Given a fixed bandwidth and high refresh rate, interlaced video can also provide a higher spatial resolution than progressive scan.

Should I use interlaced refresh rate?

However, with animated graphics -- especially images that move or change form rapidly -- interlacing can produce a fluttering effect at least as irritating as screen flicker. For serious animated-graphics work and video editing, a non-interlaced display is recommended.

What is better 60hz or 60hz interlaced?

Respectable. 60 Hz hands-down. 30i just means that the screen runs at a lower refresh rate but uses refreshing methods that tend to reduce screen tear. However, most media does not support interlaced image processing and 30 Hz is just terrible to look at.
