TV-OUT issue with GF4Ti4200

[thatbox]

Alrighty. I got my Abit Siluro GF4Ti4200 64MB with DVI-I, VGA, and TV-OUT. I've got two monitors working happily, but nothing is being sent to the TV. As in nothing at all. I've reinstalled the drivers several times (I'm using WHQL Detanator 40.72s right now), but the software can't even tell that my TV is connected (TV is ghosted out along with DVI [both my displays are analog]). What's the deal here? Is it something actually wrong with the card itself?

As with all dual display cards but the laughable Matrox Parhelia (tri-display) you get DUAL RAMDACs which mean if you're sending signals to 2 CRTs you can't send a signal to your TV, try unplugging your 2nd monitor and then plugging in the TV lead! That's my best guess anyway.

I've tried simply unplugging and rebooting and replugging everything in all manner of combinations. Hmm. Maybe if I tell it to stop using the two monitors, it will work, since I havent told windows to quit sending anything to it yet. Thanks!

Also give TVtool a try, I believe there's a free trial version, in any case it's well worth trying as it gives you a significantly better TV picture and plenty of tweaking options too.

Yes! You must only enable ONE monitor to use tv-out.

Alright. I disabled my second monitor in the display properties window. I unplugged it from the card. I shut 'er down. I plugged in the s-video cable to the card, and then to my s-video > RF converter. Turned on the tv, turned on the comp, absolutely nothing. Went into display props again, and told it to detect devices. Nothing but my original main monitor shows up. I'll try uninstalling the drivers and then installing them with only the main monitor and the tv hooked up. this is becoming a ginormous pain.

humm thats odd. i run a dual set up in my TI4600 and when i plug it into teh TV it shows up. and when i send teh signal to teh TV it just shuts one of the moniters off

make sure you are using a low resolution and refresh rate no more than 60hz

It is very odd, never had any probs with my 4200 TVout (other than nVidia's lazy ass aproach to tweaking the signal). thatbox if you go to Display Properties (r.click desktop, properties, settings) you should have a big 1 and 2 which will signify '1=your main monitor' and '2=your 2nd monitor' (usually via DVI-to-CRT), click on '2' and tell windows to use the 'generic TV' driver for it. I don't recall having to do this but give it a try. The refresh rate shouldn't matter either, all GF4 should be equipped with dual RAMDACs meaning your TV should happily run at a diff refresh to your main monitor simultaneously.

Not true, I have had few Ti4200 cards without dual RAMDACs.

Maybe the card has issue with the card itself.
