I have a little bit of an issue displaying the Raspberry Pi on a 1080x544 screen. The monitor is about 9" and has a HDMI input.

I have tried connecting it before startup, and it doesn't seem to work. The Pi defaults to 800x600 in that scenario.

Next, I edited the config.txt file and added this line at the bottom:

hdmi_cvt=1080 544 60

Now, i get a display that is shifted all the way to the left (imagine taking the image you should see,and doing a horizontal shift until almost everything is off the screen). When I change the refresh rate to 30, I can see more of the screen, about 20%.

The colors are way off (looks like some mix of inverted and blurred).

BUT, using my Windows 10 laptop, ubuntu 16.04 laptop or ubuntu 16.10 desktop, the monitor is recognized and works properly.

Does anyone have an idea of how to fix this or what may be wrong? I have a feeling that part of the problem may be the HDMI timing being off. Is there a way to get that information from the computers when they're connected to it?
