Yeah but we’re talking diminishing returns here. Doubling the resolution to 8k makes about as much sense as doubling refresh rates to 480hz. At that point it’s going to be mostly dependent on the individual, and likely heavily subject to the placebo effect.
By my math, a 55" 8k screen has pixels that are 0.056" (56 thou) wide.
At ten feet, that subtends an angle of 0.268 degrees or 1.6 arcminutes.
There’s obviously a lot of variation and it depends on exactly what you’re measuring, but normal human visual acuity struggles to distinguish details less than about 5 arcminutes, maybe 1-2 arcminutes depending on the test.
They have been saying that since 30hz and they still say that with 240hz
