I don’t like HDMI for computer output, it’s had more problems than DisplayPort, but I’m working with what I have. Does anyone have experience with solving issues with HDMI and QHD monitors?
I have a new 27" HP Z27n G2 monitor and I’m having trouble getting its native resolution (2560x1440) on one of my Macs via my desired connection path.
When I connect this way: 16-inch MacBook Pro, TS2-to-TS2 adapter, TS2 cable, CalDigit Thunderbolt Station, HDMI cable, Z27n G2, the best resolution I can get is 1920x1080. If I instead use an Apple USB-C HDMI adapter, I get the native resolution. This monitor replaced an old 24" Dell Ultrasharp that was 1920x1200 over the same connection path.
The Thunderbolt Station is supposed to handle up to 2560x1600 so I was going to write to CalDigit but first decided to try connecting it to a 13-inch Late 2013 MacBook Pro. Connected to the 13" MBP, I get the monitor’s native resolution!
I don’t see how the TS3-to-TS2 adapter could be the source of the problem but I don’t have another another adapter or cable to test. Just because I had them, I did try a different HDMI cable (no difference), and a 3rd party USB-C HDMI adapter (like the Apple one, it supports the monitor’s native resolution).
