3D Blu-Ray + Proper CRT Cadence w/ Raspberry Pi3

### The Ultimate Retro-Tech Hack: 3D Blu-Rays and CRTs
If you find yourself living in a very specific niche—one where you crave both the immersive depth of 3D Blu-ray playback and the buttery-smooth, flicker-free cadence of a vintage PC CRT monitor—then pull up a chair. You’ve just found your new favorite weekend project.
It turns out you can use a single Raspberry Pi 3 to master two completely different worlds. By using an older version of LibreElec (v9.2.8 specifically), you can unlock 3D .iso playback on compatible flat panels while simultaneously configuring the Pi to output the perfect signal for CRT monitors.
There is, of course, a little bit of “retro-engineering” involved:
- The Hardware: You need a Raspberry Pi 3 (the B+ version is best). The newer Pi 4 and 5 lack the specific decoder chip required for this 3D magic.
- The Software: Since modern Kodi versions have dropped support for this feature, you’ll need to manually install the older v9 software and potentially “borrow” some firmware files from newer builds to ensure a smooth boot.
- The Magic Trick: By using “EDID spoofing,” you can trick your display into accepting higher refresh rates (like 72Hz), making your CRT content look incredibly fluid.
It’s a bit of a technical scavenger hunt, but for the enthusiast who refuses to compromise on either 3D depth or retro clarity, it is well worth the effort.
