◆ UpdateCurrentMode()

void MythDisplayX11::UpdateCurrentMode ( )

Retrieve details for the current video mode.

The Qt default implementation tends to get the details correct but only uses an integer refresh rate for some backends.

The MythXDisplay methods now use the modeline to get accurate refresh, resolution and display size details regardless of the number of displays connected - but the closed source NVidia drivers do their own thing and return fictitious modelines for mutiple connected displays.

So we now use the Qt defaults and override where possible with XRANDR versions. If XRANDR is not available we try and get a more accurate refresh rate only.
