Question about playfield display refresh rate

Recommended Posts

I'm looking a getting a 27" led for my mini build I'm about to start, for the playfield.

A friend thought I may research the refresh rate and ask if I should be pursuing 120 hz or if 60hz is ok?

More importantly you want a tv with game mode. That reduces the refresh rate to 60hz and puts focus on fast response time. So more then 60hz is overkill. But what what ever you get, make sure it has a game mode.

Is there noticeable difference between 2ms and 5 ms response time?

"Response time" in that case is probably referring to how fast the pixels can change state, which is mostly meaningless with modern equipment. That was an important statistic in the early days of laptop LCDs, but any display made after about 2000 is so fast that you won't see any difference. The main thing that pixel response time affects is motion smearing; most modern LCDs are very good at rendering motion.

The statistic that really matters for virtual pinball (gaming in general) is input lag, which I've never any TV manufacturer quote in their official stats. If you're seeing a number like 2ms or 5ms, it's almost the pixel switching time and not the input lag time. Input lag times for TVs tend to be much higher, and are all over the map, from about 30ms to 250ms. There's an article here with some lab tests for various models, but unfortunately it's more than a year old, so it obviously won't have data for the latest models: http://www.cnet.com/news/game-mode-on-cnet-tests-tvs-for-input-lag/

If possible, use a TV with a "game mode" setting. Most TVs have a variety of proprietary image processing features that contribute to input lag; game mode usually turns those off to get the fastest possible signal-to-display path for the model.
