Photoshop 10bit support

[Guest]

Hello!

There are 16 and 32bit modes in PS, so my question is: can PS display 10bit color depth per channel if all other components support it? (i.e. Windows 7, ATI FirePro graphics card,10bit monitor connected via Displayport)

If not, will there be an update/plugin? Will the next version of PS support it?

I'm thinking about upgrading. Wouldn't make much sense if the software doesn't support it…

Thanks in advance

Haven't some folks been able to use Aero and 10 bit color at the same time with nVidia?  Seems I've read that somewhere.  Have you tried it?

With my AMD card, there is a specific setting in the graphics card driver to enable 10 bit output.  Once enabled, you need to reboot and Windows automatically disables Aero.  There is no need to disable Aero manually.  This is also true of other video/graphics changes which are incompatible with Aero, which is that Windows disables Aero automatically.

I didn't see where you mentioned changing a setting in your display driver to enable 10 bit.  If you haven't tried that then look at all the settings in the display driver for your card.  And I just noticed Chris Cox mentioned this already with the "Deep Color" setting.

first off: thanks for everyones help!

second: i havent tried switching aero ON before. just did it now including reboot, but same as with aero off.

the deep color option is from an older driver. according to support from my manufacturer and nvidia the 30-bit signal will be activated automatically via displayport if a 30-bit screen is detected.

there is an option called "force 10-bit per component" in the newer driver, but that doesn't change anything. and support told me not to switch it on.

so maybe the screen isn't recognized as 30-bit capable (which the manufacturer of the screen tells me it is).

[Chris Cox]

NVidia should have some diagnostic tools to tell if the display is detected as 10 bit capable (and, of course, that only works with displayport, not DVI).

I don't know the protocol they use to determine this, but suspect it's another EDID result. If so, you might be able to use an EDID utility to display those results yourself.  ( http://en.wikipedia.org/wiki/Extended_display_identification_data )

this tool http://www.entechtaiwan.com/util/moninfo.shtm tells me "Color bit depth.......... Undefined" for both of my monitors. the 8bpc and the supposedly 10bpc.

i will try and connect the supports of the two companies.

[Noel Carboni]

Thanks for the link to that little handy utility.

For what it's worth, it reports "Undefined" as well for both of my (circa 2004 Dell 2001FP) LCD monitors (which I know are 8 bits/channel).

Quato is working on high priority to solve this problem. As soon I have a result I will tell.

[gggmmm]

Quato fixed my monitor... but 10bpc output still doesn't work.

i sent in my monitor and got it back recently. apparently they updated the EDID file, because the monitor-tool now diagnoses 10bpc color depth and the NVidia driver now shows the "deep color for 3D applications"-option, which it hasn't shown before. but i still see banding in the ramp file (which of course disappears, when i change bit depth from 16 to 8). i contacted PNY support again, but so far no answer.

so my still not working setup:

- 10 bit monitor: quato 240 LED, hardware calibrated, diagnosed with bitdepth 10

- 10 bit graphics-card: nvidia quadro 600

- PS CS 6 with "30 bit display" enabled in the advanced graphics processor settings

- win 7 64 with aero disabled

and the testramp still shows banding.

[gggmmm]

in the end my Quato went out of business for health reasons and my dealer took the monitor back, with me loosing some money and lots of time. i now have a NEC monitor, which works perfectly with ten bit, is 27" instead of 24" and cost about half the price.

[mdb-at]

Thanks’ all for advise!

We will get a solution, because Quato Intelli Proof 240 LED excellence ist a high end product.

My mail sent to Quato (translated):

"PNY-Support wrote:

it seems Quato 240 LED don't tell in EDID block that he knows 10 bit. Result is that the Quadro don't switch to 10 bit.

Ask Quato for update of the EDID block.

If you ask for EDID block of Quato 240 with Monitor Asset Tool vonentechtaiwan.com, coulor depth will be unknown and not 8bit or 10 bit.

Mit freundlichen Grüßen/Best Regards

Ihr/Your PNY Support Team

Now I wait for answer of Quato.

I tell if I get any news.

Back to the drawing boards!

[Hudechrome]

Thanks! I don't know what was wrong, however!

It's one of the priciest ones out there.

Hi,

Just register to ask, is it possible for ps to use d3d than opengl 10bit buffer? It's just painful to play on one machine and do editing on another one and switch monitor input back and forth.

[Gianluke]

Hi everybody. I have Ati FireProV3800 and NEC PA271W with Display Port. I cant' see 10 bit in PS Cs5. ramp.psd appears with banding in PS. I have last driver update of Ati and Adobe. I set right setting in the driver and in PS. I installed again Windows 7 x64 a few weeks ago but I still cannot see any way 10 bit. I tried Nec 10bit application. It works when 10 bit is enabled but two windows (8 bit and 10 bit) appears equal. I cannot see any differences. What else can I do? When I bought Monitor and Ati card (October 2010) I tried and it worked in 10 bit. After 2-3 months no more.

[Gianluke]

Finally in CS6 Beta there is a 30 bit Display option and now it works fine.

[Chris Cox]

Previously it was dependent on the driver, now we enable it and offer a way to turn it off.

Unfortunately Apple has indicated that they have no plans to support higher bit depth displays.

[Gianluke]

Yes but you must enable it in the driver too. Now It doesn't work just PS enable.

[Gianluke]

Is normal to see 10 bit in CS6 just when any windows is open? If I open a Levels windows 10 bit mode disappears.

[Yahor Shumski]

It seems Adobe finally solved 10-bit related problems with the latest release of Photoshop (2015.1). Both for Mac and PC

[D Fosse]

Have you tested it yourself?

I'm ready to pull the trigger on a new video card if it now works reliably. Otherwise I won't bother.

[Yahor Shumski]

Test gradient image finally looks smooth for me (Photoshop 2015.1, Quadro K620 graphics, Windows 7). It is also smooth in Moonlight Develop mode.

But I read about the same smooth gradient on 8-bit displays rising the question if Adobe just add dither to video output.

[D Fosse]

Ah yes, could well be.

I see that on the Mac side - the word is that the latest OS X version "quietly" added 10 bit support - people even claim Lightroom now displays without banding. But there's no 10 bit support in Lightroom on either platform.

[Yahor Shumski]

An update here.

I have two monitors side by side. NEC PA272W (10-bit) and 2090UXi (8-bit).

In Photoshop I see banding on 8-bit monitor and none on another one. So 10-bit pipeline works as expected here.

However behavior in Lightroom is different, the gradient is smooth on every monitor rising questions about dither in use.

[Gianluke]

For me it still doesn't work. Photoshop CC 2015.1, Windows 10 x64, AMD FirePro V3800. I see banding in ramp.psd

[Yahor Shumski]

Do you have 30-bit display setting checked in Photoshop?

In previous version for me banding disappeared in Proof colors mode. Please check this option too
