xrandr doesn't detect hdmi on ubuntu 20

i bought new laptop

install ubuntu and connect HDMI...dose not work.

and i found this

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm 1920x1080 77.00* 

xrandr doesn't detect hdmi, normally other ubuntu detected HDMI-1 or something i'm ask on google, that cause is *-display UNCLAIMED

 *-display description: 3D controller product: GP107M [GeForce MX350] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:95 memory:fb000000-fbffffff memory:b0000000-bfffffff memory:c0000000-c1ffffff ioport:f000(size=128) memory:fc000000-fc07ffff *-display UNCLAIMED description: VGA compatible controller product: Renoir vendor: Advanced Micro Devices, Inc.

you can see a part of *-display UNCLAIMED

so i'm looking for amd or ati or renoir or radeon graphic drivers, i did install them, did everying, does not work.

could you solve it?
