I contacted Pixio about the line down the middle of the screen and they offered to RMA it (not knowing I'm outside of the 1 year warranty lol). I said I don't want to RMA but I'd try different firmware. They sent me a link to the V6 firmware and said it was the most stable. Can anybody confirm?
Here is a Google Drive link with the V6 firmware: https://drive.google.com/open?id=1-G..._e3VX38cAp_uMD
I'll add more firmware if people can get it to me.
