I just picked up a Sony Vaio duo yesterday. However, I have found that it probably has a defective screen.
It is a 1080p IPS lcd, but the issue is, when I display solid colors, I can see noticeable wave like screen flickering, like what you would see if you were shacking an LCD or rapidly softly tapping an lcd. However, when I change the refresh rate to 40hz (the only other option besides 60), the flickering noticeably disappears.
I'm probably taking the unit back, but does anyone have a possible cause any ideas on why this happens
