| − | This deformation can be easily fixed by changing the field V_Sync_Pulse in the system timings. Timing are spread in several files, and they can be found in /home/pi/RGB-Pi/data/timings. The file names are self-explanatory. Once you open any of them, you'll find something like this: | + | This deformation can be produced because some TV models do not accept intermediate frequencies between 50 and 60Hz well, it can be solved by applying a rounding to these frequencies available in the advanced menu of the system. |

| − | By modifying the vsync, you can reduce one unit each try, save the file and test some game until you get the proper value. Once you have it, you can perform a bulk update in the timing file by using any text editor with the replace functionality and searching for " 5 " so that it won't overwrite other values.

To fix this, we must edit the ui-timings.txt and change the corresponding line (FIX/NOFIX), and modify in this case the value 9 following the same procedure explained above.

Some monitors and TVs produce some kinds of image deformations. Next, we will see the most common scenarios and how to fix them:
In-Game top screen deformation
This deformation can be produced because some TV models do not accept intermediate frequencies between 50 and 60Hz well, it can be solved by applying a rounding to these frequencies available in the advanced menu of the system.
