Love these screens!
These screens are the absolute best. Makes working from laptop so much better and having 3 screens allows to get done the work done easier!! So easy to set up, light weight and durable. Easy to throw in bag with laptop when traveling too. Picture quality is great too!! Overall, the best thing I’ve purchased for laptop! I did have an issue where the usb c > usb/usb c broke. I reached out to customer service via email. They sent me a new a cable and back to business I am! The turnaround time to receive was 3 days, which was amazing considering the time difference and via email!

Perfect quad monitors!
UPDATE #2: The seller has been absolutely phenomenal to work with. Evidently the monitors I received had a technical issue and the seller immediately sent me replacement monitors. The new monitors work perfectly and now I couldn’t be happier. Kudos to KYY for how they handled this situation. I now highly recommend this product now that I know KYY stands behind what they’re selling. UPDATE: The monitors have hinges on them that allow them to unfold more, so they do work with my laptop. The hinges are so tight that I felt like I was going to break the monitors when trying to unfold them. I started using the monitors and they’re actually pretty great, however, when I leave them plugged into my laptop and do a reboot, my laptop BIOS enters a continuous loop saying that memory training is in progress. And this most recent time, it caused my laptop PIN and fingerprint to be erased. This is super concerning and I’m afraid these monitors are going to have to go back. Original: Not wide enough for my 17” LG laptop even though the description says it will fit up to 17.3”. VERY disappointed.

Instant productivity in an extremely portable package
KYY Model X90G Triple 15.6” Monitor Review I’ve been using KYY’s dual 14” monitor for a couple of years and had great luck with it, so I decided to try their larger, triple-monitor X90G. There’s a lot to cover here, so stick with me. Packaging & Setup KYY does a great job with packaging, and this product was no exception. The monitor arrived securely in a sturdy retail box. Inside, everything was neatly organized: the monitor itself, all the necessary connection and power cables, and a USB drive with drivers (which I didn’t need for Windows 10 or 11). First Impressions The build quality is excellent. The aluminum frame, strong kickstand, and sturdy hinges keep the screens exactly where you want them. It’s a solid piece of equipment, and at just over 6 pounds, it isn’t something I’d want to carry around every day. However, it’s perfectly manageable for extended setups or car travel. Folded up, it looks like a slightly thicker laptop. Once opened, you’re surrounded by a massive amount of screen space. The Full HD resolution is sharp, with vibrant color. Display controls include a full suite of settings like HDR, blue light reduction, and several presets, including options for gaming. The menus are easy to navigate, and brightness can be adjusted directly without diving deep into settings. Although the 400-nit panel initially felt dim, I quickly found that 35% brightness was more than sufficient and actually more comfortable, especially when working close to the screens. Display Configuration & Use You can configure the monitors for use as a workstation or for presentations. I haven’t tested the presentation features, but I regularly use the wing monitors for programs like Outlook or Teams, while the top center screen is ideal for my primary work. It’s a seamless setup that complements my main monitor very well. Final Thoughts This is a thoughtfully designed tool that boosts productivity, adds flexibility, and makes multitasking much easier. It’s a solid investment if you're looking to expand your display space. Highly recommended.
