Use a laptop LCD to extend your desktop display

I get an email asking for this almost monthly, and [PUNiSH3R]‘s take on this covers everything pretty well. He uses some interesting tricks with WINE to get enough performance to play a DVD on the remote display. Yes, the cheapest way is to turn it into a remote desktop display over a network. Personally, I use synergy2 to share my keyboard and mouse, run multiple OS’s and keep my sanity.

    #1, that looks like a reproduction of an old DEC program called x2x from ages ago. Personally I’m not sure how I could have lived without it for the last, oh… decade.

    I’m surprised that people would find something like that so unbelievable that they’d need a video…

    Dang, and here I was hoping for some way to use the working LCD of an otherwise broken laptop. Guess I’ll still have to purchase a monitor for my workshop.

    anyone know if there is a way to do this with a palm?

    I think the title is misleading and should instead simply read ‘extend your desktop display’… while it is a clever repackaging, this is nothing more than a networked display that could be accomplished with any type of pc.

    Or there’s Win2VNC/X2VNC…

    Wow. There’s absolutely no way just to cheaply reuse the screen itself? That’s unfortunate, because using a 1.2GHz processor to power a 14.1 inch auxiliary display seems rather like overkill…

    Of course you can reuse just the display; but the WiFi is a nice feature. You could use minimal circuitry to feed a second (third…) DMI or SVGA or HDMI cable off your PC in and thus get a second display, but cables require so much high-grade plastic it is a serious waste. Adding a CPU at least capable of full-resolution h.264 playback and otherwise managing a limited wireless data rate gets you some pretty nice independent functionality.
    1.2GHz is not a lot of power in itself (not bad for 4 64bit cores, but 1.2GHz P-IIIs seem stingy), but if you can use a DSP or a video-specific chip of course you can save power and battery bulk.
    Better yet, doll up the case nicely, add some touchscreen and 3-axis accelerometer (or gravity sensor chip) components plus compact mics and speakers, and claim to have the Ghetto iPhone with XBASS. “Dates to Steve Jobs’ Breakdancing Days,” you’ll say sagely….

    its not that it’s unbelievable, its informative and cool as shit

    #7, Agreed. Why are all of the LCD driver boards so expensive?

  12. The screen works great on xp.I installed vista then uninstalled it.Vista is such a dissapointment. MS should give a credit to everyone who still has a receipt of Vista from wherever they purchased it. I hope i get a refund.

    You can also use MaxiVista to extend your main PC’s desktop to a laptop.

    So how do you use an lcd screen from a laptop with a dead mobo?

  16. Odo says:

    There is a free alternative to MaxiVista, called ZoneScreen
    It is slow, but hey its free, and it even works for WindowsMobile2003 PDAs!
