The Korean Wasabi Mango is the first 4K IPS panel to support 120Hz refresh rates.
The UHD430 is additionally being marketed with HDR support, though it’s the entry-level 400 nits brightness achieved here. Some high end panels are now offering very bright 1000 nits but there are not many of them available yet.
- 3840×2160 120Hz
- 400 nits
- 1200:1 contrast
- 4:4:4 chromaticity support
- 3x HDMI, 2x DisplayPort
Realistically this panel needs DisplayPort 1.4a support to be able to handle the bandwidth needed.
I am expecting to see more 120Hz panels to become available over the next few years as gaming demands for faster action are pervasive.
