In terms of sheer bandwidth, HDMI 2.1 48Gbps easily handles 4K 120Hz with full HDR and no compromises on color. It is also capable of 4K 144Hz with tweaked settings if you prefer a higher framerate.
These changes to color are not noticeable to most people and the image still looks great. It’s a good tradeoff for those who prefer higher framerates.
This is the first time HDMI has been able to work in such a high refresh. You can also opt for 1440p on HDMI 2.1.
It’s all a matter of which you prefer, color fidelity or refresh. We recommend going for higher frame rates, especially if your focus is reflex-based shooters.
Additionally, monitors such as the MOBIUZ EX3210U support digital signal compression technology or DSC, which allows for 4K 144Hz to transit via one DisplayPort 1.4 connection, despite DP 1.4 being around for quite some time. Note that the graphics card you choose should also support DSC, but that’s not a problem because nearly all video cards released over the last couple of years have this technology. If you choose to game in 4K 120Hz, then DSC isn’t needed and DisplayPort 1.4 will work perfectly.
