The difference between PC input (VGA) and video input (HDMI)

I'm not sure how many of you will understand what I am speaking about here, but I'll give it a shot anyway.

I used to have an Olevia LT32HVE LCD. When I would hook up an HD source to it , such as an Xbox 360, the differences between component and VGA would be profound. Eventually I found an HDMI model of the 360 and found that the differences were equally striking in sharpness when hooked up through the DVI port.

When hooked up through either the VGA or DVI port, it gave very sharp "PC" look to the picture. Through component I found it to look kind grainy, aliased, and not as appealing. I thought this might just be the set or the quality of the cables, but recently I have tried out HDMI on some other LCDs at the store and to my surprise, it looks very similar to the component.

I also have a Pioneer plasma which allows me to choose through DVI from the menu for the output to be PC (for the sharper computer-like picture I mentioned earlier) or video, which is technically supposed to be the correct setting for DVDs and video ouput, but gives the duller component/ HDMI picture I'm seeing on all these other sets.

Now I am looking for another LCD and I desperately want to get the PC-like look to the set while being connected through HDMI, however all the ones I try at the store are giving the look I got through component on the old Olevia/ setting to "video" on my Pioneer 507cmx.

For the record, I have not tried through VGA at the store to see if that did give the PC-like sharpness on some of these newer sets. However, I would really like to get this level of sharpness when connected through HDMI/DVI as I did on the Olevia.

Does anyone know what I am talking about? Is there an internal setting that can be switched to make the picture look like that sharp PC look which made it look almost identical to looking at a PC monitor? I'm fairly sure it's a setting within the TV as my Pioneer has showed I can switch between the two when I am connected through DVI/HDMI. I could not find a similar setting on the TVs at the store though.

Thank you so much. These were exactly the models I was interested in too. I can't wait to check it out.

For clarification, can you let me know where this setting is in the menu? Is it under picture settings?

Do you use this setting? Do you know about the PC-like clarity I was speaking of?

I'm not sure if your'e quite understanding what I'm talking about.

I actually did try out a 71 series at the store yesterday with an Xbox 360. Even set to 1080p on a native 1080p set, I wasn't getting that PC sharpness I was looking for. i did get that PC sharpness through HDMI on my other 1366x768 sets though when set to PC mode (Or in the Olevias case, this was the default when using VGA or DVI).

It didn't really have anything to do with me preferring VGA over HDMI/DVI or anything like that. Especially since I know HDMI/DVI is capable of doing the PC look I'm speaking of. I just couldnt get it going on any of the newer sets. it looked more similar to component than PC if that makes any sense.

I will try it out now that I know about this PC mode through HDMI. I am anxious to see if it works as it sounded like the other guy understood what I was speaking of.
