Achieve a 1280x800 resolution despite the need for Full HD.
Hi, I'm facing a tricky situation. I work in a public school in Denmark as the local IT specialist. We use Lenovo T-470 devices and after updating to Windows 10, we're encountering issues with projector resolution in classrooms. Most of them are NEC models running at 1280x800, and many staff want to run the setup in duplicate mode. When I set the resolution to 1280x800 in duplicate mode, the screen scales on both the laptop and the external display, but the output remains 1920x1080. On the NEC units, the Full HD signal appears blurry and the image is smaller, while other projectors flicker. The main IT department dismisses it, saying duplicate mode isn't supported in Windows 10 for resolutions below Full HD. It functioned perfectly in Windows 8.1. I've experimented with adjusting the image settings from IT and tried standalone installations without success. Is this just a limitation of Windows 10? I have an IT background, but my colleagues at other schools are teachers and aren't much help here. The main IT department seems indifferent to schools, so I'm handling it on my own. Regards, Michael
