Do those DVD upconverters really work on HD TV's at improving the picture quality?

i just got those lord of the rings extended DVD's but they probably wont look like a bluray quality on my HDTV. however i went to walmart and saw they have these cheap $40 dvd upconverters that are supposed to make dvd's look near-HD. but does anyone know just how well these work? would it really improve the picture quality for a HDTV? has anyone here tried this out?


Answer
All these upconverting DVD players do is convert the 480p DVD video signal to 1080p before sending it to the TV, whereas typical progressive-scan DVD players send the 480p video signal (or 480i if component video cables are not used or if it's an older low-end DVD player) to the TV, which means the TV has to do the upscaling to whatever its native resolution is.

As a rule of thumb, it's always best to do any video processing, including upscaling, as close to the original video source as possible to avoid any signal degradation. But of course you can't create something out of nothing, so ultimately it's still a 480p video signal. Whether or not you actually see an improvement in picture quality depends on the size of the TV and the quality of your TV's video processor. Most of the time the improvement will be negligible, but it's just one less thing that the TV has to do.

How can I get the best possible picture quality on my LED HDTV?

I've recently purchased a 50" Sony Bravia 1080p 120Hz LED HDTV and while the picture quality of quite good straight out of the box, I'm sure it could be better. I haven't really altered the settings at all so does anyone know if there are particular settings to get the best possible picture? I do have it hooked up with a HDMI cable.


Answer
You cannot use anybody elses numbers because the adjustments are there to compensate for YOUR source devices, your cable and your particular television.

Go get a Pixar BluRay or DVD. In the disk setup menu you will find test patterns and instructions on setting your basic Brightness, Contrast and Color. This is important because televisions are set to nearly 100% brightness and contrast at the factory to be 'eye-catching' if the unit is used for a floor demo. Properly setting these values - will NOT look as good at first. But fine details will become noticeable, wide areas of solid colors will be more solid and not swirl with other colors, etc.

This is a basic calibration you are doing. You can always order the new Disney WOW disk, the Speiers and Munsel or good old Digital Video Essentials. These disks have more test patterns, are more involved but give you lots of great tutorials.

Start with a Pixar disk. This may be all you need.

Also - go into the TV and turn OFF various optional processing like 'motion flow' and other things. While these things do make motion smoother and make some details pop out - it can create un-natural effects like the 'soap-opera' effect. (Once you see this - you will know what I am talking about.)

Oh - and congratulations on the purchase.
