Tldr: you’re better off just buying a new monitor, and don’t go down the road paved with adapters and vague vendor promises. That way lies madness.

I’ve tried several combinations of docks and adapters, and if you do go that way, only get a dock which natively outputs something your monitor accepts and stay the fuck away from Targus, their display link implementation will add a whole new layer of frustration to your troubleshooting.

Adapters often require power, and sometimes the dock can’t supply that power in the long run. I have had setups work for 4months before suddenly a monitor dropping out randomly. As in working fine, then no connection and a few seconds later back online. After 3 docks and 4 sets of adapters, the only thing that worked was dropping the adapters and getting new monitors.
