Using a TV

Well I managed to get a 27" TV with S-Video.

I hooked it up to my computer with a ATI 32MB RageII 128 video card.

The picture seems really fuzzy :( I've tried to correct it using the ATI utility tha comes with the drivers for the card. The screen itself looks great when used as a T.V just seems to be a problem with the settings when running off the PC.

Whats weird is that when I set the DPI/Text size at 200% greater that the normal it lloks good. However, you have to move the mouse around to scroll the screen etc.

Any suggestions anyone?

When you say it looks fuzzy, what is it you are looking at.

Have you tried running mame on it.  On my cab the regular windows screen looks crappy but when Mala kicks in and I play mame, it is all good.
chrimeg:
By fuzzy....I guess blurred.

All the text under Icons, window buttons etc is broken/pixel-lated.

When I set the resolution really high nothing fits on the screen and I have to move the mouse to scroll the screen around.

I'll try and take a picture to show you guys.

What resolution are you guys running on 27" T.V's.
Afterburner:
Keep in mind that resolution of NTSC TV's is typically only 320 x 240.

Some CRT TV's will support resolutions up to 640 x 480, but these are rare.

I think the "enhanced" TV's may run up to that as well.

But yeah, if you set your resolution on the PC any higher than the native resolution of the TV, it's just going to give you a really big desktop with the scrolling you are describing.

Set it lower.

There are a few factors at play...

 One thing is that the Older ATI cards have much worse tv out signal.   I believe that might
be the case with your current card.

 Also, some TVs have better or worse quality.

 My TV has automatic interlace capability, and component inputs.   So, when getting an svideo signal, its crystal clear.  I believe its capable of 480i resolution.  (640x480)

 Even tho my tv isnt supposed to support resolutions higher than 640x480..   I recall that my
last ATI card was able to pump 1024x768 to it,  by using a sort of software interlace trick.


 If your tv is an older model, and cant do interlacing... it may not be able to show a picture that
is very clear at all.

 If your software is trying to interlace, and sending out more info than your poor low-res tv can
display well..  its probably causing the problem with poor output.
