There are quite a few if you know what to look for. Ex: a 4k in 15 inch format: https://www.amazon.com/15-6-Portable-Monitor-External-Consoles/dp/B098NHT123 https://www.amazon.com/15-6-Portable-Monitor-External-Consol... About 300 dpi, so about 33% better than Apple's retina brand. Plug the numbers in https://www.sven.de/dpi/ https://www.sven.de/dpi/ and you get: > Display size: 12.98" × 8.65" = 112.32in² (32.97cm × 21.98cm = 724.64cm²) at 295.84 PPI, 0.0859mm dot pitch, 87521 PPI² Actually, it's far better than a retina display: OLED is something not available on macbooks I have a few, they're a pleasure to use. And I love the integrated battery to travel with a dual screen setup with just a USB-C cable and my laptop!
