Actual size of the screen is ~9cm x 12cm, if that helps when working out what size to view the image on your monitor.
I'd say that
for me, that's readable in portrait mode in a decent light, but it's near the limit & I wonder if I'd read much at that font-size. On the other hand, the price-step up to the next size displays is rather a big one, so can't really recommend either way!
