VA technology by its very nature is ill suited to fast refresh. The pixel structure that give it it's higher contrast ratio means it can't switch as rapidly as TN or IPS. So VA panel all have a smear/dark ghosting effect. Not too bad for me as I don't give a fuck about 144hz, but it defeats the entire purpose of fast refresh monitors. VA panels also have shite off angle viewing and gamma shift which can crush blacks with head on viewing. Fast refresh exists because the underlying technology of LCD is dogshit, they have to push these absurd frequences to counter the abysmal pixel response rate.
The fact you're mentioning 3000:1 contrast as some kind of benchmark says it all. Bias lighting? why don't you get a torch and shine it directly onto your screen? that'll improve the percieved black level as well... Ohh wait no it won't, because 90 percent of monitors have an anti glare coating which adds at a cataract over the image.
There are quality VA panels now with very low response times, and high refresh helps tremendously as well, making the smeary blacks issue much, much less of a problem. Not eliminated obviously, but not anywhere near as bad as it used to be. If your only standard is OLED blacks and you refuse anything else though then no, it's not going to meet your expectations. However I'm talking about PC monitors, not OLED TVs, so you're comparing apples and oranges. OLED monitors are like $5,000 still, and have their own flaws. I do look forward to them being more mainstream on PC.
