You could buy monitors meant to be used as external monitors for laptops. I think most are 15.6" but there's some available at 17". I know that's nowhere near the 24" you use but you could probably carry an additional one. Plus those can be USB powered so you don't have the big hacked together dangerous AC power cable. They'd be lighter weight and thinner than a desktop monitor too. So you wouldn't have some Frankenstein thing that's missing the back of the monitor just to shave off some weight.
