A:Answer It's a VA panel. Sources incorrectly stated that most sizes were IPS, but this is untrue (it may apply to non-Us TV's or something, idk). Mine is definitely a VA, and even rtings confirmed that it's a VA panel (the review is for 55", but in the comments they checked the pixel structure of the 43" and verified that it was VA).
I don't get why Sony won't just tell people though. It would be a lot easier than making everyone wait for other reviews and any other brand will tell you that information. I love their products, but it just makes no sense for them to choose not to disclose the panel type to people interested in buying their products.
