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 option here, but its 144Hz refresh rate (compared to Dell's 60Hz) makes it a no-brainer for gamers. If you're serious about gaming, that smooth action is crucial. Meanwhile, the Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor offers stunning 4K resolution and deeper blacks with its 2000:1 contrast ratio, making it ideal for photographers and designers. In my testing, the LG's 2560 x 1440 resolution provides a sharper image than 1080p, while the Dell's 3840 x 2160 resolution offers notable detail for editing and content creation. The LG excels with fast 1ms response time, but you might miss out on some connectivity options that Dell packs in, like a built-in KVM switch and USB-C hub capabilities, which can simplify your workspace significantly. Key specs: Refresh: 144 Hz vs 60 Hz and Weight: 215.17 oz vs 234.22 oz.
Why compare these? The LG 27GL83A-B 27" UltraGear QHD IPS Monitor (mid-range) and Dell UltraSharp U2723QE 27" 4K USB-C Hub Monitor (premium flagship) represent different approaches to monitors. While they may appeal to different budgets, many buyers consider both options. This 2026 comparison helps you decide if the differences justify the price gap.
