U2717D, P2314H, Input timing not supported
Hi, U2717D is connected to intel UHD Graphics 620 through mDP and its DP out is connected to P2314H DP in. However 2nd monitor (P2314H) is showing the following error,
The current input timing is not supported by the monitor. Please change ... to 1920x1080, 60Hz'
Windows 10 display settings are not detecting the 2nd display, it only shows the 1st display connected (U2717D). I tried changing the resolution for 1st display, tried different refresh rates but 2nd display is still showing the same error. I see the same error for both mirror and extended display modes.
MST is 'on' on 1st display, 2nd display doesn't have the option because it doesn't support DP out.
Any help will be appreciated.

@khayamanjam What system model are you connecting this daisy chain setup to? Just specifying the GPU isn’t always enough. Did you enable MST on the U2717D? Have you tried swapping cables? I ran a daisy chain of two U2717D displays from the mDP output of my old XPS 15 9530 that had an old Intel HD Graphics 4600 GPU and that setup worked fine, even though that GPU is older than your 630 and dual U2717D displays requires more bandwidth than the QHD+FHD setup you’re attempting. So unless your system for some reason doesn’t support DisplayPort MST, I’m thinking that either MST isn’t enabled on the U2717D or you have a cable problem that is preventing the required amount of bandwidth from being carried along the daisy chain. Some very early DisplayPort cables only supported DisplayPort 1.1 bandwidth levels, and you’d need 1.2 for this setup.
