Default Is the quality of HDMI for all players the same? (lcd tv dvd)


Just bought the LG DV9800H dvd-player with HDMI-out. Even on the highest
resolution (1080i) the picture on my (rather expensive) Philips 32PF9830
lcd-tv is no better then with an ****og RGB connexion. Even the
starting-screen with the "LG" logo looks blurry. Playing ""Apocalyps Now",
redox version, the (dutch) subtitles look awfull. Is this because it is a
rather cheap player or doesn't it get any better, even with an expensive
player? (connexion is a 2m (Thomson) HDMI-cable, bought for ? 45,-). Please
respond!

It won't be. All DVDs are fixed at a far lower resolution than even
720p high-definition material. This is a restriction of the DVD format
itself, not the player. What the DVD player will do is 'upscale' the
picture to a higher resolution before sending it to the TV. Almost
without fail, this will look *lower* quality than just sending the TV
the footage as it appears on the disc and allowing it to do the
upscaling itself, especially in the case of a cheap DVD player connected
to an expensive TV.

There is absolutely no advantage to having HDMI-out on a standard DVD
player - except, possibly, where you have nothing but an HDMI-in spare
on your TV or projector.

Why what? Why will it look lower quality? Because if, as the OP, you
have a 'cheap' DVD player connected to an 'expensive' TV the upscalers
in the TV will be correspondingly more 'expensive' and thus give you a
higher quality.

Of course, there is always the possibility that the 'expensive' TV was a
rebranded ripoff, in which case the DVD player will give you higher quality.

Either way, to expect a massive (or, in my experience, any) improvement
over standard RGB is to court disappointment. If you want a
high-definition picture on your high-definition TV, you will have to
wait for a high-definition playback format (HD-DVD or BR, depending on
which wins the battle).

What you say makes sens, that the expensive TV (37PF9830 in my case) has
a better scaling than cheaper DVD-s. How about Marantz DV-6600(HDMI-out,
video scaling 1080i)? It is a 500$ class. In the store, where I wonted
to buy Pioneer DV-585, went totally crazy on me when I told them witch
TV I was going to put it on, saying that it is nonsense to put 200$ dvd
on that TV. Personally all I want from a DVD player is to play every DVD
that I put in it, and have picture that i can say is good. Its not like
I want HiFi video vise quality.

[This followup was posted to rec.video.dvd.players and a copy was sent
to the cited author.]

In article <dnctkt$e84$1@news2.zwoll1.ov.home.nl>, jos.adriani@home.nl
says...

DVD's are 720x480NTSC/720x576PAL. Upscaling means it has to
interpolate and create extra pixels based on nearby pixels.

Also, the native resolution of your TV is 1366x768. If you upconvert
480 to 1080, the TV then DOWNCONVERTS it to 768 for display. When
downconverting, it merges pixels together. So now you have fake pixels
being merged with inerpolated pixels and mixed up with original pixels.
The result is a major mess.

You could try using 720p instead of 1080i to see if it improves.
Otherwise, stick with the standard 480i or 480p. The upscaling on many
DVD players is not that great. You can only get so much blood from a
stone.

No - any SD (Standard Definition) picture upscaled to HD (High
Definition) will look poorer than if it had been left alone. Buy a $40
player with RGB and/or component output and let the TV handle it - after
all, that's why you bought an expensive TV in the first place. Who
would know how best to make the picture look good on your TV: a
third-party company who have never *seen* the TV, or the people who made
the TV in the first place?

Remember that salesmen in shops are not your friends - of *course* he's
going to express shock that you didn't buy a $500 DVD player; you're not
giving him as much commission if you 'only' spend $200. I'll bet he
told you that you 'needed' $300 oxygen-free-copper unidirectional
gold-plated cables, too?

It has come to my attention that only digital signals can be upscale by TV,
so you wore only partial writhe. HDMI or DVI connections will look much
bather than component, but there is no need to buy player that has upscale,
rather let the TV do it itself.

Default Is the quality of HDMI for all players the same? (philips)


According the the manual available on the Philips UK website[1] the
component input will accept (and up/downscale) SD and both flavours of
HD without a problem; thus my original advice remains: buy a $40 DVD
player with component (*NOT HDMI*) output for best quality. Save the
HDMI input on the TV for when you get a true high-definition device such
as a HD-DVD player.

Gareth, you seem to have a lot to learn about quality dvd players...cos you
cant buy one for $40.
