I have solved the issue. Its funny and sad cus I spent a lot of time trying to sort this. I dont game on my PC which was the main problem. The first game I tried for my nephew needed a lower screen res. The second game was an older one made for windows XP era so that didnt work and I still carnt. But the third game worked fine because it cud run with a high screen res.
I was using a HDMI cable so res wouldn't go below 1200x900 roughly. When the third game worked I went back to the first game, I needed the VGA cable instead so the res could be lowered to 1080x720 roughly, the game works fine.
Thanks a lot for trying.
