    I see that the 1920x1080 screen option on the VAIO Z gives 96% adobe gamut, so how much does the 16x9 display have?

    thanks

    If you have the computer on you, you check what screen is used and search for a datasheet.

    In the Hong Kong website the VPCZ135GG (with 1600x900 display) states that it covers 100% NTSC color coverage, but there's no mention about the Adobe RGB. The VPCZ138GG/VPCZ139GG with the 1080p display both mention about having 96% Adobe RGB coverage. I guess it's somewhat less (certainly not equal to) than the 1080p since if it were the same it would've been advertised the same as well.

    The NTSC and AdobeRGB gamuts are almost identical -- the NTSC one has slightly more reds, while AdobeRGB supports slightly more blues.

    That said, the "100% coverage" is meaningless in practice, because it's a 6-bit display that can only display 262144 distinct colours, some of which will be outside this gamut (plus dithered approximations of other colours).
    Also, "100%" is open to interpretation -- it can mean 100% of the area, i.e. that the gamut should be at least as large, which qualifies even if it's skewed and a large part of the reds, for example, can't be shown.
