The UltraFine 40WT95UF is LG's latest 5K2K monitor aimed at businesses. Built around a 5K2K and 21:9 IPS Black panel, the UltraFine 40WT95UF also offers a 120 Hz refresh rate for smooth visuals and Thunderbolt 5 connectivity for the first time in a 5K2K monitor.https://www.notebookcheck.net/UltraFine-40WT95UF-LG-unveils-new-5K2K-and-Thunderbolt-5-with-120-Hz-refresh-rate.1030192.0.html
Nothing unfortunate at all about the new monitor not being OLED. For productivity OLED still sucks, and IPS black is perfectly fine. You can get the 45" if you must have OLED. Pixel density in the 40 model is much nicer, matching 4K 32" monitors.
My next monitor will be 5Kx2K in 39-40" size. Unless OLED can improve burn-in to the point you can get a 7 years warranty, not interested.
