That’s because your images are actually TOO HIGH of a resolution. Thin lines cause what you are describing because of the interlacing on the TV. The major things to try first are:
1) Render at BEST quality (should use “Best” when using photos but for video only, “Good” is usually sufficient)
2) Turn on “Reduce Interlace Flicker”
3) Maybe add a slight Blur
