Consensus
our Verdict
The HP E45C’s 44.5-inch screen is great for office productivity as it provides enormous screen real estate, making it the perfect substitute for a dual-display setup. It also boasts a wide range of inputs that make it ideal for both work and play, as its HDMI 2.1 ports are perfect for connecting it to the latest consoles, and its four USB ports allow for seamless connectivity to multiple external peripherals.
The E45C’s 178° horizontal and viewing angles are ideal for group viewing and screen sharing. Also, with a 99% coverage of the sRGB color gamut, the display makes the cut for color-critical work, and a 165Hz refresh rate coupled with a 3ms response time also yields it enough credence for competitive gaming.
