Quick and Easy External Displays for Raspberry Pis etc.
Occasionally one of the RPs crashes and since it's headless I can't see why it's rebooting. It's always awkward to put a full screen display on it. Can anyone recommend a small LCD screen (maybe 1024x768 or 800x600) with HDMI to use? Alternatively I've a number of retro systems which use RCA, Scart, VGA etc. and had a lot of success with early gen LCD screens (12"/14") cheap from car boot sales for around 10-20 quid. Although they usually have loads of ports, I've never seen any with HDMI. Do these exist? Or is any sort of cable/converter possible? I think I used to be able to use DVI as HDMI (?) But I've not seen DVI on these either. -- Steve Mynott <steve.mynott@gmail.com> rsa3072/629FBB91565E591955B5876A79CEFAA4450EBD50

Cable converters work. I've used several HDMI to VGA converters like this one https://www.amazon.co.uk/Adapter-Compatible-Projector-Chromebook-Raspberry-B... Obviously if your PI has a micro/mini hdmi, you'll need to add an extra converter cable to get it to full-size HDMI first. Steve

I use one of these: https://smile.amazon.co.uk/gp/product/B089D8DB44 It is basically a USB video capture "card" and you can view the incoming stream in any video capture application. These are also the basis of Pi-based IP-KVM's that I've wanted to try for ages but never gotten around to. Whatever solution you go with, keep in mind that by default the Pi checks whether there is anything connected to the HDMI port on start up and switches the port off if not. So you can't plug a screen in later and expect it to work without a power cycle, often the thing you're trying to avoid. I think there is a way to have it permanently enabled but I don't have that to hand if so. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
