I would check the rating on your HDMI cable, the older ones aren't supposed to be able to support greater than 1080p rates, so if you cable is very old it may not support the speed.
There is probably something written on the cable ends and/or the side of the cable itself. Mine says high speed on the side which indicates it can support at best 4k-30 and is an hdmi 1.4 cable (assuming the ends themselves are also compliant) but nothing more. see: https://en.wikipedia.org/wiki/HDMI On Tue, Apr 21, 2020 at 1:51 PM stan via users <users@lists.fedoraproject.org> wrote: > > On Tue, 21 Apr 2020 12:40:30 -0500 > Ranjan Maitra <mai...@email.com> wrote: > > > On Tue, 21 Apr 2020 12:17:24 -0500 Ranjan Maitra <mai...@email.com> > > wrote: > > > > > Hi, > > > > > > I recently got myself a UHD monitor. > > > > > > https://www.amazon.com/dp/B07JXCR263?tag=aboutcom02lifewire-20&linkCode=ogi&th=1&psc=1&ascsubtag=4138562%7Cneef17e57867342f0bc4b3af20a9ba60801 > > > > > > 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.
