Nano Texture Coating
Previously the exclusive domain of Apple’s $5,000 Pro Display XDR, the new 27-inch iMac gains the nano-texture glass finish that significantly reduces the glare on that big iMac screen, even in bright lighting conditions.
Most of the reviews so far note that it works really well, standing up to just about anything expect direct sunlight. Unfortunately, it doesn’t come cheap — it will add $500 to the price of your iMac, so you either need to have deep pockets or a real aversion for glare (or both) to justify it.
It’s also pretty fragile, with Apple offering some very specific instructions for cleaning it, but despite these caveats, we can’t argue that it’s a great option to have available on a desktop iMac, where it’s often virtually impossible to keep the glare away even at the best of times.
