Multiple LUTs possible on HD Graphics 3000 card?

I tried to ask this (what I thought was a simple question about the specs of my graphics card) directly to Intel via a support ticket, but they told me to go to the forums and fill out this form. Actually they told me to add it to a particular thread that they thought was the same as my issue, but that was completely unrelated (different graphics card, single monitor, different question), so I'm going to start a new thread instead.

The question is simple - the form below and the attachments are almost certainly way overkill. The question: Does the Intel HD Graphics 3000 card support multiple LUTs? If so, how many (just two, or can it do three)?

A video showing the three monitors can be viewed at: https://youtu.be/wgo4ghQtYmA Spyder5Express calibration woes - YouTube The reason I did it as a video is to also demonstrate the odd behavior after Windows begins to run the monitors (even after only a flicker of interruption). See the description under the video and my audio commentary.

Description

Provide a detailed description of the issue

I use three monitors: the main one on my laptop and two externals. Recently I bought a Datacolor Spyder5Express to try to match the colors on the three screens. The laptop display and the Benq external completed calibration okay and their appearance definitely changed, but the Acer external had an error. Then I noticed that the visual color of the Benq was way off (much bluer) than it should be. When I researched this on the Datacolor website, it says that on Windows, many graphics cards have only one LUT for multiple monitors, and that the only way to know whether my graphics card has one LUT or multiple is to ask the card manufacturer. (If you want to read the whole page that discusses this, go to http://support.datacolor.com/index.php?/Troubleshooter/Step/View/4 http://support.datacolor.com/index.php?/Troubleshooter/Step/View/4 and select the last question choice.) So, what can you tell me about this graphics card and LUTs? Does it matter that I'm using HDMI and USB? (This laptop doesn't have a VGA port.)

Does it fail every single time, or only sometimes?

 

If you can offer a % rate please do.

Every single time. Currently I'm not even using the new ICC profile for the Benq because it looks so bad.

Hardware (HW)

Brand and Model of the system.

Acer Aspire M3-581T

Hybrid or switchable graphics system?

 

ie Does it have AMD or NV graphics too?

No

Make and model of any Displays that are used to see the issue (see note2 below). 

LFP = Local Flat Panel (Laptop panel)

 

EFP = External Flat Panel (Monitor you plug in)

1. LFP (I don't know the model)

2. EFP Benq ET-0006B (connected by HDMI->DVI cable)

3. EFP Acer X191 (connected by USB3->DGA converter)

Re: Multiple LUTs possible on HD Graphics 3000 card?

In regard to your first question (The question: Does the Intel HD Graphics 3000 card support multiple LUTs? If so, how many (just two, or can it do three?) I would need to confirm it with the engineering department.

Your graphics controller does not support 3-display configuration, note the picture below;

Somehow your computer is able to support this configuration but from our end this is not supported.

Now, in regard to your question "Does it matter that I'm using HDMI and USB?" Bear in mind that USB->VGA configuration is not supported in fact every monitor's timings and resolutions are different. When you connect or disconnect a monitor from your computer, the resolutions can change based on the configuration. You are using an unsupported configuration this could be the reason why you are not able to calibrate the screens. Have you tried calibrating one external monitor through HDMI?

Re: Multiple LUTs possible on HD Graphics 3000 card?

Thank you for your reply.

Your graphics controller does not support 3-display configuration...

Does that mean that it does support two displays with independent calibrations (LUTs)? I'm not asking whether a second monitor can simply be connected and sent a signal - I know it can do that. I'm asking whether calibration data for two different displays can be handled by the card. Please read the FAQ on the DataColor site that clarifies while I'm asking this (select the last question on http://support.datacolor.com/index.php?/Troubleshooter/Step/View/4 this page).

Bear in mind that USB->VGA configuration is not supported in fact every monitor's timings and resolutions are different. When you connect or disconnect a monitor from your computer, the resolutions can change based on the configuration.

I know all that - I have been using this setup for two years. Yes, the resolutions are a little different, but I'm used to that (actually, the two externals match pretty well - same size and resolution, and the timing seems okay). I think the http://www.j5create.com/our-products/external-video-adapters-usb3/jua310.html j5create JUA310 adapter is taking care of some of the display management. Anyway, disregard the discussion of the third monitor - let's just talk about the second one.

 

Have you tried calibrating one external monitor through HDMI?

Yes. As I wrote in my first post, the HDMI display did complete the calibration process. But the color of its post-calibration setting was worse than before calibration - it did not look right to my eyes, nor did it resemble the appearance of the laptop display at all. Please see https://youtu.be/wgo4ghQtYmA my video and the color difference will be abundantly obvious.

Re: Multiple LUTs possible on HD Graphics 3000 card?

Hello,

Thank your for your patience.

I have checked with the engineering department and they confirmed that our graphics controller supports a single LUT.
