HTML5 web viewer on a 34 in curved wide-screen monitor

Is anyone having an issue with viewing a HTML5 web viewer on a 34 inch curved wide-screen monitor?    We're using Chrome and after about 30 minutes a line forms across the middle of the browser and the upper have is blurry and the lower half is fine.  If the browser window is reduced to half screen the problem goes away.   If the browser is restored to full screen, after about 30 minutes the same half blurry half fine behavior occurs again.  We're trying other browsers, but I wondered if anyone else is seeing a similar behavior.  Any thoughts?

 

 

Thanks,
