I have a XPS 9570 with an intel i7-8750h and 1050ti Max-Q graphics card and recently bought 2 144hz monitors. The first one I returned because I thought there was something wrong with it when I changed the refresh rate to 144hz, but upon receiving the new one I’m getting the exact same problem. I was displaying the monitors out of the HDMI 2.0 port instead of a display port, as I don’t have a dedicated display port on my laptop. However, I have a USB C that acts as a display port 1.2 which may allow for higher bandwidth than the HDMI port. Given that I don’t have a USB C to Display port adapter at the moment, I haven’t had the chance to test this yet. However, I have also read online that because my laptop uses Nvidia's optimus system where all of the io ports are connected to the intel integrated graphics card, it may not be able to support a 144hz output. My thought after this was to perhaps disable the integrated gpu so only my dedicated gpu will be in use at all times, however I have also read that due to this system, the dedicated gpu won’t be used unless there are processes that call for higher performances, preventing me from having any display at all, so am not sure if that is an option.
The problem that occurs whenever I set my display to 144hz is shown in the photo below. To explain, the leftmost 1/5th~ish of the screen moves to the very right of the screen, and everything else shifts over to the left. At this point, the screen itself is successfully at 144hz. This does not occur at 100hz or 120hz, and the monitor operates correctly at these refresh rates.
