How to fix the huge display on the monitor?
As long using Microsoft Windows OS, try these instruction above.
Now, look at background image on the desktop, where icons laying on there. Right-click on the blank on the background image, then click "Properties", a new window will appear. You now just need to switch the tab to "Settings", and get the "Screen Resolution" to higher by move it to the right side.
It also working when the colours on display seem so bad, just look at the "Color Quality", turn it to the higher bit (usually 32 bit or 64 bit if there is).
