Ótima imagem. Mas o som deveria ser melhor.

I bought this monitor about 10 months ago and was very happy with it until a few weeks ago. The picture and build quality are really nice and has a built-in stand that folds out. I mostly use it as a TV screen for my Roku and Tivo but I also sometimes take it on travel with my high-end MSI gaming laptop. Both are pretty heavy but still fit in my large computer backpack. I had no complaints whatsoever until one day the monitor just died. No picture, no LED power light, nothing. I tried multiple power supplies, cables, etc. and it definitely was the monitor. I tried to contact Innoview through their web site but for some reason, their online contact form was not working so I had to contact them trough Amazon. I was expecting a ton of headaches trying to actually get a hold of Innoview's tech support and trying to get the unit replaced. I figured they would have me jump through a ton of hoops and expect me to send the dead monitor back (with me paying shipping) and would take a month or more to get the replacement. On the contrary, Innoview's tech support emailed me not more than 24-48 hours (it was a weekend as well) later, asked some basic troubleshooting questions (which I had already done), my Amazon order information and a picture of the plaque on the back with serial/ model number. Within another 24 hours, I got an email saying they were shipping me a replacement! Within a day or two after, another email with the tracking number. I am so pleased with Innoview, both the quality of their monitor but also the incredible (especially these days) experience with their tech support team! If/when I buy another "portable" monitor, it will definitely be from them again.

This was my first time purchasing a portable monitor and to my surprise this item has been excellent! Been using it as a second monitor for work and have been loving it! I love the portability aspect of this item. The monitor is a crisp high resolution display and the sound comes through clear as well. The 4k makes the images vibrant. The monitor is light but yet feels like a sturdy build. Definitely recommend to anyone looking for a portable display monitor!

As a "HDMI" monitor, this merits 4 or 5 stars. As a DisplayPort Alt-Mode (DPAM) monitor, it deserves one star. Let me explain why... and why it took me several months of frustration to finally get to the root of the problem. I purchased my monitor back in early December 2024. It's badged as "Innoview", but "Monitor Asset Manager" revealed "YCT" as the actual manufacturer, and "YCT5AA1" as the underlying model number. I also purchased a bidirectional DPAM cable. The OVERWHELMING majority of "USB-C DisplayPort" cables sold on Amazon are NOT Bidirectional... they work to connect a USB-C source (like a phone) to a DisplayPort sink (ie, monitor), but they can NOT be used to connect a DisplayPort source (like a Nvidia GPU in a desktop PC) to a USB-C sink (like THIS monitor). And I'd say at least 1/4 to 1/2 of the cables on Amazon that are CLAIMED to be "bidirectional" actually aren't. I literally went through three cables before finding one that worked. This is not the monitor's fault, but it's something you ABSOLUTELY need to be aware of when shopping for a cable. Now... getting to the reason why I'm so critical of this monitor's DPAM capabilities: it uses a RealTek RTD2851 scaler chip, and whomever developed the monitor's firmware BADLY screwed up the setting that governs its power-saving timeout behavior. As sold, from the moment the monitor powers up, it has approximately 1 second to see a valid source connected before it goes into power-saving mode and shuts itself off. The problem is, negotiation of a DPAM connection takes time... and can, in fact, take longer than the RTD2851 is willing to wait before going into powersave mode. Even worse, pressing side-buttons (to bring up and navigate its menus) DOES NOT extend the time window. You can literally be in the middle of madly mashing buttons, and when that 1-second timeout rolls around... the monitor will turn off. The net result is, the only way to reliably use DPAM with this monitor is to ALSO have a live HDMI video source connected at the moment you power up, in order to keep the monitor from going to sleep before the DPAM handshake completes. OK, so let's suppose you don't mind having to carry and connect TWO video cables wherever you go (keeping in mind this is supposed to be a PORTABLE monitor), to ensure that you can always bootstrap the monitor using the HDMI cable to keep it alive long enough for DPAM to handshake & allow you to switch to it. Let's suppose you have an AMD Ryzen 9 motherboard that allows you to connect the HDMI cable to that, and the DPAM cable to your RTX videocard. Every time you power up, you have approximately 50-50 odds of the monitor deciding to use the HDMI connection instead of the DPAM connection, regardless of what your last-selected connection was. I can assure you that this gets REALLY tedious and annoying after a while. I personally bought the monitor to use with my eBlaztr portable ITX gaming case. As a monitor for an eBlaztr, it can be great... it fits perfectly (though you'll need to add ~1cm spacers to the VESA bolts to shift it slightly away from the case), and looks good. But the need to always carry a HDMI "jumper cable" to bootstrap the monitor and force it awake long enough for DPAM to handshake is SERIOUSLY annoying. Eventually, I made ANOTHER bad discovery about this monitor, which led me to abandon DPAM altogether and settle for HDMI: this monitor CAN NOT DO VRR, FreeSync, AdaptiveSync, or G-Sync when connected to a Nvidia GPU. The problem is, the RTD2851 scaler chip is CAPABLE of those modes, but doesn't ADVERTISE them via EDID. Nvidia's drivers WILL NOT even ATTEMPT to use variable framerates unless they see that data in the EDID block. Period, end of story. I've spent months looking for ways to hack it. To the best of my knowledge, as of July 2025... if you use this monitor with a Nvidia GPU, you WILL NOT be able to use VRR or Freesync. In theory, AMD GPUs *can* be coaxed into doing VRR/FreeSync/AdaptiveSync by overriding the EDID via software configuration... but I didn't spend $800 on a RTX 4070Ti Super just to settle for the motherboard's intergrated graphics. So as far as MY computer is concerned... the monitor can't do VRR/FreeSync. In the end, I think I'm being EXTRAORDINARILY generous by giving this monitor 3 stars, because the timeout and EDID problems I mentioned effectively render it unusable for USB-C DPAM in general, and Freesync/VRR with Nvidia GPUs in particular. If, by some miracle, Innoview had some way to provide a flashable firmware update to correct those two specific problems, I'd give the monitor 5 stars. As it stands, they're incredibly lucky that I'm nice enough to let them have three just because it's one of the only 24" UHD monitors presently available AT ALL (as of July 2025) in the US, and it's decent as a HDMI-connected non-gaming monitor for people who NEED the specific combination of "24 inches" and "UHD" (like, eBlaztr owners). TL/DR: 1. If you have a Nvidia GPU and want a monitor that supports VRR and/or Freesync... do NOT buy this monitor. 2. If 4k60 (without VRR/Freesync) via HDMI is an acceptable compromise, it's a nice monitor... especially considering the nearly total and complete lack of alternative options for 24-inch UHD

Bought the monitor and was working great, until it didn’t…. would not turn on at all. contacted the manufacturer via email directly and received very responsive and helpful support in attempt to fix the problem…. after few more email exchanges, the Innoview support team decided to replace the monitor. I felt they really tried to help, and I am grateful that they will replace the monitor. Very good monitor for being portable & received great support.
