Looks like a few successful ideas on page 2 of this thread: http://www.sevenforums.com/gaming/8950-cannot-full-screen-games.html
Hi, I have solution for this. This probably occur for certain laptop
or desktop that running Intel or ATI graphic and have widescreen. Ok
here it is...
For ATI:
1. OK what you need is the CCC(Catalyst Control Center) download it from ATI website, but if you using laptop download it from your
manufacturer website.
After downloading extract and install the files that provided by your manufacturer software... then restart your laptop.
After restarting, change your screen resolution using windows to 1024x768... Do it first... You will notice that is a black border on
your side of the screen.
Next is to open the CCC, right click on your desktop and choose "Catalyst Control Center", better use the basic view, if you done this
before in vista you will remember right what going next, if don't here
it is...
OK, open the quick setting tab > click on notebook display panel > resize the desktop to fit panel > klik GO!... Then choose the middle
option, that says to "fit the panel display"... then... apply then
OK!
Last is to change your resolution back to the recommended 1200x800 or 1366x800 ( depends on your monitor)... then it works, this will
success for certain game such warcraft 3, CS and other game that
always been issue on black border...
Or
The ATI Chipset used in Laptops needs to be modded to work properly.
Go to http://www.driverheaven.com and download the ATI Mobility Modder
(or nVidia if you have this). Follow the 3 easy steps to mod the
Catalyst 8.12 and you should be able to use it properly on any ATI
chipped laptop.
Also, less convincing:
HEY GUYS! I FOUND THE BEST AND THE SIMPLEST SOLUTION! DURING THE
GAME...JUST PRESS Ctrl+ALT+F11... IT WORKS! everyone here says to get
in the nvidia control panel and do some stuff...me...I don't have
nvidia or ati...mine is intel...so all that all of you have written
didn't help me...just do what I've said... Sorry if someone of you
have already post this...if you have I didn't see... ok...I HOPE THIS
HELPS! GOOD LUCK!
Try going into 'Control Panel' through the start menu, and accessing the 'Mouse' option.
Under the 'Pointer Options' tab, uncheck 'Display pointer trails' and press 'Apply'. (this seems to be a common issue)
Under the 'Pointers' tab, uncheck 'Enable pointer shadow'.
If you are running Windows 7, or possibly Vista (not sure about vista), go into the 'Personalization' option within Control Panel, and try switching the theme from 'Aero' to 'Basic'.
From there, you could try installing the latest graphics drivers.

What you're explaining happens to me in CS:GO. You are playing in lower resolution than your native desktop resolution:

Have the same resolution, both in game and on windows settings, or play on a lower resolution and pix-elated game-play but higher frame-rate.
As I said my native monitor resolution (and my windows setting is 1920x1080, my overwatch is at 1600x900, so I get this:
