How far away are we from 120hz+, ips, 1ms or less response time, monitors?

The first 2 ms response time TN came out in 2005 and the first 1 ms response time TN came out in 2010.
I think the fastest IPS is still only 5 ms. You probably have a long wait if they ever even get that fast. OLED will probably completely replace LCD before it happens.

I would think something entirely new will happen before this. 1ms has proven incredibly hard for manufacturers of IPS. They'll get close to 4ms and it gets out of control real quick. All IPS needs is 120Hz. 4-6ms is fine for pixels. Something other than LCD would be nice instead of chasing matrix switching times.

IPS can get to 2ms GtG depending on measurement methods. And are we talking real measurements or manufacturers claims? Most TN's rated at 2ms are more like 3-10ms. Most indicated speeds are blatant lies.

If you did 120hz on a 5 ms LCD then for each frame you would have 5 ms of blurry pixels then 3 ms of correctly colored pixels. That is a lot of blur.

I don't think it'll be until around the early 2020's that OLED's will beat LightBoost motion clarity (fixes the LCD sample-and-hold problem) while also simultaneously being bright enough and inexpensive enough.
See:
Why Do Some OLED's Have Motion Blur?
Even instant-response-pixels have motion blur, if there are other weak links (e.g. sample-and-hold). Motion blur is not caused by pixel response time alone, but ALSO by the sample length (sample-and-hold problem). Hopefully by 2017 or 2018, we will see professional OLED's (~$1000) that eliminate motion blur as completely as LightBoost can today. But they still won't be inexpensive until later on than that. The LCD pixel persistence barrier was finally broken recently (high-speed video of pixel persistence successfully being bypassed); LED backlights can switch as quickly as OLED. Right now, it looks like we have more than half a decade of LCD improvements before OLED's can successfully take over. I'd imagine native-240Hz LCD's and IPS stroboscopic backlights to be far cheaper to do than OLED.

This is Chief Blur Buster of BlurBusters.com....
Now that pixel persistence is less than a refresh, it is now technologically possible to keep those pixel transitions in total darkness.
e.g. 7ms of total darkness and 1ms of stroboscopic backlight flash.
See high speed video of pixel persistence being successfully bypassed.
The backlight is turned off while waiting for pixel transitions (unseen by human eyes),
and the backlight is strobed only on fully-refreshed LCD frames (seen by human eyes).
The strobes can be shorter than pixel transitions, breaking the pixel persistence barrier!.
That's what LightBoost does; to make possible the LCD with fully CRT-clarity motion. This is superior to yesterday's scanning backlights in existing technology and superior and clearer motion than motion interpolation; but without the input lag of interpolation. There are other types of stroboscopic backlights (other than LightBoost, which is just an nVidia trade name of their own version). It's only recently that such backlight technologies can now get us an order-of-magnitude elimination of motion blur & in a game-friendly manner.
For such a technology to work on IPS LCD's, you need to squeeze pixel persistence into the time period of a blanking interval between refreshes. Most intervals between refreshes is just a millisecond or less. So the blanking interval has to be artificially lengthened (either from the graphics card or internally within the monitor), and each LCD refresh fast-scanned (e.g. refresh the panel in 1/500th second), then give a healthy amount of time (e.g. 5 or 6ms) for pixel persistence to settle down. LCD panel makers have been working on these technologies to make 3D stereoscopic operation possible on HDTV displays; and 3D shutter glasses have the exact same requirement (fully refreshed frames for shutter glasses operation). So active 3D compatible panels are excellent candidates for motion blur elimination for 2D.
