NOTE: If you intend to connect dual monitors above 4K 60Hz, such as dual 5K 60Hz or 6K 60Hz, your monitors and host GPU must support DSC 1.2 (Display Stream Compression) and DP 1.4 HBR3. Apple M1, M1 Pro, M1 Max & M1 Ultra support DSC 1.2 & DP 1.4 HBR3. Please note that the LG UltraFine 5K monitor does not support DSC.
In addition, if you intend to connect a single display above 4K 60Hz your host GPU and monitor must also support DSC 1.2 and DP 1.4 HBR3.
*Some Windows PC manufacturers have decided to restrict functionality on their Thunderbolt 3 and USB-C ports such as charging and monitor compatibility. Check to see if your PC supports external monitors.
*Intel MacPro 2019 with Radeon Pro 580X or Vega MPX Module can NOT support 6K (such as Apple Pro Display XDR) behind TS4. It is limited to 5K only. To use Pro Display XDR at 6K behind TS4, please upgrade to the MPX Module that can support DSC. For the DSC support, please check with GPU’s spec or check https://support.apple.com/kb/SP797
**Some refresh rates require DP 1.4 HBR3 and DSC 1.2 support from host GPU and monitor.
Some Thunderbolt 3 hosts that only support DP 1.2 will be capped at a lower resolutions & refresh rates.
The bit/color depth may vary in order to support higher refresh rates.
The support of higher refresh rates may vary due to OS updates.
*** Current Mac computers, including Apple Silicons M1 / M2, can only support up to HDMI 2.0b over its Thunderbolt ports. As such, resolution will be limited to 4K 60Hz when using an HDMI adapter. If higher refresh rate is required, please use USB-C to USB-C or USB-C to DisplayPort or DisplayPort to DisplayPort connection.
