Questions about PWM and motion interpolation.
By your test, now I know most of Samsung TVs in recent 2 years will decrease their PWM from acceptable values to exaggerated low 120 Hz while turning on Auto Motion Plus.
The mechanism makes me curious. In your opinion, what’s the reason a TV needs to decrease its backlight flickering frequency when motion interpolation is activated ? Besides, why does they designate to 120Hz, not a higher and acceptable frequency for most people, is it related to their native refresh rate ?
Thanks a lot.

Hey RTINGS team, I saw that you guys were going to update the LG C2 42-inch monitor with the new test bench, but now it’s not on the list anymore. I was really looking forward to the new review! Any chance you can let us know what’s going on with that? Appreciate all the awesome work you do!
Unfortunately, we no longer have the unit we purchased in the lab, so we can’t conduct any additional testing. Sorry about that!

Greeting I can’t decide which of the monitors to take, Dell AW 2723DF or AOC Q27G3XMN or Gigabyte M27Q X, I prefer high-quality IPS panels, but I’m still looking for the best option So I’m looking forward to updating the Gigabyte M27Q X review to version 2.0

I would like some clarification about VRR Flicker. If I understood the wording correctly, it happens on the transition (both drops and increases?) between different frame rate values? If so, how large of a gap it has to be to cause the flicker to occur? Perhaps the frame rate line could be added to the graph for more clarity? I’ve just checked the AW3225QF and it seems really annoying in the dark scene… Its mentioned that it “isn’t a problem if your PC can maintain a consistent frame rate”, but there are games in which the frame rate varies wildly even on top end machines, just by the nature of it. Anyway, thank you for improving the quality of the already awesome reviews!
Hey this is a good question! It’s hard to say exactly at which frame rates or how much of a drop in frame rate would cause this VRR flicker. However, because lower frame rates have a longer frame time and more of a chance for the RGB values to deviate from their ideal value, this type of flicker is more noticeable with lower frame rates than higher ones. For example, there’s more of a chance of this flicker with frame rates between 50-70 than from 165-185, because there’s a larger variation in frame time.
The best way to avoid this flicker would either by using a frame cap or not using VRR at all, but neither of those are ideal solutions.

Incredible update that makes the bench much, much, much more useful. I’m a big fan of the new motion clarity image (and basically every other change you’ve implemented). Since I don’t think it’s mentioned, what’re the measurement tolerances for the response time tests? Knowing would help with interpreting those bench results better.
Thank you, we appreciate that! We use a +/- 3 RGB tolerance level for the response time tests, which you can read more about here.
