A few weeks after the return of my screen for the V002 firmware update I've encountered a strange problem.
Three quarters of my screen has become blurry/blocky when viewing text. The left hand side of the monitor displays text under desktop icons, in browsers, documents etc very poorly. When I drag the same icons or docs over to the far right of the screen (the last quarter) the text appears properly.
This problem is not noticeable in games.
I've found one user on Reddit experiencing the same problem, I posted in response (jaibones).

Any thoughts on this issue greatly appreciated, I've tried resetting the monitor to factory default settings to no avail (forgot how awful it looks 'out of the box' .. ow). Really hope I don't have to send it back to BenQ ... again!
[edit] I should add that I'm sure it's the screen, after trying to roll back GPU drivers, trying HDMI lead, adjusting clear type, disabling hardware acceleration etc .. I plugged another PC into the BenQ and the problem persisted.
