How do "uprezed" DVDs look compared to HDMI DVD Players?

I'm wondering how uprezed DVDs on a Blu-ray player will look compared to DVDs played on a HDMI DVD player or the DVD player of a HD TV. Is the answer, "Not widly different by any margin?", and could someone post comparison shots?

Do you mean upscaled DVDs in a Bluray player compared to upscaled DVDs in a DVD player? It would also depend on what other hardware is involved. You TV would also be upscaling, and if you're going through an AV Amp, that might be doing something too. Basically, it's an impossible question to answer, and certainly not something that anyone could show you definitive screenshot evidence of.

Exactly. If you use any kind of pixel-based TV (so, LCD, "LED", OLED, Plasma, etc...) then some upscaling will be happening. Has to be.

The trick is
a) to only upscale once. If you can set your TV to do 1:1 pixel mapping then upscaling in the player - whatever kind it is - is good. If you can't, it's not. Better then to allow the player to send out the signal native to the disc and let the TV do the scaling
b) if you have a choice, use the thing that makes the best job of scaling; that may be the TV, or it may be the player. Or an amp if that's in there, too.
c) turn off (or to their "null" settings) any sharpness enhancements, noise reducers, and other things that process the image. They all degrade, really.

Well, the hardware I'm talking about is...
-The DVD player in a Technika TV.
-A HDMI DVD player like Toshiba or Denver's
-Any Blu-ray player, including the one in a PS3.

If you buy a decent Blu-ray player like a Panasonic DMP-BDT230 or an equivalent player from Sony and the likes, then I would expect that player to do a better job of upscaling DVD content than your TV (which is what would be doing the upscaling from your DVD player). It all depends on how good your TV is though.

Basically it's either your Blu-ray player that upscales to 1080p or it's your TV, DVD players don't do 1080p output.

Then why do they have HDMI ports?

HDMI DVD players typically DO upscale to 1080p if so set. There will be no material difference between the upscaled output from a half-decent upscaling HDMI DVD player, and from a half-decent BluRay player playing a DVD, all other things being equal.

In reality you will be unlikely to notice any material difference between all of the methods of filling your screen - as long as there is only one scaling process occurring in the chain and all other things being set equally.

Examples of excessive and avoidable PQ deterioriation include:

- player set to upscale to 1080p and TV is set to overscan (meaning, it upscales a bit more). If you want overscanning (and it IS useful on SD sources to crop off garbage) then ensure the player isn't upscaling at all; leave it to the TV to do it all at once.
- player set to upscale to 720p; TV is a 1080p screen so upscales again
- noise reduction = on
- sharpness enhancement = on
etc...

How to go about achieving this is troublesome to describe as each manufacturer uses different terminology. On my Toshiba TV for example, no scaling is called "Native".

Maybe both! The last time I bought a DVD player was probably 10yrs back though!

The OP could try one of those setup modes on dvd discs like Star Wars, or burn various resolution test JPGs on a dvd (assuming the player can play a JPG slideshow).

Without wishing to appear snobbish, if the TV you're outputting to is a Technika one with a built-in DVD player, I suspect all options would look pretty grim.

All options meaning everything to do with the built-in DVD player or all options for DVD to TV?

Technika is not what most would consider a "good" brand, although I have no doubt it works.

I doubt hugely you will detect much difference between playing a DVD on the onboard player, and playing a DVD using an extrernal, upscaling, player (BluRay or DVD) via HDMI

But I have to say again - all other things being equal. Different settings (for picture "enhancement" tweaks and so on) will have a far more marked effect than different sources.

Also no matter how good scaling is, you're only ever going to see DVD quality. So if you want to get the best out of it you need decent kit.
