Thanks for the suggestion I tried it but with no luck.

I did some more digging and I think this looks correct from my X log:
(II) NVIDIA(0): Computing DPI using physical size from SHARP HDMI (DFP-0)'s
(II) NVIDIA(0):     EDID and first mode to be programmed on SHARP HDMI
(II) NVIDIA(0):     (DFP-0):
(II) NVIDIA(0):   width  : 1920 pixels  820  mm (DPI: 59)
(II) NVIDIA(0):   height : 1080 pixels  460  mm (DPI: 59)
(--) NVIDIA(0): DPI set to (59, 59); computed from "UseEdidDpi" X config

Later I was able to change the DPI to 100x100 but it didn't help and as I
understand it 59x59 should be ok since any square pixel with a 16:9
display size should be recognized as yielding a 16:9 display correct?

I found out the NVIDIA drivers now ignore the display size option but the
detected display size from edid is 820x460 which is also ~16x9 (1.782 vs

I'm at a loss if anyone could help I would be very grateful.
