Why do some high refresh monitors have blurry image and others are crispy?

I assumed that the higher refresh rate, the crispier and smoother the image, but I was wrong.

 

I was watching a video that was comparing two monitors and he showed that issue on one of them.

 

Without looking for reviews, how do you know if a high refresh monitor has (or not) crispy image?

 

Does the CPU and GPU play a part on this? (assuming that perfomance isn't an issue, i.e easily go above the refresh rate in terms of FPS)

It really depends on monitor response time.

 

"1ms" is a lie and I always ignore their advertisements. I only stick to trusted reviewers.

 

Overall IPS and TN have decent response time so there's a bit of blur, OLED has very fast response time that would look crisp, and on the opposite end VA is slow so everything look like motion blur turned on. To answer your question without looking at reviews, not getting VA is probably the best answer (some exceptions like Samsung G7 has fast VA response time, I wish this would become the new norm). Unfortunately there can be good IPS and bad IPS, that's when we need to look at reviews to see their response time. 

 

Finally it depends on motion overdrive settings and the relationship with refresh rate. After seeing multiple reviews 'default' is usually the safe option and can be adjusted faster, but too fast can lead to overshoot (like inverted motion blur).

TN may have fast response but I've yet to find one that looks decent although I'm a PQ snob currently on a 48in OLED.

They is no reason buy TN panel anymore. TN is the worst Display panel ever manufacturer. For now IPS and VA and OLED can go superb fast, they is even no reason to get TN.

 

Please 100% avoid TN for your next purchase.

OLED has fast response time, but not at low brightness, worse is if the pixel is in off state and needs to be bright. It's call black smearing.

 

If your phone has an OLED display, use it at night to see the screen at its minimum brightness, use dark theme, and now scroll through content. Response time will be horrible. Now, this is a phone, so power saving comes first, and high speed refresh rate isn't a priority. So LG TV isn't as bad, phones is kinda the worse case, but it is so bad, it is easy to see. But, point being, it is an issue on all OLEDs.
