2 HDMI Video card

I'm looking into putting a 2 output HDMI video card on my machine and wanted to see if anyone can give me some good recommendations?

My system is-

Intel i7-3770 @ 3.4 GHz
Motherboard is Dell motherboard model 0NW73C and a GeForce GT 620 video card now
16 GB RAM
64 bit operating system on Windows 8.1

thanks
 
What would you use the two monitors for? Given your GT 620, I'm assuming it's not for gaming?

Edit: I looked up your motherboard. This claims it has an HDMI out. If Dell's BIOS will allow it (it might not) you should be able to get video out from both the onboard and discrete graphics at the same time. If you can do that, do you only need one HDMI port on the video card now?

This is an option that I myself haven't fully explored, but I'm confident it can be done -- others have done it. You then have two effective graphics adapters and two drivers. I briefly confirmed that I can get an extended desktop on the integrated graphics hardware.

But you can't manage a multi-monitor/multi-adapter setup with only one adapter "control panel." I can imagine situations where that would be possible. But with the onboard graphics of prevailing motherboard and CPU choices, not likely.
 
Not sure if I quite understand your situation. Unless your monitor doesn't have any other inputs or has speakers, you really only need one HDMI for the TV. That said, if you do only have HDMI inputs you can get any card really with an HDMI and Displayport/minidisplayport. From my experience, most video cards with displayport these days if bought new come with an hdmi adapter anyway.

NO doubt. One can only speculate as to how or why graphics cards are designed the way they are. Obviously they want the card able to interface with any single monitor: VGA-analog, DVI-I or DVI-D, HDMI -- Displayport. The VGA problem is resolved with the DVI-I ": | :" pinouts that carry an analog signal in addition to digital; a dvi-to-dvi connection for DVD-D will fit the same port, or you can use a DVI-I to VGA adapter plug.

Those wishing to drive more than one monitor with their graphics adapter will likely need to accommodate themselves to two different interfaces -- except for DVI, since you usually get a DVI-I and DVI-D port on the card.

You have to choose your cables and monitor "limitations" to conform to the ports available on the card. At the extreme, I think I've seen "TITAN" cards with nothing but some four Display-Port outputs. I was a fool to think that's a disadvantage -- it shouldn't be. It should instead simplify things. But those cards can cost above $1,000. For an HDMI connection, I think we're currently stuck with 60 Hz refresh rate, and use of "converter cables" with DVI at one end and HDMI at the other impose the same limit.

You don't NEED two HDMI ports to drive monitors featuring only HDMI ports. You can run a DVI-I to HDMI cable with no loss of HDMI functionality, but you're limited to 60 hz.
