    Hi.

    I've updated two days ago.
    In MorphOS 3.12 I had a screen resolution of 1900 x 1080 (or similar).
    After updating the highest screen resolution I can select under "Screens" is 1680 x something.
    However, under "Monitors" I can still see the 1900 x 1080 resolution and can "test" it.

    Not sure what's going on.

    It is impossible to tell since you have not provided any details about the hardware. Graphics card, monitor and ports in use (DVI, etc) would be a minimum.

    Well, it hasn't changed from 3.12 to 3.13.
    Need to check tomorrow on the hardware...

    OK. So hardware:

    It's a PowerMac G5 7.3 2GHz.
    Gfx: Radeon 9600Pro.
    I'm using the left (viewed from the front) DVI port.
    Monitor is a 28" IIYAMA G-Master GB2888UHSU-B1.

    Under "Monitors" I can see the resolution 1920x1080x24.
    But under "Screens" the type is not available to choose from (which was available previously with 3.12).
    The highest resolution is: 1680x1050

    Changing (lowering) the pixel clock for the mode in Monitors should help. We've disabled screen modes that are out-of-spec for a given card output - monitor combination, but unfortunately the auto-generated modes might not always be optimal for some edge cases. This is likely to improve in 3.14. In the meanwhile, manually editing modes will help.

    OK, lowering the pixel clock a bit did the trick.

    Thanks
