Holograms

Quick question: in the Star Wars universe where folk are smart enough to build spacecraft that can travel faster than the speed of light, where they've created laser guns and lightsabres, where children create cognitive robots and pod-racers in their spare time, why is it that the most powerful organisation in the galaxy can't create a hologram with decent resolution?

Those things look like the holograms that used to be sold in Athena back in the 80s.
