This looks very interesting!
Small HDMI screens are expensive. Native HD ones are astronomical. We want to drive the price down "Raspberry Pi" style.
You'd think that, with the massive growth in tablet computing, it should be an easy matter to...
- get hold of a small high-definition (HD) screen
- connect it to an HDMI driver board
- hook that up to your Raspberry Pi (or other HDMI device).
Sadly, it's not quite that simple at all, or we'd all have done it already.
The Raspberry Pi can display full HD (1920x1080). You can buy a full-size monitor at that resolution, but that's not what we're about. We're looking for something small and portable. That's where it gets a bit tricky.
There are very few small, portable, HDMI screens available on the market. Most of the ones out there have 800x480 or 800x600 pixels. These are largely aimed at professional photographers and videographers (with a price tag to match!)
Some sellers are a little bit sneaky, making you think their screens are HD because they have HDMI connections. HDMI is the High-Definition Multimedia Interface, not the screen itself. They scale down the resolution to fit the number of pixels. And most of these screens sell for way over £100 ($150). I think that's giving too little and taking too much.
I want a screen that's both HD and HDMI. I want to HD MI Pi. But I can't do it on my own.
