附一段 rtings 摘抄：
If you don't need all the extra features and the massive USB hub of the Dell U2723QE, and you're looking for the best budget 4k monitor, consider the Dell S2722QC. As it's a lower-end model in Dell's productivity lineup, it has fewer USB ports and features as it doesn't have a KVM switch, but it still supports DisplayPort Alt Mode on its only USB-C input if you want to connect your laptop. The USB-C port supports 65W of power delivery, less than the 90W on the U2723QE, but still enough to keep your laptop's battery alive while you're working. You can often find the S2722QC on sale at a budget-friendly price, but if it isn't on sale, the Dell S2721QS is another low-cost option that doesn't have any USB-C ports but still delivers the same great picture quality and performance.
