The P50 unit features a 4K icon next to the indicator light.

 

To use it, as shown in the video I tested for you, all you need to do is plug the TX unit into the source device, then use a USB-A to USB-C cable to supply power.

 

Similarly, the RX receiver is plugged into the TV, projector, or in general, the display device.

 

Lemorele P50
The P50 has the following basic specifications:

• 4K30 transmission

• 50ms latency

• Up to 50m transmission range

• Supports multiple receivers simultaneously

I first tested the P50 with a MacOS source, since that’s what I use most often. However, on MacOS, the P50 couldn’t transmit in 4K30 — it only supported 1080P60.

During usage, the P50’s latency was acceptable. It handled 30fps video playback smoothly, with no stuttering or lag.

 

 

 

In both the article and the video, I used a USB-A power source from a power bank, but you can also use a USB-A port directly from your PC or from a monitor that has a USB port — that works too.

I also tried using the P50 with a desktop computer, but it didn’t work very well. When moving the mouse quickly, the input lag becomes noticeable, which negatively affects the overall user experience.

 

 

Interface when TX and RX are not yet connected

So, if you’re using it for presentations — on a large screen, TV, or projector at a distance — it works fine and is totally acceptable; the latency isn’t bothersome to the eye.
However, when using it as a monitor directly in front of you, especially for desktop computing, you’ll definitely notice the delay when moving the mouse quickly.

 

 

The HDMI connector on the device is a bit bulky, so when plugging it into a PC or monitor, it may not fit well — I had to use an additional HDMI cable with a slimmer connector.

Secondly, when I tested it with Windows, the P50 was able to output 4K30, but during use, I noticed a bit more lag. The latency was slightly noticeable, so overall, it’s still most stable when running at 1080P60.

 

 

 

 

When first plugged in, the device automatically defaults to 1080P30 or 1080P60 — you’ll need to manually adjust it to 4K30 if desired.

As for distance, I haven’t tested the full range yet, but within a range of under 10 meters, the P50 performed stably with no stuttering or signal drops.

 

 

By default, the P50 package only includes one extension cable, so I had to prepare an additional one in case the connector didn’t fit properly.

Lemorele P20

The P20 has a configuration quite similar to the P50:

• 1080P60 transmission

• 50ms latency

• Up to 50m transmission range

• Supports multiple receivers simultaneously

The Lemorele P20 is the set I’m currently using. It runs stably on both macOS and Windows at 1080P60 resolution, and the performance is quite smooth.

However, similar to the P50, when used for presentations on a large screen at a viewing distance, it works well and is stable. But when used as a computer monitor at close range, you’ll still notice some mouse

 

 

 

Conclusion
In short, I just wanted to introduce to you that this type of device exists in various configurations and formats — the Lemorele P20 & P50 are just options I happened to test and found to be available for purchase in Vietnam.

You can use these wireless video transmission kits as an alternative to messy cables and complicated setups, helping keep your workspace cleaner and more organized.
