VGA not working?

[FEkic]

I am trying to give 800x600@56hz vga output with my stm32f103c8t6. For some reason I can't get it to work. Both of the monitors I tried are saying "Input is not supported" or sth along thoose lines.I know that they can work with 800x600@56hz. I have tried other resolutions and I couldn't get any of them to work. In some of my tries I got 800x600 54hz,68hz and 72hz.This happened when I tried to speed up the 640x480@60hz numbers but I couldn't get the desired resolution and the other random ones I got were inconsistent. Here is my code:

I can confirm that the MCU is running at 72mhz. The PA0 is connected to HSYNC and PB0 is connected to VSYNC. PA1to6 are connected to an DAC that I made with resistors but for now they are irrelevant. I would really appreciate anyone that can help cause I have no idea why this is not working

Do you have an oscilloscope?

Unfortunantly I dont ;(
