I got this 4750U in the T14. The CPU performance is great, but the iGPU is terrible when connected to an external 2160p60 screen. Animations for stuff like maximizing window have 2-3fps tops. iGPU from intel in 10510U manages 10+ fps. (5.8 kernel, Gnome 3.36).
- Roritharr 6y agoThis must be a software issue in Linux, I don't have anything close to these problems in Windows. Perfectly fluid with 2 external 2160p60 screens connected. WSL2 is amazing btw.

- qz2 6y agoGot a bottom end T495s here that quite happily handles an external 4K screen with Ubuntu.
