Do you have all of your monitors connected to one of your graphics cards? I believe this is expected behavior if you have each of your monitors connected to different graphics adapters, under Windows.

Yes that makes sense but NVIDIA control panel shows both monitors are connected. Also, it did work with a previous version of Blender.

OpenGL is a bit weird on Windows. The primary display creates a proper hardware-accelerated context while the secondary can only make a crappy software one, even though you have a nice adapter. Blender only complains at the point you make a window on the secondary one so everything can seem okay as long as all windows are created on the primary one. But best to just hook up all monitors to one adapter.

It isn’t like this for DirectX (and probably not on other platforms) so this is mostly just a Microsoft thing.

@Harley that seems to have fixed it (putting both monitors on one card). Thanks! It still seems to be an issue though since this did work with 2.92.0. I imagine there are many setups where users have multi-monitor and multi-card setups.

Hi @patricio.davila.ca , can I close the ticket in case error is not appearing at present?
