Coming from the Retina screen of my laptop that <a href=\"https:\/\/blog.tomayac.com\/2020\/03\/23\/my-working-from-home-setup-during-covid-19\/\">I worked on for a long time<\/a>, I was initially (and still am) not impressed by the resolution of 2560\u00d71440. It took some time to get used to the low resolution on such a big screen, but it gets the job done\u2026<\/p>\n<p>My biggest gripe with the screen was that it just <strong>randomly turned off<\/strong> when connected to my MacBook Pro in clamshell mode. I finally found the culprit after combing through the <a href=\"https:\/\/support.apple.com\/guide\/console\/welcome\/mac\">Console<\/a> system logs for <em>any<\/em> trace for the longest time. I found out that the MacBook Pro thought the power was changing from grid to battery and <em>vice versa<\/em> (all while being constantly on-power), and whenever it did that, the screen would turn off.<\/p>\n<p>The solution was to disable the &quot;Smart Power&quot; option in the screen's settings. According to the <a href=\"https:\/\/psref.lenovo.com\/syspool\/Sys\/PDF\/datasheet\/ThinkVision%20P27h-20_datasheet_EN.PDF\">manual<\/a>, the &quot;Smart Power&quot; option does the following:<\/p>\n<blockquote>\n<p>Smart Power intelligently distributes power to connected USB and USB Type-C devices, maximizing power supply efficiency while also reducing overall consumption.<\/p>\n<\/blockquote>\n<p>Turns out, it wasn't so smart after all. I saw it range between 65W and 90W, but after turning the option off, the laptop gets a constant 65W, all my USB-C devices still work, and I'm happy to report that the screen no longer randomly turns off. This is the blog post I wish I had found when I was looking for a solution, so I hope it helps someone else.<\/p>\n<p><img src=\"https:\/\/blog.tomayac.com\/images\/lenovo-p27h-20.jpg\" alt=\"Lenovo ThinkVision P27h-20 settings with the Smart Power option circled.\" \/><\/p>\n\n\t\t\t<p>\n\t\t\t\t<img alt=\"Thomas Steiner\" width=\"32\" height=\"32\" src=\"https:\/\/blog.tomayac.com\/feed.php?dl=https%3A%2F%2Fblog.tomayac.com%2F2024%2F02%2Flenovo-p27h-20-randomly-turns-off%2F&dp=%2F2024%2F02%2Flenovo-p27h-20-randomly-turns-off%2F&dt=Lenovo%20ThinkVision%20P27h-20%20screen%20randomly%20turns%20off%20when%20connected%20to%20MacBook%20Pro\" alt=\"\">\n\t\t\t\t<br\/>This post appeared first on <a href=\"https:\/\/blog.tomayac.com\/2024\/02\/lenovo-p27h-20-randomly-turns-off\/\">https:\/\/blog.tomayac.com\/2024\/02\/lenovo-p27h-20-randomly-turns-off\/<\/a>.\n\t\t\t<\/p>\n\t\t","protected":false},"excerpt":{"rendered":"<p>\t\t\tThe Lenovo ThinkVision P27h-20 screen I get from work is a decent 27 inch screen.
