SVANTTO 16” 2K Portable Gaming Monitor, 120Hz 2ms Professional Esports Portable Monitor for Laptop with FreeSync, Plug and Play, w/Smart Cover & Speakers, Lightweight Travel Monitor

This is an amazing device for the price. It works in every way I could want and then some.Bought as a floating display to use for laptops, raspberry pis, or when working on a normally headless server. It will absolutely meet those needs.Because of the price, I think it's worth confirming all of these features actually work:* Full HD resolution* Single cable operation: when connected via USB-C to a host device (PC/tablet/etc) capable of outputting video over USB-C, the monitor gets power and video over a single cable.* Power Delivery pass-thru: When connected to a laptop by USB-C and with a USB-C PD charger/hub plugged into the power port, the laptop is able to negotiate power delivery and charge at full speed. I don't know what the power limit is, but it's at least 45W.* Power over HDMI. This one shouldn't even be possible as the spec says you can only pull 300mA over HDMI, which shouldn't be enough to power a display, but it powers this one. Probably won't be able to pull enough power from every HDMI device, but it will apparently find enough with some of them. I'm watching it do so right now as I write this review. Single cable operation with HDMI. Wow.* Speakers. They aren't great. They don't get very loud. But, it has them. I missed this before ordering and was pleasantly surprised as they've already come in handy. They work over USB-C, over HDMI, and even over the crazy single cable HDMI mode that shouldn't work.Picture quality is decent overall. A very small amount of softness/"fuzziness" at native resolution when compared side by side to other displays I have. Text is very readable despite this. Probably wouldn't noticed if I wasn't comparing side by side with much higher cost screens. Contrast ratio is... meh. Gets pretty bright. I had zero dead pixels.Pros:* Build quality. Somehow it's an all-metal enclosure at this price point!? This has a minor downside (see Cons) but is mostly a huge positive. Extremely light weight, but stiff since it's all metal. Feels higher quality than I'd expect twice the price.* Matte screen. Not much glare here.* Single cable modes: USB-C and HDMI (!!!).* Power over 5V USB. When HDMI power isn't enough, you can power it off of almost any USB power source. Includes a 5V USB-A wall wart just in case.* Includes cables. USB-C to HDMI, high-speed USB-C to USB-C cable, and USB-A to USB-C cable (for power).* Extreme value.Cons:* Cover/stand. Folding cover is clever, but ultimately makes a poor monitor stand. Also, no mount points so making your own arm for this will not be straightforward.* Very electrically sensitive. Everything appears to be grounded to the metal case and touching it with any sort of metal (like while plugging in a cable) or touching it with any amount of static build-up will always cause the screen to flicker and often makes it do a full power cycle. It has always come back for me after a couple seconds, but it's both annoying and slightly concerning.* I'd always appreciate more inputs and maybe even an integrated USB hub. Absurd asks at this price, but I didn't previously think any useful portable displays could exist at this price so I'm going to dream.Conclusion/TL;DR:Literally the cheapest portable monitor I could find on Amazon. I thought for sure it was going to be a disaster at this price, but somehow it's fantastic. I hope it holds up. Sure seems like it will, unless I lose it to a minor static discharge.

Full disclosure: I'm an idiot.So, I got it primarily because I wanted to just have an extra screen for my laptop that I use for work.My laptop normally lasts about 12-14 hours (System 76; Lemur Pro).Plug and play was super easy. When I did so, it worked immediately. I went to the settings to change refresh rate from the 60hz default (59.98hz) to 120hz and it worked fine. You can tell the higher refresh rate is working since the mouse movements look smoother (I use a 240hz screen at home for playing games on my desktop).Anyways, I am an idiot for 2 reasons.1. I didn't understand how the "smart cover" worked so was just using it vertically...because it stood up on its side easily enough. My wife then looked at the pics and it became obvious. Sort of wish the instructions had a little section about how to use the smart cover....but I also get that once I realized how to use it...it's so obvious.2. The battery impact...it's enormous. I'm not sure if it's just the fact that it's a second screen and my OS (Pop! OS) isn't using power effectively (it does warn in my settings that fractional resolution would increase power use...) but my battery life dropped massively. I usually charge it once every few days. My estimated battery life went to about 50%. I guess if I drop resolution AND display frequency it would get much better life expectancy....But...but....the beauty...Anyways, it doesn't seem like a cheap item (but was...$120? I forget). I'd recommend it though I only have experience with just this. I wish there was a battery on board but that'd increase the size and weight. So I get why there isn't.I'm debating about returning it only because of that massive hit to battery life....but having a second screen for work is nifty!
