I’m having difficulty determining whether my newly acquired Sony KDL-55W802A has the necessary PC capability/resolutions described here. The manual does list “HDMI PC Input” but I’m not sure if that qualifies it for this solution.
The listed PC video input signals are:
640 x 480, 31.5 kHz/60 Hz
800 x 600, 37.9 kHz/60 Hz
1024 x 768, 48.4 kHz/60 Hz
1280 x 768, 47.4 kHz/60 Hz and 47.8 kHz/60 Hz
1360 x 768, 47.7 kHz/60 Hz
1280 x 1024, 64.0 kHz/60 Hz (Full HD model only)
1920 x 1080, 67.5 kHz/60 Hz (Full HD model only)*
Currently, only 2x works, with default OSSC settings. 3x, 4x and 5x all supply audio but no video signal. 3x displays “Unsupported Signal” but 4x and 5x are just blank/cycling(unless I switch to TX Mode: DVI, then I get “Unsupported Signal”), which I thought may be a good sign.
I’ve attempted the solution in the OP with no success, but I’m unsure if I am missing part of the equation. For an SNES/Genesis to send 3x/4x/5x, does the Adv. timing need to be 960×240/1280×240/1536×240 respectively? Would they all require adjustment to 256 V. Active and V. backporch reduction? I’ve tried it in AND out of TX mode DVI/HDMI with no success.
Fundimentally, I guess I am just not quite understanding why the TV isn’t recognizing the 3x/4x/5x signals if all they’re doing is integer multiplying. If it can recognize a line doubled signal, shouldn’t any 1080p device be able to accept a line tripled/quadrupled/quintupled signal, as well? Is it just a matter of finding the correct Sampling/Timing configuration or is it a hardware issue?
I appreciate everyone’s efforts to broaden compatibility and educate the end-user. If you have any suggestions, I’d be happy to hear them.
