Hey @rahuljawale which monitor did you go for ? I am also in similar situation. Seems like the price for Dell U3423WE has came down to 85K on amazon. Which one did you purchase ?
I went with LG 34WQ75C. It is perfect except that the 3800R curvature takes a while to get used to. Dell's 1800R is more natural. You do not need time to adjust to 1800R. The Dell monitor also has better connectivity. But I solved that problem by adding ORICO USB3.0 HUB.
