Small display (e.g. 7" or so) for use with Pi - where can one buy?

I'm after a small screen to use with a Raspberry Pi, 7" or a bit less would suit. Is it possible to buy such a thing at a reasonable price?

low res and pretty basic quality. I have one of those somewhere that I've never used, I'll see if I can dig it out and see how bad it is. :-)

If composite is good enough (as opposed to hdmi) then Adafruit has one for $75. All their displays:

unfortunately without sorting option.

I'm thinking I may go with an LCD character display instead.

Is composite usable at all, apart from larger scale gfx? Memories of

1980's computing in 40 columns: OK, but 80 columns: eyeburn!

It all depends on bandwidth.

If the Pi composite output is not bandwidth limited in the luminance signal, and the composite monitor has 10+ MHz bandwidth in its luminance channel, then 80 columns will be quite usable (though perhaps not "crisp").

If either the Pi or the monitor limits the bandwidth to the broadcast standard, then 80 column text will be unusable.

My radio shack computer uses a 7-inch tv with both composite and vga inputs. Runs off 12V too. They were selling them off cheap when tv went digital only. Quality is ok on vga, not tried composite.

Composite outut is fine if you have a device to support it:

is a crappy phone camera photo of a Pi connected to a ~30 year old monochrome monitor in 640x480 resolution. It looked much better than that in the flesh, as it were...

If you're happy using the composite output, keep an eye out for second hand portable DVD players. A lot of models have a composite input jack, and I regularly see them at car boot sales for about a fiver.

They can be had on ebay for less than that, but by the time you add in shipping they generally work out about that sort of ballpark.

moment, if one is near you it could be a bargain.

The Gamecube came with a 5" composite screen,

It's the sort of think that could well end up in an oddments box in a charity shop.

What are you precise requirements? If the alternative is a character display I'm guessing not much. If a small CRT is acceptable you have a couple of options - small black & white TVs used to be quite

or so but now you're looking at ebay or similar following digital switchover. Some have composite inputs but admittedly not the majority, so it's something to check up on first. CCTV security monitors were a similar size and a composite input is pretty much a given, but you might find one difficult to track down at the right price.

A slightly better option albeit with more hassle would be one of the small mono monitors used for EPOS systems - they're typically

8 or 9 inches, good for at least 640x480 if not 800x600. They'll give you a better picture but need a VGA input so that's a layer of conversion to go through. Whenever I've seen them come up used

around and bide your time they may be an option worth considering.

Taking a quick glance at ebay shops I would say less than that site is selling them for. Those horrible 7" TFT reversing camera/CCTV monitors are more like 25 to 30 pounds.

Or if you look for portable analogue tellies they will have a mains power supply etc (and might be even cheaper because people want rid of them now they are useless for their original purpose)
