I'm trying to use a BenQ Zowie XL2411 as a primary (and only) screen for a laptop, yet I can't seem to be able to get it to run at the maximum 120/144hz at native resolution. After playing around with CRU and doing quite a bit of experimenting I've found out a couple of things:
1. The laptop only has an HDMI port.
2. The laptop is always only utilizing the integrated AMD graphics, despite having a dedicated AMD GPU.
3. I have tried using a pure HDMI connection and a DVI to HDMI connection. The DVI one seems to perform worse, has different default resolutions, yet the problem is exactly the same.
4. The monitor's OSD doesn't seem to recognize resolutions above 60hz when connected via pure HDMI (windows does), and when connected via DVI to HDMI it says "Optimum Resolution 1920x1080@120" despite me not being able to increase it to that. Doing it through the DVI will only show a picture untill 67hz, anything above will make the screen black. Running it at 67hz, the OSD says it's running at 1920x1080@120, despite that clearly not being the case.
5. The monitor supposedly only supports 144hz on the DVI port.
What do I do to run this monitor at its full potential? I've been having this dilemma for about a month already. Even tried using an HDMI cable for 40€, I don't think it did anything. Could it be that I need a better DVI to HDMI adapter?
