Friends, I've searched high and low for a solution, nay, a mere reference, to my current problem, and I have come up short. I appeal to the experts for guidance.
I just got a Sharp Aquos LC-42LE540U, and I'm using it primarily as a display for my PS3. Everything looked fine and dandy in 1080p, games and movies and whathaveyou, but currently I have a single game (Journey, if anyone's interested) that causes the TV to switch to a 720p mode, and it's squished at a 4:3 aspect ratio.
"View Mode" only offers me the options "Normal" (which is squished) and "Dot by Dot" (which displays the proper aspect ratio, but of course at 720 pixels tall in the center of the screen--massive black border on all sides), and I cannot figure out why I would be missing all of the various Stretch modes that would immediately fix the issue.
A bit of additional info: In order to combat the pronounced input lag that destroys the ability to play games, the TV's HDMI properties had to be set at "Graphic" as opposed to "Video." I believe that this "Graphic" mode is limiting the View Mode options, and removing the opportunity to stretch that 720p over the whole screen. I can, of course, change the setting to "Video," and it does indeed display in the correct aspect ratio and full size, but the lag is unforgivable (by my timecode photo tests, the display lag jumps from about 2/30 of a second in "Graphic" mode all the way to 6/30 of a second in "Video").
Since the TV does display the picture correctly in "Video" mode, I've all but pinpointed the TV as the source of my issue. The PS3 is set up to output 1080p and 720p, as well as 480(or whatever SD is) as a last resort. This particular game, as my research has indicated, is strictly 720p, so when the PS3 outputs 720p it is doing its job correctly. (And as a test, in the ps3 settings limiting the HDMI output to 1080p, starting the game results in a 480(or whatever) staticky and fuzzy image).
My ultimate question is: has anyone else has experienced this, or figured out a workaround? I'm wondering if there's just some option or trick that I'm missing (considering how the Input Terminal Setting>HDMI option that fixed my lag problem eluded me for as long as it did).
Having futzed with this for a while now, it looks like maybe this just isn't the HDTV for gaming output...
