Yes, that's unfortunate,
A lot of people want it to exist, but if they were to make one, people would stop buying their high end products, and their current TN panels would be washed away, because in terms of input lag and pixel response time, IPS and TN are about even. The best PC monitor that I think gets little to no attention, is the FG2421 by EIZO. It's using a VA panel, which in both games and movies is superior to that of IPS, however. The color reproduction is slightly below IPS, but way above TN.
All the best!
