Is it possible to find a VGA adapter that does


2x Female -> 1x Male


An example of what I want is:


PC -> VGA Out (Female)
_ <---- HDTV VGA In (Male)
Xbox360 -> VGA Out (Female)


I know you can do the opposite since there are Y adapters that do it. But I don't want to split the source into two, I want to take two different sources and push them into one receiver.

The receiver being your HDTV yes ? You are far better to use the HiDef inputs on the TV than VGA. i.e. the PC output it is preferable to use DVI-D to HDMI in. The same with the XBox360 either the composite or HDMI output from the Xbox into the TV.

The reason for this is that the VGA output is not a digital output but rather analog and does not overscan. The difference is that images will seem more jerky using an analog rather than digital input and of course the Xbox360 will not display at optimum resolution.

Agree with Art. I had gotten a DVI->HDMi cable or even an adapter but deff use HDMI. I'm sure you have more than one on your TV if you have a VGA in right?

Extra emphasis on those comments: my TV is full 1920x1080 pixels, but it will only accept vga up to 768x1366 because of the need to convert analogue to digital. Still, if you've no alternative I suppose it might be better than nothing.

I can't see how you can have a cable that connects two outputs to one input - potentially you would be trying to merge 2 signals, and that means that if one of the signals was not present then it would have to pull down the level of the other signal.

There's one thing that might work though - what about a two (or more) port KVM switch? A physical switch (as opposed to an electronic one) would not need a keyboard or mouse connected. You won't get automatic switching (but I can't think of any way that you could) but it might give you the connection options you need.

Thanks for your replys.

I should have prefaced my post by saying that I don't have an HDTV yet, I am still working out deals vs. input types.

I did not realize that the VGA connection was an analog connection. I assumed it was digital.


Yes Detale, I'm seeing a standard of 2x hdmi in then a mix of vga or vga + dvi.


I was thinking that I'd use my existing xbox360 vga adapter and use a KVM type switch to utilize two vga sources.


Now that I really think about it, if I can focus on getting a TV with DVI to accept my video card output DVI-I via geforce 7600gt, then a HDMI cable for the xbox360 that would be the best solution.


@lynx, I see that the VGA connection has the resolution problem (limited b/c of the analog -> digital conversion rather than the limitation of the HDTV resolution), but is it the same with DVI? Can DVI scale to whatever the max resolution of your HDTV is?


It would be a pain in the butt to have to swich the input sources on a KVM switch.

You can get DVI to HDMI adapter cables. But you won't get audio through it unless your video card supports that (not sure what ones do). If you went this route you would need a tv that can accept an external audio source while accepting video through hdmi.

I have 2 monitors and 1 TV connected to my video card at the same time.

My video card has 2 DVI outputs

1 is a CRT monitor so I use a DVI to VGA converter
For the LCD monitor and for the TV what I have is a powered DVI splitter from www.monoprice.com (http://www.monoprice.com) it splits the DVI signal to 2 devices from 1 source. My TV connects with a DVI to HDMI cable.

I can watch High Def movies or anything on my LCD monitor and my TV at the same time. You should get a powered splitter or else you will lose lots of picture quality.

This setup cost me like $100 CAD though.

If you only have 1 monitor and your video card has 2 DVI outputs you only need a DVI to HDMI cable like tesco said. Which will be much cheaper. Of course you would get no audio on your 360 this way. If you have the 360 HDMI cable that has optical connection, you could hook up to a optical receiver. Or if your sound card have optical in like mine that would work too.
