    Thank you very much!!
    Shift+LMB did not work. I guess because the wrong/correct screen resolution is loaded *before*.

    But: With some luck, CTRL key work.

    And I guess I have found the reason why I am having trouble: It is due to my monitor.
    Booting with CTRL key I got some standard screen, as you described. If I then set the sreent resolution to 1920x1080 - my Philips Brilliance 241B has 16:9 format - I immediately get the info: Wrong screen resolution. Set it to 1920x1080@60Hz. And the screen get black.

    Okay, I again did the procedure and had a closer look:

    For the X1650Pro I only can choose a 1920x1080@76Hz. Obviously my monitor cannot display that.
    Now I have changed to 1280x720@60Hz: And this does work - but of course is not that fun.

    Funny enough: If I am remembering correctly, for my HD5450 there also is only 1920x1080@76Hz available but the monitor can display it. Has anybody an explanation for that???
    Could this has anything to do with HDMI connection (HD5450) and DVI connection (all X-cards)??

    And is there any poosibility to add a screen resolution of 1920x1080@60Hz for the X-cards?

    Thank you!!!

    You could try this workaround. (Shot in the dark, though.)

    Thank you.

    But in this case - for once i found this out myself - it is much more simple:
    MorphOS does recognize my monitor: Philips Brilliance 241B. But obviously assigns a wrong freqeuncy of 75Hz.

    ---> System: Prefs/Preferences/Monitors

    Under monitor specifications my monitor is listed.
    Choosing '24Bit 1920 x 1080' under Screen resolutions and then 'Edit....'.
    And there a screen resolution of 1920 x 1080p (60hz) is available.
    Test....Working!
    Ok....Save....Restart.
    And yes, it works! :)

    I have only one question:
    What is the difference between '1920x1080p(60hz)', '1920x1080 (60hz)' and '1920x1080(60hz)CVRB2'?

    It was Shift or LMB, but not simultaneously.

    I guess there are different settings (pixel clock, sync and pulse values, etc) for same resolutions that are standards or common enough otherwise. For example, that last one seems to refer to this: https://en.wikipedia.org/wiki/Coordinated_Video_Timings.

    I guess you should just try which one works with your monitor if you don't know better :)

    EDIT: well...... I changed from 1920x1080p to 1920x1080 CVTRB2 myself.... less bandwidth, less load to gfx chip or something? :P

    For future references, it seemed to modify a monitor file in Prefs/Presets/Monitors/ directory. And you can see name of the monitor file from the Prefs/Env-Archive/CyberGraphX/RadeonMonitor file. If someone needs to play/fix/revert/debug these settings...
