    Hey folks,

    I just got my OSSC and am posting for the first time here. I have a Gateway 24″ monitor (LP2407) with a DVI input. I am connecting it to the OSSC with an HDMI to DVI cable. This monitor and cable work fine with the NES Classic and a Raspberry Pi, but I get bad video from the OSSC. See the linked video below for what I am getting:

    The OSSC *does* seem to work fine with my TV through its HDMI input. So I do know the OSSC works (at least somewhat) and the monitor works, which means this is some kind of incompatibility between the OSSC and this monitor, or some incorrect setting. Thanks for any help!

    Does the test card display on the monitor?

    Have you tried other sources with the OSSC on that monitor?

    Have you tried DVI mode on the OSSC?

    The test pattern does not appear on the monitor.

    The monitor does work with HDMI output from an NES Classic and Raspberry Pi, using the same DVI/HDMI cable.

    I didn’t know there was a special DVI mode. Looking at the wiki, do you mean the “TX output” option? If so, is that only accessible with the menu (orange) buttons on the remote, or is there a shortcut? I’ll try it later tonight.

    Thanks!

    Very strange that you would not even get the test pattern.

    Correct, output opt->TX mode. You will need a remote to access this.

    That works! The test pattern now comes up on that monitor, and it also works with an Amiga 500. Is it expected that I need to enable that option for DVI connections? (other devices work without any special configuration) I guess I will have to add that to a profile so that I don’t have to set it every time.

    It’s not always necessary. Some DVI monitors will happily accept HDMI signals, some will even process the audio too, then again, some won’t.
