Asus Zenbook 13 OLED (2021) lacks 4K@120Hz display on HDMI connection.
Basic premium cables just imitate cheaper versions. This laptop offers two 2.1 ports, but only the second one supports 4K at 120Hz—it's an extra feature. It has one FRL port (slow port) labeled HDMI 2.0 and another HDMI 2.1 port (48Gbps). Experiment with all ports to check performance. Even in 2.0 mode, the TV should handle 120Hz; otherwise, ensure it's enabled on the TV as well.
The cable comes from HAMA and is listed on their site. It seems suitable for my needs right now, though I reviewed the HDMI video tutorial. My laptop only has one physical connection, which likely means it supports both 2.0 and 2.1 standards. I looked into the display settings and found it uses 8-bit YCbCr444 with SDR, without HDR enabled. There’s no compression option shown, but I’m curious if I can adjust it in Windows to enable 4K at 120Hz. I checked the TV ports and one supports eARC, so I assume that port also handles 4K@120Hz. It might help if I test it now. Regarding CPU/iGPU compatibility, I’m not sure yet. I’m planning a PC build for testing purposes, hoping to get the RX 7000 before its release and lower prices for the 6000 models. Thanks for the info so far!
I discovered the issue: my 43-inch TV doesn’t handle 120Hz. I checked it at a friend’s place with a 55-inch screen, which worked fine. Samsung confirmed this discrepancy.
