Laptop screen with rpi?

Thu May 24, 2012 6:17 am

Hi, I recently ordered my raspberry pi, and was just wondering whether it would be possible (and fairly simple) to use a laptop screen as a monitor for it? If someone could give me an answer or some advice I would be really grateful! :)

It probably won't be possible to use your laptop display directly because there won't be a display INPUT to the laptop, only an output. You can do it indirectly by connecting remotely using SSH to get command line interface or VNC to access the desktop. There is lots of good advice around on these subjects but I have some basic notes on how to set them up here: http://www.mydominion.co.uk/?page_id=64

You can but it's not as easy as pugging in an HDMI cable. You need a HDMI/DVI to LVDS converter (assuming your laptop screen knows LVDS - most do).
I am building a converter for a 8.9" WSVGA screen (used in some EEE PCs) but you can find them on ebay also. When building your own, it will be a little cheaper and maybe smaller but if you don't have experience, I recommend you buying one.

I know in a recent interview with Eben via Engadget he mentioned a possibility of an LVDS addon for the DSI connector on the board.

If you already have a laptop panel and don't mind taking chances there is also this

I researched this before for another project, they have a list of supported models of panels.
In addition to the controller board you will need to buy an inverter (they provide one or there are universal ones available on ebay)

The seller offers a kit with everything you need.

Yes, maybe the hardware will be more or less there, if you ignore you need a very specialised "flexible PCB cable" to connect to the DSI port, but you ignore one very important thing, and that is you need a driver that supports your LCD panel, in all its parameters, and that driver can only come from the raspberry PI foundation.
If the driver the raspberry PI foundation releases isn't exactly right for your random LCD panel, it simply won't work! perhaps the RPF will release a "tweakable" driver, but nobody know that as of yet.
Perhaps they will release a driver that only works with one single panel, theirs.

How about you skip the trouble and buy a $35 hdmi board for the screen, attach the screen to the hdmi board, plug In power, plug in hdmi and voila!

Where do you find those hdmi modules you are talking about? I haven't been able to find anything.

You might want to check out the Motorola lapdock. It's a dock for their Atrix phone, but one of the ports is a mini hdmi input. More importantly, they are on sale as the phone is getting replaced my newer models. Originally ~$300-400, you can now get them for $50-$60 if you are lucky. With some slight cable modding the keyboard AND trackpad can be connected too. Bonus points for built in battery to drive the RPI.

I've got the dock and RPI, just waiting for the cables now...

If that question was directed at the post above it, many others have done so, search the forum for "lapdock", a handful of active threads.
