I have two 1440p (KOORUI) monitors connected to my laptop by using a MOKIN MODK1901 docking station. If I connect them using one HDMI and one DP ports they work just fine.
When I connect both of them by using DP ports only, just one is detected and gets image. The first I connect is the one that works, but any of them works independently, so monitors and cables are fine, but only one works when both are connected via DP interface (the first one connected).
My laptop is an ASUS ProArt PX13, that supports 40GB Thunderbolt, it has the integrated Radeon GPU and a NVidia RTX 4050 discrete GPU, so it can manage two 1440p monitors, actually it works when I connect one DP and one HDMI through the MOKIN.
Is this a limitation of the doking station, or is it something else that I can configure or fix?
UPDATE:
DP1 works
DP2 works
HDMI works
DP2 + HDMI works
DP1 + HDMI (only DP1 works)
DP1 + DP2 (only the first one connected works)
