View Full Version : DVI output... maxing out?

I have tried a cheap PC Nvidia card and tried to use my 57" HD Sony Projection TV. It looked aweful.

I've seen that S-video is only optimal to ~27" inches.

Does this apply to DVI?

can the powerbook G4 handle 57"?

the 64MB video memory, or the 128MB? does it matter?

Thanks again,
ryan

it a question of your projector resolution and it's specs rather than your video card in this case.

in general, TVs will look terrible when trying to hook up a computer.

unless you have HD or an lcd tv/computer monitor, a TV has one resolution and that is "suck"

What about a HD-ready tv?

--- and also, it's not a projector. It is a rear-projection HD-ready TV.

Thanks again,

DVI connections will look better than S-Video, obviously. The 57" part isn't the issue. As others have said, the resolution of the screen is the issue - in particular, the number of scan (horizontal) lines.

Which TV do you own? Model number?

If you own the SONY KP-57WV600 57" 16:9 HDTV Projection Television, the owners manual specifically says that PC video cards will not work with it. See attached image... (click for enlarged view).

It's actually a KP-57WS510, but you're close. Do you know any upgrades in that area on this model?

Also, the tv can accept all the standard resoultions: 480p 720p, 1080i... all that jazz...

but is there a way to force the laptop into sending this signal? or is there any way to digitally modulate the signal?

Thanks again for all the good info,
ryan.

As far as I know, there's no way to 'fake' the HDCP (high def/copy-protected) format. Could be wrong, though...
