Digital video has proceeded to the point at which we have near-broadcast-quality HD production capabilities in the palm of our hand, and often for a surprisingly affordable price. One area in which the benefits haven’t quite made it to our wallets though is in the field of small HD monitors …read more
Having been endlessly regaled with tales of side-channel attacks and remote exploits, most of us by now realize that almost every piece of gear leaks data like a sieve. Everything from routers to TVs to the power supplies and cooling fans of computers can be made to give up their …read more

With some clever hacks and fast IO work, it’s possible to get your average garden-variety microcontroller to output some form of video. Old analog standards like composite and VGA are just slow enough that it’s possible to bitbash one’s way to success. If you’re serious about video work, however, you’ll …read more

USB Type-C itself is just a connector, and it supports DisplayPort Alternate Mode, as well as HDMI Alternate Mode, depending on the manufacturer.
Does this at all mean that if you’re using a DisplayPort or HDMI adapter in yo… Continue reading With a USB Type-C port, can you switch DisplayPort or HDMI Alternate Mode back to USB after using an adapter? [on hold]
Creating a video signal from a computer, a job that once required significant extra hardware, is now a done deal with a typical modern microcontroller. We’ve shown you more NTSC, PAL, and VGA projects than you can shake a stick at over the years. Creating an HDMI video signal however …read more
The lack of HDMI inputs on almost all laptops is a huge drawback for anyone who wants to easily play a video game on the road, for example. As to why no manufacturers offer this piece of convenience when we all have easy access to a working screen of this …read more
