I tried the 32” 4K, Samsung odyssey 49” ultrawide, 43” 4K tv, and settled on my current Dell 40” 5k2k ultrawide.

For me, the 32” is not wide enough (I use a Mac) and the 43” 4K tv is too tall (neck strain). The Samsung 49” is too wide and not enough vertical space. The Dell 40” is great—-it as tall as a 32” 4K but has 50% more horizontal space. Combined with Rectangle I can split it into 3x2 or 4x2 or 1/4,1/2,1/4 easily. It’s pricy but imo it’s worth it.
