Do the wireless HDMI transmitter and receiver support 4K?
Yes, wireless HDMI supports 4K@30 for high-quality graphics. If the signal source is 2K@60, it automatically changes to 2K to fit the display. It works seamlessly with 1280×720, 1920×1080, and 3840×2160. Blurriness may be due to signal interference.

Why is the wireless HDMI transmitter disconnecting?

Effortless setup, reliable 4K wireless hdmi ttransmitter kit
For my Zoom studio I needed to send the video feed from my computer to and external monitor and a large screen TV… my computer and camera are on a Mobile card, so I wanted to reduce cables so I decided to try this wireless transmitter. It worked great, and the kit included all the cables it needed for connecting the HDMI and the USB-C for power. No drop out ( not a far distance) very happy. I was worried if there would be issues with video delayed but it works fine and and now is can see what I need for my presentations

some defects
For the streaming as Netflix, transmission are not very stable with a lot of frozen images, even when they are in HD and with a short distance between them. Nota : house wifi was disconnected to check if it have influence !
Bottom Line Up Front –
Awesome 4K caster
Bottom Line Up Front: This is one of the few wireless HDMI kits that actually delivers on what it promises. It has crisp 4K video, low latency, and truly plug-and-play setup. It’s become a go-to in my workspace for casting my laptop to a big screen.I’ve tried a few wireless display solutions before, and most are either finicky to set up, laggy, or limited to 1080p despite saying “4K” on the box. The RGBlink Ask Nano actually does full 4K output and runs impressively smooth for presentations, Zoom meetings, or streaming a quick video clip in a group setting.Setup is as easy. Plug USB-C on the laptop, HDMI on the display. That’s it. No drivers, no apps, no manual pairing. Once powered on, the signal locks in with no visible delay, and the audio syncs perfectly.A few small notes: it doesn’t include a power adapter (just the cables), so if your TV or monitor doesn’t have a USB port for power, you’ll need your own charger. Also, while the latency is excellent for business use and videos, this is not a solution for gaming. There’s a slight delay that would throw off fast inputs.Pros:-True 4K output with no visible lag-Instant connection, no software required-Supports extended screen, not just mirroring-Works well even from across the room-Compact and travel-friendlyCons:-No included power adapters-Not ideal for gaming or high-speed input tasksIf you’re looking to ditch HDMI cords in a conference room, classroom, or even a home office, this is one of the most reliable options I’ve tested. Highly recommended.

Fantastic for movies and basic web browsing, NOT recommended for gaming, no power adapters included.
First of all, super happy that this is an actual 4k Tx/Rx, because most of these have “4k support” but only transmit a 1080p signal. This does a full 4k signal, and so it’s awesome for using to watch movies and things of that nature. It’s truly plug and play, and works great for watching movies. However, there is a perceptible lag, and so it’s definitely not recommended for gaming.The reason I gave it -1 star is because it states the following in the description: “when powered by included 5V1A adapters.”, however, NO POWER ADAPTERS ARE INCLUDED! So, that can be a bit of a pain if you don’t have a compatible plug to power these with. In fact, the included cables are pretty short, so you may end up needing not only power adapters but longer cords to power them with.The description should be changed to reflect the fact they don’t come with adapters.Overall, though, they work very well and are super easy to set up and use. Just be aware they’re not for gaming, and you will need to power them. 4 stars.

Reliable wireless HDMI extender with sharp image quality and strong value for money
This plug-and-play kit worked flawlessly right out of the box. It wirelessly transmits crisp 4K video up to 30 meters with minimal latency—perfect for smooth business presentations or classroom setups. The build quality is solid, and pairing the transmitter and receiver was fast. Functionality is top-notch for the price, especially compared to higher-end competitors.

Surprisingly Solid Wireless Display Solution—Finally One That Just Works
I went into this with low expectations, since I’ve been burned by wireless HDMI kits in the past—they’re usually clunky, laggy, or just a nightmare to set up. But this RGBlink unit really surprised me in the best way.Setup was basically nonexistent. Plug in the transmitter and receiver, and they sync automatically—no pairing, no driver installs, no fiddling with settings. It just worked. That alone was a breath of fresh air. What really makes this one stand out is the USB-C output on the sending end. It opens up a lot of flexibility, especially if you’re using a modern laptop. I was able to use it not just to mirror my screen but to actually extend it and run a second display wirelessly. That’s something I’ve never had work smoothly with other kits in this price range—or even higher. Latency is low enough that it’s a non-issue for presentations or general use. I haven’t tried gaming with it (and probably wouldn’t), but for meetings, casting content, or setting up an extra screen across the room, it’s been rock solid. If you’ve been frustrated with previous wireless HDMI devices, this one might just redeem the whole concept for you. It did for me.
