Updated July 2021.

This is a list of monitors that meet the following criteria:

  • Native 120Hz+ panel and supports 120Hz input at 720p+.
  • 40” diagonal or larger
  • 16:9 aspect ratio
  • flat, not curved

Features that do not affect IIDX or BMS simulators will not be explicitly called out; such as FreeSync, G-Sync, HDR, and so on.

Lightning Model display

For reference, according to this page, Lightning Model cabs use the following primary display:

  • Manufactuer: GTT
  • Model: TLK-4300
  • 43” VA panel at native 1080p 120Hz.
  • Cab boots into Windows at 1080p@120Hz, and then switches to 1600x900@120Hz when the game boots. DisplayPort cable is used.
  • The game is still native 720p; it just gets upscaled. Presumably, the GPU scales the game from 720p to 900p full screen, and then the monitor upscales 900p to fit 1080p panel.

There are also a handful of TVs that are small enough (less than 55”) and support native 120Hz input; e.g.,

  • Sony X85J
  • Sony X90J
  • LG NANO85
  • LG 48CX (OLED)
  • REGZA 43Z730X

… and so on. This is a rapidly growing segment especially in 2021 – you should look for reviews on Make sure the size of TV you are buying actually uses a 120Hz panel - it is common for TV manufacturers to use 120Hz panels for larger sizes but only 60Hz for smaller sizes of the same model – Samsung is the worst offender in this regard.
