24 alternatives to SideDisplay
I bought a Tesla Model X in 2023 and kept staring at the 17-inch display sitting idle while I worked on my 14-inch MacBook. I often drive to a quiet spot and work from the car, so I wanted to use that screen as a second monitor. Nothing existed to do this, so I tried building it myself. It took over a year of failed attempts: - Hardware mod: didn't want to void the warranty - Zoom screen share: worked but terrible latency, no fullscreen - HLS streaming via OBS: ~2 second delay, unusable as a monitor - WebRTC: Tesla's browser didn't support it at the time A few Tesla software updates later, I…

Raybeam▲209Problem A few years ago I got my first ultra-wide monitor. It was a 49" Samsung monitor. I work as a software engineer, and in my line of work I need to screen share a lot. This almost immediately became a problem due to the size of the monitor. I would either need to get a second display just for screen sharing, share one window at a time (which required me to constantly stop/start sharing to select the new window), or share my entire screen making it difficult for other participants in the call to see what I'm doing due to the size of my display. I wanted a solution to this. At the…

Two browser windows (acting as socket clients) communicate their: - Screen dimensions - (screen.width, screen.height) - Window dimensions - (window.innerWidth, window.innerHeight) - Window X/Y position - (window.screenX, window.screenY) ...or whichever calculation works best for you. The original work by Bjorn Staal https://twitter.com/_nonfigurativ_/status/172732259457002734 used localStorage, but I found sockets more fun, because if tweaked a bit, this can be shared with friends. Here's a demo of how it works and the codebase:…

Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here! With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window compositing, scaling, and streaming engine now. CoScreen was always meant to be different so that you and your team can share your screens simultaneously and multi-directionally, and to be able to control what is being shared. We saw it as a natural extension and closely coupled…
