Windows 2016 very low resolution

We've just installed a brand new server (windows 2016) at a customer site.
This server will serve as replacement of an old windows sbs server (AD + Fileserver).
We have not connected any screen to this server and when we connect to remotely to the console of the server, we are limited to a resolution of 640 x 480

When we connect RDP, we have normal, high resolution

We've tried updating graphic drivers, but that did not work.
installing a generic monitor solved my issue, until reboot. then i fell back on default 640x480 resolution.

Does anyone know how to get windows resolution issue solved?

See if the manufacturer has an updated Video driver for that server. You should upgrade the driver and then restart the server.

To expand on that, the reason you aren't getting a better resolution from the console is that windows doesn't know how to talk to your graphics card, so it goes to default resolution. You might be able to go into the display settings and change it. Otherwise, do like John suggested.

The reason is works properly in remote desktop is because that doesn't use the graphics card, rather it uses whatever settings are in your remote desktop client.
