It depends. If text contrast is a priority, VA provides better blacks. Personally I also can’t stand IPS glow and rather live with the VA off-axis gamma shift. OTOH, my favorite VA monitor is now 15 years old and there is no current replacement with the same picture quality. I’m hoping for more OLED monitors coming out.
IPS black imho better choice (I own one). VA looks very very bad with dark themes in IDE. Also, I do not know any Eyesafe certified VA's. I am sensitive to blue light and my eyes love Eyesafe certified panels.
Why is that? And what type is better and why?
IPS panels have the best color accuracy and viewing angles. VA can produce the best blacks but pixels are slow to change. TN are the cheapest and historically have the best refresh rates.
Among LCDs currently. Micro LED and OLED produce better blacks.
