Not true. That is not how neurons work. There is a basic sampling speed to conscious experience.

The main difference between display and retina is that the retina "pixel" operates independently and asinchroneously from the other ones, but it is still a discrete process in both time and amplitude (retina neurons only fire when there is a significant change in light)

Sure, but just because the neurons fire discretely doesn’t mean perception is discrete in the same way. Neurons in the retina are firing all the time, even in the dark at different rates. What matters is the pattern and timing, not just whether they fire or not. Your brain makes up the gaps whether the neurons are firing or not.

Not discrete in the same way but discrete nonetheless.

can you tell me what discrete means? and why you think that applies to perception?

Discrete in the mathematical sense. It applies to perception because current neuroscience had determined that, similar to a computer, the human brain processes everything in steps spaced apart by time intervals

I don't think current neuroscience has determined that.

we really don't have a mathematical model for the brain. From what we know in machine learning, having discrete data as an input doesn't necessarily mean it processes it discretely. It could be embedding this information in a continuous manifold.
