Frequently Asked Questions

How do I actually switch between 4K 160Hz and 1080p 320Hz?

Dual Mode is a monitor OSD setting, not a Windows setting. Switching to FHD mode drops the panel to 1080p and unlocks up to 320Hz over either HDMI 2.1 or DisplayPort 1.4; UHD mode returns you to 4K at up to 160Hz on DP and 144Hz on HDMI.

Do I need DisplayPort to hit the full refresh rate?

For 4K, yes: DP 1.4 reaches 160Hz while HDMI 2.1 tops out at 144Hz. In 1080p Dual Mode, both HDMI 2.1 and DP 1.4 reach the full 320Hz, so either cable works. A DP cable and an HDMI cable are both included in the box.

Will this work properly with a PS5 or Xbox Series X?

Yes, over HDMI 2.1, but the console sets the ceiling. SANSUI notes PS5 and Xbox max out at 4K@120Hz and a Nintendo Switch at 1080p@60Hz, so the 160Hz and 320Hz modes are for PC sources.

Is the HDR good enough to be worth using?

It is HDR400 with 400 nits peak brightness, which adds wider color handling but not the contrast punch of a local-dimming display. The 93% DCI-P3 and 126% sRGB coverage is the stronger reason to buy this panel for color work.

Can I mount it on a monitor arm, and what warranty comes with it?

It uses the standard 100x100mm VESA pattern, so any common arm fits; the included stand pivots -90 to +90 degrees, swivels 25 degrees each way, tilts -5 to 20 degrees, and adjusts 130mm in height. SANSUI lists 30-day money-back and free replacement from the order date plus lifetime technical support.
