Hi Mark: Thanks for that. I don't know how far down the line you are
at present, but my most recent builds have had 'Appearance' problems.
I'm currently at 27188d. I can send more details if you like.
The fonts are too wide, so text is often incomplete
Aspect ratio: the picture is half-height, centred. The only likely
option, 'Virtual monitor aspect ratio', seems to be doing nothing on
either screen. Default settings are still as above. The 'Display on
screen' option has not been effective.
... and the NVDEC detection on first startup is still unreliable. It
seems to need shaking in.
HTH, HNY etc.
John.
