I still have a few CRTs, and have one hooked up to a VHS deck that also goes to a Teranex 2D for upscaling. CRT shows me the before (4:3) to compare to the upscaled HD on LCD TV. I also still test DVDs on the CRT (usually at least one project a year) for fielding issues.
I have a couple with very low hours I haven't used for years so they are just wasting space... I thought about pairing them with old gaming systems that use composite or SVideo outputs for those building retro gaming systems or arcade cabinets... However, most are using Raspberry Pi with HDMI output to run emulators but IMO the CRT displays better NTSC or PAL video than affordable panels. IMO they always handled interlaced video better... Ya know the moment I sell them I will think of a great way to use them here...
@Grazie ... just a thought ... a donation to the Science Museum in South K. The last time I was there (quite a while ago unfortunately) there were displays of 1960s record players and other similar tech. Back then in 2003, they even had an an early AMPEX 2" video recorder, though that didn't compare to the Babbage 'computer'.
The only reason I suggest this is that so much gets junked that little actually gets to survive to end up in a worthy museum.
