Our Verdict
HP OMEN 34c
Samsung Odyssey G50D S27DG50
The HP OMEN 34c and the Samsung Odyssey G50D S27DG50 are different types of gaming monitors. The Samsung is a 27-inch monitor, while the HP has a wider 34-inch screen, offering a more immersive feel. They also use different panels, with the Samsung having wider viewing angles and the HP having a higher contrast ratio for deeper blacks in dark rooms. While the Samsung has blur with fast-moving objects, it has less black smearing than the HP.
