Our Verdict
AOC CU34G2X
Samsung Odyssey G50D S27DG50
The AOC CU34G2X and the Samsung Odyssey G50D S27DG50 are both budget-friendly gaming monitors. There are a few differences between them, though, as the Samsung has an IPS panel with better motion handling and less smearing, and its wide viewing angles make it a better choice to use if you need to share your screen with someone else. However, the AOC has a wider screen, so it offers a more immersive feel, and it has a VA panel with a higher contrast ratio, so its picture quality is better. The AOC also has a few extra perks, like a USB hub to which you can connect your devices.
