Our Verdict
Samsung Odyssey G55T C34G55T
HP OMEN 34c
The Samsung Odyssey G55T C34G55T and the HP OMEN 34 are both good ultrawide gaming monitors. They share many similarities, but there are a few differences too. The HP gets brighter, so it's better to use in a well-lit space, and it has better ergonomics that make it easier to adjust. The HP also has better motion handling, but each monitor has smearing with fast-moving objects. One plus that the Samsung has is that it downscales 4k signals, which the HP can't do, making it a better choice for console gaming.
