HP E45c G5 44.5" Black 2023

★★★★☆ 3.8 (13)

The 44.5-inch Double QHD VA panel with a 165Hz refresh rate and FreeSync Premium eliminates the need for dual monitors while keeping motion smooth. An integrated KVM switch and USB-C with 55W power delivery streamline a multi-device setup, though its 14.6 kg weight anchors it firmly to a desk. This display is best for financial analysts and multitasking office users who need to view massive spreadsheets or multiple sources simultaneously on a single seamless screen.

What owners think

The Word on the Street

3.8/5 (13 reviews)
👍 Owners consistently call this the perfect replacement for a clunky dual 24-inch setup, loving the seamless, bezel-free view.
👍 The built-in KVM switch is a huge hit, making it dead simple to control two computers with one keyboard and mouse.
👎 A common gripe is that the out-of-box setup guide is nearly useless, leaving people to fend for themselves to unlock all the features.

The proof

Performance

We were genuinely surprised by how well this VA panel handles motion. With a 165Hz refresh rate and FreeSync Premium, it's way smoother than any office monitor has a right to be. The 3ms response time keeps ghosting to a minimum, making it totally viable for some after-hours gaming, even if it's not going to dethrone a dedicated OLED gaming display. The real star, though, is the sheer desktop space. Having a document, a spreadsheet, and Slack all open at once without overlapping windows is a workflow revelation.

vs Competition

The obvious competitor is the Samsung Odyssey Neo G9, which is wider at 49 inches and packs a more dramatic 1000R curve, but it's also significantly more expensive and leans harder into gaming. For pure productivity, the Dell UltraSharp U4025QW is a strong alternative with a sharper 5K2K resolution and an IPS panel for better color accuracy, but you sacrifice the high refresh rate and that ultrawide 32:9 aspect ratio. If you want one screen to rule them all for work and play, the HP is the smarter, more balanced pick.

Price

Value & Pricing

Pricing on this thing is all over the map, with a wild spread from $999 to $2799 across vendors. At the low end, it's a steal for the screen real estate and KVM features you're getting. At the high end, you're getting fleeced. If you're paying more than $1100, you're doing it wrong. Newegg currently has the best deal we've seen, so start your hunt there.

Overview

The HP E45c G5 is basically the ultimate dual-monitor killer for your desk. It wraps a massive 44.5-inch, 5120x1440 canvas around your field of view, giving you the screen real estate of two 24-inch QHD monitors side-by-side without the annoying bezel in the middle. The one thing to know is that this is a productivity beast first, with a built-in KVM switch and tons of connectivity, that just happens to be surprisingly decent for gaming on the side.

Common Questions

Q: Can I connect two computers and use them at the same time?

Absolutely. That's the whole point of the built-in KVM and Picture-by-Picture mode. You can have your work laptop and gaming PC on screen simultaneously, controlling both with a single keyboard and mouse.

Q: Is this monitor good for gaming?

It's surprisingly solid. The 165Hz refresh rate and FreeSync Premium keep things smooth, and the 3ms response time is fast enough for anything but the most competitive esports. Just don't expect OLED-level contrast.

Q: Will text be too small to read at this resolution?

Out of the box, yes. You'll want to set Windows scaling to 150% to make text comfortable. It's a quick fix, but it's basically mandatory unless you have superhuman vision.

Who Should Skip This

If your heart is set on a single, immersive gaming display with deep blacks and a tight curve, this isn't it. The VA panel is good, but a QD-OLED like the MSI MPG 271QRX will blow it away in HDR and response times. Go grab one of those instead.

Verdict

If you're drowning in a multi-monitor mess of cables and bezels, the HP E45c G5 is your lifeline. It's a top-tier productivity monitor that streamlines your entire setup with a brilliant KVM switch and a massive, smooth display. The poor instructions and need for font scaling are minor annoyances in an otherwise fantastic package. For anyone juggling two computers and a dozen windows, this is the monitor to get.
