Windows 10: 4K resolution through a VGA cabel with a 1080p TV?!

    4K resolution through a VGA cabel with a 1080p TV?!

    I connected my PC to my 1080p TV and when I went to the setting I saw that 3840x2160 resolution is available, even at 60 Hz. How is that possible? It's even through a VGA cabel, which supports a maximum res. of 2048x1536. Last time I connected the TV the maximum res. available was 1920x1200, which is also strange because the TV is only 1920x1080. See for yourself:

    That is not what that means.
    Windows is not getting back the info from the TV about specified resolutions that it supports because it's a VGA type connection.
    That is a 'generic' range of resolutions your Graphics Card will support but not necessarily the monitor.

    You would have to use HDMI for that, you would probably also get a model/manufacturers/TV name rather than 'Generic PnP Monitor'.

    Don't think I have seen TVs with DisplayPort but someone will know, mine are a few years old.

    Some years ago, before HDMI, Monitors (VGA) were supplied with a 'driver' which basically was an *.INF and *.ICM file. The *.INF file told Windows what resolutions etc the monitor supported and the *.ICM was a colour profile.
    I don't think such driver files were ever supplied for consumer TVs.
