Notebookcheck and UltrabookReview are both known for highly detailed reviews, including detailed measurements of display performance, so if you find a review of the Vostro 5490 with the same display option you're looking at on that site, I'd read it. But since again understanding the overall technology won't necessarily tell you how good the specific panel in that system is, you might want to try to find a detailed review of that specific system with that specific display option. Going back to the question of "WVA", it's possible that's just a brand-specific name for some variation of VA technology, similar to how there's a "PLS" panel type that's essentially some brand's variation of IPS (I think Samsung?). There are many articles on the Internet that go into more detailed comparisons between TN, VA, and IPS panel technology, although of course specific implementations will always have some variation, meaning that there are great IPS panels and terrible IPS panels, for example. However, VA typically offers better black levels and less backlight bleed or "glow" compared to IPS panels. It has better color accuracy and viewing angles than TN, but it's not as good in either of those things as an IPS panel. ![]() I'm not sure what the "W" stands for, but a "VA" panel is sort of a compromise between TN and IPS.
