Sekonic 758DR screen uneven brightness?
I've been using that same meter for quite a while now. I've never had any problems like that. Sometimes cold weather can cause problems like that to LCD screens, but I've never noticed that on my meter.
You'd probably be best off taking it back to where you got it, and ask for a replacement.
