The U2790VQ is a 27″ 4K IPS display that comes with a 5ms GTG response rate. Their monitors are a bit more stripped down, which is how they get lower costs, but the displays in ther monitors are decent enough to where they are viable options for budget-oriented users. However, they are starting to become more popular by offering cheaper monitors than their competitors. AOC is a well-known manufacturer of monitors, but they haven’t been around as long as some of the bigger players. If you’re looking for an affordable 4K monitor that has an extemely thin border, then you might want to consider AOC’s U2790VQ. So, if you’re looking for a smaller 4K monitor, that would be the best route to go out of the other options on this list. It’s also worth mentioning that you can get the 24″ version of this monitor for just under $250. Though, if you’re not a gamer you’d probably prefer the IPS panel instead, and in that case the LG 27UD58-B would be the better option. Ultimately, while both the LG 27UD58-B and ASUS VP28UQG are solid options, we felt the faster response time and slightly larger screen helped the ASUS 4K monitor stand out a bit more. If you’re a serious competitive gamer, you may want to opt for the fast 1ms GTG response time on the ASUS VP28UQG instead of the 5ms GTG response time on the LG 27UD58-B, although most gamers likely won’t be able to tell the difference between the two. The IPS panel will help for wider viewing angles, though, so there are trade-off costs. It does have a slower response time, though, but that is due to the fact that it sports an IPS panel instead of a TN panel. Like our top pick, the ASUS VP28UQG, the LG 27UD58-B comes in at just under $300 and also features AMD’s FreeSync technology. Our runner-up pick is LG’s 27UD58-B 27″ 4K monitor.
