In service menu monitor hides 0-255 overdrive gain for fine tuning, but we only get 3 cherrypicked levels in OSD. Perfect gain for 240 Hz fps sits exactly between Fast and Faster which is quite bad if u plan to use just ~240 Hz fps. Here is a nice chart for demonstration. Everything above optimal green line means noticeable overshoot.

Image
  • OFF = 0/255
  • Normal = 6/255 (optimal at ~55 Hz fps)
  • Fast = 25/255 (optimal at ~135 Hz fps)
  • Faster = 90/255 (optimal at >240 Hz, ei. ~350 Hz)
I can confirm values above are correct.

"Optimal" is what ideal variable overdrive would do, but unfortunately such features are not available on most monitors. For manufacturers reading, if you're not ready for variable overdrive yet, at least give us a 100-level slider. It's a free and easy to implement feature which everyone can appreciate. Please let the user pick their overdrive just like brightness and every other setting in OSD.
