Thanks. Indeed 1600×1200 also works with H.synclen 25, H.backporch 32.
If you want 1600×1080 then use V.active 216, V.backporch 29.
I have not been able to get a sharp image with H.samplerate 386. Its only sharp on the left side of the screen with that setting. I use 387 and its almost perfect.
Lets show a comparison picture between lineX5 optimized and generic 🙂
