This question has most likely been asked before but here goes again. How do I hook up two(2) Sony 1080p TVs using HDMI to my computer?? Or one(1) Sony 1080p and RCA 720p TVs.
The MBO is a Gigabyte 880GM-D2H, ATI Radeon HD 4250. Am using a 720p 32' RCA on HDMI, and a AOC 2217 on the VGA port. The text is not clear on the RCA.
I found the Galaxy 61TGF4AM5UNX Geforce GT610 w/cables but cannot tell if the ends are HDMI.
Let me know of some ideas. Thank you

You can convert 1 of your DVI ports on the card to HDMI with an adapter or adapter/cable: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Went to Radio Shack and bought, for $20, a DVI to HDMI cable and plugged it in. The Sony, which is HDMI on both ends, will work but the RCA, DVI on computer & HDMI on TV, will not. Unplug the Sony and the RCA works. Plug the Sony back in and RCA stops working. This is going right off the MotherBoard(MB).
Will I have to buy another card to get both TVs to work?

According to the specs for your motherboard: http://www.gigabyte.us/products/product-page.aspx?pid=3...
...you can only use HDMI or DVI during bootup, not both. (See notes 2&3 under the specification tab)
However, try this: once you are booted to Windows, the 2nd display should be available. Set up your 2nd display as you normally would. It has been awhile since I worked with integrated video. So I'm just going from memory (weak as it is). Normally, only one video output is available during boot-up.

If it turns out not to work for you, yes, a discrete video card will then be required. In which case, you will probably have to use JUST the video card only. Don't plug into the MB for video. In all honesty, I forgot the HD 4250 was an integrated video chip. I was thinking you had a discrete card.

As long as you don't do gaming on your PC, a discrete card like the ones below are not too expensive.

Just be sure to get one with 2 digital video outputs you can use. (Not D-Sub)

Found out that I can only use HDMI or DVI by reading the manual and buying a cable and trying it out. Also got the HDMI to have sound by going into BIOS and made change.
Right now I have the Sony hooked up via HDMI & the RCA via VGA.
If I get a graphics card with 2 DVI I will not have sound out of Sony or RCA, correct?
