    Multiple LUTs possible on HD Graphics 3000 card?

    OsakaWebbie

      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: 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 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)

      How much memory [RAM] in the system (see note2 below).

      4 GB

      Provide any other hardware needed to replicate the issue.
      ie: Cables&brand, cable type [vga, hdmi, DP, etc], dock, dongles/adapters, etc

      j5create USB->VGA converter

      HDMI->DVI cable (unknown brand - I'm sure this doesn't matter)

      Hardware Stepping (see note1 below).

      Hardware IDs screenshot attached.

      Software (SW)

      Operating System version (see note2 below).

      Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.151019-1254)

      VBIOS (video BIOS) version. This can be found in “information page” of CUI (right click on Desktop and select “Graphics Properties”.

      I didn't find anything about Video BIOS in there, but hopefully it's in one of the attached files as well.

      Graphics Driver version; for both integrated Intel and 3rd party vendors (see note2 below).

      Presumably somewhere in the attached files

      SW or Apps version used to replicate the issue.

      Spyder5Express 5.0

      Configurations

      Single display, clone, or extended (see note2 below).

      Extended

      Display resolution & refresh rate setting of each display (see note2 below).

      In the attached DxDiag.txt

      AC or DC mode, i.e. is power cable plugged in or not?

      AC

      How to repro

      Please provide steps to replicate the issue.  These steps are very crucial to finding the root cause and fix.
      A screenshot to illustrate the issue is a huge plus. A video of the failure is even better! Attach to the post or provide the YouTube link.

      1. Use Spyder5Express to calibrate the LFP. (The Express software does not have any options or settings - you just run it and do what it says.)
      2. Use Spyder5Express to calibrate the Benq EFP.
      3. Use Spyder5Express to attempt to calibrate the Acer EFP. (error occurs most of the way through the calibration process)
      4. Look at the resulting colors of the laptop and Benq, and cringe at the Benq.
