Hello! I recently put together a small workstation that should (based on the hardware specs) support dual 4k@60Hz displays, I’m unable to set both displays to 60Hz.
When I connect a single display (either DisplayPort or HDMI), I can select 3840x2160 @ 60.00 Hz. However if I connect both displays, I can select 3840x2160 @ 60.00 Hz for the DisplayPort-connected display, but only 3840x2160 @ 30.00 Hz for the HDMI display.
I’ve tried using a different HDMI cable just in case, but that didn’t make a difference.
Any idea of what I might be missing? Thank you!
Hardware:
-
Intel i5-12400 (UHD Graphics 730)
- Max Resolution (HDMI)‡ 4096 x 2160 @ 60Hz
- Max Resolution (DP)‡ 7680 x 4320 @ 60Hz
-
Asus Pro H610T D4-CSM
- 1 x DisplayPort (Supports max. 4K@60Hz as specified in DisplayPort 1.4)
- 1 x HDMI® port (Supports 4K@60Hz as specified in HDMI 2.1)
