I am thinking about getting this screen. It is RCA I believe and so I will need a converter. If I bought that screen with this do you think that would work? Also, with that setup how is the screen being powered?
The stereo-to-RCA cable will work, and as per the top review of the screen (did you read it?) this screen works perfectly fine with an rPi, but you need a 12V powersource from what I understand:
This monitor, like I've put in the title, was bought for a Raspberry Pi. I didn't want to spend on anything larger than what was needed, and didn't want to connect to a TV at all, since the Pi is just meant to be a fun, homebrew-style computer, and I wanted to build it as cheaply as possible. With that said, the monitor is not only cheap, but it WORKS and works well.
First of all, in describing it, the screen size that you will get out of the box is about the size of a PalmPilot's (close to 3.5"), and it will come with a flexible arm and mini-stand attached to it that you can adjust however you like, with a sticker underneath in case you want to mount it to anything. In short, it is really a baby LCD flat panel.
On the back are three buttons: Menu, +, and -. There is no menu--simply press the buttons to alternate between Brightness, Contrast, and "Colorast" (or how much color you want--0 is grayscale), and finally OK or Reset. With that said, settings are very simple to configure on it.
Now, we get to the last (and fun) part. You can splice two cords together to get power if you wish, but I simply connected a 1.0 A (1000 mA), 12 V (and under 4 W) power adapter, which works efficiently well. I'm mentioning this to be helpful in case anyone else wants to connect this to their favorite little computer using an easier method. :) You can easily connect any spare yellow RCA video cable, and the picture is surprisingly clear! To get specific, with good enough eyes, you can read 12 pt text in Sans or Monospace (though anything lower becomes harder to read--although I can still read size 10) and this monitor drives a 656x416 resolution according to xrandr (a little bit under 640x480). This is with overscan on (which means the screen puts an artifical box around the screen so it fits better) and I recommend you turn this on. Without it, maximized windows will exceed the screen space, making things a bit monotonous. Now, without overscan, it does about 712 instead of 656 if I remember right. This is totally up to you. Also, I find tilting it up a bit on a desk, and sitting closer to it helps make the experience a bit better.
And so far... all my shells show up clearly, and everything seems to be working fine. There's barely any flicker I can see with my configuration, and it displays nicely. With all this said, that is the story thus far with this screen connected to a Raspberry Pi as a monitor, and I hope others find this helpful when setting it up. :)
