you have to check your laptop gpu spec against the monitor's resolution. But I think mid to high end laptop from the last 5 years will be ok as long as you keep the refresh rate to 60hz.
Regarding those ultra wide, it really depends on what document you use most.
You prefer height or wide?
I change from 32" wide to 34" ultrawide before. After 2 years, I will be changing back to 32", because i found out myself actually prefer taller screen instead of wider.
size of ultrgear series Without Stand (WxHxD)
39" 21:9 = 35.0" x 15.9" x 7.8"
34" 21:9 = 30.9" x 14.1" x 6.6"
32" 16:9 = 28.1" x 16.2" x 2.6"
27" 16:9 = 23.8" x 13.8" x 1.8"
hmm... 25% wider than regular wide 32".
I concur. Using a LG 32" ultrawide, decided to switch back to widescreen after 6 months.
