So I got a 73831 the other week that displayed no picture. Took out the optical engine and cleaned up lenses, color wheel had all sorts of gunk on it, threw in a new Phillips lamp and BAM good to go!
So I am hooking my computer up directly from a DVI port to DVI on the TV with a DVI-I single link cable.
I have a strange issue. I realize that true unaltered 1920x1080@60Hz (at least, according to the user manual) is going to have all sides slightly off the screen (I could use reduce format, but I wants crispness!!)- but OCCASIONALLY if I switch between resolutions, I get yellow text at the bottom of the screen stating:
Invalid signal type. If analog PC, change setting in Input Name Menu.
Once this happens, if I switch back to 1920@1080@60Hz, it no longer appears correctly. In standard format the output from my computer to the screen is no longer 'too big' for the screen and there is a strange flickering. This can only be resolved by rebooting my computer, or switching to 24Hz and then back to 60Hz sometimes resolves it.
Is this a known issue?
Does anyone have EXACT information beyond what I have been able to find in the manuals for what this TV really likes over its DVI connection?
Scan type: Progressive or Interlaced?
Timing: GTF, DMT, CVT, CVT reduced, or a totally custom one?
If totally custom, what should the horizontal and vertical front porch and sync width be at 1920x1080? Is the polarity positive regardless?
Any help would be very appreciated
