I've rounded up the final Prime Day portable monitor deals you can still get right now

You won't be at a loss to find portable monitor deals in this year's Prime Day - Amazon tends to be swamped with them. But here are a few things to look out for when selecting which one is right for you.

Screen size

The vast majority of portable monitor displays tend to be 15.6in, which is the same as your standard laptop. However, I do see 14in and 18in models discounted in the sales (and everything in between). For maximum portability, I quite like these 14in models. Anything smaller than this tends to be targeted towards Raspberry Pi users, and while good on the go, a larger-sized tablet may be more practical.

Size and weight

It's not just screen size you'll want to check. Other dimensions to take into account is the thickness and the weight - ultra-thin portable monitors are billed around 0.2mm, weighing in at under 2lbs / 1.7kg.

Resolution

Most portable monitors in the Prime Day deals will be 1080p (or FHD). And for smaller screens, that's absolutely fine. While I wouldn't say it's essential to get more than that, you can opt for 2K or 4K if you want the extra detail, although you won't see the benefit in the same way as you would with a full-sized 4K monitor or TV screen.

Brightness

Like any monitor, portable screens come with different brightness levels, typically measured in nits. If you plan to use your display outside, I'd opt for something with at least 500 nits. Inside, you can probably get away with 250 - 300 nits as the absolute minimum, but I'd still try to get as high as you can here.

Connectivity

In the main, portable monitors carry at least one USB-C port, which can also be used for charging those without a built-in battery, but a lot of them seem to have two of these, alongside a mini HDMI. That's useful for connecting a variety of different devices.

Battery

On the point above, it's worth seeing if your chosen display has a battery built in or can be plugged into the mains. I don't see many with these, as they pull charge from the connected device, but larger screens may have these, and they let you use them more readily on the go. Most cheap displays won't have this option.

Color gamut

While not an essential, if you plan to use your portable monitor for the likes of photo editing or other content creation, make sure to check the color gamut. I see a lot of displays hitting 100% sRGB, but DCI-P3 will be even better for professional usage.

Kickstand

To me, a kickstand is absolutely essential, and they tend to come in two varieties: a pull-out stand attached to the device (like the Nintendo Switch 2) or a cover that can prop up the monitor like a kickstand. Some screens also have brackets, like a more traditional monitor stand, or are VESA mountable. Avoid any portable monitor that no option to stand it up.

Brand

Amazon is absolutely packed with different brands, but I'd look out for the likes of Arzopa, UPerfect, InnoView, Elecrow, and Intehill, as well as more established brands like Asus and Lenovo. That's not to say cheaper brands aren't worth checking out, and you'll find some of them in this round-up, but I'd check reviews to see what other users think before commiting.
