That’s executive functioning failure. It’s common with ADHD (which is strongly comorbid with Autism) but not unique to it.
Basically, the part of your brain dealing with task focus is either asleep or exhausted. At that point, you are running on pure impulsiveness.
If you get locked in, the best bet is to stop banging your head against a brick wall. Stop trying to do the big task, that is stressing you. Instead aim for a small, neutral or positive task to lock on to. E.g. throwing together a sandwich, or going to the loo, rather than “I REALLY need to get my taxes done!” It’s a far from perfect method (it still fails often), but it does help kickstart you back to higher brain thinking.


Uncompressed 1080 is already approaching the eyes resolution limit, when viewing it in a living room environment. 4K is close to the monitor usage limit.
The reason that 4K seems better is often down to bandwidth and colour depth.
There’s zero benefit to an 8K TV. An 8K monitor might be useful, but is still well into the diminishing returns curve.
There’s still some ground to be made up with colours and frame rates, but resolution is effectively maxed out already.
