Colour bit depth only 16M

[fefrie]

Just happened to see it on the lenovo website?

I just use the lcd in the lid, never plug it into an external lcd.

If 16m is the max, might as well set the settings to 16m right?

What are you referring to????

[fefrie]

Display property settings where you set the screen resolution size etc.

[ajkula66]

You must have the incorrect driver installed.

32-bit is a norm for ThinkPads and has been for at least a decade...

What machine are we discussing here?

I've got a t42.

I'm certain that if you go into the Display Properties (presuming a correct driver is installed) you will find a 32-bit option...

@op...

"32bit" is 16 million colors. 24 bits for actual color info (16,777,216) plus 8 bits for an "alpha channel" (whatever that is).

32/24 bits color depths for laptops is mostly a lie. A few laptop panels at 8 bit per color has recently appeared, but otherwise 99% ogf all panels are 6 bit per color or 18 bit in total. All panels will accept a 24 bit (8 bit per color) input, but will just discard the two least significant bits. Running at 16 bits means 4 bits per color + 4 bits alpha channel, i.e. you'll lose two bits per color, or 47 extra shades of each color (!). So just select 24 bits in windows and everything will be fine
