A tiny and personal test of some EVF

Theoretically, people can't see any refresh above 60 Hz, which is the standard for computer monitors for a long time, but if that is the case, why are gamers looking for higher and higher refresh rates?

These IPS monitors had backlights. On OLED, there is no backlight.

In your first post, you mentioned that the Nikon Z6II displayed an erratic image when turning. This is like panning while gaming and experiencing screen tearing.

Screen tearing occurs when your monitor's refresh rate and GPU's frame rate are not synchronized. It's characterized as a horizontal split at one or more places of the image.

Except that, when you pan in a game, the lighting conditions remain constant, however the GPU's framerate changes.

In a mirrorless, the exposure changes when you pan, for example panning from a bright table lamp to a darker corner of the room. Therefore you are looking at a video feed that may change from 1/24sec to 1/60sec to 1/125sec as you pan.

Its because of these issues that I'm researching the Pentax K3 mk III. Otherwise I would really like a Lumix GH6.

The 60 Hz is a myth. It is based on old measurements. And that is why TV have usually have higher refresh rates. Many people can see more.

The main problem when panning in games is neither flicker nor tearing. The main problem is the lack of smooth movement. Lets say that I pan the entire monitor width in one second, which is totally possible for a gamer. Then things are moving e.g. 2400 pixels in one second. During this second 60 sharp images are shown. The offset between those sharp images is then 40 pixels. This means that sharp stuff with high contrast looks like several images instead of a smoothly moving image. Some games fix this by blurring the movement.

And this problem, of course, also can happen in an EVF. You turn around and the refresh rate is right now only 1/10 second. You see several images instead of a smooth moving image.

This will happen if you use "exposure preview" for the EVF. But that can be turned off on most mirrorless camera, and then the refresh rate of the EVF will not be limited by the shutter speed used. EVF will use the same refresh rate and brightness regardless of exposure settings (unless it is extremely dark conditions).

But there may be other things that can affect the experience too. Like what type of light bulbs used in the room. You may get interference between refresh rate of the EVF and frequency used for the light bulb. LED lights is probably the worst in this regard, or maybe even worse if there is a mix of different light sources.

And this combined with a stabilized EVF can get really strange effects.
