The UPERFECT UColor O2 is a brilliant portable monitor

After recently having the chance to review the rather large UPERFECT UMax 24, the team at UPERFECT sent over the much more portable 16 inch UColor O2 for me to take a look over.

In terms of portable monitors, if you're after something that's easy to carry around, this is an excellent feature-filled all-rounder. To ensure that I gave it a thorough look, I've been using it constantly over the last month and I've really come away impressed by the durability of it as well as how gorgeous it is overall.

Compared with the UMax 24, the one quality-control issue I had with the UMax were the wobbly side buttons for interacting with the on-screen controls and swapping inputs. Thankfully, the UColor O2 doesn't have this issue, the buttons feel nice and solid.

Arriving with everything you need out of the box to get you going you'll get the monitor, a kick-stand cover, 2 x USB-C to USB-C Cable, 1 x Mini HDMI to HDMI Cable, a power adapter and screws for mounting. It's has VESA-compliant holes all ready if you decide to mount it somewhere.

Everything worked as expected, and using my Steam Deck LCD once again as the testbed for it, there hasn't been a single issue. Absolutely perfect, and games look fantastic on it. The image quality is great, remaining exceptionally clear at various angles.

With the on-screen display there's a blue light filtering option which goes across 4 levels, so if you need to tone it down to save your eyes you can. You also get access to change the brightness, contrast, eco mode, DCR and sharpness. On top of that you can change black levels, hue, saturation and colour temperatures to get it exactly where you want it for maximum comfort.

Considering how thin it is, and how much I travel between locations a fair bit nowadays (along with multiple small people running around), the durability and feel of it has impressed me. And uh — sorry UPERFECT, that includes it being fully dropped 5 or 6 times (probably more…) without it causing a problem. It's truly a rock solid device. I'm not going to suggest you go throwing it around, but it's good to see a portable actually be portable between locations, moving around bags and being dropped.

I am especially a big fan of the magnetic cover it comes with, which doubles up as a stand making it easy to set it up wherever you go. All together, this is now my go-to whenever I'm moving around because it's just so easy to slot into a bag and off you go while being fully featured.

Really light too, making it super-simple to carry around single-handed without a fuss.

Even when I'm at home and not travelling about, the UColor O2 has made break-time even better at my desk just quickly flicking it on and picking up a gamepad. As much as I love the Steam Deck, and I love getting away from my desk with it, I've actually found myself playing a lot more at my desk with it since I can get a bigger quality screen, with a lighter gamepad in hand while also keeping an eye on the unrelenting barrage of emails that have been coming in lately.

A little gripe with it is the same as the UMax, I just wish the speakers were that little bit louder, but still good enough for a portable monitor. Additionally, the on-screen UI for adjusting settings is annoyingly fiddly to work with, as is the case of basically every monitor ever. I saw my face in screen way too often after accidentally turning it off. Once you get used to the buttons though it makes sense with certain buttons mapped for quick-access to brightness, volume and video input with another button going into the full menu of all the options.

If you absolutely require a device that has a built-in battery though, you'll want to look elsewhere, as it does need to be directly powered. However, they do actually have another model (not tested) that has a built-in battery that's worth a look available at the same store link below as the O model (the O2 is what's tested here).

Thank you to UPERFECT for their trust in sending it over.

Check it out on their store. Priced normally it's £474.19 but they currently have it listed on sale for £263.44.

It's good to see more 16:10 displays. It's a funny resolution, though; I wonder why they didn't go for 2560×1600? That would have been a handy 4:1 integer scaling from the Deck's own display.

I'm not seeing the value here. Even on sale, that's more than I paid for my Asus 27-inch QHD monitor. I know OLED has some small advantages over QHD, but it's not enough to justify the price difference.

Because this is portable and not 27 inches? You can fit this is your bag.

So you're paying more for less.

You are paying for the convenience in having a portable monitor that fits in a bag. Probably worth it for people in the market for this.

So two USB-C. One for power, one for input. I have looked at the product site and I'm unable to figure out if the latter can provide power to the Steam Deck (or PD-capable laptop). Am I missing something or is unclear from the info available?

If not and I occasionally have to unplug everything to get power to the Deck (or use some weird dongle arrangement) it looses a lot of it's appeal.

There's this:
One type-c cable can realize various USB C equipment connection, can transmit signal and charge at the same time.
So, you can charge devices from the usb-c port, but I can't find any power output specs even in the manual. Should be enough for a mobile device, possibly the deck, but I don't know if it can provide enough power for a laptop.
