VX1655-4K-OLED 15.6 Inch 4K Portable Monitor, OLED Display for Immersive Mobile Workspaces and Second Screen Productivity, Built-in Stand, 60W USB-C, and Mini HDMI Inputs

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.

Very, very happy with this screen I got it to go with my Macbook Pro M5 and its gorgeous screen It is just AWESOME. Looks gorgeous and has excellent quality for text and movies BOTH Hooks up easily. Has a little pull out stand I use at coffee shops etc for dual screen action I really could not be happier. Just perfect as far as I am concerned. The only complaints I would have would be nit picks and not worth posting Hooks up to the Macbook Pro instantly upon connection and not even an issue occured Just set which display I wanted it to be and was ready to go After than it takes 5 seconds to connect and turn on when I use it I am very happy!

I’ve been using this monitor for nearly a year now so I figure I’ve had enough time with it to leave a genuine review. For starters I think the quality of the display is great. I have become spoiled by OLED displays so after using something like this, I’m not sure it’s possible to go back. The picture looks great when watching movies and while playing games. I’ve used it with my Nintendo Switch, PS5, and as a display for my Mac. One of the things about macOS is that the interface is really designed around Apple retina displays with high PPI (pixels per inch). A display like this works great and provides sharp text (rendering at a logical resolution of 1920x1080 @ 2x). The other main benefit of this display is the size and portability. It’s very light, and the magnetic screen cover provides protection against scratches which makes it really easy to travel with. It can fit in a standard backpack no problem. It’s also small enough that it can be used with some iPad/tablet mounts that stretch around the monitor on the top and bottom. It can be used flat on a desk as well since it has its own built in stand. It’s nice that you can power a computer from the display so you don’t need two separate power bricks. Give the full power to the display then plug your laptop into the other USB C port using a USB C cable with enough bandwidth to handle 4K. The display offers a lot of color and display options to fine-tune the picture, but I find that it works pretty well right out of the box so I haven’t gone crazy with the settings. I have tried HDR though which looks very nice. One downside there is that you can’t adjust the brightness when using HDR, but I think that is pretty common. I also appreciate the built in blue light filter for using the display late at night. I generally prefer to handle this on the software side, but it’s nice to have the option here. Now for the downsides/areas for improvement and why I rated it 4 stars and not 5: - The power brick that comes with the display is quite large. This seems counterintuitive considering how portable the monitor is otherwise. I use a small 65 watt Anker brick for powering it. It’s nice to at least have this option since it’s powered via USB-C - The ports feel kind of delicate. I understand why you might use mini HDMI vs. a full size HDMI port, but every time I plug it in and remove it, it makes me kind of nervous that the pins may get damaged since the connection doesn’t always feel right even with the provided cable. - The sound quality is pretty terrible. It’s better than having no audio at all, but it’s really not great for using on its own. It has a 3.5mm audio port that you can use to plug in headphones or speakers so that’s useful, but it is annoying to have to even think about that. Also the port is somewhat difficult to access just by feel and hard to plug and remove cables from since it sits so close to the mini HDMI port. - While the display looks great for most content, there is vertical banding that you can see when the screen is displaying certain shades of gray, particularly noticeable in low light environments with the brightness turned down (see attached video). I originally thought this was a defect, and actually went through a whole swap with ViewSonic, but the new monitor they sent me had the same issue so I sent it back. Their customer support was great though through the entire process. Vertical banding is actually fairly common with OLED displays, but some have ways to calibrate or improve it via the firmware. - The menu/interface for adjusting the settings on the display is fairly confusing. It uses a joystick on the back of the monitor which also functions as a button. This means since there is no way to go back you have to use the joystick to navigate in and out of menus via an on screen guide. It’s usable, it just takes longer than I would like. Particularly, I wish there were standalone controls (up and down) for brightness and audio volume. Currently, if you want to change the brightness you have to press in on the joystick, navigate to the right submenu, press in, scroll down to brightness, press in, move the joystick to the left or right, press in again, then navigate out to exit. It takes way longer than having a standalone control.

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 use this screen with a 2022 16" MacBook Pro and with a 2023 Lenovo Thinkpad X1 (OLED). It is the perfect companion for both. The build quality of the screen is excellent, and I was pleasantly surprised at how light it is. It worked flawlessly with both laptops. Plug and play. Image quality is outstanding which was important to me given the screens on both of my laptops have high resolution and brightness. This has been an issue with other screens. I work remotely across several sites and it is important to me to have dual screen capability. I have tried a few different screens - this is by far the best. It is also great for consuming content. The only issue I have noticed is that it has a different colour temperature to the screen on the MacBook Pro (it is bluer). It matches the Lenovo exactly. I don't think this is a problem - it is just different. Would love to see a touchscreen version.

Upon testing the monitor, I found that the resolution and color quality are not as expected for an OLED 4K display. The colors appear dull, and the resolution does not meet the sharpness and vibrancy typically associated with OLED 4K screens.

This is actually my first time writing a review on Amazon. I was so excited to finally have what I was looking for! So I hope to help out anyone thats struggling. Portable monitors seems to be a growing trend so not much precise information online. It took me some trial and error with different brands, both well known and third party but this one is it. Overall this monitor fits in everything that I was looking for in a portable monitor. Now to begin with my specific use case; I am a professional photographer, and at the moment a Computer Science student. I wanted a portable monitor that fits in all of my bags along with my laptop, allows me to do some photo and video editing (16" MacBook Pro), would connect to my cell phone via USB-C (iPhone 15 Pro), would allow portrait mode for coding projects, and would plug into Nintendo Switch without needing a dock. This is the one that delivered! So thank you so much ViewSonic for delivering! Some caveats to mention, One Cable USB-C works prefect with the MacBook Pro, even in 4K resolution. To use with Nintendo Switch or iPhone, the other USB-C port has to be connected to a power source. Wall outlet or PowerBank. (In my scenario I used and Anker PowerBank and it works!) This is will all portable monitors though, not just this one. So here's why I settled with this one. Pros: + Super lightweight! This screen is approximately 1.6lbs and will add nothing in weight for carrying. + Very Portable! 16" is a great size and it does a good job at being close to matching the MacBook Pro. + 16" OLED 4K screen (Its great to watch movies but don't expect it to replace a 65" 4K OLED TV). + 170 Degrees Visual from different angles (Consistent image quality from different angles). + 100% DCI-P3 coverage/most of Adobe RGB (which is great for color accuracy, photo and video editing) + Built in Portrait mode which is great for coding or editing (might need to level the stand) + Has a built in speaker (No, they are not strong but at least its provided, better than nothing) + 3.5mm Jack (plugs into a portable speakers with 3.5mm Jack or headphones) + Provides Power to devices (iPhone 15/Switch) that are connected via Wall Outlet or PowerBank. Cons: - 60hz only (would have been even better at 120hz to match my Mac, and maybe the Switch 2?) Probably asking for too much but would hav been the icing on the cake. - Expensive ~$500 (but to be honest it's not really a con, you get what you pay for and for it to do everything that I need without extra dongles. I'm perfectly fine with paying the price tag) Overall though I can't complain about this purchase; just being a little nitpicky. If ViewSonic decides to keep producing these and release a version with 120hz, I would buy it in a heartbeat but as of now it's perfect! Check out the attached photos for my use cases. -----| The only other well know brand I tried was the ASUS ZenScreen MB16QHG. Almost kept it too but I did not want to carry around with me additional dongles for my Switch: Pros: + 2K + 120hz + Built in Stand (Portrait mode too) + 3.5mm Jack + 100% DCI-P3 + Full HDMI Cable (Not Mini) + Great Portrait Mode Stand + Auto-Rotate (Windows Only) + Very Lightweight Cons: - It doest NOT connect the Nintendo Switch without a dock, then even with a dock connected the 16:10 aspect ratio doesn't not convert to 16:9 for gaming. It left the gameplay looking distorted and for me personally I wasn't a fan. - No built in speakers - Expensive while lacking features ~$400 -----| The only third party brand I tried was the UPERFECT 18" Gaming Monitor (Almost perfect). Would have kept it if I was just for gaming. But it doesn't fit all my bags, and having to constantly recalibrate it would have sucked. Pros: + 2K + 144hz + Connects to Nintendo Switch via USB-C without a dock + FreeSync + Both 16:9/16:10 + 100% DCI-P3 + Vesa Mount + Affordable ~$257 Cons: - 18" Screen not very portable. - Passible Portrait mode needs Vesa Mount Stand to be more stable. - Brightness settings reset when disconnected from power.

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.

Light too, what's more to love?

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.

Great monitor that I use for travelling and as a second monitor on my desktop! Vibrant colours, and nice and thin!

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.
