Windows 10 desktop will not scale to fit correctly on TV

[HaywardPool]

We just had to replace a Windows 7 PC thats in our Factory connected to a Samsung 40' TV

We upgraded it to Windows 10 64Bit 1903 and I am having a huge problem with the resolution. I've been on this for over 3 hours and I give up its at 1920x1080. The problem I am having is that the task bar and all of the desktop go off the edges of the screen and I can only see half of each.

I said ok i'll just DL the Windows 10 drivers for this model and it should be that simple. I go here and DL the latest version. SP99918.exe but it tells me The operating system version is not supported.

Also DL'd the latest Intel Graphics 530 driver from Intel's site below and it installed I rebooted but no change. i thought after installed it would show the Intel icon in the system tray.

Thanks

I think this was my fault. I DL''d the DCH driver by mistake and not the Intel Graphics driver:

Windows 10, 64-bit*
Windows 8.1, 64-bit*
Windows 7, 32-bit*
Windows 7, 64-bit*

I'm going try the install at 3 PM
