Hope I'm posting in the right place. I'm wondering if anyone has any ideas on this.. I'm trying to connect my phone to my projector. It is an older projector and does not have HDMI. It does, however, have DVI and I've been using an HDMI-DVI cable to connect it to my laptop and xbox. When I tried to connect my MHL adapter to this HDMI connection, there was a response on both devices but the picture from the projector remained black. I suspect it's an issue with the resolution. Is there a way to adjust the output resolution on the phone? I haven't found one yet.
