Both are practically infinite, or well, the question doesn't really make sense.

Reality isn't rasterized, so there's no resolution. You just have light waves bouncing off of things and into your eyes. They can hit at all kinds of angles and positions, and your brain will interpret different impact frequency distributions as some color or brightness you see in a certain position.

And you don't have a shutter in your eyes or something else that would isolate individual frames. Light waves just arrive whenever they do and your brain updates its interpreted image continuously.

So, in principle, you can increase the resolution and display rate of a screen to infinity and you'd still perceive it differently (even if it's not noticeable enough to point it out).
The cost just goes up ever more and the returns diminish, so the question rather has to be, whether it's worth your money (and whether you want to sink that much money into entertainment in the first place).
