The Asus ProArt B550 Creator offers dual Thunderbolt 4 Type-C and 2.5 GbE ports, along with a mid-range $299.99 price. If you can work with limited speedy internal storage, this is a solid option. Otherwise, the X570 platform may be a better choice due to the additional PCIe lanes/storage flexibility.

I'd kindly request from
Joe Shields to communicate to Asus and challenge them on the marketing claim that this motherboard hosts "HDMI 2.1" port on the back panel. They say, quote: "HDMI 2.1 (4K60)". "4K/60" is vague enough to be considered a feature specific to HDMI 2.1 spec.
- 4K/60 10/12-bit RGB image would qualify as HDMI 2.1 feature, becasue it requires more than 18 Gbps of bandwidth for transport and this can only be done with new FRL protocol introduced by HDMI 2.1 spec
- 4K/60 8-bit RGB can work over older TMDS protocol, which is standard HDMI 2.0b
So, not all "4K/60" signals are the same and can be delivered both by older TMDS protocol and newer FRL, depending on bit depth and required bandwidth.
I have challenged them twice via email and they have never answered my questions as regards to which specific features from HDMI 2.1 spec does this HDMI port support and how those features are anabled. One member of technical support team told me that the port supports older 1.4 spec speeds (10.2 Gbps), which is closer to truth on Vega platform.
There could be only two ways how HDMI 2.1 can work on a motherboard:
1. APU natively outputs FRL faster signal. FRL is core part of HDMI 2.1 spec
No current APU from AMD, including Ryzen 5000G series, support FRL signalling. Those APUs output HDMI signal by using older TMDS pixel clocks by Vega iGPU. By the way, Intel's CPUs neither have this capability.
2. APU is helped by additional level shifter/conversion chip DP 1.4-HDMI 2.1
Close shots of the motherboard in TechPowerUp review do not show that such chip is installed. So, has Asus installed a level shifter/converter HDMI 2.1 chip on this motherboard to enable FRL signals up to 40 or 48 Gbps? Can they answer this question, please?
If the motherboard does not have this enabling chip, Asus must remove "HDMI 2.1 (4K/60)" from marketing, as such claim would be meaningless and misleading the public. Whoever has this motherboard, please challenge them to provide with the evidence that this port can operate FRL protocol and deliver images with bandwidth above 18 Gbps.
