BACKGROUND: I have a Sony VPLHS51 and a Denon AVR-3806 A/V Receiver that I use for audio/video switching (among other things). I have a component video connection to the PJ and it appears I may be forced to add an HDMI connection. I say forced because if I want to use the HDMI In/out switching function, I get no Component output b/c Denon does not convert HDMI input to Component output (I assume this is a copy protection restriction if nothing else).
My problem is that I want to be able to incorporate my laptop (or perhaps a dedicated HTPC) to the A/V Switching. I figured I could do this with a DB-15 VGA to Component video adapter/cable. I have tried many different Computer video setting, but get "Frequency out of Range" on the Sony VPLHS51 for everything I have tried with the VGA to Component cable. When I look at the 'information' on the Sony PJ menu, it shows Horizontal and Vertical frequency both set to 999.9 (or was it 99.9) - my assumption is that these FRQs are not set to any value by the PC, and I can't find a place to set them. The monitor frequency setting in the PC setup is 60hz, and trying other hz numbers (66, 72, etc.) makes no difference.
QUESTION: Has anyone successfully tried to connect VGA out to Component in on the VPLHS51 (or another projector for that matter)?
Alternative 1: I suppose I can run a DB15 to the projector, but since I have component already and will run HDMI next, I think the 1-1/2 conduit in the ceiling to get to my projector will start to give me space problems with all three cables, especially for pulling through the DB-15 connector. This also complicates the video switching, since it is no longer done via the Denon A/V receiver. Some of this could be alleviated by just leaving the Sony PJ on auto source selection, but the VGA Video would probably be on a lot of the time.
Aside note on long VGA/DB-15: I have not seen good results with long VGA connections; the 25' shielded video cable I have has serious degradation of picture quality (sparkles, etc.) when compared to a cheap 6' unshielded cable. Not sure if this is a general VGA problem, or with the specific cable I have. A Crutchfield showroom salesman said when he ran long VGA connections for a University, they ran multiple shielded RG-6 coax with a conversion to VGA (presumably soldered) on each end. Seems to make sense it would work, but pretty bulky.
Alternative 2: if/when I get a dedicated HTPC, I could ensure I have a DVI output and convert the DVI to HDMI via adapter/cable. Should I expect to run into the same frequency problem with this scenario? Anyone tried this?
