TechRadar Verdict

Though the price is high and the ergonomics are limited, using the HP E45c G5 is an experience that’s much more immersive than the typical monitor thanks to its wrap-around ultrawide curved screen. It’s also amazing for multi-tasking whether you’re using two sources, or just want to spread out across several windows for a more streamlined workflow.

HP E45C G5: One-minute review

Using the HP E45c G5, a 44.5-inch ultrawide monitor, is an experience. It’s not for everyone as the price tag is high, and it takes up a lot of space (as any 40-inch+ monitor would, of course). However, it’s engagingly immersive for media and, more importantly, allows for the ability to streamline a workflow where you need to look at multiple tabs or windows without having to switch between them.

If you’re looking for 4K resolution or need impeccable color accuracy and coverage for editing, your money may be better spent elsewhere. That’s not to say this screen isn’t great, or falls down badly in those respects, but the HP E45c G5 is among the best monitors for those looking for that immersive experience or ability to spread out a workflow, and not so much for other considerations.

Of course, if you’re reading this review, you’re probably looking for one of the best ultrawide monitors for your needs, anyway. In that regard, I think it’s up there.

HP E45C G5: Price and availability

  • How much does it cost? $1,099 / £959.99 / AU$2,045
  • When is it available? It’s out now
  • Where can you get it? Available in the US, UK and Australia

While the HP E45c G5’s price tag is certainly justifiable, $1,099 / £959.99 / AU$2,045 is not a small chunk of change to pay for a monitor. However, it fills a very specific niche as it’s for those who like to have the screen real-estate of two monitors, but in a somewhat more streamlined setup.

Looking at it from that perspective, the price tag isn’t so bad. Most decent monitors are going to set you back about $400 to $500 anyway, so getting two of them will be the same price as the HP E45c G5, while requiring two spots on an outlet or power strip for power, not to mention you won’t have a single ultrawide screen if you want to use it this way.

As for the similarly-sized competition, you’re looking at the same kind of asking price or more. For instance, the Corsair Xeneon Flex 45WQHD240 OLED is just as big and has a nicer OLED display with a faster 240Hz refresh rate, but costs $1,999.99 / £2,099.99 / AU$3,299.99.

Or, consider the Samsung Odyssey OLED G9 with its similar aspect ratio and resolution. Of course, it does have an OLED display as well, so it’s going to cost much more at $2,199.99 / £1,599 / AU$3,399. Really, the only way you’ll pay the same $1,000-ish price tag as this HP display is to find the older non-OLED version of this monitor or go smaller.

HP E45C G5: Design and features

When discussing the design of this HP monitor, we have to go into detail about the obvious fact that this thing is big. With a 44.5-inch VA panel, it’s made to replace the need for two monitors. In fact, I would say it’s mostly better than using two monitors as the 1500R curvature allows for a more natural way to take in the whole panel. Plus, you can either split the screen between two sources, or expand the screen real-estate of one source in a way that isn’t separated by the blemish of an inconvenient bezel (well, two bezels).

HP E45c G5 Specs

Screen size: 44.5-inches
Aspect ratio: 32:9
Resolution: 5,120 x 1,440
Brightness: 400 nits
Refresh rate: 165Hz
Response time: 3ms gtg (overdrive)
Viewing angle: 178/178
Contrast ratio: 3,000:1
Color coverage: 99% sRGB
Inputs: 1x DP 1.4, 1x HDMI 2.1, 2x USB-C, 4x USB-A, 1x RJ-45
Weight: 32.18lbs (14.6kg)

Of course, the downside with this one-panel solution is that you don’t have the same level of ergonomic control as with two separate monitors, so for example, some people like to use the second monitor in portrait mode, and obviously that’s not possible with the HP E45c. Aside from that, the HP monitor’s overall ergonomics are somewhat limited, offering a 10-degree swivel in either direction, along with a 5-degree downward tilt and 20-degree upward tilt. On a more positive note, at least its height adjustment is substantial at around 8-inches.

Another point in HP’s favor compared to using two monitors is that the HP E45c’s base, while substantial, takes up less space than you would need for two monitors. Additionally, its stand comes with some basic cable management to keep the desk looking tidy. On a side note, assembling the whole thing is much easier than I thought it would be – just attach the stand to the back of the monitor while in the box, attach the base, and just pick it up from behind.

There are plenty of ports available as well, including three video-capable inputs: HDMI, DisplayPort, and USB-C. While there are no duplicates, so you won’t be able to plug in two laptops that only have HDMI, that’s still enough to take advantage of its ability to split the screen between two sources. Also, that USB-C port can deliver up to 100W of power to one PC, or 65W to two computers.

There’s also an additional USB-C port and a couple of USB-As on hand for peripherals. Since this monitor is a multi-tasker’s dream, KVM is incorporated too. You can even plug in an Ethernet cable with the HP E45c G5.

The last design-related aspect I want to mention is the OSD menu button on the back. It’s situated all the way over on the right side behind the panel, requiring a bit of a stretch whenever you want to change a setting.

HP E45C G5: Performance

When it comes to performance, most of the negatives go right out of the window. Though this large display is limited to a (still great) 99% sRGB color coverage, its DCI-P3 coverage is not provided, and there are no settings for different color coverages, meaning that this is probably not an ideal monitor for photo and video editing.

However, for the rest of us non-creatives, it’s a blast to use. It still looks great with its dual QHD (5,120 x 1,440) resolution at a 165Hz refresh rate, and offers the kind of immersion for gaming and media that I found engrossing (I did have a powerful PC on hand to run it, of course).

This isn’t meant as a gaming monitor necessarily and is more targeted to worker bees who need a lot of screen real-estate to spread out on. This is an aspect I really appreciate, as I often have to look at several tabs to access and process different bits of information for articles and reviews. Additionally, the monitor can snap windows to an assortment of grids for easy organization.

HP was thoughtful enough to include a pair of 3W speakers. They’re loud enough and sound fine if you just need some audio in a pinch. But, if you care about sound quality, you’ll really want to pair this monitor with some decent speakers. This is true of 99% of the monitors I test, mind you, and it’s still nice to have integrated speakers as a little extra for a well-rounded experience.

Performance: 4.5 / 5

Should I buy the HP E45C G5?

Buy it if…

You hate switching windows or tabs
With this ultrawide panel, you no longer have to rifle through different tabs and windows to find what you’re looking for. You can streamline, organize, and spread out your workflow here.

You want an immersive experience
It might not be 4K, but the dual QHD screen is plenty sharp enough. And, with its 1500R curvature and ultrawide panel, you’ll be engrossed in whatever you’re doing.

You have multiple PCs to connect
As a monitor meant for multi-taskers, the HP E45c comes with the right kind of features including KVM and picture-by-picture so you can seamlessly switch between two different computers.

Don’t buy it if…

You’re on a budget
Compared to buying two separate monitors, the price is right. But if you’re on a budget, you can get a decent monitor for much less. You’ll just need to go smaller.

You need portrait mode
If you’re considering alternatives to a second display, just be aware that by the very nature of this monitor, ergonomically speaking you’ll be forever locked in landscape mode.

Also consider


Corsair Xeneon Flex 45WQHD240 OLED
It’s much more expensive, but this monitor from Corsair has one advantage – you can bend it to adjust for different situations, as you might not always want that much of a curve. It also comes with HDR, though the ergonomics are just as limited.

Samsung Odyssey OLED G9
If you prefer a 4K resolution, this ultrawide monitor has it along with the deep contrast levels we’ve come to expect from OLED-equipped displays. Of course, the port variety could be better and it is more expensive.
