    That makes sense. G-Sync on FreeSync monitors was enabled through drivers at beginning of this year.

    Interesting, I wonder if the N173HHE-G32 would then allow for Gsync. I dont desire it personally, just a curious scenario.

    Anyways a MUX laptop list would be dope.

    I believe MSI GT-series laptops using that panel such as the GT73 and GT75 do support G-Sync. Installing the same panel in a different laptop however would not allow you to enable G-Sync.

    It's no loss to me, I plan to get another one anyways to replace my glossy panel.

    Yeah it's a great panel, G-Sync or not.

    Didn't read this whole thread, but I assume the Lenovo Legion Y545 has been mentioned as having a MUX. What I really like about this particular laptop is that you can change which mode you want through either the BIOS or Lenovo's Vantage software.

    Hi there, this is newbie.
    You said that tested on 165hz 1440P, both optimus mode and DGPU-only-mode, and you see that there were no difference about input lag in both case.
    I have a question. When you tested the input lag of Optimus mode, Did you check the Optimus laptop's DGPU was certainly activated and currently running?

    If you didn't, the test could be in wrong condition.
    The test is to measure the input delay added by Optimus mode at using DGPU.
    So, It shoud compare the following case : (DGPU-only mode by muxed) vs (DGPU activated mode by optimus). Should NOT the case : (DGPU-only mode by muxed) vs (DGPU deactivated, but IGPU is running mode by optimus).

    Did you tested (DGPU-only mode by muxed) vs (DGPU activated mode by optimus) certain?
    Your no-input-delay opinion is very surprising and i also wonder how the test was proceeded.

    Thanks for listening my poor english.

    When usin gan external high refresh rate gsync monitor, you have to disabled and re-enable the iGPU to prevent stuttering because of a driver bug. This is a sign that the iGPU is active and running in optimus mode (control panel are accessible now as well which arent available in discrete only mode). I double checked this by using the internal monitor itself but because of the 60hz limit, it would be harder to perceive input lag if it was there so it wasnt my primary test case.

    I did the test by putting my camera in slow mode recording and recording my mouse click and screen in one single composition the click and reaction on screen for both in optimus and without optimus enabled. After this I counted the frame between the click and action on screen in Adobe premiere and there was no perceivable input lag except for some small variance without an identifiable pattern. Optimus in the early days had input lag but they have been improving it for years now. Some people claim input lag on the RTX series but currenly I dont have an RTX laptop with a MUX switch.

    Anybody ventured into these settings on the Razer Blade Pro series? I'm scared I'm just gonna have a black screen brick if I mess with these settings but I would love to be able to set up VFIO passthrough on a Linux host, currently in Optimus mode I cannot get it working.
