hooking up a plasma to a 8800gts 320 mb

[alanwest09872]

ok i just bought a hit 42hdf39 plasma (42 inch)
I have a 8800gts 320mb graphics card and a 22 inch lcd

I want to run a clone display on the 22 inch i want to run 1680*1050 and on the plasma i want to run 1280*1024 resolution.

also under the nvidia control panel under the "option change the signal or hd format" only the gateway monitor is displayed not the plasma. (the plasma is on almost every other option except that one) and when i select that option it only goes up to 780p not 1080I

i want to be able to select the plasma tv and the 1080i option. so that way i can play

HD is either 1280x720 (720p/i) or 1920x1080 (1080p/i). So you cant run your plasma at 1280x1024... I recommend you run it in 1280x720... Are you sure it is even 1080 capable?

And besides all that... how do you expect to CLONE the image in different resolutions? if they are not exactly the same it is not a clone. It is just two monitors.


EDIT: WTF, I looked it up and it says its a 1024x1024 display with 16:9 ratio and ability to "processes" signals up to 1080i. This makes absolutely no fucking sense.... the 1024x1024 resolution doesn't exist, and is a 1:1 ratio not 16:9.... and "ability to process" usually means "downscales". Something is definitely wrong there.

The pixels on some plasma TV's arent square so the 1024x1024 is correct for that TV

thats... thats fucked up beyond belief...

Anyways the absolute BEST way to plug an HDTV to your computer is by having an HD Capable card (like you have) and using the dongle to plug into the HD port (that little black circle that LOOKS like an S-video port with extra pins) and then split into the three color component video.
Just set it to output 1080i over component and you will be good.

i bought a dvi to hdmi cord and it made everything perfect i have it running at 1080i and it looks beutiful.

1920*1080

walmart special 799

hitachi also cant beat that

DVI to HDMI causes significant quality degredation. DVI to HDMI is meant for a few rare HDDVD decks that came out with HDMI output but a DVI plug... conecting a computer through one of those cables does NOT work properly and causes you to have vastly reduced resultion. I researched the heck out of the subject and actually tried all the solutions. Trust me on that one, try the HD out with component output. It will look way better then DVI to HDMI cable. (they make DVI to HDMI conversion boxes that actually convert the signal, but those START at 200$)

you are completely wrong on thi sone.


dvi to hdmi works on pretty much every tv. the main problem you get is some video cards cant correct for the overscan if the drivers dont have that.


component and RGB are very similar. so component is at best like using analog vga.

a plasma with 1024x1024 over HDMI probably does some sort of internal scaling to correct for the rectangular pixels.... thats how is displays over hdmi if you are putting in input from say an hd-dvd player which displays at 1920x1080p.

SO wrong.

I don't know what was happening for you, but the standards are totally compatible. It was likely an issue with your video card not handling the resolutions correctly through DVI and doing them correctly though component.

1024x1024 pixels isn't a bad thing - it just means you have rectangular pixels which is fine. It might not even need to scale anything.

Pure FUD

 

[taltamir]

did any of you successfully connect a computer to an HDTV over a DVI to HDMI cable?

I THOUGHT the standards were completely compatible, thats what I told every one at first... then I tried to use it. I have tried on several different HD TVs and not a single one of them would properly take a DVI signal from an HDMI plug...

AND the overscan issue is nothing to sneeze at either... because that means you loose your task bar, and windows / mac is kind of hard to use without a task bar.

Yup. Looks freakin beautiful too. Running 1920 X 1080 on a 42" Olevia LCD thru DVI to HDMI. Apparently it's just you having the problem.

i have mine hooked up right now and it looks amazing. the only game that didnt look approriate was crysis but i found out that all i needed to do was brighten the picture a bit and BOOM it was perfect. I have it hooked up now and i am more then satisfied. I watched gundam seed disk 2 yesterday through the dvi to hdmi cord and the picture was peerrrrfect.

 

[alanwest09872]

and i didnt loose the overscan because i had my task bar also. if i get time i will take pictures with my digital camera

 

[themisfit610]

It's all in the tweaking and configuration. HDTVs are a lot more finicky when it comes to display settings than LCD monitors. Often if you don't send a perfect signal, they don't display anything, or they will screw it up badly. If you can send a perfect signal (as the HDTV wants it) you will get a perfect image with no additional processing.

i have done it, and well...


on a linux box, so the intel gma drivers on ubuntu dont seem to work with overscan.. that said the nvidia drivers do correct for overscan, and its better than even using analog vga.


i've used my windows box to do this too (as the 2nd monitor for viewing divx) and it worked fine with a nvidia card... didnt try the intel gma

 

[alanwest09872]

well i got lucky my computer and plasma was perfectly setup right out of the box. which makes me really happy
