+title: Samsung Odyssey+ Rewiring Project. (WIP)
+---
+
+So, you bought a headset from a multimillion dollar corporation, and not only do they not support it, they get mad at you for asking. Well that sucks. 
+
+This is an incomplete project; I have not been able to get this thing to power on.
+
+# What I know
+
+Samsung Odyssey is listed as HDMI2.0 + USB 3.0 Interface Bound Cable
+As far as I can tell, the USB is a USB A Superspeed cable.
+
+These wires have very low impedance (0.1 on my multimeter) to the point that I had to use headphone wire to make the connection. The wires are also very fiddly - you will want to use a very sharp knife to nick the thin cable, then gently slide the insulating plastic off the end.
+
+I also happen to know that HDMI is, supposedly, very picky about cable length, especially with twisted pairs. Cut these as close to the same length as possible.
+
+(get hi res glossy JPEGs of how friggin' thin these things are!!)
+
+Pre-join, the cable appears to be an HDMI 2.0 cable and a USB 3.0 Superspeed.
+The potted part in the middle doesn't seem to have any sort of electrical significance; taking passes at it with a razor, it mostly just seems to combine the two cables into one cable. Will investigate again later.
+
+Using a multimeter and an impedance test, I was able to test the connectivity of the colored wires in the O+. There's one that I haven't been able to assess what it goes to. (the light blue teeny wire)
+

+ impedance:
+ 
+ Long story short I tried bridging the gap with CAT6 wire, which is no bueno for HDMI. Any cable patching needs to be with something like 0.1 ohms.
