LG在2022年度CES亮相的C2機型號稱是全速HDMI 2.1
LG C2 48Gbps HDMI 2.1

[As usual, every HDMI port on both the G and C series will offer full HDMI 2.1 capabilities — and this time LG really means it.
Whereas the company’s TVs have been limited to about 40Gbps of HDMI bandwidth in recent years, for 2022 it’s using the whole 48Gbps pipeline.
You’ll also still be getting the usual 120Hz 4K gaming, variable refresh rate, auto low latency mode, and so on.
It’s worth noting that LG is already being surpassed in a few of these areas, however;
some of Samsung’s just-announced 2022 TVs support VRR up to 144Hz for PC gamers. ]

隨手翻譯：G及C系列上的每個HDMI接口都會提供完整HDMI 2.1功能，
這回LG顯然是認真的。鑑於該公司往年機型的HDMI頻寬被限制到40Gbps,
2022年這次使用完整的48Gbps通道。
使用者會享受到該有的4K 120Hz 遊戲體驗，VRR，自動低延遲模式等功能。
必須提到的是LG在某些領域已經被超越了，
比如某些三爽剛公佈的2022電視機種為電腦玩家提供最高144Hz的VRR性能。
