Is there ANY quality loss whatsoever if I'm using an HDMI to DVI adapter?

How about a DVI to HDMI, if I wanted to plug in my PC to an HDMI/component only television? (Namely, the Panasonic TC-26LX600)

I'm already looking for alternatives to my Sceptre 22wrg monitor, that will support a direct hookup from a PS3 via HDMI, and a hookup from a computer DVI to HDMI, or if need be, DVI/VGA to component connection (which I have the adapter for, but I know there's always a massive loss in connection whenever going from an analog to digital signal).

The TV has 2 HDMI inputs, a component input, 2 S-Video and 3 composite.

Thanks.

:edit: This may be braindead, but the TV's resolution is 1366 x 768, however supports 1080i. Am I limited to only 1366x768 if hooked up to a PC via DVI to HDMI?
 
HDMI and DVI are exactly the same thing, except DVI doesn't transfer audio. You can easily buy a HDMI-DVI cable.

You will need to go with 1366x768, since your video card will output a progressive signal and not an interlaced signal(which is really bad compared to progressive, unreadable text...)

But you are better off with a real computer monitor, since if your tv doesn't receive a "valid" signal(means a resolution it support) it wont show anything at all. Unlike a computer monitor, a LCD will show any resolution, except it wont be as good as the native resolution
 
I have my vid card connected to my sony tv using a DVI to HDMI adapter, and i can get 720p and 1080i, it works normal, but i have to use 720p becouse 1080i the image lags a little.

No, however, if you want to run the TV in native res then yes. I run mine at 1366x768 and it looks great. I can give it higher resolutions, but it does not look as good.

Even if I tried to pull off a 1920x1080 resolution through the computer?

You could pull that resolution, but from my experience it wont look as good as running native. Many tvs will accept a much higher resolution but it wont accuratley display that resolution.

from what you've said the monitor doesn't support it, so no

Monitor might take it, but not display it accurately.
 
I dont think its becouse of the P, but looks more like my PC cant handle the pressure, becouse my DVD Player upconvert and it works OK

your video card might not be good enough, but i run an old 9600Pro at 1920*1200 and dont have a problem watching movies. P stands for progressive, all computer monitors and video card are progressive because the image quality is better, sharper, text a clear and readable. When looking in my Catalyst Drivers, i realized i could also display 1080i for a HDTV, so apparently yes you can do it, but like i said, the text will be really tough to read, so not really good for computer use...

I have a 7900 GTX with a Core Duo2 E6700, I'm using 720p now, becouse I really cant tell the difference, and my sony TV only accpets 1080i, but when I set the tv to 1080i the image feels slow, and some times the image comes in ripples, maybe i have something set wrong.
 
As far as I know TVs that have a 1366x768 native res are just downscaling 1080i signals. You need a 1080p TV to display a true native 1920x1080 signal.

A/V gurus feel free to correct me if I've got any of that wrong.
 
I have a hdtv that supports 1080i (1080p through component for some reason but not HDMI? lol) and I have a media PC. Now I just recently found out that my media rig can't handle 720p let alone 1080p, it'll lag and crash like a bitch and when it does play, its choppy and plays like crap...but it looks great in the scenes I can see! :D

AMD Athlon 64 3200+ Newcastle 2.2ghz
1GB Supertalent DDR PC3200
6600GT AGP 128mb

Thats the quick and dirty specs...

Now when I plug my main rig into the tv and try the same HD trailer...it runs great, especially @ 1080p. Maybe I should get a dual core proc for my media center because I think I'm severely CPU bottlenecked.
 
my 9600pro and *cough*2.4 celery*cough* handles nicely the 720p, but 1080p is a bit choppy...

Your processor i believe is good enough, but the gpu isn't probably...
