Philips 329P1H screen with Asus PN62 mini-PC

Hi,

Unfortunately my brand-new screen does not see any input signal after starting the kernel (Grub displays without problems), and goes into standby mode then. The graphics controller is “Intel Corporation UHD Graphics (rev 02)”.

There is no such problem with my old “ASUS VK266H” screen.

How could I get the new Philips screen working please?

TIA for any hints, Peter

Your display is a UHD docking station monitor - how is it connected to the mini-pc

usb-c cable via thunderbolt 3 port on PC
hdmi cable
display port cable

can the Asus PN62 drive an UHD monitor - many are stuck with FHD max video controller.

UHD is 3840 x 2160
FHD is 1920 x 1080

cvt can tell you what you monitor codes are
xrandr can make you monitor work at a undefined resolution.

this is how I force a FHD to an UHD monitor - the variable D is set to the monitor that OpenSUSE says is the live display.

> cvt 1920 1080

Hi,

Thanks for your reply. I’ve used HDMI (as with my old screen).

Now I’ve changed to USB-C, and it works! So no problem any more. I should have tried that before posting.

Sorry for the noise, Peter

Your HDMI 2.0 have to work with UHD monitors.
Check cable - you need HDMI 2.0+ compatible cable. Possibly your cable is HDMI 1.2a or lower.
Use cables supplied with UHD monitor.

ASUS Mini PC PN62 comes equipped with integrated Intel® UHD Graphics, so you can enjoy watching video and viewing images in stunning 4K UHD resolution. Support for dual displays lets you extend your workspace across multiple monitors for more efficient and comfortable productivity experiences.

The cables seem to be ok. It works well with other PCs and the same monitor.
I’ve also tested the cable supplied with the monitor: no signal.

It seems, that the HDMI output does not support high resolutions, but the USB-C works well.
It’s ok for me.

Thanks for your help, Peter
