HELP NEEDED - What colour depth will a geforce gt 230m support?

Don't all of these cards now support 32 bit color?

The name "32bit" is misleading I believe. Generally the highest bit (colour depth) used is 10, which produces over a billion possible colours, compared to 8 bit which produces 16.7 million. So as you can see there is a bit of a difference.

That's the jist I got from online research.

I am pretty sure the only NVIDIA cards to support 10bit are QUADROS, not GeForce unfortunately.

Please correct me if I am mistaken.

It's 8 bits per channel (RGB and alpha). 8x4 = 32 bits. So yea, it won't support more.

Oh right, yeah. I suppose this adds to the debate over GTX vs QUADRO for a workstation. An 8 bit IPS is still going to be great compared to a TN, but if you are doing film grade stuff then you need a QUADRO or similar to achieve a billion+ colours.

It's frustrating because I suspect that again, the GTX are up to the task but drivers not optimised for this.

Has anyone heard of a driver hack to get 10bit on a GeForce card?

Thanks guys, I think I'm going to order the PA246Q anyway.
