Monitor response times, advertised at 1ms / 0.3ms are apparently just marketing bs.

Would a TN panel marketed at 1ms generally have better input lag than a IPS marketed at 0.3ms

Seems going by the spec sheet is pointless.

Im looking for a 24" - 28" 240hz FHD/QHD monitor with the quickest response time, advertised these days quickest ive seen is 0.1ms

Advertised response times are usually an arbitary gray-to-gray pixel response, not a measure of input lag.

Most modern displays have very little in the way of processing lag (assuming native resolution and latency reducing features are enabled), so scanout + pixel response is going to be the bulk of display latency. OLED will be the fastest, beyond that it's a pretty good mix of LCD tech.

Example:

In general, you should be able to find reviews that do actual latency measurements for most displays.

Input lag is completely different from pixel response time.

Response Time is the time it takes for the pixel to transition from one color of gradient to another.

A slow pixel response time leads to blurry motion image. Traditional VA panels as an example is known to have dark smearing because the pixel is not fast enough to be able to transition from one gradient to another.

Input lag on the other hand is the time it takes for the screen to register input changes.

As an example, most TVs are known to have high input lag which is very noticeable especially when playing retro consoles. Your inputs are delayed.

For good motion performance, you want a monitor that has: 1000 / refresh rate = pixel response time

Quickest pixel response time is gonna be OLED by far. As far as input lag, OLED monitors generally have that well under control as well but TVs have problems.

Neat, some new entries to the scene. Let's see how it compares to my ASUS XG27AQM.

Apparently according to RTINGS (the only place I could find a measured input lag value), it's 3.2 ms.
So basically better than everything on that list except the newest OLEDs ASUS put out.

I made a good investment that I won't have to change for a while :)

RTING results aren't comparable to that picture.
RTINGs input lag is only the total time of processing lag/refresh lag whereas the picture is a total including the response time(how long a pixel takes to change colors)

Extrapolating the other info on RTINGs your monitor would be near the bottom of the chart here.
Total Response Time 7.3 ms + 3.7 ms Input Lag = 11 ms on that chart

OLEDs are still much faster than, motion clarity isn't even close. Even the best IPS/TNs are still a ways behind in clarity vs OLED unless they have significantly higher refresh rates.

As for your investment, as long as you are happy with the picture it really doesn't matter at the end of the day. You won't miss something you haven't experienced

Yeah, I figured there was more to the equation than just that. There's a lot of complexity with monitors.

If I hadn't basically retired from competitive gaming, I might've considered another monitor upgrade. But I have family, work and non-gaming hobbies to tend to now.

My 240Hz Samsung G7 definitely had better motion clarity than my 120Hz LG C2 OLED, mostly because it was double the refresh rate. However, they weren't that far off even with both at 120Hz...the OLED was better, but it wasn't a night and day difference.

In general, as long as the actual transition times are already well within the refresh window, even a moderately higher refresh/frame rate is probably going to be more noticeable than major improvements to pixel response, in terms of motion clarity. Problem is that a lot of high refresh rate LCDs can barely do justice to their refresh rates and some fall well short.

Isn't the G2G pixel response time on the OLED's almost unbeatable?

Yeah when LCDs are 2x the refresh rate vs OLED it's close. If they are equal in refresh rate it's much more apparent.
I came from a G7 and I have the AW3225QF 240Hz 4K one. Night and day difference in clarity.

The G7 was good(in response time) in bright colors but introduce dark scenes and it was bad. But that's an inherit issue with all VA screens. Oled has no issues regardless of the scene color/

I play a lot of tarkov and that game has many dark scenes and it really made me want to get rid of the G7. Plus the terrible flickering was extremely annoying.

Yes, OLEDs response time is nearly instant. No other current tech beats it or gets close unless other techniques like backlight strobing is introduced.
