Ugh.
SpotTheCat wrote:It's worse than that. Though you can easily bring a set out of "torch" mode, things like inaccurate colors can't be adjusted on the majority of sets, even in the service menu.I've read a lot about what Vrock saying to be true about out-of-box settings. They tune these things to look good next to their neighbors in a store isle under fluorescent lighting. A lot of the better ones have good home-use profiles already in them, but others you need to tune yourself when you bring it home. Apparently the settings are extremely stressful on the hardware, too.

So for me that eliminates all the "thick" technologies at any sort of large size.
UberGerbil wrote:Those are good points, I think. Now there 37" 768p plasmas and 42" 1080p plasmas on the market though, and prices favor plasmas vs. LCDs. I can't think of many reasons these days why a consumer should pick an LCD over a plasma for HDTV purposes.LCDs got so popular because plasmas did have a bad rep for lifespan in the early days, and like a lot of other things in tech the received wisdom doesn't always keep up with developments. LCDs were available in smaller sizes, so plasmas were out of a lot people's budgets until relatively recently. And LCDs went 1080 first, so they could claim that advantage as well. The backlight and black levels is a an issue, but many consumers are looking at them in the bright lights of a superstore not in the darkened ambience of specialty AV store. I think this also is why they always arrive from the factory with the brightness turned all the way up.

Vrock wrote:The contrast is definitely one of the factors, as is the color. I'm also a big fan of the viewing angle on plasmas, as you're not always able to sit directly in front of the set. We have a sofa directly in front of our set with a love seat to the left and perpendicular of the sofa. If my wife decides to hog the sofa, I can still sit on the loveseat (or the recliner on the other side of the room) and still enjoy a great looking picture. Brightness isn't that big of a factor for me. My set is only 5000:1, and it's more than adequate for my viewing needs regardless if the living room is very bright or dark. The image has just the right amount of "pop", and I couldn't be happier. Though I am pissed with Cox (my cable company) at the moment. They recently did something (possibly an upgrade to the STB) that makes the reds on my set bleed. A lot. At first I freaked out and thought it was my set. But after playing with the settings in every conceivable way, the reds still liked to bleed. I was unable to replicate the issue with both my Wii, Xbox 360, and my upscaling DVD player. So I called Cox and they said that I'm not the first person to complain about it, and that they're "working on it". Bastards.In your opinion, what is it about the plasmas that makes them look better? Color? Contrast? Overall brightness? For me it's definitely the contrast.

My friend has a 56" RP that makes it almost unwatchable if you aren't sitting down on the couch or the chairs, while mine it doesn't make much of a difference as long as you are abour 4' away.

This varies from parts from some stuff being standard def, to some motion artifacts... blockiness, smear, tearing, stutters, to the whole picture "graining" out or "blocking out". Interlacing/deinterlacing success and motion problems. Due to these problems, you may wear yourself out going through setup screens enabling/disabling Processing your TV does.

If you get a picture with some fine grain detail and near still or little motion, and watch it, the stuff appears "crawling" even though it shouldn't be.
cass wrote:Standard def is fugly on all fixed pixel displays because of scaling. Another reason to miss CRTs.I got to play with some type large sony rptv this summer in a house we rented, and it had a very nice picture. I don't know the model or what the technology was, but it looked like a nice alternative for its rather large size.
standard def was fugly on it, but what hd source I had and could find was beautiful.

They don't help a whit with motion blur because they're (sadly) still 8ms panels (albeit 10 bit ones).Has anybody done a side-by-side comparison of the 120Hz LCDs with the 60Hz ones? The ones that actually do motion prediction and interpolation should help with motion blur.
Vrock wrote:That's interesting (and unfortunate). They're 10bpc? Do they claim support for "deep color" (not that I know of a consumer source for that).I've demoed one of those LCDs in my house. They don't help a whit with motion blur because they're (sadly) still 8ms panels (albeit 10 bit ones).
Yeah, I always thought they should've started at 120Hz, seeing as how it was a convenient multiple of film and video frame rates (well, close enough) and would've simplified the whole chain. I guess the tech wasn't available at the time (at least, not at a sane price).The blur isn't from the source framerate it's from the display refresh rate. The interpolation and prediction algorithims (Sony calls theirs "motionflow") can do a nice job at smoothing out judder, though, and the 120hz does get rid of 3:2 pulldown once and for all, so it has its uses.
Well, of course the problem is that it has to guess and sometimes it guesses wrong. There's potential for adding additional "hints" in the stream to aid in that, but it's going to depend on the algorithm the screen is using. You could imagine Sony adding hints to Sony Pictures BR streams that only help its screens.My SXRD has motionflow and I leave it off...it can make things look a little artificial and introduces artifacts of its own (you can detect when it "locks" onto a frame and starts interpolating). I do let the 120hz do the 5:5 for Blu-ray, though.

UberGerbil wrote:The two modes that Sony offers are a Standard and a High mode. Standard can really smooth things out and they look pretty natural with the occasional visible artifact. It's pretty decent, really. High on the other hand is an absolute joke. It makes everything look like a video game, it's so uncannily smooth in such a bad way. It's hard to describe, you have to see it yourself.Well, of course the problem is that it has to guess and sometimes it guesses wrong.

SpotTheCat wrote:I would think it wouldn't, at least not in the near term. I'm pretty sure that Sony is required by law to maintain stocks of service parts and the like for several years after phasing out a product, plus it's just good business. The aftermarket supply might dry up but I'd bet Sony will still have bulbs. Heck, Pioneer still has parts you can order for some of its laserdisc players made back in the 90s.I wonder how this will change the price of replacement bulbs, if at all.
Vrock wrote:You know what those 52" LCDs are good for? People who care more about how a television looks than how it looks, if you get me. Style over substance. If you're going to go flat panel, do yourself a favor and get a plasma. Even the best LCDs aren't as good as a decent plasma; especially when it comes to temporal resolution and black levels. Then there's backlight leakage, poor viewing angles, and backlight banding, all of which can ruin watching a TV in a darkened room. Frankly I'm amazed that LCDs are as popular as they are when plasmas are cheaper; it shows that the average consumer either doesn't know or doesn't care about image quality.

you have clearly never seen sony's bravia XBR series. the viewing angle is 178 degrees and the color and picture quality are amazing.
leor wrote:Where did you get this info? 1080p plasmas are in fact 1920x1080.also the main benefit for LCD screens over plasma is pixel perfect resolution, and computer compatibility. a plasma @1080p uses some odd resolution, where an LCD uses actual 1920x1080. it's very sweet for my HTPC setup.

You are a very discerning user. That bit hasn't been said much around here.
