    Intel HD 4000 VGA,VGA full range RGB

    JakubJ

      Hi, I have i big question. I read a lot of topic an discuss about Intel and full range settting for video output in 0-255 RGB. I tried edid modification, registry modification, but nothing works.

      So what I am asking for..

       

      I have notebook with two video outputs VGA and HDMI. Notebook display is disabled now. I have two exactly same monitors Dell U2414H. Both connected by HDMI, but from VGA output is used simply VGA-to-HDMI digitizer. Everything for good, pc detect from HDMI output exactly Dell monitor (as digital TV), but from VGA it detects firstly digitizer like Monitor VGA to HDMI (Generic PNP display). (I tried to use exactly display driver of Dell U2414H for this vga output display, but not work.

       

      Problem is that monitor throught HDMI is working properly in full range RGB 0-255, by madVR levels tweaker. But display througt VGA not, it it visible that is limited range 16-235. I would like to help how to get into working state, that both video outputs will work in full range RGB 0-255.

       

      Adapter VGA to HDMI supports HDCP, resolution up to 1080p.

       

      Maybe it is problem by Intel drivers, but it should be good to solve it.

       

      Intel driver is latest 15.33.39.4276 (10.18.10.4276). Windows 10 x64, graphics Intel HD 4000.

       

      Thanks in advance, I hope that community will help me and also to other peoples which have same problem.

            Still nobody does not know? I know that problem with drivers are in big amount, but I am not developer so I do not see inside the drivers perfectly.

              Hello, JakubJ:

               

              Bear in mind that VGA adapters are not supported, Intel always recommends to use straight connections. Note that you are using an adapter to convert an analog signal to a digital one, when converting this signal you might be losing the chance for the VGA to recognize T.V properly.

               

              Regards,

               

              Amy.

                Thank you. Yes.

                But why drivers are sending to VGA port limited range of RGB? My point is not to recognize monitor like digital TV, but set color to full RGB space.

                I can use DisplayLink adapter, but it is not good solution, so VGa apdter works very well, but Intel driver send incorrect RGB range).

                 

                So I am asking if is some unusual way how to change the signal format.

                  You should have full range RGB on VGA but with straight connections.

                   

                  For further reference go to How to get Full Range RGB from Intel HD Graphics? post #60.

                    Yes Amy, this works very well and I tried it earlier, but RGB for normal desktop mode not. There is visible limited range.

                    VGA is connected throught adapter.

                      Have you check with straight connections(VGA-VGA)? Like mentioned before VGA adapters are not supported from our end.

                        Dell U2414H has no option for VGA - only HDMI, displayport.. But when I connected another monitor (older) VGA-VGA, then it is probably ok/same view, because that monitor is not IPS and black is not exactly black. So I cannot recognise if it is FullRGB.

                          Amy_Intel

                          I understand but from our documentation full range RGB is supported with straight connections, we cannot confirm that you will get full range since you are using an unsupported adapter.
