Watch out for misleading HDMI 2.1 port specs on some of the more expensive 2023 TV models

[Redaktion]

Thanks to a more lenient HDMI licensing administration policy, TV makers can now advertise HDMI 2.1 compatibility, even if some TV ports are actually HDMI 2.0 without 48 Gbps speeds. Only LG and Samsung offer 4x HDMI 2.1 ports on this year's OLED models, while other top brands like Sony and Panasonic are still limited to only two HDMI 2.1 ports.

And if this is not the case, this is a 100% warranty case. Because the quality of the goods is always ahead of only one person - the buyer, the one who pays the money.

For example, AMD marketers, in the specifications of Zen4, modestly fell silent about the bandwidth  of HDMI 2.1 and DP2.0 (2.1) ports, but a technically competent consumer, will note that DP2.0 contains support for only UHBR10 mode by AMD, i.e. DP2.0 the port is cut off by half  of bandwidth 80Gbps and gpu part of Zen4 NOT support 8k monitors in lossless mode (4:4:4 w/o DSC loss compression).
