PC to HDMI input and Sony
M. Jameson says:
I received a Sony KDL-40VL160 TV for Xmas. The TV is equipped with 4 HDMi inputs, one designated for PC and a vga for PC.
I have a problem with HDMI/PC input. When switching from HDMi/PC to another HDMi input and then back, the TV says " No signal available". At which time I have to unplug the cable from the PC to the TV and then plug in back in, then it recaptures the signal.
I am using DVI->HDMi cable, Which is precisly what the HDMI/PC input is designed for. Called Sony, was told there is nothing I can do short of putting an A/V receiver in line between the two as it will repeat the signal, thereby correcting my Problem.
My Question is: Will an HMDi repeater or an HDMI video card (as opposed to DVI) accomplish the same goal?

Definitely related to a hardware sleep issue. Have you tried this potential workaround? Before switching away from your HTPC, put it to sleep explicitly, then switch over to TV - and then when switching back, switch back to the HTPC (expect to see the "no signal" dialog), but then a mouse or keyboard click to perform the wake up.
That may well work, as the explicit, user-controlled sleep and wakeup is designed to keep everything - OS, software, and hardware - synchronized for re-turn-on and operation.
Hope this helps, let me know.
EDIT and PS - There’s nothing magical about the HDMI/PC port other than it anticipates the common DVI->HDMI + independent_sound connections - same for VGA/sound inputs. The problem isn’t port-limited by the TV.
PPS - My suggested workaround is completely safe for your TV and PC hardware.
