> 24bit color on Windows???

[kick]

Is it possible to use 30-bit (R10G10B10) color mode or higher in Windows (XP) for the desktop and apps with the current generation of video cards?
How come I can only set 24bit max. even if my video card supports higher bit depths?
The so-called 32-bit color mode is still 24bit (8bits per component plus 8bits for transparency)
The latest graphics cards support 10bit and even 12bit color output (deep color)
Is this feature only available with Windows Vista?
I remember reading how even older-gen nVidia GeForce cards supported 48-bit color (32-bit + 12 for alpha) on Windows (XP) at the time.

Is this mode only available for users of deep color LCD displays or does it work with old CRTs as well?
I remember CRT monitors were not limited and could support any color bitdepth higher than 8 bits per component.

As if you could see more than 15 million colours to begin with.

I wouldn't underestimate the human eye. :p Color banding is still visible in some cases, even in 32 bit.

That said, of course most images are only 24 bit to begin with, so a higher desktop setting would not help at all...

[neo_bahamut1985]

Some programs don't working properly in 24-bit anyway, right?

[funkyass]

chances are you card doesn't support it. its only 32 bit because its word aligned, which makes things a bit faster.Its still only 8-bit per channel- you are seeing as much colour as anyone else.

Ok, let me rephrase.

AS IF YOU COULD SEE MORE THAN 100 MILLION COLOURS TO BEGIN WITH, AND THAT'S ALREADY ACHIEVED WITH 27 BITS, FAGGOT.
Disclaimer: the faggot part was not aimed at blackmyst, which is a great, not faggot guy who happened to defend a faggot this time.
Also it is not related in the least to the OP's sexual orientation, which I don't give a rat's ass about.
Better ?


Anyone claiming they need 30bpp (or more) will get their eyeballs extracted with rusty nails, then surgically regrafted without anaesthetics, repeatedly for some hours.

[Deathlike2]

It's the same logic with 96Khz audio support. Seriously, the imagination is inventing shit.

[Tallgeese]

...Actually, isn't our limit in best conditions and assuming decent eyes about 10 million?

I mean, in theory, simply do enough discrimination tests and you're done, no?

[funkyass]

some cards only support more than 8-bpp for internal 3d rendering.

[Rashidi]

ah, this topic reminds me about the old univbe/scitech DD

Hey dude, your card only support 6-bit DAC, not the latest 8-bit DAC

just replace 6 with 8, 8 with 10, (card with OS if needed), ....

Seriously, if you have an LCD, it DOESN'T MATTER if your video card can do > 24-bit color. Your LCD can't.

Hell, depending on which LCD you may have, you might not even be able to GET 24-bit color. Lot of the older ones only did 6 bits per channel, capping the useful color depth at 18-bit(And good luck getting a video card to feed it that. Hello, banding issues.)

Edit: dear Gil, please upgrade your tag bork detection drivers.

Who said we really need >24-bit color depth? I was only asking whether this 'feature' can be enabled with the current-generation videocards or not.
It's not about the human eye and how many colors the human eye can perceive,but about a company that claims having a feature that can't be enabled at all.It's like what Creative did with the first generation of Audigy cards - 24-bit my ass

Higher color depths are really useful for higher precision of internal computations,though.
A 10-bit DAC is needed to get full 8-bit color output without dithering.
Current videocards have even higher-quality DACs.

What we really need is extending the color gamut of today's monitors,not the amount of gradients that can be displayed in the same,already limited colorspace.
That's why I can't replicate the color of a monochrome Game Boy screen,for example even on the highest quality CRT display with 24-bit color.Those colors just aren't there in the sRGB colorspace.

You have a very wild imagination my friend.

Not 96kHz,but more like 32-bit audio,LOL.

We are still limited by the color gamut of current monitors though.This parameter corresponds to the frequency range in the audio world.With our high-quality LCDs now we have a frequency range analogous to the frequency range of the shittiest brand of cassette tape.
CRTs fare a bit better,but they're still bad.

well, you could try this approach, get yourself a goot web-cam (or camera, something similar), take a screenshot that gameboy, open photoshop, check for color-picker tools, you know the rest...

That's what they want you to think ! Don't you realise soylent green is SPAAARTAAAAAAA

You have a very wild imagination my friend.

And yet I can't quite imagine how I ended up being your friend. Weird huh ?

[Tallgeese]

Black hole. Caused a temporary flux in space-time, causing dimensions to temporarily flip against alternates at specific points.

In this alternate dimension, you are anti-Japanese and such.

There are TFT monitors that can display a much larger gamut than the sRGB colorspace, covering 100% of AdobeRGB (1998) and then some. This is better than any CRT available today. Unfortunately, consumer versions are just becoming mainstream and aren't well designed, for example most of them have internal 8-bit look-up tables, which implies that if any shifts are done to their native contrast response (i.e., gamma & contrast adjustment), a break in the linearity of the represented ramps results, leading to tone clipping and color banding, which is clearly visible, and this is often the case as their color response does not correspond to the standard values, requiring calibration for proper representation. In fact, I can go as far as to say that with really wide gamut monitors a greater color precision is needed, as the gaps between discrete tones become bigger if 8-bit precision is retained.

Whoa, dude, my display shows all colors in the image above! I must have an awesome 1!!!!!

That was unneeded, you understand perfectly what I am talking about.
