Thanks for the details. If I'm not doing anything that requires exact and precise color reproduction like photography or graphic design, would the L220x be better? I just want a monitor where HD movies and gaming look very good. Aside from these, I'll just be doing normal computer tasks like internet, word processing, etc.
Personally I find the glow less bothersome than the PVA shift. YMMV. The PVA shift actually changes the level of revealed details and leads to all kinds of unexpected issues. I get sort of dizzy/headache like symptoms from PVAs false 3d effects. The glow is more like an overlay on a stable image, I might not like it when I see it, but it causes no real issues.
Though right now, I don't have either, but if I had to choose, I would clearly go with glow before shift.
