I have a Lenovo Legion 5 Pro with Ubuntu 22.04 with an external monitor (Lg UltraGear 24GN650). I connected to my laptop and the monitor works but laptop is 4k 2560 x 1600 and my monitor is 1980 x 1080. I need to scale my laptop a bit so that I can see things a bit bigger than they are but as soon as I do that, the monitor gets zoomed in too even though in the settings, it is at 100%.

Laptop Spec

**Processor** AMD Ryzen™ 7 5800H Processor (8 Cores / 16 Threads, 3.20 GHz, up to 4.40 GHz with Max Boost, 4 MB Cache L2 / 16 MB Cache L3)

**Display Type** 40.64cms (16.0) WQXGA (2560x1600) IPS 500nits Anti-glare 165Hz 100% sRGB Dolby Vision HDR 400 Free-Sync G-Sync DC Dimmer

***Memory*** 16 GB SO-DIMM DDR4 3200MHz

**Graphics** NVIDIA® GeForce RTX™ 3060 6GB GDDR6

**Wireless** Wi-Fi 6, 802.11ax 2x2 Wi-Fi + Bluetooth® 5.1, M.2 Card

Note that my laptop is in dynamic graphic mode so both my Nvidia and Amd integrated GPUs are working.

After changing it to discrete modeThe issue gets solved if i switch to Discrete mode, i.e NVIDIA but now I can't control my screen brightness.

I had the same issue when I had Ubuntu 20.04 and I couldn't fix it.Screen Brightness issue I had with 20.04 (The solutions didn't work and the monitor didn't work at all). That is why I switched to 22.04.

While switching between monitors I also notice considerable amount of lag.

Please help me. :)
