72 I'm still using the SVGA port, not the HDMI port
73 and I do experience a little bit of "cropping"
74 but the numver 1360 is more correct. Everything
75 my setup is pretty much standard.
76
77 The model number was indicates a 32" screen, but
78 in fact it is a 37" screen. I do not believe this
79 makes a whole lot of difference. If/when you get
80 the HDMI interface working send me some email
81 with any differences in the xorg.conf file you notice.
