KOORUI 24E3 165Hz Gaming Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The KOORUI 24E3 165Hz Gaming Monitor is the budget option here, designed for gamers who crave speed. It boasts a blistering 165Hz refresh rate, perfect for fast-paced gaming. In contrast, the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor shines with its unique 16:18 aspect ratio and stunning 2560x2880 resolution, making it ideal for creative professionals. In my testing, the KOORUI offers a 1ms response time, ensuring no lag during critical moments in games. However, the LG's Nano IPS panel covers 98% DCI-P3, delivering unmatched color accuracy that's essential for photographers. If you need a monitor primarily for gaming, the KOORUI is a no-brainer, while the LG is the better pick for design work or multitasking in 2026.
