540 tunnel vision

[imactheknife]

So my unicorn 540 was good for a long long time. I turned it on and forgot for hours today that it was on. Came back, and notice it looked like a little tunnel vision starting. Weird that one little area on side but corners werent bad. I shut it off for a few hours and now looks good again but still, kind of sucky lol

I have never once seen tunnel vision start in anywhere other than the corners, odd.

Yeah me too. Was definitely weird. I could see the darkness around edges when i shut it off, but when it was on it still didnt look inverted like some of the 180’s i had. Could still see the little pixel squares etc even on the side darkness.
