Hello There,
I am not sure if there is already an existing fix for this issue in the forum but here it is for your easy perusal.
I just want to share this tricks to you I learned a year ago from a fellow player in other server in regards to the problem I faced with small game screen. If there is an already an existing thread for it, kindly inform me on this thread and redirect us there. Meanwhile, here it is:
1. If you really want a bigger gaming screen, get a 24" or a 32" (inches) monitor. This setup will, most of the time satisfy your visual gaming needs. I have not tried the maximum resolution in the game for (1280 x 900) yet as I don't have those bigger screens. If BP will give me one, would be very happy with it.
2. If you have a smaller screen like mine (15 inches), I setup the resolution to (1280 x 720) and it is the perfect and the maximum screen for me.
Now, to fix the bug of setting up this option:
1. Under "Settings >> Display" option, click on your desired resolution (mine is 1280 x 720.
2. Click "Save" and then click again on "Ok" without waiting for the counter to finish at 0 (zero) seconds.
3. Place your cursor on the "address bar" and click on the URL on it until it has been highlighted or until you can see the background for the text has turned into "blue".
4. Now, press "F5" and it will refresh the whole page and in a matter of seconds you will have the "Full screen"!!!
5. You can also press "F11" to have the "full screen" without access to your "desktop".
6. If the following steps do not work for you, try hitting the "Home" page on the other screen (not the game screen) and hit the "Start" button and do the steps again from 1 to 4 until you achieve the "Full screen".
I do not know the exact reasons why sometimes it fails to achieve a full screen but doing the extra 6th step and going back again to step 1 always fix it on a 2 to 5 times trying.
So a good lesson for all of these, "Try and try until you have a full screen."
I just hope I helped so many people out there regarding this problem...
