Text rendering worse on eGPU?
Has anyone else with a 4k monitor noticed that text in some applications tends to look different when the display is connected to an eGPU and a Thunderbolt 3 MBP vs the internal graphics?
In most apps it's not really noticeable, but when I'm running Visual Studio Code and my favorite color theme (Kimbie Dark) on a Dell P2415Q 4k monitor, the red text in particular is noticeably 'pinkish' and blurry than when connected directly to the MBP's internal graphics. It's bad enough that I usually prefer coding connected to the internal graphics. Unfortunately the MBP chassis runs noticeably warmer and I lose hardware acceleration for other apps when doing this, so it's not ideal..
I'm using a 2018 13" MBP and an RX 580 with the Breakaway Box, btw. Also have a 32" BenQ 2560x1440 monitor connected to the eGPU that doesn't have this problem.
Update: Installing Mojave fixed it.
Dark mode FTW 😎
Even though you already fixed this issue I just wanted to post my own findings that might be useful to someone else.
In High Sierra I noticed color fringing around text when using an RX 580. It was so bad in Xcode that I considered it unusable, it was worse with a light on dark theme but even with a white background theme (gross) it was still unusably bad. I ended up returning my 580 and upgrading to a Vega 56 for game performance reasons and found that it actually fixed the color fringing issue. So apparently text rendering quality can actually vary from card to card.
