What works & limitations
- 3440x1440 at 60Hz without limitations
- 3440x1440 at up to 85Hz at 8-bit color on some monitors
- Standard 1080p and 1440p resolutions at full refresh rates
- 3440x1440 at 100Hz at full 8-bit color exceeds HDMI 2.0 bandwidth on most monitors
- 10-bit HDR at ultrawide 100Hz is out of range for HDMI 2.0
- Achievability at 100Hz depends on whether the monitor firmware allows chroma subsampling over HDMI 2.0
- DisplayPort is the more reliable path for ultrawide at high refresh rates
- Check your monitor manual for HDMI refresh rate limits at native resolution
