It's not really a crapshoot in this day and age. RTings tests all the TVs they review for max Chroma sampling. These days many or most mid-range TVs (~$700-1200) support full 4:4:4 sampling in at least some capacity. Even some of the cheaper TCLs support 4:4:4 in "PC mode". In any case, reviews cover that stuff thoroughly so a little research goes a long way.

Mine is advertised as 1200:1 I think and it's often around the 1350:1.

I've posted rough numbers of 2x multiples, rough, not accurate for every damn panel ever on market that was and will be.

Same, while I can see and appreciate the higher contrast of VA over IPS at twice the contrast = half brightness black level, it's way too small of a difference to be worth the crazy tradeoffs one has to make when going with a VA. If it was 10x difference, then sure now we are talking something that's becoming worth it. On top of it all if they would make IPS with glow removing filter and local dimming? People would forget about VA in an instant... it's too good so they don't want to make it. Same with OLED, too disruptive.

There are pros and cons to all: TN, IPS, VA, OLED, ... one has to decide for themselves what trade offs they want to make.

by "some old junk", did you mean pretty much every IPS panel that tftcentral has reviewed, including AUO's newest 144hz 4k panel?

Again, you're waaay over-exaggerating here. There are maybe 1 or 2 outlier panels in gaming monitors with much over 1000:1, it is absolutely not common and 1000:1 is absolutely not "some old junk". It's brand new stuff. It's top of the line monitors. If we're going to use outlier measurements for IPS panels then we need to use outlier measurements for VA's as well, and there are a couple that are 4000:1 or better.

You're more than welcome to like IPS over VA, but you're misrepresenting the capabilities of a typical IPS panel.

I do think JackCY does over-exaggerate things a tiny bit. I could barely see the VA smearing in his comparison videos, and barely notice it while using the exact same model monitor that he took videos of. As mentioned before, I just like the way Samsung panels handle colors and sharpness, and it outweighs the to-my-eyes minor problems, so I keep the Samsung.

Yes, I know monitors can have their colors calibrated and sharpness adjusted, and my impressions are completely subjective, but it's just what I like. :shrug:

Can you read? I've said right there even in your quote: "Yes there are some bad panels, new panels, that have low contrast for an IPS that is also noted in their reviews, 1070:1, advertised as 1000:1 so what do you expect?"

Well all the IPS I've used and measured are in the 1100:1+ mark be it old or new. Yes there are crappy IPS with close to 1000:1 and there are some that do even 1500:1. Same as VA 2000:1 or 6000:1+. Or TN maybe even sub 500:1 but also 1000:1.

I don't care about the XV273K, people have unrealistic expectations, like it's gonna use some miracle panel, the whole 4k 120Hz is rubbish right now, oh wait they sell it as 144Hz pardon me, hell some modes they will only 98Hz in fact.
TFTC reviews barely 1 monitor/month.

Wanna say IPS is more averaging 1100:1? Why not, it's only an illustration that TN is roughly 2x worse than IPS and that is 2x worse than VA when it comes to black level = contrast.

M270DAN2.x from 4.12.2018 review:


And you've said:

So what is M270DAN2.x then? At 144Hz native support and all monitors sold with it support 144Hz+? It's not gaming panel/monitor just like 1080Ti isn't a gaming card because it uses the same chip as Titan which also isn't a gaming card?

They do exist since about 2014/15 if you count 144Hz as a gaming panel/monitor.

I'm not saying they don't exist, I'm saying that they aren't typical like you keep suggesting that they are. Case in point: you cling to one monitor to make your case, whereas I see the fact that you only have one monitor to support your case as proving that it's an outlier statistic. You're going to find about as many VA panels over 3000:1 as you are IPS panels over 1100:1 so for you to say that 1400:1 is some sort of standard IPS contrast ratio is either very misinformed or just downright disingenuous.

Everyone else in here is just trying to get usable information about IPS and VA panels, whereas you seem like you're on some sort of crusade to make sure no one considers a VA panel.

Considering it's the only and most common gaming IPS, what other can we choose LOL. It's not like there are 10 144Hz IPS panels to choose from, there is one, it's M270DAN2.x. Now there is also M270QAN2.x which is the 27" 4k. Everyone would be happy if there were more gaming panels aka 144Hz+ but there are only very very few.

Not using gaming panels and looking at any of that technology there is a range and an average. IPS on average is certainly above 1000:1 contrast for monitor sized panels.

LOL crusade, for what I don't get anything back, want to use VA use it buy it I never said not to, if you like it and are OK with the trade offs you have to make why not. Each LCD type even OLED has trade offs. For me the poor viewing angles, endless smearing from slow response times on out of blacks and other VA typical issues are not acceptable. They are to you? Buy a VA if you want to. Hell I bought 3 different VA panels by now with 144Hz, only one was worth anything. Add to that the AUO AHVA and that's all 144Hz 1440p panels in existence (in shops before Q4 2018 worldwide, or Q1 2019 in EU/US) right there for IPS and VA, seen and used the TN in that resolution and refresh but didn't buy it as it was horrendous. So what "gaming" panels are we talking about? Still unavailable Innolux in XV272U? Did you import one from Asia to tell us about it? Or completely unknown LG IPS 144Hz? Or some magical great VAs you know about?
