Display conundrum.

post #1 of 7
Thread Starter 
OK so I have a sony tv. It's just before the HDMI era, so has composite, rather than HDMI.

but my GPU has a HDMI-mini and 2x DVI.

I have an S-video in my tv, if thats any help.

all I'm asking for is some way to get my PC to use my TV as either a primary or secondary display.

If not, then I could pick up a used 8800GTX, but if i were to use the S-Video port on that, will my GTX460 still provide the main graphics workload?

S-Video is Analog. So you're not going to be able to use Mini-HDMI or DVI with your TV. Unless there is some special adapter from DVI to S-Video. Since DVI has analog pins in it.

What about DVI to composite?

I also found a HDMI to vga+RCW cable, can I use that?

I believe DVI will give you the Yellow connection for component. But that's it. DVI doesn't do Audio, so there will be no Red & White.

Also, HDMI to VGA is fake. You can't do digital to analog.

DVI, HDMI, etc. are all Digital.

S-video, VGA, Composite(yellow RCA), Component(Red, Green, Blue RCA) are all analog.

-Composite is max res of 480i IIRC.
-S-Video can do 480p and 540p(EDTV)
-component usually is used for 720p and 1080i, but SOME TV's will do 1080p thru component even tho it's not part of the standard.
-VGA, I'm not sure what the max res is. I've run 1080p+ over VGA OK, it's not optimal at all and is highly susceptible to interference, etc.

using a SDTV or EDTV as a monitor is not a good idea. I've tried it on several TVs, it all looks like crap. S-video or composite.

if you have an HDTV you're trying to use as a monitor you're gonna want to use HDMI or DVI(interchangeable sans sound w/ adapter), or suboptimal VGA. I know of no modern GPU that outputs component now days.

If you're dead set on getting VGA, DVI, etc. to your TV you'll needto buy a decently spendy adapter usually. S-video's still an option, and your best bet, but it will not look that great as even tho S-Video can do 540p or so, most TVs won't do that, and/or the GPUs won't output more than 480p.

edit: what's the exact model of TV you're trying to hook up so we can try to use the most optimal interface?

You forgot to mention that DVI is backwards compatible, Digital w/ Analog.
That's why you have DVI to VGA adapters.

That's because DVI-I and DVI-A have analog video and sync pins. there's essentially VGA in the DVI connector. the lil block of pins, and pin 8 make up strictly analog signals:

edit: there are mac adapters that are somewhat affordable that'll take DVI to s-vid/composite but I'm not entirely certain as to thier compatibility(it's apple, they like to modify and proprietary-ize existing standards). Looks like there are component adapters as well. Regardless you're still using an analog signal, and the res is limited by the interface and the display.
