Acer PD3 Dual-Screen Portable Monitor: Two-minute review

While we already have a round up of the best portable monitors you can find, Acer aims to shake up the rankings with its Acer PD3 Dual-Screen Portable Monitor. This device, similar in fashion to other portable monitors, is small, lightweight and can be folded up to be taken with you on the go.

However what sets the Acer PD3 Dual-Screen Portable Monitor apart is the fact that it has two connected monitors, as the name suggests, for those who need the extra screen space.

One of the first things I noticed when unboxing the Acer PD3 Dual-Screen Portable Monitor is that the device is actually quite heavy, weighing in at over double that of my MacBook Air. Coming in at 2.33kg (5.14 lbs), it definitely isn’t too heavy to take on the go, but it’s by no means the lightest thing in your backpack and very well may make your bag quite hefty when combined with your current laptop.

The Acer PD3 Dual-Screen can be opened up like a laptop and used either horizontally or vertically. Initially I was worried the stand would be quite flimsy, but it's stable and holds up the device perfectly fine. In terms of design, the Acer PD3 dual-screen is very sleek and simple. Contained in a black, metal chassis, the device is simple and blends in seamlessly with any set up.

At 2.45cm (0.96in) thick, the device is quite chunky when compared to other laptops and portable monitors on the market. However, it’s worth noting that it's not this thick all the way around, with a large chunk of the monitor being quite thin, which makes it feel somewhat slimmer than it is.

The ports on the monitor are actually located underneath the stand, meaning the stand has to be pulled out in order to access them. While this isn’t the biggest deal in the world, it’s somewhat frustrating at times as you don’t always need to have the stand pulled out to have the monitor stood up.

Despite being an LCD panel, the Acer PD3 Dual-Screen Portable Monitor looks absolutely fantastic with a great range of colors and blacks. However one downside is the 250 nits screen, which isn’t the brightest, particularly when using the device on the go in different lighting environments. My laptop, which I used in conjunction with this monitor, has a screen brightness of 500 nits which makes the monitor appear even less bright in comparison.

With each screen coming in at 1920 x 1080p, it seems perfect as I didn’t have to worry about screen sizes and ratios changing when plugging my laptop in - which has the same resolution screen.

When using the Acer PD3 Dual-Screen Portable Monitor, it sufficed perfectly fine. It was easy to use, essentially just being plug and play with it syncing up to my laptop practically instantly.

It’s worth noting that the device can be VESA mounted - and while I didn’t mount it myself since I used it mainly on the go, it’s interesting that you can add it to a single monitor arm for a dual screened display, saving you even more space on your desk if needed.

It was easy enough to chuck the Acer PD3 Dual-Screen Portable Monitor in my bag and use it in different locations but I will say it wasn’t something I was comfortable pulling out while on a long train journey or in a coffee shop. The device itself is pretty large and looks quite elaborate so I didn’t find myself using it often when away from a desk. It was fine enough to take to my workspace, where it’s normal to use multiple screens.

However, considering the Acer PD3 Dual-Screen requires its own power outlet to work, it's not something which would be very easy to use on the go anyway. It comes with its own 45W power adaptor which plugs into the device via USB-C. This was frustrating as it meant I also needed to ensure I had the power supply with me when taking the device, which adds even more weight to my bag.

Acer PD3 Dual-Screen Portable Monitor: Price and availability

• How much does it cost? $449.99 / £469.99
• When is it available? Available now
• Where can you get it? Available in the US and UK

While quite pricey, the Acer PD3 Dual-Screen Portable Monitor is definitely a more premium option when it comes to these devices. At just under $450 (£469.99), it’s much more expensive than alternative portable monitor options like the AOC 16T3EA portable monitor which costs $129 / £187. However, the AOC 16T3EA is a single screened monitor, whereas the Acer PD3 is dual-screened.

Alternative dual-screen options like the Uperfect Portable Monitor come in at a similar price point to the Acer PD3, at around $449.99 / £449.99. This places the Acer PD3 Dual-Screen Portable Monitor an average priced option for the functionality, but it’s currently hard to judge as there aren’t many alternatives on the market just yet.

How I tested the Acer PD3 dual-screen monitor

I spent a few weeks using the Acer PD3 dual-screen monitor alongside my laptop as a secondary display. I attempted to use the device on the go and take it to different locations with me.

I primarily used the device for working and productivity purposes like editing photos, responding to emails and writing articles. I also used the monitor to watch videos and movies to see how well it displayed different colours.

I’ve tested a range of different displays, monitors and portable devices over the years.

First reviewed April 2025

We were hoping to review the AOC 27B3CF2 in this Labs, as you can buy it for a similar price to the 27B3CA2 and they’re identical but for one factor: the stand. Where the version with A2 at the end has a lightweight plastic stand that keeps the monitor at a fixed position, with the bottom roughly 110mm above your desk, the F2 offers 110mm of height adjustment.

Both monitors offer the tantalizing prospect of a 27in USB-C docking monitor for around £150, and to hit that price point AOC has had to make some compromises. Let’s start with the features: you only get two USB-A ports (5Gbits/sec), and nothing in the way of extras, unless you count the 3.5mm headphone socket. Aside from this, only an HDMI port graces the rear.

Nor do you get hedonistic features such as a stand with swiveling capabilities, but as this unit weighs a mere 4.4kg it’s easy to maneuver and to carry round an office. At least you get some tilting action, with 5° forward and 23° back.

Naturally, this is a Full HD monitor rather than 1440p. As with all its Full HD 27in rivals, you lose sharpness around text edges, and there simply isn’t as much room for details, which makes it less useful for workers who like to view two documents side by side, especially if one of those documents is a detail-packed spreadsheet. However, whites look fine, so we were happy to use it for day-to-day tasks, and with 65W power delivery over USB-C it could be rolled out in offices where workers bring in their own laptops.

You shouldn’t expect bags of color; next to the Acer Vero B277 Ebmiprzxv, there’s only one winner. It covers a reasonable 92% of the sRGB gamut, though, and an average Delta E of 1.35 suggests respectable color accuracy. The one area of our testing where it fell down was brightness and contrast uniformity: out of 24 test areas, DisplayCal only gave one the green light.

We would love to end on a complimentary word about speaker or OSD quality, but sadly, no. In “Englishmen in New York”, Sting sounds like he’s singing down a phone line from the 1970s, and AOC’s OSD is looking increasingly dated compared to rivals. It’s okay once you get used to it, but there’s an unnecessary learning curve.

All of which means that there really is only one reason to buy this screen: that you’re desperate for USB-C docking and only have £150 to spend. In which case we recommend you seek out its 27B3CF2 sibling with an adjustable height stand.
