A few hours after installing and using the (quite heavy) Wacom Cintiq 27QHD, I noticed a faint blueish blot/bubble right in the middle where the Cintiq was attached to the LX HD Sit-Stand.
It spanned half the width of the entire screen. I took it down and laid it on my desk. The day after I checked again, and it seems to be gone now.
Most likely the blot was caused by the layers (LCD > touchscreen mesh > glass plate) separating (I'm also posting this on the Wacom forum to find out if it might be faulty equipment).
I was wondering if anyone here has ever had a similar experience/fix?
