Thanks. Well, I went out and bought a 48" inch 4K TV to use as monitor but had to return it because the color loss was terrible and it was much bigger and heavier then the Philips. I thought that 8" inch more wouldn't be that much bigger but it does feel so. The Philips screen is really not so big on the desk as I thought and it really feels light and is easy to carry. It's even ok to use with the stand, it wasn't too high for me so I will probably use the stand on the new monitor.
The upper edge of Philips does not feel too high? First guess is you belong to those higher ones This would mean there is a couple of inches reserve in size for you. My feeling is though the 40" is about the maximum and 48" is definitely too high. For you 42" could be still acceptable.
