Can anyone help me with a Dell #OptiPlex?

Boot starts Windows setup (which I don't want), but pressing F2 during boot seems to be invoking a video mode that my very old HDMI monitor doesn't support.

It has an HDMI signal but the display shows "NO SUPPORT", unlike if I just let it boot to the Windows installer which displays correctly.

I'm trying to get to the BIOS so I can boot from a USB with #Proxmox installer and then setup #HomeAssistant using the Px script.

@happyborg I don’t have an optiplex available but I recall that you could set it to use the vga or hdmi output in bios, but it won’t auto detect and switch. If you have a vga monitor try that, otherwise you might need to get a vga to hdmi dongle so you can see the bios

@rnDoug thanks but although symptoms made me think this was a different issue, I now believe it's mainly to do with the connector on the monitor/TV.

I've been able to get it working enough to install #Proxmox and have ordered a new cheap monitor for when the existing one fails.

Challenge now is to get internet on the #OptiPlex using only a mobile hotspot - so no way to install WiFi support. I'm hoping I can do this with a wired connection to my laptop.

@happyborg @rnDoug the RF-style connector you mentioned might be for an external WiFi antenna, though if it didn’t have the antenna it also may be missing the WiFi module (usually m.2 connector) on the motherboard.
