thanx, mike, i'd forgotten that majick incantation;-)
state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

Group CEA has 9 modes:
mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive
mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive
mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive
mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive
mode 5: 1920x1080 @ 60Hz 16:9, clock:74MHz interlaced
mode 6: 720x480 @ 60Hz 4:3, clock:27MHz x2 interlaced
mode 7: 720x480 @ 60Hz 16:9, clock:27MHz x2 interlaced
(native) mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive
mode 32: 1920x1080 @ 24Hz 16:9, clock:74MHz progressive
so i've set mine to
hdmi_group=1
hdmi_mode=16
and to get the desktop onscreen, i've set
overscan_left=145
overscan_right=145
overscan_top=60
overscan_bottom=60
btw, it seems
YScanDisplacement | 60
XScanDisplacement | 145
do nothing (and the gui only allows values<=50, which also do nothing)
and no matter what negative value entered
VertScanPercentage | -6
HorizScanPercentage | -6
the video is reduced ~40%...oh well, at least i can see the whole image;-\
