I have the Toshiba 42H83 (next year's model) working at 960x540p with
DVI:
Section "Monitor"
Identifier "Toshiba 42H83"
DisplaySize 93 52
HorizSync 31-46
VertRefresh 59-61
Mode "540p"
DotClock 40.86
HTimings 960 992 1144 1176
VTimings 540 551 557 568
Flags "+HSync" "+VSync"
EndMode
EndSection
The video card is a Chaintech SH5200-DVI.
Unfortunately, there is overscan that I am unable to correct. With
overscan, my effective resolution is decreased to 856x480+56+32.
I've tried the Audio Authority 9A60; that brought me up to about
952x504+0+20, but every time I switched the TV to that component
input, the convergence was completely reset and I'd have to fix it up
again. Upon switching away from those component inputs, I'd have to
again fix up the convergence.
The extra resolution was not worth the hassle of resetting the
convergence every time and having more parts to deal with, so I went
back to the DVI.
