when i am using the s-video input, i could adjust the focus and the vertical and horizontal lines (i dont know what you call it). the resolution is just fine except that the screen is cut at the sides. so, i tried to use the RGB input so i could resize it but the picture is so distorted. i couldnt align the red, blue and green lines to each other. it says "overflow". can you please help me with this? i would really appreciate any help you could extend me regarding this. thank you so much.
