I was trying to connect my relatively new laptop (with Win10, an integrated Intel UHD GPU and a GeForce MX250) to an older Acer X115 projector using an HDMI-to-VGA adapter, but it did not work for some reason. The adapter didn't work with my friend's older Win10 laptop either. To troubleshoot, I used the same adapter, cable and laptop and connected it to a Philips 246E monitor, which worked flawlessly. I also tried connecting my Pi4 (with the most recent Pi OS) to the projector with the same adapter and cable, and that worked too. So it seems that the problem is with the specific combination of Windows 10 and the projector itself. Any ideas what could be the problem?
