INNOCN 15.6 inch Portable Monitor Touchscreen 4K OLED PU15-Pre USB Type C HDMI External Monitor with Battery for Laptop PC Mac Tablet PS4 Xbox Switch

Fantastic product for the price. When I bought it it was on a %40 discount which made it a no brainer. I didn't technically need a portable monitor, but I bought this as an OLED "trial". You've probably seen those 27" LG QHD 240hz screens already but those are $1000 (insane price gouging), but you as a consumer have likely never had an OLED monitor, so the question remains: will you burn-in that super nice and expensive screen? I wasn't willing to experiment with my money. At $150, this INNOCN is the perfect test: I use it for gaming at %100 brightness and it will blow you away with the quality of the colors and contrast. Looks great during the day, and mind-blowing at night (actually TOO bright for me though, so at night I set it at %47 brightness). The rest of the workday, I have it display my week calendar at %10 brightness - OLED blacks guarantee that there's still plenty of contrast to remain easily readable, and this way I can test if I'd burn-in an OLED monitor after months of use. If it burns? Ah well, $150 isn't an excessive loss. If it doesn't burn? Then I can buy the nice 27" QHD OLED versions that are starting to come up (I don't want/need a 34 inch or a 45 inch ridiculousness).A couple interesting things I've noticed:- %20 brightness on USB-C video is fine at night. During the day, it's not enough, plug in the USB-C power cable as well (and this comes from someone who does not enjoy bright screens, my eyes are sensitive).- INNOCN does something weird with near-blacks in dark images as you change brightness. I noticed that at %47 brightness all detail is retained in a near-black situation, but if you go to %48 instead of making the whole image brighter, it makes near-blacks darker, thus crushing them... it's strange. There seem to be a few "brightness zones" within which the screen manages contrast as you go up in brightness, so I've found 3 perfect levels for my use: %10 induces black crush, but I only use it for a black background calendar, so it's fine (this is my test to see whether the white text at %10 would burn-in after months of use). %37 preserves near-blacks and adds a good a mount of brightness. %47 is as high as you can go preserving near-blacks while increasing brightness. Any higher than that, and blacks get increasingly crushed until about %70 (weird mixture of crushed-blacks but brighter image). After %70 blacks start raising again (along with overall brightness) but it's not a "%47 brightness equivalent but brighter" until you hit %90 to %100. So, I recommend setting the first 3 of 6 "modes" (which seem to do nothing other than change brightness, as I've set them all at %47 and they look virtually the same) at something like %10, %37, %47 for different lighting conditions, and the last three modes at %100 since anything between %48 and %99 messes with near-blacks. Your mileage with near-blacks might vary here, depending on the image displayed.Despite that weirdness with brightness and black crush, it's an excellent screen with a very high DPI - 1080p at 13" (170dpi) is actually higher than 4k at 27" (163dpi)! Everything looks fantastic in it, and if you're as wary as I am to buy a nice but way too overpriced 27" QHD OLED, this is a perfect way to enter the OLED monitor wave and make sure you won't burn-in these nice screens. Added benefit - the stand is quite helpful, as gaming on 13" isn't as nice as on 27", but I can just bring the INNOCN way closer to me and it's fine (though I still use my 27" for gaming regularly, so that tells you 13" can definitely feel too small). The near instant response time of OLED is super noticeable, and despite being 60hz it feels like my 95hz 27" Pixio but with better image quality (I also have a 165hz Gigabyte and despite the added smoothness that VA smear is super annoying, I'd rather have less hz but on a clearer IPS image... same logic applies to the INNOCN - perfectly clear and contrasty 60hz > blurrier 90hz with sub-par IPS contrast).If you find it at the deeply discounted $150, I say go for it. You'll get a taste of OLED monitors, see if you can "safely" use it without destroying it, and then you can move onto bigger and better OLED screens. My money is too hardly earned to gamble away $1K on a nicer screen that might get destroyed in less than a year. Looking forward to taking this INNOCN on a trip, so that I can use it as a second screen for my M1 Macbook Air.

This 15.6-inch portable OLED monitor is such a great product in so many aspects, but the ways it's lackluster prevents me from giving it a full recommendation.First of all, I wanted to comment on the color accuracy. The product actually comes with a factory calibration report of the Adobe RGB and DCI-P3 ranges. And, it shows! When I compared it using its stock 6500k color profile, which was reported to be calibrated, it matched up almost perfectly with my other calibrated monitors. This makes it a great choice for doing serious color-attentive work. That's more you can say about a lot of portable monitors...Second, the resolution for this thing is just outstanding! Pushing 4k into a 15.6-inch screen might be deemed as overkill for this size, but boy does it make it look sharp! Even at close viewing distance, it was very hard to discern any pixels. With its PPI of about 282, you can truly call it a retina display. Such a joy to any productive work, especially for general media consumption.And the build quality is just out of the park. The build is made with a high-quality heavy metal frame. It feels more similar to a premium tablet from Samsung or Apple. However, my unit's power button did have problems being pressed down. It was unnecessarily hard when compared to the clicky and normal volume buttons.It also had a respectable amount of brightness. It seemed to be just ever so slightly brighter than my MacBook's screen, which is rated at 400 nits. Keep in mind this was at full brightness.Great build, great brightness, great resolution, great color accuracy, oh and did I mention it also has a built-in battery? Though it does add a bit of weight to it, still. It's almost perfect. Almost...There were a couple of problems I had that made me have to drop it a star. One of the main problems was latency. Another plus this monitor packs is that it comes with a screen digitizer, so it can register your touches onto a device that is connected through USB-C. Though it's a great addition to what this unit already offers, it does have a half of a second lag. I am not sure if this is just a common thing with portable monitors that have touch screens, but it does create an annoyance with the device you are using it with.And for gaming, it's not the best choice. Most gamers would probably already be distraught with it only having 60 Hz, but the monitor also has a good amount of general latency for any video signal. I measured it to be about 45 ms worth of lag. It's not a big deal for any productive work, but it's noticeable in any gaming that isn't very casual. It's unusual for an OLED screen as well.It also doesn't support overclocking to its refresh rate very well. At just 65 hz at any resolution, it already started frame skipping. And it wouldn't show any picture past 71 hz. Disappointing as this also could have helped with its input lag.I really, really do like this product. I think it's one of the most jammed-packed, valuable monitors you can get for $400. Its input latency and refresh rate just became a deal breaker for me, and it may be for anyone trying to do any gaming with a mouse. If these problems are fixed, it will be a jack of all trades. Great for professionals who do color-related work, for gamers, and for everyone else who just wants the amazing contrast out of a good quality OLED panel. As of now, it's only great for two of those people. But hey, I am sure many people would not find the latency a major problem at all.If the manufacturer is listening, you did a darn good job with this product. I don't think this product deserves the 2.5 stars it currently has, as of writing this. But please, work on retaining the high-resolution while increasing the refresh rate and lowering the input latency. I also really do appreciate the custom-made OSD that works well with touch.
