Our Verdict
Gigabyte G27QC
Samsung Odyssey G50D S27DG50
The Gigabyte G27QC and the Samsung Odyssey G50D S27DG50 are both entry-level 1440p gaming monitors. They have different panel types, each with their own pros and cons. For example, the Gigabyte has a VA panel with a higher contrast ratio for deeper blacks in dark rooms. However, the Samsung has an IPS panel with wider viewing angles. The Samsung also gets brighter, making it the better choice to use in well-lit rooms.
