When you say everything else fails, are you including getvcp etc? The detect command internally performs getvcp operations to test DDC communication and read the VCP version. The interrogate output also shows successful operations.
capabilities is the most complicated operation. It performs several getvcp operations, each based on what is returned in the prior operation. So if you have a marginal video card/monitor, it's the most likely to fail.
Option --ddcdata (previously named --ddc) reports DDC data errors. I suspect you'll see lot of them for commands that fail.
It appears that you are using a high sleep multiplier for the monitor (2.0) so there's nothing more to be done there.
Your video card is rather old. It likely needs the special Nvidia settings .

Sorry, you are right. getvcp
works. I only tested setvcp.
~ ❯ ddcutil -d 2 getvcp 10
VCP code 0x10 (Brightness ): current value = 70, max value = 100

Yes, I do:

Verification failed for feature 10
It appears that you are using a high sleep multiplier for the monitor (2.0) so there's nothing more to be done there.
I did not (consciously) set it this high. Is it because of my old monitor?
from ddcutil.
I may have misinterpreted your cached sleep multiplier data. Try explicitly setting a high sleep multiplier using option sleep-multiplier 2.0
from ddcutil.
This did not seem to help.
$ ddcutil --sleep-multiplier 2.0 -d 2 setvcp 10 50 --ddcdata

I'm afraid there's nothing more I can suggest.
