I hear you, but with contrast ratios coming a long way than what they where. Makes me wonder if industry wise we will see more of a phase out of IPS/PVA panels.
The only thing they are going a long way with regarding contrast ratios on TNs is gimmicks. By that I mean extremely high contrast ratio presets that ruin color accuracy. Hopefully the consumers will get smart, read up on the reviews, see that these DCR TNs aren't what they're advertised to be, and the manufacturers will stop trying to fool everyone.
Samsung is one of the one's jumping on this gimmick bandwagon the most. TNs will never be as good as 8 bit panels, esp a good IPS. Besides 8 bit color depth, IPS panels have horizontally placed crystals with 2 transistors per pixel, there's just no comparison. On the other hand, a decent TN is still pretty good for gaming only use.
