Hi everyone,

A bit of an emergency, I was about to order a ASUS PA246Q IPS for a friend for image editing work.

The problem is, I am told that this graphics card (geforce gt 230m) will not produce 10bit colour, even through Displayport.

Is this correct?

If so, do you think the card could produce 8bit, alternatively?

Personal expreience would be best.

Thanks.

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.
