Iiyama's MVA3 displays are, to my knowledge, significantly in front of other LCD styles (e.g. TN, IPS) as far as contrast, especially from an angle, is concerned.

Unfortunately my desk's dear centerpiece, https://iiyama.com/gl_en/products/prolite-x4071uhsu-b1/ , has been EOL'd about 2 years ago, because I have been unable to find a replacement that's not worse, while staying in the 40~50" range. Any concrete suggestion would be greatly appreciated.
