There isnt much backlight bleed I have this somewhat circular shaped discoloring/brighening seen here
Did you get any similar oddities with black screen test on the Acer XF240H?
lol :Y Even on 2000$ TVs we can observe clouding issues etc. It is really hard to evaluate on camera. Hope you will receive a good unit soonand the guy I talked to in the store said that the problem I had is common on the cheaper models since well they're made to be low price models so I guess it was simply bad luck there.
