Kit, 22" main monitor 17" second monitor, Windows 8, Google Chrome.

Here is an interesting one.

On start-up, I have no problem with the monitor.

I have s full 'screen with multiple tabs on the Google chrome window.

I tend to move things between the two monitors depending on what I am focused on.
So when I move the Chrome screen over to the smaller monitor I then click to fill that screen.
When I take the Chrome screen over to the big monitor it will not fill the screen!

at some point, the windows on the 22" fill approx 1/3 of the screen,
I can switch to full screen but I loose the tabs.

I can not find a way to get the normal full screen with tabs.

Does anyone have any ideas?

Regards & Happy New Year. Stewart
