I can see that the Mini is powering up, and that the monitor is on, but nothing. Well, after getting home from Portland and connecting my brand new 2018 Mac Mini, nothing gets displayed on the monitor! I tried all 4 USB-C ports on the Mini, and still no dice. Prior to purchasing my 2018 Mac Mini (i5, 256 gig SSD, 8 gig of RAM) today, I made sure about the adapter I would need for my Sony 19' Monitor: a USB-C to VGA Adapter, and specifically made by Belkin. If anyone knows settings that will let it go through the VGA adapter at 1600x1200, please let me know.Please excuse another thread about displays, adapters/connectors, and the 2018 Mac Mini, but I could use some help. Either way, I am enjoying the nice resolution now, and look forward to using it on my new Mac next summer. Like I said, this was the combination that let it go its highest (1152x870).

I looked through the manual and it seems to differ from the product. The setting I am using is '1' on the dial, and for the jumpers, 1 on, 2 off, 3 on, 4 off, 5&6 on, 7 off, and 8 on. (I have two 19' Micron screens) Unfortunately I cannot afford a Radeon card at this time and all. This monitor is going to go out soon, so I will not be able to use it with BNC connectors much longer. Anyways, what I am wondering is how I am setting the Belkin switch wrong. To my amazement, it can go up to 1920x1080. Tonight I realized 'Why don't I try it through BNC? Then maybe I can select more than one resolution without having to reset the switches on the Belkin!' So I did. Anyways, I have been using it with a Viewsonic PS790 which has both VGA and BNC terminals. I bet this has been covered before, but I have a Beige G3/300 (Oc'ed to 333) with the extra 4 mb ram upgrade for the video.
