Does anyone know what type of Panel the Vaio Z 1080p is?

Like with most things, I believe it when I see it.

- TN displays have, for a decade or so, been 6-bit or less. Partially because it cuts cost, but also because 6-bit displays have a quarter of the reaction time of 8-bit displays (a 4 ms 6-bit display would be 16 ms if going 8-bit).
- Most consumers do not even know that their 6-bit displays only display ~262,000 colours, dithered. Why give them more, when they accept and even praise what they have?
- There are precedents for corporate marketing calling a 6-bit physical displays "8-bit", because they use 8-bit (or higher) drivers.

I think it's up to those who sell displays to unambiguously state the technology used, when it really differs and is a marketing advantage.

When they don't, I choose not to believe it until it has been independently verified. Until then, I will treat these as 6-bit TN displays with 8-bit drivers, and make sure I get an IPS display if I want an 8-bit display.

 

Well, IPS isn't the only type of non-TN display, so if 8-bit is the only requirement you still have other alternatives. Granted, IPS is often considered the best quality, but there are areas where IPS loses out to other panel types.
