Screen resolution of A7IV

I've seen a couple reviews so far that complain that the screen resolution is not improved enough.

I know that the human eye cannot generally detect changes above ~280 dots per inch unaided. The screen resolution of the A7IV is 288 DPI. Anything above that would be needlessly pumping extra pixels and therefore wasting battery power.

What do you think?

This number depends on viewing distance. Since it's such a small screen people probably look at it closer than their phones, and modern phones often run 400dpi+

This also depends on the content being displayed, I have serious suspicions on the actual render resolution of Sony's menu system, if the text isn't rendered at native resolution properly, it won't look crisp regardless of screen resolution.

Same goes with images, if the LV feed isn't the correct resolution it won't look very high resolution.

That number is based on the minimum distance that eyes with good vision can focus. Any higher resolution would require a form of magnification aid in order to see a difference.

I personally don't have any issue with any of the screens (or the way things are rendered) on any of the Sony cameras that I own, other than maybe color balance.

[edit] Actually, I do take issue with the color of the focus point on the A7III, but that's outside the scope of display resolution.

No it's not, not even close. I can easily put my eyes up close to a 500dpi display and see the pixels.

Are you near sighted?

As an anecdote, my right eye was cataract and before I completely lost my vision in that eye, I was able to see my phone (and the individual pixels) three inches from my eye.

Anyway, my information could certainly be wrong.

The colour accuracy seemed to have improved over the A7C, where the image from the camera screen pretty much resembles the image from my iPhone/Macbook screen.

What screen resolution is judged as acceptable depends on how you use the camera screen. For framing and checking focus, even with magnified/loupe view, lower resolution screens work just fine. Or do you expect a smooth view when zooming in the images and placing your eyes as close to the screen as possible?

From my point of view very high resolution screens is not needed, since raw files are brought into a computer for post processing anyway, and you need to check jpg files on your computer too, to ensure that the in-camera jpg settings are optimized for your workflow. Many prefer high resolution camera screens, though. Personally I find a high resolution electronic viewfinder much more useful.
