Our Verdict
Samsung CHG70
Samsung C34F791/CF791
The Samsung CHG70 is much better than the Samsung C34F791/CF791. The CHG70 has much lower input lag, supports HDR, and is equipped with local dimming to make blacks even deeper. You can position it according to your liking and you'll enjoy it in every use. The CF791, on the other hand, is larger, giving you more screen area and more resolution to work with.
