Hello owmyeyes, I just bought this laptop based on your post above. For the moment looks like I have minimal symptoms if I work on it which is GREAT, but if I'm connecting it to my external monitor, the "nvidia GPU only" mode is grayed out and "optimus" is selected by default.

This is not good because I think the signal is still bypassed via the iGPU and I'm getting dizzy with eye strain.

Do you use an external monitor? If yes, how did you make sure the "nvidia GPU only" mode is active and survives after the laptop restart?

Thanks

    necreatul I think the best mode is disable igpu on devices manager or connect tò external monitor by hdmi

      necreatul I am glad to hear that the laptop seems to be working for you! Because it's a fairly new model, I hope to use it for a long time. I am careful to NOT update the NVIDIA driver to avoid the risk of a software update messing up my working configuration.

      Sorry, I don't think it is possible to bypass the iGPU when you use an external monitor using the USB-C ports. It is a hardware limitation and I can't think of any way to get around it. I have the same issue and my solution is to use only the laptop screen for now.

      I recently ordered an Onyx Boox Tab Ultra C color e-ink tablet. I plan to use it as a secondary display wirelessly using Spacedesk software - I will update once I test it out.

          owmyeyes Hello, yeah I also tried to make it bypass the iGPU but with no luck. The second display is giving me headaches so I think I'm gonna return the laptop. Although the screen is super nice, it is too small for my work as UX designer.

            I have another update - I could not use the Onyx Boox e-ink device at all, either as a secondary monitor or as a standalone eReader.

            My laptop (Lenovo Slim Pro X) is still working fine but I can't use any external display with it. I do need a larger screen for work so I got a used desktop with i5-12600K CPU and RTX 3060 Ti GPU. I tried a number of monitors that were uncomfortable until I settled on a Sony KD-43X77L 4k TV to use as a computer monitor. I still had to change a bunch of settings on my PC as well as the TV menu but l I finally have a usable setup.

            I made a new post with more details here: https://ledstrain.org/d/2559-sony-kd-43x77l-tv-working-as-a-monitor
