I cannot decide on which computer monitor to buy for a 2013 Mac Pro that I will be getting soon. Either way, I will still have to wait until next month to get a custom configured Mac Pro, which will be my very first custom Mac. There is a rumor going on that says there might be a new, new Mac Pro. Until then, I am saving up. I am looking at several computer monitors. I would like one Ultra Wide and one 5K. For the Ultra Wide, I was thinking of going with the LG 34UM88-P with TB. I am not sure if I am able to use the Thunderbolt connection/port as a display connection and not a data connection. There are also mixed reviews on the monitor. As for 5K, I was thinking of either the Dell UP2715K or the LG UltraFine 5K.
