Moving Picture Resolution - Is 1080p really 1080p?

Probably a little OT from this thread but what are the exact settings used for that? Can this also be done for 480p/24?

You mean besides the annoying blank (or wavy white/grey/black line) screen as your TV resyncs to the new resolution

Depending on how good the video processor is in your TV/AVR you may get better results using a PC for scaling and DI.

I'm pretty sure you can define that (or maybe 480p48). But I'll throw one thing out most "480" content is 480i60. DVDs are 480p24 telecined into a 480i60 container. So from that perspective, I think you'd be better off outputting 480i60 (native) than having the HD200 try to deinterlace it to 480p24.

Well, yeah

Not my (retired) HTPC

Yea, I had native output switching set and had 480i/p set as possible resolutions. My only problem with that was that I'd actually lose horizontal resolution of 480i/p 4:3 content. Because SageTV is set for the display to be 16:9 that is what is sent to the TV over HDMI. The HD200 then scales the 4:3 to fit on a 16:9 screen. The way I finally figured out what was going on was that I noticed the menu was stretching all the way across the screen rather than fitting into the 4:3 of the video.

But besides that, do you just specify 1080p24 as one of the possible resolutions in the config file?

Yup, the extender_extra_resolutions property, or whatever it is, I'm sure I posted it at one time.

Interesting. I'll have to try that out some time soon and see if my TV will accept it.

Might be easier to have it auto-switch, but I have no problem just manually switching my PC output between 1080p/60 and 1080p/24 with the touch of a button on my remote. Plus, I can have blu-ray menus... if the HD200 (or 300) ever gets full blu-ray support (including HD Audio), I'll probably get one, but until then, this is working JUST fine...

And actually, you can set ReClock to automatically switch your PC output as well, though I've had problems with it's detection on some ATSC broadcasts that are poorly flagged (cycling FILM/Progressive)... though this is really a source problem.

I had that setup, but it would cause PowerDVD to black until I restarted it.

For that reason resolution of a TV is somewhat of a complicated issue to begin with because there is no pixel for pixel mapping to a TV LCD as there is for a computer monitor.

As Stanger said, a lot of it has to do with the image processing capabilities of the TV.

Nah, only crappy LCD and Plasma's use a triangular pixel mask... good 'ol DLP's don't have such a thing... a pixel's a pixel.. ;-)

And if you have a really good projector, you can get the red, green, and blue parts of a pixel focused on the exact same spot in your screen, and "white" is actually white, and not red next to green next to blue, and "Red" is not red with two small spaces of black next to it, and so on This can really help if you have a large screen or sit really close. Single chip DLP projectors also have it a little easier in that the sperate colors are flashed sequentially really fast and your eye interprets this as a single color, unless you are subject the the "rainbows" that some people can see.

I actually really like the crossover that the checkerboard DLP's have, eliminating any sort of screen door (each pixel is shown on the screen slightly larger than the space it occupies)... Unfortunately, the market is moving away from quality and going with the form factor advantage of the flat panel screens.

[Taddeusz]

Probably because most people can't tell the difference or don't care because of the form factor. Like it or not most people want a nice thin LCD hanging on the wall rather than a projection tv plus furniture that takes up a significant amount of floor space.

Good DLPs don't do that

True, but even 'crappy' DLP's do that..., and GOOD DLP's don't even need to. My point being, DLP will always present a better quality picture than an LCD or plasma costing twice as much. LED DLP's really were the pinnacle of TV picture quality... quality has dropped in favor of form factor for the last 3 years.

[stanger89]

I don't know, I've never been a fan of rear projection, never seen one I really liked, that I can recall. I avoided LCDs for a long time because I didn't think they looked good, but I'm quite happy with the one I've got for my living room now.

Of course I've got a 1080p DLP in my HT, but when you start comparing very large front projection to comparatively very small LCD/Plasma/RP, it gets very complicated comparing "better".

[panteragstk]

I can't wait to get my projector. It is a single chip DLP. I just hope the wife doesn't see any RBE.

[stanger89]

I've had a lot of friends over viewing mine, and no one's ever complained/commented about it.

I don't expect her to, but it is a possibility. She's never noticed it on any of my friends' dlp tv's.

Then if she doesn't already know about this possibility, I would suggest you don't bring it up to her - that's a sure fire way to get her to notice it.

No kidding. That is why I can't watch LCD tv's. I see the screen door effect waaayy to much (yes this includes 120hz and 240hz tv's). I sold quite a few plasma's back in the day by pointing it out to people. You can't unsee rainbows or SDE. I try to ignore SDE when I'm over at a friend's, but it just makes my eyes hurt so much. If I'm far enough away I can't see it (thank god).

My wife doesn't notice any of the negative picture quality stuff I ask her about. She looks at me like I'm crazy every time I ask her "did you see that?" That's what I get for being an A/V salesman. I wasn't picky at all before that. One of the best jobs I ever had though...
