The effect of different resoltions on the eyes?

mttylad

Hello, does anyone know of any sources of the effects of mixed resolutions on he eyes?

I am referring to having a multi monitor setup and having different resolutions on each one and how it causes eye strain/headaches etc.

Cheers,

I don't know, but I can't see (!) why there should be any inherent problems.

I think the biggest issues relating to eye strain would be to do with brightness and contrast and perhaps the refresh rate (although that only applies to CRT screens).

I switch down the brightness and contrast when first setting up a computer and leave it that way for years. I also with in a room that is well lit.

With regards to the resolution; Logic tells us that the bigger the writing/image detail (pixels) the less the eye will strain to see them. And that tiny, high resolution, detail/writing should logically cause more eye strain/squinting. To remedy this I use size 14 font in word for example.

Oh, I'd have thought (if anything) the lower resolutions would strain the eye more as your brain has a more jagged image to mentally smooth out.

A high resolution would be smoother and so easier on the eyes. But that's assuming that you're using the same size text (as measured on the physical screen).

Anyway, I'm doubtful that it does make a difference...

There's a 12-year-old research paper "Effects of Screen Size, Screen Resolution, and Display Rate on Computer-Based Test Performance" (PDF) on this topic which the OP might like to read?

Its the constant change from one resolution to another while you go from one monitor to another that I am referring to.

This can happen when using a laptop and an old monitor.

Cheers John, I'll read that pdf.
