XFX 8800GT SLI and Vista Aero @ 1080i

[necrokiller]

I have my PC connected to Sony Bravia 46" through the S-Video to component video adapter. Im running at 1920x1080 @ 30Hz. I have the latest drivers installed. All games run great as expected. But the Vista Aero interface is lags alot. The minimizing, resizing, 3d flip and all animations and effects are very slow. It works perfect on my LG 22" monitor @ 1680x1050. Im just wondering if the slow performance has something to do with the fact that Im using the s-video cable or the TV's refresh rate. Any help is appreciated.

If I were you I would byu a DVI to HDMI cable for that application. I bought one for my monitor and I can see a huge difference on a monitor so I know you see improvements on the TV. These cables are about $20 from the local puter store or maybe a little cheaper over the web. Hope it helps.

It's probably just downconverting the video to 1366x768, if it's a '1080i' set. 1080i is a big lie, 99.9% of sets that support it have a lower native resolution and must perform some form of processing to show the image. Usually looks pretty horrible, too.

Try connecting with either DVI->HDMI, or component cables, and run at the screens native resolution. What model number is the TV?

Model number is KDL-46V2500. So basically if im able to select 1920x1080 from my PC, when connected to the TV, its actually less than that? The TV also has a PC input, so I can connect my computer directly using a regular monitor cable, but the highest resolution supported is only 1440x1050 using that feature. My only question is, even if it is 'down-converting', the resolution has decreased, which should make the Aero performance better ,not worse. I had this setup on my XP and the results are very very impressive. Games and movies looked amazing.

That 'S-video-to-Component adapter' is really not converting S-video to Component. That jack on the back of the video card looks like an S-video plug, and will output S-video if you plug an S-video cable into it, but it has extra pins in there so that the adapter you have can send out a component signal. The problem I've seen is that component out on these cards just doesn't look that good. Also, your TV most likely won't accept 1080p via component even though the standard can technically support it. Has to do w/ HDCP (copyright BS). It ends up sending 1080i which must be processed by the TV to 1080p before it can be displayed. In essence your gfx card must interlace the signal before outputting it, and then your TV's built-in de-interlacer is de-interlacing it before sending it to the LCD panel. 2 unnecessary steps that will only degrade your image.


Your TV is native 1920x1080 (1080P). Do yourself a favor and go buy your self a DVI-HDMI cable online for $15-20 and see what that TV is really capable of.

Yes, thank you. Ive already started looking around for good deals. But would that really fix the PERFORMANCE issue? Its not really the image quality that im worried about. Ive been playing games which allow me to turn up the resolution to 1920x1080 and the results are pretty damn good. Now I know like you said it could be even better but that would be hard to notice. Whatever the case, if the DVI to HDMI cable fixes the Aero performance issue, then ill buy it. Otherwise I dont really feel the need for it. But since they're so cheap, I might as well should get it.

PAH!

More like $8

Anyway, the quality will look SO much better with these:

Thanks alot for the links man. But im in canada. I still comes around to $9 which is pretty damn good but the wait is too long. 7-14 business days. And whats the different between these Female and Male cables? :S

um, source? Not saying I don't believe you, but it seems a bit sketchy, especially claiming 99.9% :-/.

Male has pins, female has sockets.

You want male on either end.

If it's a 1080p set, take your pick.. DVI-HDMI cable, or VGA cable. I use a 20 foot VGA cable for mine, and it looks great.

[the_cultie]

Or you could do what I did, get a DVI to HDMI dongle and a regular HDMI cable. Might cost a bit more but it means you have a regular HDMI cable in the event that you dont need to connect to a DVI port.

Many TV's won't accept 1080P over VGA even though the cable can technically support it. Once again, HDCP at it's finest!

I use a DVI cable, and a DVI(female)-HDMI(male) adapter. This might be the way to go if you already have a spare DVI cable.

I do have one HDMI cable, but no DVI cable. I think a DVI-HDMI cable or a dongle would be a good choice, whichever I can find cheaper. The VGA cable only does 1440x1050 on my TV, which is no where near its native resolution, so I dont want to do that. Thank you everybody for your input.

I bet it looks like garbage over Component.

Buy a DVI-HDMI adapter and a DVI cable. My samsung 46" on my xfx 8800GT 256 is running @ 1080p through HDMI

Hmmm the difference might be HUGE if people claim it looks 'garbage' over component cable. The text does not look clear, but games and movies look pretty good.

Why an adapter and a DVI cable? That doesnt make sense. Do you mean DVI-HDMI adapter and HDMI cable? Just one DVI-HDMI cable wouldnt give the same results?

[jason4207]

If the text is blurry i consider that bad.

[DVI(m)_HDMI(f)_adapter + HDMI_cable] = [DVI_cable + DVI(f)_HDMI(m)_adapter] = [HDMI_DVI cable] All these DVI-HDMI solutions are equal. Just pick the one that will be cheapest for you.

Aggreed, if you already have a HDMI cable the DVI - HDMI dongel will probably be the cheapest. Here's an example on Newgg and it's only $5.19 Link (http://www.newegg.com/Product/Product.aspx?Item=N82E16812226015)

Thanks guys! :)

I think ill go with the cable. The dongles are a bit hard to find and I want one right away, dont want it shipped. So an adapter would cost just as much as a cable. Anyway, I was wondering which of these two should I look for, and what are the major compatibility and performance difference between the two (I need a DVI-Male to HDMI-Male):

Can someone figure out the issue, I finally got DVI-HDMI cable (24-pin DUal-Link)...and Im still getting the output at 1080i not 1080p. What am I doing wrong? TV specs are posted above. Thanks in advance.

You have to do custom resolution and select progressive.

Thanks for your help but unfortunately custom resolution was not the problem. I had to change the signal from nvidia control panel from 1080i to 1080p. other than that, Ive read many ppl have had issues with Sony TV's especially that the edges are cut off by an inch or so from all sides, if any of you still have that problem, resizing from the nvidia control panel would just make your image quality poorer and still fuzzy. What I did was change the "Display Area" setting in "Screen" settings from the TV from 'normal' to "Full Pixel". Now I have the best the most crisp image quality and text comes out perfect too. Im glad I got the DVI-HDMI cable. Now even I would say that DVI-Component looked crappy.

[jason4207]

Glad you got it working right!

Males have something sticking out, female has holes. Got my drift?
