When somebody is able to create OLED monitor than can display static image without fear of permanent damage I'm all in. Until that, IPS is the best long term solution. Of course, if you're rich enough, you just get a new OLED monitor every year or more often as the image detoriates and don't mind the costs.

@Time.TraveI.0 VA display have acceptable color and great black level. The gamma shift on vertical movement is may be a problem depending on your usage pattern but the real killer is very bad pixel response time. VA pixel response from pretty dark to medium dark often takes about 30-50 ms whereas IPS and TN panels require 10 ms for bad panels and maybe 4-5 ms for good panels. The "1 ms pixel response" is just marketing lie on anything but OLED panels. If you can render more than 20 fps (as in your fingers and toes) you'll be limited by your panel's pixel response time on VA panels already!

@Time.TraveI.0 See the RTINGS test results for those monitors instead of trusting the marketing material. The pixel response table shows about half the table in red for really bad overshoot on max refresh rate. The 60 Hz "Standard" (minimum) overdrive setting results in not-too-bad overshoot (still over 10%) and total response average time is 13-15 ms and worst case pixel response is way over 20 ms. And there's no overdrive setting that wouldn't result in heavy rendering artefacts; the scale for overdrive basically goes from mininum "too much" to "even more" and "extreme". So those have all the typical VA panel problems but Samsung tries to hide slow pixel response time issues with badly implemented overdrive. With a superbly implemented overdrive it might be possible to have an acceptable VA panel but Odyssey G9 (neither model) doesn't seem to be such a display. Note the worst pixel response time of 20 ms. That basically says that the max fps this display can render nearly correctly is 1000/20 or 50 fps. And even there you'll see heavy flickering because of the heavy overshoot. Compare that to LG 27GN800-B which has average pixel response time of 7.4 ms and worst case response time of 10.3 with ZERO overshoot (that is, overdrive totally disabled which is the setting that I use because I hate seeing those overshoot artefacts). Note that this display can correctly render all frames at 1000/10.3 or 97 fps and in most cases 1000/7.4 or 135 fps.
