In Windows 10 where do I find actual resolution video sent by graphic card?
In Display Settings I can see Display resolution drop down. I think, the recommended value in Display resolution is the resolution of the monitor, but the graphic card may be sending video in lower resolution (according to it's max capacity) and monitor upscales it.
How to find the current output resolution at which video card is sending the output to display (In Windows 10)?
Right click on Desktop, go to Display Settings and then search for the Advanced Display Settings option. There you should have Active signal resolution.
