ViewSonic VX1655-4K-OLED 16" Black 2023

The ViewSonic VX1655-4K-OLED is a 15.6-inch 4K OLED portable monitor that delivers stunning picture quality and colors in a super light, travel-friendly package. Buyers rave about the panel, build quality, and MacBook compatibility, though some report USB-C quirks and wish for a higher refresh rate. It's expensive compared to IPS portables, but for frequent travelers who want the best image quality on the go, it's a standout pick.

Let's talk about what this panel actually delivers. The OLED is the star here. Colors land at 100% DCI-P3 and the panel pushes 400 nits, which in our database puts its display quality on par with the best portable monitors available right now. Black levels are the kind of inky, gaping void you only get from OLED, not the grayish smear you get from even good IPS panels. For photo editing or watching content on the road, this screen is a genuine step up.

Portability performance is where this thing truly stands out. At 680 grams with a foldable cover stand, it's built for travel. The display ranking in our database is top of the charts for this category, and the color performance isn't far behind. The 4K resolution at 15.6 inches means text is ridiculously sharp, so reading documents or editing spreadsheets on a second screen doesn't feel like a downgrade from your main display.

Now the less fun stuff. The refresh rate tops out at 60Hz. For office work, photo editing, and video, that's entirely fine. But if you were hoping to drag this thing into a gaming setup, you'll feel the cap. The 1ms response time is a nice spec on paper, but without a higher refresh rate it mostly helps with ghosting rather than giving you a competitive edge. HDR support exists but owners consistently report it's underwhelming, so treat this as an SDR monitor with great contrast rather than an HDR showcase.

Stacked against the competition, the VX1655-4K-OLED is in a weird spot because most of its notable rivals are desktop-sized OLED gaming monitors. The ASUS ROG Strix XG27UCDMG and MSI MAG 271QPX QD-OLED both deliver higher refresh rates and bigger panels, but they're desk fixtures, not something you toss in a bag. The LG UltraGear 27GX790A-B and Samsung Odyssey G60SD are similarly sized and similarly stationary. If you need portability, none of those are actually competitors. If you don't, all of them beat the ViewSonic on gaming performance and HDR.

Where the ViewSonic wins is the specific niche it occupies: a 4K OLED screen under 700 grams that fits next to a laptop in a backpack. No mainstream competitor we track currently matches that combination. The Gigabyte M Series OLED MO27U2 SA comes closest in spirit as a content creation OLED, but at 27 inches and desktop weight, it's serving a totally different use case. For someone who wants a second high-end screen on an airplane tray table, the ViewSonic is closer to having the field to itself, which is part of why it can command that price.

Value is the sore spot here. Portable 4K IPS monitors with similar sizing often sell for meaningfully less, and you're paying a premium for that OLED panel. Across US listings we tracked, the price lands between USD 450 and USD 505, which is a spread worth shopping around. Newegg had the lowest price in our data, while the Amazon listings sat higher. In Canada the gap is even wider, running from CAD 625 up to CAD 737. If you're north of the border, Newegg's CAD 625 price is the one to chase. For that money you could buy two solid IPS portables and still have change left over, but neither of them would give you true blacks or this level of color accuracy on the go. Whether that's worth it depends on how much you value image quality in a second screen.

The ViewSonic VX1655-4K-OLED is a 15.6-inch portable monitor that packs a 4K OLED panel into a 680-gram package. That combination puts it in a price bracket where you're really paying for the panel tech and portability, not extra features. If you've ever squinted at a dull, washed-out portable screen in a hotel room or coffee shop, this is aimed directly at you.

Buyers searching for a portable OLED monitor usually ask two things: is it bright enough to use near a window, and will my laptop actually drive it over one cable? The 400-nit brightness and 100% DCI-P3 coverage handle the first question pretty well. The second one is mostly a yes, though not universally, which we'll get into below.

Spec-wise you're looking at 3840 x 2160 resolution at 60Hz with a 1ms response time. It runs on either USB-C or Mini-HDMI, and the built-in kickstand supports both landscape and portrait orientations. There's a pair of small speakers and a headphone jack if you need audio, but set expectations low on those speakers.

Skip this if you're buying a second monitor just to have extra screen space and don't care about panel tech. A cheaper 1080p or 1440p IPS portable will handle email, chat, and document work for a fraction of the price. Gamers should also look elsewhere, since the fixed 60Hz refresh rate and weak HDR make the OLED panel feel wasted for fast-paced play. And if you're on a tight budget and weighing this against a quality desktop monitor, you'll get more inches and more features for the same money by sacrificing portability altogether.

Should you buy the ViewSonic VX1655-4K-OLED? If you're a frequent traveler, a remote worker who bounces between locations, or a photographer wanting a color-accurate reference screen in a compact size, this is one of the best options we've seen. Owners consistently praise the build quality and the way text renders on macOS, which matters way more than spec sheets suggest when you're staring at spreadsheets for hours. The portability score in our database is basically off the charts, and display quality isn't far behind.

But if you're a gamer looking for a portable battlestation, or you just want a cheap second monitor for occasional use, this probably isn't your best use of money. The 60Hz ceiling and weak HDR mean a cheaper high-refresh IPS portable might actually serve you better. This is a monitor for people who care about image quality first and everything else second. If that's you, it's an easy recommendation despite the price.
