Hi,
I recently got myself a UHD monitor.
https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=...
However, when I connect to my 3840x2160 resolution laptop and use xrandr (through HDMI, supplied with the monitor) I do not even get an option for 3840x2160. Here is what I get:
I see this in your original email in the xrandr output.
3840x2160 60.00*+ 59.98 59.97 48.00
Does that not indicate that it is running at 3840x2160 at 60Hz?
Sorry, this line was for the laptop screen. But i have realized the issue. A USB-C to HDMI 2.0 is needed, apparently the type-C multihub sold by Dell does not work for UHD. Changing to the USB-C to HDMI dongle has fixed the issue and 3840x2160 is available.
I have a different question however: is it safe to work now with the lid closed or will the laptop overheat? I have switched off the screen for the laptop using xrandr.
Many thanks, Ranjan
