Laptop to 2 Monitors?

post #1 of 12
Thread Starter 
Is it possible to connect a laptop to two monitors through HDMI?

*Assuming the laptop has only one HDMI port, is there an HDMI splitter that exists?

*Would these monitors display the SAME desktop twice, or could they be used as EXTENDED screen space?

*Would this require a powerful laptop? (ie. needing a dedicated GPU, i5 or i7, etc)

Yes, if the displays support daisy chaining. You will need a high quality HDMI splitter/box though.

Well you could theoretically split the signal, but extending is out of the question. The only thing I imagine possible is to mirror the image. Though I doubt the onboard card can handle it.

So how would that look?

That's something else I'm curious about. The GPU power that would be needed. I'm talking anywhere from 23" to 42" screens. Obviously that's a large range, but I'm curious what would work.

Bump.

1) A laptop without a dedicated GPU couldn't handle multiple monitors

I think that's kind of debatable. My laptop can output to a 32in TV, so then it could probably handle two smaller monitors (2 x 19in?).

2) How much would this "splitter" cost? What would it look like?

that is what you need...buy 3 and you'll have 3 external monitor

click on the customer pics...that is what you want right?

What about connecting one to HDMI and another to VGA? That would do exactly the same thing as 2 HDMI, but I think VGA has slightly worse quality(?)

I guess I could try that...that wouldn't run the risk of messing my laptop up would it?

I feel like its my duty to clear this up. The screen size of the display is NOT a factor when it comes to the processing power that the GPU needs. For all the GPU cares, the display could be a 9001" TV, or it could be a 0.005pico" display. Its the resolution that counts. In terms of graphics horsepower needed, a 0.005pico" display @ 1080p needs the same power as a 9001" TV @ 1080p. Nothing more, nothing less.

Regarding this topic, as long as the laptop has the ability to slip the output into two different channels, there is no way to do it. Unless, you buy the EVGA usb thingamabobby or similar. A normal laptop is quite capable of powering two displays if all you're doing is word processing/browsing. Don't expect to game on two displays though.

Word is, there is an external PCI slot that can accept a modern GPU. The extention plugs into your laptop's express card slot (assuming you have one), two which you could then plug in a GPU. That way, you can have an actual dual display setup, while still using your laptop as a third screen. Where to buy one: http://www.hwtools.net/adapter/PE4H.html

Scroll through to find one that works for your system. A word of caution - its still an engineering sample of sorts. It'll work, but its not an elegant solution.

Well I have a 13" without a PCI slot, so that GPU thing won't work anyway rolleyes.gif

So were you saying I CAN split it up? I've got one HDMI and one VGA, can I hook up to two different monitors and use them to extend my desktop?
