Our Verdict
Acer Nitro XV340CK Pbmiipphzx
Gigabyte G34WQC
The Acer Nitro XV340CK Pbmiipphzx is a bit better than the Gigabyte G34WQC. They both have the same size, resolution, and refresh rate, but the Acer has an IPS panel that provides much wider viewing angles. It also has better gradient handling and faster response time with less overshoot. On the other hand, the Gigabyte has a much higher contrast ratio, a better HDR color gamut, and gets brighter in SDR and HDR.
