Dell S2721QS 27" 4K UHD IPS Monitor vs GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor
The GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor is the better buy for most gamers. Its 144Hz refresh rate crushes the Dell S2721QS 27" 4K UHD IPS Monitor's 60Hz, making fast-paced gaming a dream. In real-world use, that means smoother gameplay and less motion blur, which is crucial for competitive gaming in 2026. Meanwhile, the Dell S2721QS excels in text clarity with its 4K resolution at 163 PPI, perfect for photography and media consumption. However, if you're focused on gaming, the limitations of its refresh rate and lack of USB-C connectivity make it hard to justify over the GIGABYTE. With the M28U's built-in KVM switch, you can easily switch between devices, enhancing your multitasking experience. Key specs: Display: 27" vs 28" and Refresh: 60 Hz vs 144 Hz.
Why compare these? Both the Dell S2721QS 27" 4K UHD IPS Monitor and GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor are mid-range monitors competing in the same market segment.
