I have a 2016 Macbook Pro 15 and would like to upgrade my 5 year old Thunderbolt display to the LG 5K Monitor. Users report problems with maintaining a stable connection to the monitor with laptop freezes, crashes, etc. Knowing the percentage of time this occurs would be helpful in terms of deciding whether to take the risk of buying a new monitor (and having a problem show up after the 14 day return window). No one at the Apple stores can answer this question. Any guidance would be appreciated. Thanks in advance. Roosevelt.
