XPS 13 4K monitor connectivity

I still can not fix this issue. I have dell adapter USB-C to HDMI but I only get 2195X1235 resolution.

The graphic platgforms shows 3840X2160- 60Hz.

Are there eny new upgrades to solve this issue?

Are you sure that your USB-C adapter supports HDMI 2.0, which is required for 4K @ 60 Hz?  Not all USB-C to HDMI adapters do.  Someone else came here asking a question like this a while ago and posted a link to the adapter they bought.  The adapter specifically said it was good up to 1080p, and I found a link to that manufacturer's updated version that looked visually identical but had a different model number and supported 4K @ 60 Hz.

Ok, in that case you can try updating your system BIOS and your Intel graphics driver, but if that doesn't solve it, I would suspect either a hardware fault or at least an incompatibility with your specific equipment even if the hardware should work and WOULD otherwise work with other equipment, so it would become a case of isolating variables.  For example, have you successfully tested that adapter and cable with another 4K display?  Have you gotten that display to run 4K from any other system?

I have contacted DELL Service in my country (Greece) and tried all that allready (updates, cable and screen testing). They finaly send me an official DELL USB-C to DP cable which gave me a max resolution of 2560X1440.

My screen is Samsung U28E590D.
