If you mean your display performs frame rate conversion (it is possible it has different tolerances for higher resolution formats), then there’s not much to do.

If it is rather due to some unstable sync at higher line modes, you can either try turning off TVP HPLL 2x, or try adjusting sync settings (e.g. increase coast values, or increase Hsync tolerance).
