Sorry Android fans, Apple is right: 1080p is all we need for smartphone screens

Your eyes deceive you.

- BY MICHAEL SIMON

Ihave seen the light. Or more specifical­ly, I have seen the brightness, contrast, and pixel density. After weeks of testing, I’m ready to declare the iphone 12’s Full HD (1920x1080, or 1080p) screen just as good as the Note 20 Ultra’s WQHD (2560x1440) one, if not better. Android phone makers have convinced us that we need 2K or higher screens to get the best viewing experience, but that’s just not the case.

I don’t want to make this about Apple vs. Android, but the fact of the matter is, we never needed displays with WQHD+ resolution. We simply wanted them—or rather, phone makers convinced us that we

wanted them. Full HD displays have become relegated to budget Android phones as more emphasis is placed on immersive, edge-to-edge, pixel-packed experience­s. You need look no further than Displaymat­e’s iphone 12 Pro Max OLED Display Shoot-out ( go.pcworld.com/dpmt) to see how wrong that thinking is: The iphone 12’s Full HD display received the highest-ever A+ display performanc­e grade.

But all those extra pixels just aren’t necessary. Case in point: Samsung ships with its Quadhd+ resolution turned off by default. I’m willing to bet many people who buy one don’t even know how to turn it on. Super-high-resolution displays are nice on spec sheets and in macro testing, but on a six-inch display, the results are basically indiscerni­ble to the human eye. If the jawdroppin­g Infinity display on the Galaxy S8 had maxed out at 1080p, no one would have complained.

Android enthusiast­s may claim they can tell the difference, but I doubt they would be able to pick a 1440p display out of a 1080p lineup. I should know; I was one of them. There was a time when the first thing I did when I got a new Samsung Galaxy phone in for testing was bump the resolution from 1080p to 1440p. I would have challenged anyone that my eyes could tell the difference.

They can’t. When Samsung launched its first phone with a 120Hz refresh rate earlier this year, I was among the reviewers who criticized it for not working with the higher-resolution setting. I was so convinced that WQHD+ was the superior setting that I questioned whether the 120Hz refresh rate was worth downgradin­g to a lower resolution.

It is, and Samsung is smart to limit 120Hz to 1080p. Even without a fast refresh rate, 1080p screens provide 400 to 450 pixels per inch, well above what Apple’s Steve Jobs called the “magic number right around 300 pixels per inch, that when you hold something around…10 to 12 inches away from your eyes, is the limit of the human retina to differenti­ate the pixels.”

TOO MANY PIXELS

For a while there, it looked like phone companies were going to start competing in the 4K space, starting with the Sony Xperia 1, which had a whopping 3840x1644 resolution and 643ppi pixel density. While Sony has continued to trot out ridiculous­ly high-res screens—with a rumored 5K, 900ppi model in the works—overly high-res screens haven’t really caught on.

That’s a good thing. While 2K, 3K, and 4K are great for spec sheets and marketing copy, the extra pixels are, for the most part, unnecessar­y and even detrimenta­l to the overall experience. High-resolution displays use more battery, tax GPUS, and occasional­ly, disrupt app layout and performanc­e. They deliver few benefits beyond the perception that images and fonts look crisper. In short, 4K is great on a TV, but wholly unnecessar­y on a phone.

The same goes for 2K and 3K. On paper, Apple’s iphone 12 displays are pedestrian compared to those on most premium Android phones. But specs don’t tell the story. Apple takes such care with the calibratio­n of its displays to make them visually indistingu­ishable from the excellent WQHD displays on Galaxy phones and light years better than Google’s 1440p Pixel phones. Now that Apple has finally gone full-oled with its iphone lineup, there’s very little left to criticize, apart from the lack of a 120Hz option. Rumors suggest that will come next year, which will put the iphone on a par with Samsung’s best, even with significan­tly lower resolution.

Apple cares more about display quality than pixel quantity, and it’s willing to yield a bit to its competitor­s to get there. In doing so it’s proved that we don’t actually need resolution better than 1080p. I’m hoping other phone makers will stop trying so hard and follow Apple’s example instead.
