    Is anyone else having problems with their MorphOS2.1 display contrast?

    I have tried adjusting my LCD, using different fonts, adjusting settings in Ambient and Ambient MUI, but still no luck.

    It is worse now than when I first started to use MorphOS2.1 on my EFIKA.

    Any suggestions welcome.

    Are you using a DVI or VGA cable? If it's a VGA cable, try replacing it. You may also want to change the display frequency. Even though the autoconfig should give you the best settings for the monitor, trying different refresh rates (60-75Hz) might help with the picture...

    .. or perhaps you're not using the TFT's native resolution? :)

    Thanks for the reply,

    I am usinga DVI to VGA adapter and my Dell 20" widescreen LCD display. The native resolution is 1680 x 800, or something close to that. I think I had tried that once and the icons and text were too small for me to read, even with my glasses. I then tried to use a couple of other resolutions for the Ambient/Workbench screen and had some trouble. Some of them did not display anything at all, just a gray screen. I then used the 1024 x 768 resolution and settled on that.

    I will just have to keep trying different things until I get it right. I was hoping to learn that someone else had already had a similar problem and found a way to fix it and give me his/her tips.

    I could add the native VGA output to my Radeon 9250 card and punch a hole in my EFIKA case for it, if using it would produce better results than using the DVI to VGA adapter.

    Edit: I did notice the same problem on a different monitor, a CRT, so I don't think it is because of the display not being that of the native 16xx X 8xx LCD resolution.

    At least I get a slightly sharper picture by using the VGA-output on the Radeon directly, rather than using a DVI-VGA adapter. So I'd recommend you at least try out the vga-output on the card.
