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;-\
