Does my 6970 support deep color (10bit) over DP?

post #1 of 8
Thread Starter 
title says it all


I was reading a review of my u3011 and one thing it mentioned was "one more pertinent limitation is from a display point of view, where there must be an interface which can support 10-bit colour depth. At the moment DisplayPort is the only option which can. It is provided here, but a full 10-bit work flow is still extremely uncommon in the current market."

Im hooked up via DP but i didnt know if my card actually supported it?

It should, but don't quote me on that.

If I read correct, you want to access full 10bit color on your monitor. I didn't even know that any Ultra Sharps supported 10bit, and can't get a definite answer on whether or not my U2311H is 6 or 8 bit. So some clarification on this would be nice, but lets answer the OP's question first.

"The Dell U3011 utilises a 10-bit H-IPS panel, capable on paper of producing 1.07 billion colours. The panel itself (reported to be LG.Display's LM300WQ5-SDA1) is listed as a 10-bit panel, but true 10-bit support does require an end to end "10-bit journey". Although we have not 100% verified this, the panel is most likely technically an 8-bit with A-FRC technology, supporting up to 10-bit colour. This would fit in with the U2410 and U2711 models as well. Have a read of this article which discusses it in more detail. It should be noted that the LM300WQ5 was also used in the 3008WFP display as well. This was the LM300WQ5-STA1 revision, which only supported 8-bit colour and a 16.7m colour palette. The panel has been updated for 10-bit colour support and 1.07b colours, and caries with it a new revision number."


and about the u2311H
"The Dell U2311H utilises an e-IPS panel, capable of producing 16.7 million colours. The panel itself actually uses a 6-bit colour depth with advanced frame rate control (A-FRC) to produce the 16.7m colours. This is different to regular 8-bit IPS matrices, but this is likely a measure taken to achieve a lower price point for these so-called e-IPS displays. Originally the panel was listed as true 8-bit based on the manufacturers spec, but studying detailed information from LG.Display's datasheet confirms the panel is in fact 6-bit+AFRC. This review has been updated accordingly in this section."

Judging from this, you probably know a LOT more about these e-IPS and IPS displays than I do. What ever I tell you your probably already know.

Maybe I should mention that the 6970 is a high-end card though, do if that doesn't support 10bit, than I don't know what does.

EDIT: Also, I see you have two U2311H's too, how do they compare to the full IPS of the U3011? Is it as big as the difference between TN and e-IPS/IPS, or greater?

heh, i was impressed as much as going from my TN dells to my u2311H as i was when i stepped up to the u3011, its an amazing screen

they say
"◦HDMI 1.4a with Stereoscopic 3D Frame Packing Format, Deep Color, xvYCC wide gamut support, and high bit-rate audio "

Deep color is 10bit right? but its only supported over HDMI??

Deep color is just a specification of HDMI 1.3 and DisplayPort. You still have to enable 10-bit color through the graphics card control panel. This feature is only available to workstation cards afaik.

Not many people use 10-bit color. It is still fairly rare.
