Hello,

Any actual solution how to use kindle as pc monitor ?
I would like to use my Kindle 3 as normal screen for computer with Win7.
Because Lcd strain my eyes and causes headache. I tried to use PixelQi screen and mounted it into my netbook but is too sharp and also not easy for my eyes.
I can work only with eink without pain.

I know that it is impossible to use Remote Desktop from Win xp for that purpose. Any other ideas ?

I regret that I can not buy eink monitor basiclly with vga port.

I can not programming and do not know Linux very good.
So, could you please give me prepared solution step by step how to use Kindle 3 as Pc monitor with Windows ?

Thank you guys for helping.

Greetings from Poland.

It's not quite what you're after, but it's worth mentioning that the fullscreen native terminal, coupled to the ssh client installed with the usb networking hack, makes for a perfectly servicable wireless terminal. No graphics, I don't believe X forwarding would work as I don't think the Kindle has X running.

I've been controlling an otherwise headless server this way for a week or so, no problems with the refresh rate. I just wish it had a complete keyboard.

I am glad to hear there are others wishing e-ink monitor. I have coding skills, proffesionally, but just have little time ... I just went on vacation, this is why I have lots of time to search through my favourite topic on the web.
Yeah, I regret there is no biggers size e-ink on the market, preferably as an e-ink pc-display. I have only k3 but just thinking of developing that king of app to use it as a wifi display However it is bad that the bigger kindle does not have wifi, I mean, even if I write that app it will have to be upgraded to DX ready communication to be really usefull....
I really regret there is no bigger e-ink displays on the market, but stay tuned in the next two weeks of my holidays what the evenings could bring to the future of a manking

You could plug the Kindle DX into the computer via USB plug, and be able to operate it from that via USBNetwork.

If you develop such app please post it here. I will be very grateful to you.
I need to use Kindle as PC display to avoid eyes strain and headache.
Thank you.

Two solutions:

1. cross-compile a newer version webkit browser which can support HTML5 VNC client

2. develop a vnc client for kindle.


I tried solution 1 but failed. Now I am trying solution 2.

The idea of the software is very simple: skeleton windows display driver which captures updates of screen as bitmaps and sends over network-socket connection to the kindle. Kindle listens and captured images write to framebuffer. That's all

So far I have installed usbNetwork hack and scratchbox developement on linux. Wrote simple client server part, compilet in scratchbox the server part for arm6 little endian and it works However I have troubles with writing to the /dev/fb0. None of standard framebuffers tutorials works on kindle

I have downoladed kindle kernel source from amazon. Hopefully there is source code for eink driver. However the source seems very incomplete - there are special IOCTL's in this framebuffer implementaion which handle eink update however they are nowhere defined. I am not able to guess them (or at least I am not so patient)

Amazon sucks very much ...

Well, I see this topic is alive, that's cherish I mean, it's as usually, I did some hacking/coding but after a while something other attracted my attention...

This project is fun indeed. To make it usefull I think it should work through WiFi or bluetooth. The latter because of the SideShow API SDK mobile component this way lots of applications utilizing the gadget display could work right away

I wrote a sortof program that makes kindle as a second PC screen. The way it works is that it captures the screen on my computer, and then sends to kindle, and kindle then shows the image. It's like a media streaming system. The response time is terrible right now, it has a delay of about 0.5~1 second. I still don't know where the bottleneck is. The image I send over is zipped, the size for the full 800*600 screen is about 20~40k, and I only send over the difference between two consecutive screen shotshots, which is much smaller. Maybe the big issue here is finding out the updating area. Currently I don't have a good algorithm to get that out, so most of time, I guess, it's updating the whole screen.

A 0.5 second delay is pretty good. That's about how quickly you can turn through pages on the Kindle itself. Have you released the program yet?

I've experimented with screenshots myself, but the delay is about 6 seconds, even when connected over USB. I'm very interested in how your difference algorithm is implemented.

kranu, Substract each pixel from current screenshoot and previous (better from keyframe), then use RLE encoding. If most of screen not changed than resulting image will consist 0,0,0,0,....etc

Sounds like you need a Entourage Edge. Someone on the forum figured out how to show the tablet (LCD side) on the eink display.

well, xor would be a better option than subtraction.

The program is pretty rough right now. I might publish it when it's got polished. The key algorithm I used is:
on host,
1) convert pages to kindle framebuffer format, which would be 800*600/2 bytes long,
2) xor two consecutive pages as diff,
3) zip the diff, send over wifi.

On kindle side
1) unzip diff
2) xor the current framebuffer with the diff
3) find out the dirty area, this is where I don't have good algorithm
4) update the screen (only the dirty areas or the whole screen)
