Connecting a flat screen TV to PC with dual monitors already

there is also a software that is easier to use, but I forgot the name.

I'm already using dual monitors on my PC. I just wanted add/connect an additional LCD TV to the PC so I can watch movies in the big TV.

oh sorry. yeah you will need a splitter.

wala ba yang s-video? like 3rd connection?

I haven't tried it, and not sure about the quality, but it's worth the try using your s-vid to component.

I think I recall trying this out that end up one of the vga disabled. your card might be limited to 2 simultaneous output only. unless it's a new gen Ati radeon card. but it's still worth the try since it won't cost a thing unless you don't have the svid to component.

You guys might be making it more complex than it should...

If your motherboard has a built-in video, you could also use that.

The best method to use is to regard the LCD TV as another monitor. Connecting it to the pc would result in a triple-monitor setup.

Multi-monitor has been around for Windows since Windows 98. The traditional way to get triple-monitor is with multiple video cards/chips.

ATI now has Eyefinity which allows 3 monitors on one video card: 2 on the DVI/VGA ports and 1 via Display Port. Simply buy a DVI-Display Port adapter.

I think Powercolor also has a video card that comes with 3 DVI ports.

I just checked the rear of the PC, it has HDMI port pala. I forgot I already changed my motherboard. (tumatanda na talaga ako).

Can I use this HDMI port to make my setup triple monitor?

most likely puwede. but you may need to enable the hdmi always in the bios options.

Don't forget that most video cards allow just two monitors even if both dual DVI/VGA and HDMI ports are present. You need two video chips (either 1 video card + onboard video or two video cards)for triple monitor. At least, that's been my experience.

That's why Eyefinity is important. It allows 3 monitors on one video card. But, I don't think 2 monitors on the two DVI/VGA plus one on HDMI will work. On my card, it has to be one of the following configs:

2 DVI/VGA + 1 Display Port
1 DVI/VGA + 1 HDMI + 1 Display Port

Try it anyway. Maybe things have changed.

The HDMI port is on the motherboard, my dual monitors are connected to the video card, would this work?
