The main problem : Let me explain you the problem guys
The problem is your monitor , basically if your monitor is 1280x1024 the game will never work in my opinion they changed that when they added the new video settings so i recommend you to buy an 1366x768 because your game will work perfectly without any problem but if you don't have money to buy that just look at the fix ! will that was the main problem that i've detected also i saw that the 1/2 of people that have this problem always have the old graphic card message displayed on their screen wich make perfectly sense !
The problem fix :
So the fix is so easy all what you need to do is to open your minecraft launcher ( this fix works only in the new launcher xD ^^ ) then go to edit profile and enable resolutions.When you do that write 400 in the first one and 300 in the second one ( 400x300 ) then save your profile and the game will launch without any problem !But there is one more step that you may do to make the game playable because you can't play the game with 400x300 resolution ^^ that's why in this step you just click on the maximize button and here you enjoy !
