I've created a photography workstation with the following:
-NEC MultiSync PA241W
For graphics, I'm using the integrated HD Graphics 4000 in the CPU, and am using a Display Port cable. Everything claims to support deep color, but the display drivers only indicate True Color is available (24-bit color depth). How can I enable deep color with HD Graphics 4000?
The following indicates that deep color is supported by HD Graphics 4000:

I am using Windows 8 Pro x64 with 8GB RAM, and have specified in the BIOS to use 1 GB RAM as graphics memory. I do have all the latest graphics drivers and firmware.
Deep color is a feature that comes embedded on the chipset, which means that once you installed the graphics driver that setting will be available by default.
There is no option on the graphics controller panel that allows you to enable or disable this feature.
Regarding the color depth setting, on the display tab, I am just getting 16 and 32 bit options.
Just in case, the following link will provide you the latest graphics drivers.
I have tried to get deep colour working with two configurations that are supposed to be supported and not had any success. I have used a mobile i3 with HD Graphics 3000 and Mini-DisplayPort out to a Dell U2410 monitor. I have also tried a desktop i5 with HD Graphics 2500 and HDMI to the same monitor.
I have confirmed separately (using a FirePro GPU) that this monitor does support 10-bit/deep colour.
In neither case does the driver provide any option to enable deep colour or to change the colour depth beyond 32 bits. Yet multiple pieces of Intel documentation claim both the HD Graphics 2500 and 3000 units support Clear Video HD, and thus deep colour. I have looked through the Windows display configuration options, through the Intel utility (on the latest driver version available on for each of the two CPUs tested), and looked through the custom resolution options.
If deep colour is indeed supported in the driver, please provide step-by-step instructions to enable it and show that it is enabled. At this moment, deep colour support in the chip is useless as there is no evidence the driver supports it at all. You have said that "once you installed the graphics driver that setting will be available by default." Where can I look on my system to see this setting?
Thanks in advance for your help,
There are not settings within the graphic control panel, to change the color deep. That feature is available by default.
There is an option for color depth on the Intel HD graphics control panel, which allows you to choose between 16 bit and 32bit. The onboard graphics controller you have, does not support color depth beyond 32 bits.
I have a PC with the Intel DB75EN motherboard and the i3-3220 chipset. I am planning to use integrated HD Graphics 2500 to run a monitor with 10-bit/color depth (also known as 30-bit color or Deep Color),
with 1,07 billion colors/per sub-pixel. Will it work properly as promised?
Usually intel HD Graphics run at 8-bit/color depth, with 16,7 million colors/per sub-pixel.
This site below and previous replies (Jonathan J and RyanW) says that intel HD Graphics do not support 10-bit/color depth:
In the last comment you said that
"The onboard graphics controller you have, does not support color depth beyond 32 bits."
but what do you mean by saing that?
If you cannot answer to this specific question, please redirect this problem to an computer specialist!
Thanks in advance for your help,
According to engineering we know that Color Depth is also known as bit depth.
Regarding the 10-bit/color depth, I'm going to check with engineering again if this is supported or not.
About my comment "The onboard graphics controller you have, does not support color depth beyond 32 bits." I meant saying that color depth supports 8, 16 and 32 Bits only. Sorry I wasn't clear enough.
Thank you for your kind reply.
I will correct myself saying that I ment: will the HD2500 or HD4000 Graphics support 10 bit per color or 30 bit per pixel?
I look forward for your reply after talk with your engineers.
Thank you in advance and wish you a good day
The answer in specifications for Intel desktop boards built on H77 Express chipset family.
My DH77DF board that support 3rd generation Intel® Core™ processors in the LGA1155 package with Intel® HD Graphics 4000/2500 graphics (http://ark.intel.com/products/family/65504/3rd-Generation-Intel-Core-i5-Processors# @Desktop http://ark.intel.com/products/family/65504/3rd-Generation-Intel-Core-i5-Processors# @Desktop) have following specification for display interfaces:
page 27 in attached document.
DisplayPort's maximum supported display resolution is 2560 x 1600 at 60 Hz at 10bpc refresh with a 16:10 aspect ratio (WQXGA). The maximum bandwidth is 8.64 Gb/s.
Also HDMI v1.4a supported that also have 24,30,36,48 bits (i.e. 8,10 or 16 per each color).
