@earnestrichards said in Disassembly a Dell U2715H:

I had the same question when I started work on my ‘mirror’ earlier this summer. I had purchased a HP monitor and found a link for 3rd party recyclers to properly disassemble and recycle the various monitor parts.

I used the same search term (except Dell not HP) and found this:
Dell Monitor Disassembly

Thank you, 24h after my second email I got a perfect disassembly instruction. Unfortunately, the pdf is to big to upload it here.

@ZombieDE IMHO, no it’s not worth it. Unless you’re planning on using your Pi through the mirror for surfing, video or the like. But if you’re planning on going with the normal black and white theme for the mirror, it’s not worth the extra color fidelity. I’ve found that with a little fiddling of the monitor settings (contrast max, brightness 40%, etc.) you can remove any background bleed from the LED backlight.
