basically anything that doesn't have a big enough market won't take off.
3D for example in tv's. Small OLED's will never take off when you can make an LCD for less than 1/4 of the price.
1080P is also being phased out of consumer tv's with everyone focusing on 4K so i doubt pc enthusiasts want anything less than 4k these days.
Basically there isn't a big enough market for a 24" 1080p OLED. Prices would also be ridiculously high. Which makes that market even smaller.
The U2414H can be had for £140 (WOST). It's hard to beat that tbh in terms of quality and 1080p. It's only 60hz but IMO that is more than adequate. Movies at the cinema are only 24fps.
I had a 120hz/140hz TN monitor and I sold it and went back to 60hz but IPS.
If you think it would be successful it's already clear there is a gap in the market why not build these monitors and try and sell them? Point being they don't do enough to justify the cost of them to be marketable to enough people to make it worthwhile.
Unless you want to spend $5K. A grand total of zero of those will be sold I imagine and then that project will be thrown out with plasma.
There has never been a technology that had a big market from the day 1. Please read this:

Your whole post rests on the assumption that OLED will never become price-competitive with LCD tech. But OLED is not some fringe technology from a random company. On the contrary, there's a huge push from all the big market players to drive this technology forward. If the technology were inherently so expensive without any room for improvement, then why would they invest so heavily in it?
As for 3D:
It's a periodical fad, it always takes off for a few years, then lays dormant for 10-15 years (or was it 30...?), and raises its head yet again. You must have missed the last wave, as 3D indeed took off and faded out, already. But actually, from the looks of it, now that periodic behaviour even seems to change, as there's a chance that VR will force the new wave back faster than before. Then again, there's indeed a chance it will stay as a smaller wave inside the computer market, not even reaching the TV market.
As for 1080p:
1080p as a whole won't be going anywhere anytime soon. At least here in Finland, most channels are still shown in SD, and HD being more of a luxury. What you see here in the forums is indeed an enthusiasts' point of view. And even here, 4k is still quite low-key. It will take quite a while before 4k reaches mass adoption.
And once again, with regards to plasma:
Plasma died because it couldn't keep up with the competitors. OLED is in a totally different situation. OLED is the "new tech". So, on the contrary, there's actually a chance that OLED will eventually replace LCD, like LCD replaced plasma and CRT.
