Connecting 288P6L 4K 3840 x 2160 monitor to XPS 15 9560
I am trying to get 60hz on 3840x2160 resolution to my external monitor Philips 288P6L with my XPS 15 9560.
I was using an HDMI cable but then I bought a USB-c to display port cable just to be able to get 60Hz but It didn't work.
Does XPS 15 9560 support external monitors with the following specs? If not then why?

@sincho HDMI won't work on this system because the XPS 15 9560's HDMI output isn't HDMI 2.0, which is required for 4K 60 Hz. That didn't arrive until the XPS 15 9570, although even there the display would also need to support HDMI 2.0. Many earlier 4K 60 Hz displays don't accept that over HDMI because they were created before HDMI 2.0 existed.
In terms of USB-C to DisplayPort, yes that would allow 4K 60 Hz, and I've run it from even older XPS 15s. In terms of why it doesn't, I see that you have a Philips display. On the Philips displays I've worked with, you need to explicitly enable DisplayPort 1.2 mode in the display's on-screen menu. This should be covered in the display's manual. Have you taken a look at that?

@sincho just fyi, the XPS 15 can support three simultaneous independent display each up to 4K 60 Hz if you have the right hardware to connect them all. On the 9560, since it doesn't have an HDMI 2.0 output, the only way to do that would be to have the 4K built-in display and then two external 4K 60 Hz displays connected to the USB-C/TB3 port through a Thunderbolt 3 adapter or dock.

Explicitly enabling the monitor to work with DisplayPort 1.2 solved it. Thank you very much.
