Horizontal lines across screen with it enabled. Very small, but noticable on black/grey.
And bluish tint on black/dark shades of grey.
With/Without BBR enabled.
Is this normal? Is it possible to reduce the lines atleast?
VT trick - Horizontal Lines?

Re: VT trick - Horizontal Lines?
Yeah it's normal.
It happens when you accelerate the scanout of the panel. The panel is basically being run 'out' of specification (there should be no life degradation from this, just 2d image quality reduction)
Lightboost has the SAME horizontal lines, just even more intense (if you unlock lightboost mode on your monitor--if you have an Nvidia card, you should be able to see them). Lightboost horizontal lines are more intense because the scanout is accelerated by the LC panel (I think Chief said the data is fed to the panel and then outputted at once)--it's like using a VT tweak in a way, but without using a VT tweak (trying a VT tweak on a VG248QE in lightboost mode will keep lightboost at 1175 VT @ 120hz, but the monitor black screens wit out of range at 1200 VT). On a Benq, you still get lightboost at 1175 VT (if unlocked previously), at 1200 VT, you don't get lightboost and you get an "out of range" signal, BUT unlike the VG248QE, you still get a picture on the screen, although it's massively 'stuttering' screen (since the Benq is designed to use high VT's), even if blur reduction is NOT enabled. Also stutters at 1250 VT, and you no longer get the out of range OSD popup. It cleans up at 1300 VT though.
