      The change is needed in the operating system kernel mode graphics driver. Microsoft has now planned this development for a Windows 10 future release.
      In the meantime, provided you have purchased a platform allowing you to, the workaround is to disable the low end GPU so Windows uses the only one left. Today, Windows will always use the POST graphics card.

      @Daniel, you need to create a ticket with the logs (https://support.displaylink.com/knowledgebase/articles/533818-how-can-i-report-windows-issues-to-displaylink). Without data you can only get generic information. GPU works in any case so that message is, at best, misleading. Do you have a support case with DaVinci, if so, when you create your ticket by email with us, give contact details so we can contact DaVinci to understand what they rely on.

      I don't understand the unsupported defamatory accusations from Elrond when transparency has been used from the start.

      Windows uses the POST graphics card. Windows cannot select the POST card. POST is before Windows boots, that's at BIOS level. The OS is getting changed not to always use the POST GPU, and, when the change is done, an indirect display driver will be able to select GPU affinity.
      The GPU setting in the OS is for application rendering rather than display adapters and includes a bug.
      Currently, the work around is to use a direct display (ie. native laptop display) as primary or main display. That means keeping the lid open, for instance. Daniel confirmed that earlier in the comments.
      Unfortunately, very few people took the time to report this issue through the Windows 10 Feedback Hub so we had to wait until a computer manufacturer escalated this so it got prioritised.

      @Phil, this Thunderbolt 3 dock is not using DisplayLink technology.

      Hello,
      @Slava, the thing on the app being started sounds like the old Intel graphics bug on OpenGL pass-through. The GPU used cannot changed at run time. Just use an Intel direct display before starting the app if your machine is below 6th generation. If 6+, get driver from xx.60.xx.xx or xx.65.xx.xx driver where this is fixed.

      @Elrond, @Eugene and others, yes it will. This is now on the roadmap and planned. The OS release it will be in depends on development progress and quality testing. Once I have progress updates and I am allowed to share it, I will.

      @AdamH, because the other option doesn't used the Microsoft IndirectKMD as it's not an indirect display.

      @Jan, you can subscribe to comment notifications, as far as I can see from my end.
      What is a CZ entry? There was a bug report and the rest was during meetings.

      @ckoroglu The issue here is about Windows and their kernel graphics driver. Linux doesn't use Microsoft kernel graphics driver. Linux doesn't have the notion of "indirect displays" either. That's a Windows feature.

      Jan, this report says Windows 8.0 (that's the build 9200). This discussion is about Windows 10 Anniversary Update onwards. If you're really on Windows 10 and the graphics tool reports Windows 8.0, I wouldn't trust it understands how the Anniversary Update graphics subsystem fundamentally changed the deal and how it can measure things properly for something it doesn't understand. If you are really on Windows 8.0, I don't see us doing any new development for it as almost no-one uses that OS (~1% maybe). Could also be the OpenGL bug on the Intel graphics driver affecting your tests.

      Feedback about the OS using the GPU from POST is not a DisplayLink opinion, this is a Microsoft graphics team affirmation. They wrote that part of the feature. I am inclined to believe both the author and general test feedback.

      Hell Jan, how do you check what GPU is used? I am rather inclined to believe Microsoft graphics engineers who told me the kernel driver doesn't change on the fly and that they won't change until they receive feedback from Windows 10 users.

      https://aka.ms/Cojpi9 is a Windows 10 Feedback Hub entry from someone about the graphics card selection for Windows 10 v1709.

      This is an operating system feature. The graphics card used is the POST one. if your Dell 7559 gaming laptop uses the Intel GPU for POST, then Windows will also assign it to indirect displays like DisplayLink.

      Unless you report this to Microsoft for them to change the selection, then I don't foresee any suitable resolution.

      @Manatax, can you use our Customer Support Tool (http://support.displaylink.com/knowledgebase/articles/533818) and that will create a ticket. We would need to find a machine close to yours to see how the disabling works. We can then discuss this with Microsoft.
      Also, please do complain through the Windows 10 Feedback Hub that you want to use your high end graphics card with indirect display because the iGPU is not powerful enough to do <whatyoudo>. We need to send enough feedback for this to get prioritised.

      No Zachary, unfortunately there hasn't been enough feedback through the Windows Feedback Hub to make it a priority for them. At the moment this is scheduled for Redstone 4 but may well be postponed again if customers don't flag this is important.

        Update: November 5th
        Dear DisplayLink macOS users,

        DisplayLink has worked for many months to maintain support for its users during the transition from macOS High Sierra to Mojave. While functionality such as Ethernet and audio or charging, where implemented, is unaffected on all releases, display connectivity has been limited on macOS releases 10.13.4, 10.13.5 and 10.13.6.

        macOS 10.14 Mojave with DisplayLink driver v5.0.1 allows you to run up to 4 extended displays with now optional clamshell and mirror modes. Support for rotated displays is also improved.
        DisplayLink driver v5.0.1 is applicable to macOS 10.14 only.
        Driver v5.0.1: http://www.displaylink.com/downloads/file?id=1257

        Should you experience black extended display(s) with only mouse cursor on 10.14. We recommend you use macOS 10.14.2 Beta 1 or newer. We have also left DisplayLink driver v4.3 Beta available to force an AirPlay extended display on these machines if you cannot update to 10.14.2 Beta 1 with DisplayLink driver 5.0.1.…

        @Mykl: 5.0.0 and 5.0.1 are already supporting those models. The problem is not in the driver. The driver uses an OS API which doesn't care about model/GPU. We have asked for the bug fix to be distributed.

        @TheCork: Apple Watch problem was reported to Apple, as flagged in the dedicated thread (https://support.displaylink.com/forums/287786). Despite reading every single comment, I would tend to reply when there's at least some value in doing so.

        @MarcelTK: We have validated the 2018 model fix and asked for it to be distributed as soon as possible.

        @Lars, that product doesn't include any of our technology. You need to contact Dell.

        Hello, if you have DisplayLink 4.3 beta 5 with Mojave Preview 4 (Beta 5) and are experiencing black external displays with only the mouse cursor even after reinstalling the driver, please create a ticket with your logs as described in https://support.displaylink.com/knowledgebase/articles/755301. We don't have the reproduction internally to analyse yet so logs are necessary to give hints on what could be going wrong.

        Hello David, 4.3 Beta 5 dated 31st May 2018 is the correct driver to use with Mojave preview 5. The build number for 10.14 beta 5 is 18a347e. If you have blank external screens with only a mouse cursor, you are not running the latest Mojave beta as Jan flagged here.

        A full extended display support solution cannot rely on AirPlay which has too many limitations for that.

          There is no trace of any ticket from this email address.
          However, you are correct that if you were inappropriate or insulting, we would have closed your ticket without any reply. Being frustrated, whatever the level, doesn't mean our staff has to be insulted.

          I have renamed the feature for what you wish: enable HDCP playback support on macOS. That type of feature will require collaboration with the OS vendor so we can get access to the encrypted pixels, like we did with Microsoft and Intel for Windows 10. Software vendors also had to follow the OS implementation changes. Then, based on capability reported, the video player decides what it plays, if it plays. For instance today, Netflix lowers the quality for non-protected outputs.
          Finally, it will also require that your hardware supports HDCP. Not all device manufacturers are DCP licensees. Being DCP licensee is a requirement for DisplayLink to be allowed to ship them chips with HDCP keys inside that they can use in their product.

            Firmware update of the DisplayLink chip is non-optional and is happening on all OSes, transparently. It is not possible for the user to change the DisplayLink firmware selectively, even on Windows. You might be referring to other firmware for other technology your product can integrate. We can pass this onto the device manufacturer.

            I can also pass your feedback about Multi Monitor Software to them. This is a third party whose software works with or without DisplayLink technology.

            Which item(s) from DisplayLinkManager are you missing?

              I've renamed the idea to something more meaningful. I have also removed the shouting and the dramatic wrongful direct causality effect. Not having TLS does not mean you get a malware.
              Let's stay factual please rather than building up unhelpful alarmist accusations.

                @Ralph, not for now and it won't be technically possible in all devices. Anyway, the OS doesn't give us HDR pixels today anyway so even if the driver and the chip could do it now, you would still not get HDR on the displays.

                  The new estimate of delivery for f.lux, night mode, and monitor calibration on Windows 10 Creators Update onwards is for release 9.0, planned before the end of 2018. When a 9.0 Alpha or Beta is issued, you will be able to try the feature on products based on the DL-3000, DL-5000 and DL-6000 series ASICs.

                  f.lux has enabled some support for DisplayLink indirect displays (Windows 10)
                  You can download f.lux from https://justgetflux.com/

                  That's correct Gregor. F.lux implemented this on Windows 10.

                  Thank you Anon, but we cannot take any credit. What you have today is all thanks to the F.lux team.

                  @JI, there is a separate thread for Mac and it has different challenges. I have renamed this idea to specifiy Windows.

                  @Anonymous, the Dell D1000 is using the same hardware family (DL-3000/DL-5000) as the Dell D3100 and I have been using f.lux on Windows 10 successfully for weeks. Therefore there is no issue on that side. I have also tried it on the Dell D6000 using the latest DL-6950 chip and it works.
                  I suggest you check f.lux options.

                  F.lux has announced supporting DisplayLink indirect displays with their latest release. I have personally been using it since.

                  @mmm Dell D3100 with Windows 7 is targeted for release 8.3 currently scheduled for July. It's the right hardware, but wrong OS for 8.2 preview.
                  I'm looking at trying to get an *alpha* version of the 8.3 driver in May/June for those who feel like trying unfinished software. Today, it's not been tested enough to be acceptable even as an alpha. When I have news I will post.

                  Because of the issue with gamma tables in the Anniversary Update, we will not be able to enable this feature by default on that OS. Your feedback validates our testing with issue seeing the login screen as Windows may send black gamma tables instead of default which is not acceptable for people who didn't ask for that feature! You can use the current trick from the forums though.
                  Windows 10 Creators Update has the fix so we will enable support by default. Engineering is currently testing on Windows 7 - Windows 10 TH2 (build 10586). If testing goes well, then gamma table will be supported from DisplayLink driver v8.3 on devices whose Hardware ID starts with USB\VID_17e9&PID_43 which is the majority of devices in the field.
                  Devices whose Hardware ID starts with USB\VID_17e9&PID_6 are next in line but we have already identified restrictions on HDMI during feasibility study.
                  Devices whose Hardware ID starts with USB\VID_17e9&PID_FF will come later.
                  Devices whose Hardware ID starts with USB\VID_17e9&PID_0 and USB\VID_17e9&PID_40 cannot have new features added once they are in the field so will not get new features.

                  @Henrik, best channel is here. When ready I will communicate how to try for those who want and have the adequate hardware and OS. I'll probably open a new forum board for the colour correction feedback on Windows. Testing will tell me when it's ready.

                  Hello Piotr, our Mac team is starting evaluating if it possible. We have met issues with another part on Mac (DDC/CI) so this is not a straight forward port from Windows.

                  Hello Sven, very nice monitor, I use it for trade shows as it's light. This device will not be supported in the initial version version. We are still unsure about possibility. They are built differently and already have gamma curve tables which manufacturers like Asus would use to calibrate them in factory depending on panel used. We need to see if we can override the feature. Investigating is definitely planned.

                  @johan and all. The products which will first be supported have their hardware ID starting with USB\VID_17e9&PID_43. You can get the hardware ID from Device Manager in the device details (see how to find the HWID in http://support.displaylink.com/knowledgebase/articles/544834#otherdevices).
                  Once I have a development build, I will probably create a forum board.

                  It's not been "planned" for two years Rowen...

                  Brian,

                  TL;DR: It's a big job and we don't do hack jobs so it takes time.

                  Details:
                  f.lux support is under analysis. This requires extensive firmware and some host software work.
                  There are 10s of millions of devices in the field with a bit more than one version of Windows, some with one display, some with two, some with three... Some with HDMI, VGA, DisplayPort, DVI, and a combination of everything.
                  Today, we do not modify the image in any way, we take the output of the graphics card. This is brand new feature that is requested, not just a tweak. This new feature MUST NOT, in any way, create issues when not in use (so in most cases). We need to setup brand new test rigs and test suite to defend it.

                  I have deleted injurious comments from Marek Ziel (Apsik).

                  @All. f.lux support is under analysis. We met with the f.lux developers to discuss an implementation which will keep working with new versions of f.lux.
                  We are trying to think about to support individual colour correction rather than just an identical gamma curve change applied to all displays. However, we don't yet if it is possible.

                  @Andrew. DDC/CI pass-through on DL-3000 and DL-5000 was released as part of 8.0 M0 so has been available already.

                  @Viking, you do not need f.lux to change brightness. You can use Screenbright, a free utility which is already supported across all recent docking stations with DisplayLink technology.

                  @Sergio, the comment about Windows 10 is not about applicability of the solution, but the reason for not having implemented it yet.

                  The flickering on Anniversary Update is a f.lux bug they are aware of and are working on. Please look for new versions of f.lux.

                  Felix, colour correction and contrast are different. From our 8.0 Beta 4, you are able to use applications like ScreenBright to change the contrast settings via the computer.

                  Colour correction is totally different, as f.lux states in their online contributions. The feature is currently on the roadmap for the devices which have the horsepower to handle it. Device with a USB Product ID starting with 0x0 will never be able to support it because, unlike brightness or contrast which are just a command to send, colour correction requires the device to compute.
