Heart rate line not clear and grey on MacOS 4K

[Arjen_Woortman (Arjen)]

On my Mac Mini M4 (4K setting on 4K TV and 60hz) the heart rate line in the bottom graph is clear anymore and turns from grey to red all the time. The line seems a lot thinner as well. Any others with the same “problem”? Had this already on the V1.82 software earlier this week and bluetooth connection is fine according to Zwiftanalyzer.

See (not very clear) picture below. The screenshots from Zwift show the graph line without a problem.

Hi, @Arjen_Woortman, welcome to Forums! I’m Francisco from Zwift Support.

It’s nice to see everything in higher resolution clearly. I got you. Thanks for sharing this concern with us.

You highlighted two important aspects that I want to address in my response. You’re operating with an M4 chip and game version 1.82.

Zwift released a new update recently in order to address this type of situation: macOS : 1.83.2 (1.0.140279). February 6.

• macOS: The Ultra graphics profile is now enabled for devices with the following chips: Apple M4 (all versions), M3 Max, M3 Pro, M2 Ultra, M2 Max, M2 Pro, M1 Ultra, M1 Max, and M1 Pro.
• macOS: The High graphics profile is now enabled for devices with the following chips: Apple M3, M2, and M1.

Can you give it a try and test it with a new release to see how it goes: Updating Zwift?
