LG Flatron L226WTQ-xF 1.80 - minimize ghosting
Someone asked me what he should do if he has ghosting with that screen (didn’t have original bill). I told him to call service hotline and try them to replace the LCD. What was surprising me… They told him that they don’t replace those sreens anymore but gave him the tipp to set panel in service menu to LPL22W 4LG and set aging on. He tried this some hours with different games and the the result was quite ok - nearly no ghosting 
I did not verify this on my own, but i think worth to mention. If you want to try it and it’s working, leave a comment
