We'll have wall-sized 20K TV's in 10 years, but computer monitors will still only be 1080p...because stupid.
Nah, The reason PC monitors have been stuck in the HD-age is because LCD TVs were damn cheap to produce and took practically nothing to repurpose into monitors. Since the death of CRTs, TVs and Monitors have converged into more-or-less the same device, at least as far as manufacturers are concerned. The second that 4K TVs become dirt cheap to produce in 13"-30" sizes, you will see 1080 monitors going the way of the dodo. Same with 8K, etc.
