My mac mini late 2012 is having resolution problems?
Tried resetting PRAM and SMC but still nothing works.
Sometimes is goes back to normal. But then suddenly when I startup or wake up from sleep it changes to resolution 800x600 and stays there..
I'm using my Thunderbolt port with my minidisplay port to vga, because i don't have a HD monitor.
Does anyone have a solution?
Hmmm, not sure on the startup, but on the sleep angle...
Well first...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
Then maybe...
See if it's related to this...
The 2012 macs (and later apparently) not waking normally from sleep after hours being in sleep. (noted here ...

The sleepimage file still reappears even if never slept. Delete it (hibernate off, etc) - within minutes its back.

Try this: "sudo pmset autopoweroff 0" and "sudo pmset standby 0"
Oke so i've done all of that. And still didn't work.
This is an output from a way in the last topic:

Currently in use:
standby 0

When i dit the CMD + R, the computer did got the right resolution again, so i tought yeeeeey, but then restarted, did the permision repairs etc. still the same resolution on my desktop.. (800x600)..
What now ? Could the problem be my monitor or my GPU ?
At this point I don't suspect the Monitor or GPU.
Safe Boot from the HD, (holding Shift key down at bootup), can you set a proper resolution in Safe Mode?
Oke so, when booting this time in safe mode, my resolution went back to normal.
I hope this will not occoure anymore.. What was the problem maybe ? Can i still find out?
Well, if it holds doing a regular boot now, my guess would be some Cache file that was corrupted... Safe Boot clears a lot of caches, which are rebuilt on next regular boot.
