    Many 1520/1720 owners say that unlike xx05 series (wich had 8bit-16million colors), their screen (6bit- 260k colors)is grainy due to dithering issue(emulation of 8bit color palete) . What about wuxga screen in 1720? is that one also have grain issue? is it much worse then the older one in 1705 which was awesome (almost 600:1 contrast, 240cd/m2 brightness and deep black) ? Does it make sense to stay with standard xga screen and buy the OLD wuxga on ebay to replace it by myself?

    260K are you sure? Not enough colors will not look good, I can't believe.

    Most notebook displays (aside from a few that have IPS displays, like the T60 with Flexview and the ASUS V6) are all 6-bit TN displays.

    If anyone told you otherwise, they misunderstood. 6-bit panels are capable of producing 16.2 million colors with dithering as opposed to 8-bit panels 16.7 million colors. There will be a difference for graphics design and that field, where color reproduction is key, but for most users, it won't matter.

    Apple had some class action suit against them on this same issue. In short, NO laptop manufacturer says their screens are 6-bit per channel, even if it is. You will never see it. Everyone everywhere claims 24-bit (8-bit) 16.7 million colors, because that's what the graphics chip outputs.

    Many manufacturers are prone to mislabel their displays at 16.7 million colors - it happens even with desktop displays, but one thing they usually don't mislabel is the viewing angles. Anything less than 170-178 degrees is indicative of a non-MVA/PVA/IPS display.

    In this case, the xx05 series, I'm certain they're got the colors wrong.
