You have to qualify the difference between a "PC" whose Video Card does not have HDMI but only VGA , and one that has both, and you want to determine which might be best. (...Your previous post did that somewhat....) As for PJs, they have to themselves support higher resolutions, or something has to give.
So, the Display. You would seem to me to be asking how a PJ would perform, not a Current model CRT/LCD/ Display on a PC system or a Laptop serving up video only through a VGA output. The OQO units (...you have a Model 2 most likely) have VGA/DVI/HDMI outs so the V card obviously supports all those. Your right about the cord itself to a point. VGA can pass through higher resolutions IF they are available...but it won't support 1080p You now have a 1080p PJ
. It does not support any higher resolution than 1080i/p. In that respect the resolution coming through VGA in excess of 1920 x 1080i is moot.
Besides that, VGA output first off does not itself support HDCP, and as such when such a high resolution input is brought into a PJ that has a HDMI in (specifically the 1080p LG CF181D here but to include any 720p PJs as well...) via VGA, the signal received is not going to be processed optimally compared to a true 1920x1080i or p signal. The higher the Resolution, the more it will be compressed, IF the display even has the ability to accept and process it at all..
The LG supports resolution up to 1920x1080 i/p. The other resolutions may not display properly...if at all. All you can do is try, but the inputted signal will be at a disadvantage...not have any advantage.
My answer was predicated on the output coming from a PC card w/no support for HDMI. My experience with using VGA has always been that of seeing 1080i resolution being the highest supporting Res. level available in those cases, and that being dependent upon the PJ. 720p PJs still have to compress 1080i signals.
Basically, if your inputting a 1080p signal, the display has to support that entirely, or itself compress it down (...many 720p PJs can accept and compress 1080p...)
Ditto with any higher interlaced resolution.
The answer to your question, taken into account the disclosed qualifiers, would be that you will not see those higher resolutions displayed on the LG in their native resolution, if at all. If they are viewable, they almost assuredly will not show an improved image, they would be lucky (...as would you...) to see a comparable image.
I'll venture to say I myself did not really qualify my own comments with enough info, (...or enough deep knowledge of the correct vernacular...) but I'm not trying to be, nor can claim proficiency in all things "PC" oriented. I do know that none of the VGA out only Cards I've had supported resolutions beyond what I stated.(1488 x 1200 actually) Your OQO and it's Video processing is obviously a different animal altogether. (...a small one, but mighty in premise...)
