Digital TVs do video processing in order to figure out how to draw the picture on the screen, given that the input resolution and the display resolution are probably different.
Any decent TV will have a video game mode where that video processing is turned off. I have no idea if a Dynex does or not. At least on my Sony, if I remember correctly (since it isn't something that gets changed often), when I set up the inputs and tell the TV what each input is connected to, the input that say "video game" get no video processing done to them.
>My dynex is basically a knockoff of a older LG T.V. It doesn't have a video game mode. Also do you think switching my plug ins to HDMI instead of VGA will speed things up?
Then you are out of luck and there is nothing you can do. Changing to HDMI cable should make absolutely no difference.
