My comment was based on visual acuity limits. A person with 20/20 vision and a 32" 4K display will hit that limit at around 2ft. Going to a higher resolution you won't be able to see individual pixels anymore unless you have better than average eyesight or sit close to your monitor.

The GPU bit was purely about games and how many pixels you are pushing in games vs cost for a minimum quality and performance level. For content consumption or creation use it isn't a problem.
