VX1655-4K-OLED 16 Inch 4K UHD OLED Portable Monitor for Laptop

I bought this portable monitor to add a second screen without carrying a full-size display. Setup was straightforward: I connected it over USB-C and the picture appeared quickly, with no separate software needed for my setup. The 16-inch 4K OLED panel is the highlight. Text looks sharp, colors are rich, and the screen is easy to use for documents, coding, and photo viewing. It is thin enough to slip into my bag, and switching between my laptop and another input is convenient. My main complaint is that the built-in stand and cable arrangement take a little fiddling to get positioned exactly where I want them. It also makes sense to carry the right USB-C or HDMI cable rather than assume every laptop connection will work the same way. Overall, this is a practical, high-quality second screen that I have enjoyed using.

At my home office I have three Dell 27 inch 4K displays, connected to my 16" M4 Max MacBook Pro. When I'm traveling going down to a single display is quite an adjustment and definitely impedes productivity. I've tried portable add-on monitors in the past and have even traveled with a spare 27" desktop monitor, but until this 4K OLED screen from ViewSonic, I've never found something that was portable, convenient, and had good image quality. This screen is wonderful. I just need it and a USB C cable and I have dual screen productivity. It works so well that I almost bought a second one to replicate my three screen setup at home. Everything about it is perfect except these small complaints: 1) I wish the brightness could automatically match the MacBook Pro display. Setting the brightness on this screen requires a few button presses and toggles on the single button on the back of the screen. It would be great it if just automatically synced with the brightness of the laptop display. 2) The speakers are wasted space and weight. They shouldn't include speakers in a screen like this. They are pointless in 98% of use cases. 100% for me, since I'm only going to use this screen with a laptop or maybe iPad, both of which have their own speakers. 3) I wish the aspect ratio / screen shape matched the 16" MacBook Pro. When you move windows from one screen to the other, you have to waste time resizing them for the different shapes. Other than these three very small complaints, this screen is perfect. I really like it and recommend it.

Bought this for working on the road. The display is AWESOME but the features are bare bones for such an incredibly nice 4KUHD OLED display. Be forewarned that this device requires an external 20w power source and comes with a gigantic and cheaply made power block. My Anker A2669 was able to drive it with ease though so it will just go into the bin with all the other spare chargers. Annoying that there's not a low power mode to drive directly over USB-C from a device without external power. Flipside though is that if you're driving data to the display with USB-C that it will charge the device (such as a laptop). The speakers are awful and don't support external volume control. Like free airplane earbuds level bad. There's an annoyingly large VIEWSONIC logo on the bottom of the display that cannot be removed as it is under the glass.. I'd have paid $100 more just to not have this on there. It'd be nice to have AirPlay/Chromecast built-in to easily display from a mobile device. A common scenario when presenting to clients on the road. I still have an iPhone 13 Pro Max but couldn't drive the display (lightning to USB bandwidth limitation suspected). Unclear whether a true USB Apple Device can connect directly. A specific quality/type of USB-C cable is required. The cables included work fine but my nice vinyl wrapped Anker cables did not. All in all a very high end display with no bells or whistles. The type of consumer who will buy this product expects those and certainly would pay extra for. Hopefully someone within ViewSonic product management sees this and releases a "Pro" model.

I've purchased 4 of these (OLED version) to hang off of a GPU enclosure connected to my laptop and they are the best screens i can find and have them right next to my Apple Studio display with the same quality. The 4K resolution and the size are a perfect match for a full workplace on one screen. I cannot explain how much more efficient my workflow has been with these screens!

Compact and very vivid portable monitor. I love it as it does not have a built in battery to go bad over time, rather it pulls power from the computer. While this does drain the laptop battery faster, it is worth the trade off in my opinion. Very Vivid 4K screen. and bright! Highly recommended as a second monitor for those on the go. It is a bit pricey compared to other brands, but having the name that is trusted and quality to match, is worth the extra price.

I had issues with the monitor on a MacBook where the display would randomly disconnect and reconnect, sometimes in a loop which required me to unplug it from the laptop and plug it back in using USB c. I replaced the shipped cable with a higher end cable and no difference. I tried to adjust refresh rate between 60, 50 and even down to 30 which makes the monitor pointless imho. As a last resort I tried a USB c to mini HDMI cable. It was even worse - it would never do more than endlessly disconnect and reconnect. After that I tried using USB c again and basically it has not worked since at all. This now beyond the return period. I will never use a ViewSonic panel again - I was basically ripped off for $499 and will now need to purchase another from some other brand because this is absurd.

Good quality but connectivity is not good. Have to reconnect after sleep mode

First of all, I don't usually write reviews. But I'm hoping to help the other professionals out there who NEED PORTABLE 4K!! I've purchased at least 5 of these now, 3-4 no name versions and even a couple from ASUS. But all have similar problems - work on one computer, not another - Complex install processes with drivers that don't work well - Dim picture unless supplied with external power. This one does exactly what you want. USB-C connection, immediate recognition (windows 10 at least) and menus that work about as you would expect. The OLED display looks like you think it should. Bright and very colorful. 4K at this size is a little ridiculous and not for everyone, but I use a couple applications that need 4K for scaling and zooming purposes. This is perfect. I haven't tried to connect it to mobile devices like phones and tablets yet, but it's supposed to do that too. I also haven't tried the reverse power method where you plug in the screen to the wall and then power the laptop off of that, but it is a nice feature. Just had to share.

Like: * So light, so thin, well built, nice finish. * Very colorful panel ( best in fps2 color mode for me). * Oled 4k panel, true black * Display as good color quality as viewsonic VP16-OLED. * Single cable Type-C to handle both monitor power and AV. * Integrated speakers (loud enough) + headphone jack included. * Comfortable for portable office work * Text does looks clear and white. * Overscan mode on-off * Rgb range limited/full setting toggle * Retro gaming looks fantastic, as modern gaming. * 10-bits colors when using type-C as video source under win11 * Included integrated power supply with detachable cable Dislikes ( all i said below have minimal impact on the overall quality of this monitor) * It's not used to display HDR content even if it will work. It doesn't look good when HDR on. * Limited to 60hz * 15.6" still feel a bit small, still it's ok to be used as a main monitor. * Can't use the built-in stand to display the monitor vertically (as oppose to another viewsonic oled , the vp16-oled) * Even when using office mode, It's by default too bright. At nighttime, would be nice to a color mode which have very low brightness by default * It's not a big deal but Hdmi as output renders 8-bits colors as oppose to Type-C 10-bits (under windows and problaby in general). * Can't be mount on a tripod or stand. You need VP16-OLED for that. Very happy to own it. Compared with VP16-OLED, they both display similar results , 4k movies looks the same on both, color wise can't tell difference. Office work is much better on this monitor compared with VP16. Perfect for backpack , very light you won't notice it at all.

薄くて軽いのが良い そして、目が疲れない ちょっと高いけど買ってよかった

Si esta súper ligero, y la resolución no decepciona.

Insanely gorgeous OLED picture quality. I have a MSI URX-321 monitor and the picture in this little guy is every bit as good or even better. The speakers are good enough for basic tasks, anything more than browsing the internet I would strongly suggest external speakers. The screen cover is nice, be careful not to forget it in the box, it could easily be missed and tossed. Rubber nubs on the bottom of the screen and stand keep it in place very well. The control knob is intuitive unlike other manufacturers. The back stand is functional though I’m not sure how much abuse it would take. Pricy at double the price of similar IPS panels, more than double in the picture quality on this OLED example, I would strongly recommend as the best option.

I am blown away by how nice this portable monitor is. It is glossy and the colours are deeper and more vibrant than my 34in OLED. I love how sleek and thin the profile is and the fact that the USB C slot isn’t in the side of the monitor but on the kickstand allows me to hide cables and have it look clean permanently as a second screen (I know I didn’t hide the cables in the picture yet but I was too excited to post this review). Worth every penny.
