Great idea, I might do this myself. It's actually much cheaper than that - I'd say around $400. 1) Get just the panels off ebay for $60-$80 /each. 2) You can get the spec sheets for the panels with enough Googling. It's a 6-bit (yeah, not 8-bit) LVDS signal, same as most modern laptops. 3) The toughest part. Create a DVI-> high-speed LVDS converter. There might be something already available, though. A quick google only shows a Toshiba DSI -> LVDS converter capped at 1080p. Ballparking the LVDS clock rate: 2048 * 1536 * 6 * 60 Hz = 1.1 GHz Interesting idea, though.

I would have hoped that displayport would replace LVDS, which would allow theese kind of hacks to be much easier and a lot cheaper. Have laptops made the switch yet? (since they use displayport externally seems like it would be in their interest to use it internally as well) In that case the new MPB panel would perhaps be more suitable (and probably cheaper in the end - as well as better quality (I'm assuming/hoping it has 8 bits, but I don't know)). And with displayport you could just hook it up to a decent gamer graphic card and be done. I'm not sure how feasible 2048x1536 is for a single-link DVI (at 60 Hz you would probably be in trouble), and graphic cards with 4 dual link DVI connectors isn't exactly mainstream so you would have to get (at least two) active displayport to DL DVI adapters, and they are not cheap either.

It is a common misconception that DVI is limited to 1080p. The standard provides a budget of 165 million pixels per second, shared between active image, blanking and frame rate. It's easy math to figure out how far it can go based on a given frame rate and percentages of non-image time. I remember doing the math years ago and the results were well beyond 1080p. I don't know the Toshiba DVI->LVDS converter you are referring to. I have personally designed a couple of them and they have non such limitations.

  Hey, can you email me at garbage1234@live.ca ? I'm interested in a DVI->LVDS converter, would like to talk with someone who has worked with them in the past.
