    I installed all graphics card drivers.
    What is the minimum OpenGL for QT to work?

    Hi
    seems to be 2.1
    http://doc.qt.io/qt-5/windows-requirements.html

    Can you test with anything else than Qt if openGL works?

      The program "OpenGL Extension Viewer" says that OpenGL 2.1 works.

            Hi
            Is the Radeon Xpress 1150 the only graphics card there is?
            i mean laptop do not have other one?

            For some reason Qt do not like the openGL, it seems.

            Do you need to use QML ?

                Hi
                Please see here
                http://www.sanchitkarve.com/blog/category/how-tos/
                section
                Use ATI Radeon Xpress 1150 Graphics on Windows 7
                says "Moral of the story: DO NOT install version 8.593.100.0 !!!"
                which might be the version you have ?

                I would try an older driver like mentioned in the article.

                  But the test shows that the driver is working fine.
                  Surely other tests will show that the driver is working.
                  The point does not seem to be in the driver.

                    Hi
                    Did you try to run a game or anything that needs good
                    acceleration?

                    It seems Qt (QML) cannot create a context so something is not
                    working as expected.

                      I did not run the games.
                      But what then are the minimum requirements for Qt?

                        Well, link says openGL 2.1 but is a bit vague on shader model and extensions needs.
                        At work i had a laptop with intel 4000 HD gfx and even it listed correct openGL version
                        QML would still not work.
                        Just to be sure. You just use the laptops screen, no external screen via USB or anything like that?

                          Yes, I can just use the laptop screen, so it works. But usually I additionally connect another monitor.

                            Maybe you need to configure QT?
                            Or instal emulator newer OpenGL?

                              Hi
                              Well i had issue with a DisplayLink device as it would prevent
                              anything accelerated so thats why im asking.

                              In any case, i wish you would try to run something game-like and
                              if that can run , open bug report.

                                STALKER 3 started up and worked fine.

                                  Hi
                                  The openGL version ?
                                  it can use both DirectX and openGL.
                                  Anyway, if you feel 100% sure you have tested that
                                  openGL does work
                                  as expected on your pc.

                                  You should go to https://bugreports.qt.io
                                  and open bug report.
                                  For QML and Radeon Xpress 1150.

                                  The answer might be its simply too old. but its worth a shot.

                                    Qt has to stay free or it will die.
