the problem, and/or resolve it, by disconnecting the display's power cable and then reconnecting it after a delay of about 5 minutes.

I've found some people sharing similar problems on other forums:

These guys and others seem to have had similar "No Signal" issues, but mine just seems way more irritating and random. Some have managed to fix the problem with another DisplayPort cable. I haven't tried this yet as I don't have a second DP cable and live far from any store that sells them. I may try to get one when I am next in the city. While the frequency of my problem sometimes varies from the other people whose posts I have found, the posts share a similarity in the model of AOC display.

Some things you can try. Don't make multiple changes at the same time. Try one then wait to see if the problem reoccurs.

This article you linked: Display Adapter Link Failure seems to speak directly to your problem.

They suggested as a troubleshooting step: Disable DisplayPort 1.2 which seems possible with your display.

Download AOC G2460PF User Manual and see page 33, "OSD Setup > DP Capability" (typo "Capaciliby" in English manual). See image:

Test another DP cable

Depending on what monitor drivers you have currently installed, you can,

  • Install AOC's Official monitor driver
  • Install AOC's Beta driver (35-146Hz range)
  • Remove AOC drivers and test with generic Windows display drivers

Download AOC G2460PF Drivers (2015) - package includes Official & Beta drivers

Your display also has power management software "AOC e-Saver", If it is installed, uninstall it. (page 48, in the manual)

I finally found a solution which would be to install the graphics drivers supplied discretely in the manual for this thing. That didn't fix it, but it's the best I've got. Although I found some quicker temporary solutions like re-plugging the DisplayPort cable only need a delay of about 10 seconds or until the "no signal" message disappears. You can also go into the OSD settings on your screen and change DisplayPort version to fix it even quicker sometimes. Not if it wasn't working previously however, then this doesn't work.

I guess the only solution would be to contact AOC which I doubt I'll do since duh. Maybe we need some establish some DisplayPort standards here to make sure this doesn't happen already at the production line or something. Until then, maybe I'll get a new DisplayPort cable and it will work.
