Hello! Does anyone of you use the 49 inch Samsung C49RG94SSU Monitor with a MBP?

Every time I boot, the monitor is recognized differently:

It has 2 different names, although it is the same device. And as you can see, the maximum resolution supported also differs.

It depends on how I boot my macbook. When I boot it with the lid opened, the monitor is shown as CJG95 (top screenshot).

When I boot it with the lid closed, the monitor is shown as C49RG9x (bottom screenshot).

Another problem is, when the monitor gets recognized as C49RG9x, the MB scales its resolution to 5120x1440, but the monitor doesn't show any picture. It only shows the hdmi symbol in the top left corner for a few seconds, then it goes back to sleep and repeats.
