I read that entire thread but nothing was mentioned about the 38WK95C-W monitor. The issues seem to be hit or miss depending on which monitor and cables used. I already have my M1 Mac mini. I was hoping someone had experience trying this display out but I guess not. Looks like I might be the guinea pig on this one.Read the post on the main page. Apple is aware of issues with resolutions on the UW displays... no timeframe on when a fix will be released. I wouldn't buy an M1 until said fix is released as it is surely not the only issue with external displays that they have to address.
That definitely seems to be an Apple Thunderbolt issue which I've seen on a number of their machines with LG monitors and single-cable connections. Am disappointed there's still not a reliable fix for it.When I turn off my LG 38WN95C-W UltraWide monitor and later turn the monitor back on, the screen never wakes. I can hit keys on the keyboard and move and click the mouse, but the monitor says there is no input. I’m using a Thunderbolt cable to connect the Mac mini to the monitor. If I disconnect the Thunderbolt cable and reconnect it, the monitor suddenly comes back on, but sometimes this causes the computer to crash and reboot. If I change the monitor source from Thunderbolt to DisplayPort and then back to Thunderbolt, the display suddenly begins working, but the Mac mini often crashes and reboots from doing this as well.
