Too low resolution on external monitor when switching from HDMI to Thunderbolt (with HDMI adapter)
Heyya!
I have a rather old MacBook pro (details below), that I've been using with an external Samsung monitor (details also below). The external monitor is Ultra Wide Screen with high resolution, and I've been using it by plugging it in to the HDMI port on my laptop. It's been working fine for years.
Recently, my laptops HDMI port has broken down. I can no longer plug my monitor in there. So instead, I bought a Thunderbolt-to-HDMI adapter, and plugged it in via the Thunderbolt port on my laptop.
This works, I'm getting a picture, but the resolution maxes out at 1080p (even with option-click scaled resolution options in display settings), which is way lower than the screens 3440x1440 intended resolution.
Do you know how I can resolve this, and get my secondary monitor up to full resolution?
