I was really thinking OLED would be the absolute cure to my issues I've been having over the past few years but it hasn't solved it. I've upgraded my computer since back in the day when I had this issue on my old monitor (Asus pg258q) thinking it could be hardware but I'm not sure it is. The weird phenomenon not sure if anyone has also encountered this but it seems whenever a game I play has a game update IE new season or new patch my game runs silky smooth and I see no ghosting at all but as soon as I reboot the game its back to the unsmooth gameplay linked above. Any settings at all or recommendations will be very much appreciated and if a fix or make it ANY BETTER can be found I will be eternally grateful for you and in debt to you
Let me attempt to have a crack at this topic.
I have an intimate familiarity with this topic, given that 75%+ of my income in 2023 was on OLED research, and I can be a more confident authority in understanding why people observe certain things with OLEDs. So It's totally understandable confusion and I'm pretty happy to help with this matter. I will improve the rising tide of Internet knowledge by writing more articles on this matter during 2024, but for now:
Firstly, let's cut to the chase: Retina refresh rate isn't till well beyond 1000fps 1000Hz
And yes, you need both frame rate and refresh rate to be in quadruple digit territory to brute-out a lot of motion artifacts you are seeing today. Retina refresh rate for desktop monitors is not until >1000Hz. So, you ARE going to see refresh rate limitations for a long time.
Sorry to be the bearer of bad news, you're not going to fix "differences between displays and real life" at contemporary three-digit refresh rates. People who are sensitive to stroboscopics/etc (calling it "ghosting") will need to enable GPU Motion Blur Effect (add blur to fix this) or wait for quadruple digit refresh rates...
Next, Ghosting Confusion is Common
There are many different accidental descriptions of what people say as "ghosting". Displays behave differently whether you're fixing eyes or moving eyes:
- Stationary eye, stationary object,
- Stationary eye, moving object,
- Moving eyes, stationary object,
- Moving eyes, moving object.
Usual Terminology of Ghosting: Ghosting = Asymmetric Motion Blur
Here's some observations that I need to give you a heads up with:
- At Blur Busters, the terminology "ghosting" is considered asymmetric motion blur, as follows.
Observe the yellow blurs more towards left than towards right. Basically a "longer trailing motion blur" effect, is considered ghosting because ghost is like a vision of the past, ala spooky ghosts (RIP, Halloween, 1800s), which is why we call it "ghosting", an afterimage of the past that lags BEHIND the motion. So ghosting is only used to define asymmetric motion blur, where the past image is still visible.
This is probably not what you are seeing, although early firmwares on certain OLEDs do exhibit similar ghosting artifacts (streaking in dark backgrounds) due to OLED quirks and OLED overdrive (yes, some OLED also use overdrive algorithms too, although much more lightly than LCDs do). It's just at an order of magnitude smaller than LCDs generally.
Disambiguation Time...
- 1. Stutter Amplification of Fast Pixel Response
Some people confuse ghosting with stutter, so I mention this...
OLEDs stop stuttering at 75fps+, while LCDs stop stuttering at 50fps+
This is because LCD GtG was so slow, that the GtG blurring/ghosting "hid" stutters. OLED pixel response is so freakingly fast, that you will see smaller stutters at higher frame rates more easily. So you need more frame rate for your higher-quality faster-responding display. This phenomenon is described at:
EXPLAINER: Why Do OLEDs Stutter More At Low Frame Rates?
FIX: Increase your OLED Frame Rates To Compensate
.
- 2. Stroboscopics Confusion Factor
Some people confuse ghosting with stroboscopic / phantom arrays, so I mention this too...
Jorim already told you about this, and this is just the "mouse arrow" factor, and already explained in lovely images at The Stroboscopic Effect of Finite Frame Rates
FIX: Turn on GPU Motion Blur Effect in Your Games
.
- 3. Persistence Motion Blur
Some people confuse persistence motion blur (symmetric motion blur) with ghosting, so I mention this too.
This is simply an artifact of pixel visibility time, which can only be fixed by good strobing or more frame rate. These are two valid approaches to reducing display motion blur; as illustrated by these two diagrams:
FIX: Get as much frame rate as possible on an OLED. Or if your display has BFI/strobe, turn on strobing at shorter pulse widths. LCDs such as ViewSonic XG2431 via Blur Busters Strobe Utility can do an excellent job at strobing, but this will never fix stroboscopic effects -- that requires more framerate and/or GPU blur effect to be added.
Remember, ghosting confusion is pretty common, and sometimes you will see ghosting only with moving eyes, and other times, only with stationary eyes.
-> If you only see "what you think is ghosting" while your eyes are moving, it MIGHT be item 3.
-> If you only see "what you think is ghosting" while your eyes are stationbary, it MIGHT be item 2.
Hope this helps you remedy your vision sensitivity!
It's part of my 2024 speciality to educate/mythbust on these types of matters now, on these big rabbit holes.
