The Best Monitor for Programming: A Cheap 40" 4K TV
If you enjoy a low density of 110 pixels per inch, then this is for you.<p>I&#x27;m much happier with the high-DPI displays in my ThinkPad Yoga 460 WQHD and MacBook Pro Retina 15&quot;.<p>I don&#x27;t <i>like</i> pixels, and I don&#x27;t want to see them any more. I want to see the text and graphics I&#x27;m working on, not pixels.<p>So when I wanted a second monitor to go with those machines, I got a 24&quot; 4K display. At 187 pixels per inch, it&#x27;s a reasonably close match to the 210-220 pixels per inch on the laptops.<p>I use this monitor in portrait mode next to the laptop display. A portrait mode monitor combined with the laptop monitor is great. I&#x27;ve got a wide screen when I want it, and a tall screen when I want that. It&#x27;s ideal for reading documentation and especially PDF files, because an entire page fits on the portrait screen. Larger monitors are not very practical in portrait mode.<p>I&#x27;m not concerned with cramming the maximum amount of stuff on my screen. I run the monitors at 225% scaling in Windows, and the default Retina scaling in macOS. So text is about the same size it would be on a lower-DPI monitor, just much sharper and crisper.<p>After I got my first taste of high DPI with that MacBook, I swore I&#x27;d never go back to a low DPI display. It is so nice to not have to look at <i>pixels</i> any more.
