Hello,
I just recently purchase a Samsung U32J590UQ 32 inch 4K monitor for my Alienware m15 laptop. It is a very nice display, but I am having an issue with it. My laptop is running Windows 10 Pro 64-bit and has HDMI, miniDP and USB-C ports to connect monitors. I have 2 x Samsung B2230 1920x1080 monitors (one on USB-C and the other miniDP) and the new Samsung U32J590UQ connected to the HDMI port (using the included HMDI cable). The high performance nVIDIA card runs the HDMI and miniDP ports and the built-in Intel card runs the USB-C graphics port.
I have the screens set up just now, all with the correct native resolutions with the configuration 2 3 4 on top and 1 below 3 (2+4 = B2230, 3 = U32J590UQ, 1 = laptop 1920x1080 display).
Now, to the problem... If I shut down the laptop and restart it, all monitors remain in the same configuration for a few seconds after the desktop loads, then the U32J590UQ changes to 1920x1080 and display 2 is moved to below display 1 in the "Display Settings", "Rearrange your displays" box. Then I need to click on display 3 (U32J590UQ) and change the resolution back to "3840 x 2160 (Recommended)" and move display 2 back to the left of display 3. Also, the main display is reverted back to the laptop display so I need to change it back to the U32J590UQ as I like it as my main display.
Before I connected the U32J590UQ, I had no issue with the display configuration changing each startup. I have a different display configuration at my work too, and it also configures correctly each time I connect. Basically, there were no issues at all until connecting the U32J590UQ monitor.
