LG 27GL83A-B 27" UltraGear QHD IPS Monitor vs Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor
The LG 27GL83A-B 27" UltraGear QHD IPS Monitor is the mid-range champ, while the Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor takes the flagship title. The key difference? The Dell's stunning 4K resolution at 3840 x 2160 vs the LG's 2560 x 1440. This makes the Dell ideal for photography and video editing, providing vibrant detail and color accuracy. In real-world use, the LG's 144Hz refresh rate crushes the Dell's 60Hz, making it a top pick for gamers. However, the Dell's 2,000:1 contrast ratio offers deeper blacks, which is crucial for professional work. So, if you need a gaming monitor, the LG is your go-to, but for creative tasks, the Dell shines brighter in many ways.
