As in the question. Most descriptions show 4K, 6K, 8K and 30/60hz. I would like to ask a question about get FullHD resolution with 144hz at the Displayport 1.2 output only on one monitor.
In the worst case, it should support at least 120hz.
Hello @kubako1428,
Thank you for taking the time to ask your question here on the StarTech.com Community page.
I can take a moment to break down some of the differences and capabilities between these adapters.
Here is a chart I have put together to compare these these adapters.

This chart is based on the Technical Specifications for these adapters on the StarTech.com website.
The manuals for the USB32DP4K and the USB32DPES2 do not differ in the resolution specifications. However the manual for the USB32DP24K60 has a couple additional notes.
Supported resolutions
at 60Hz
3840x2160 (60Hz), 2560x1600
at 120Hz
2560x1440 (120Hz), 2048x1152
at 144Hz
1920x1200, 1920x1080, 1600x1200, 1680x1050, 1600x900,
1400x1050, 1440x900, 1366x768, 1360x768, 1280x800, 1280x768,
1280x720
Note: Lower resolutions are also supported at each specified refresh
rate.
You can find this in the product manual linked on the drivers and downloads section of the USB32DP24K60 Product page.

In your question, there is a reference to DisplayPort 1.2. I would like to caution that while the USB based video adapters do use DisplayPort ports, and will work with most DisplayPort 1.2 displays, there is no official DisplayPort 1.2 reference in our product materials. It will be best to consider them based on their capabilities as listed in the Technical Specifications rather than based on the video standard.
You had reference 4K, 6K, 8K, 30/60hz also. While there are some video resolution and refresh rate limits with these adapters, I did not see references to 6K, or 8K when I was reviewing our USB based video adapters. We do have some Thunderbolt docking stations with 6K or 8K video support.
Based on my complete review here, the USB32DP24K60 will be a fit for you. It is supported in Windows, macOS, LTS Ubuntu, and Chrome OS. and will normally require a driver installation.
Please let us know if you have any other questions!
Sincerely,
Thank you very much for such an extensive answer. I will be happy to use the USB32DP24K60. I would like to additionally ask about potential delays. I am aware that the display time will not be the same as on dedicated video outputs, but in a configuration of 3 monitors in the game where the adapter will be responsible for the side one, will it be “strongly” felt, or will I have to sit down with a magnifying glass to notice the delay? Of course, when using 1080p/144hz. Thanks again for your reply. Have a nice day 
Hello @kubako1428,
Thank you for your question.
Another point to highlight is the notes in the Technical Specifications:
- This USB video adapter is not intended for graphical intensive applications, such as gaming
I have not noticed any lag with the technology used in the USB32DP24K60 on standard desktop applications. However, I have tried earlier versions of this technology with some lower demand games and some lag was noticeable. I might anticipate some lag with the USB32DP24K60 depending on the games.
Based on my understanding of the USB-based video technology this is because the USB32DP24K60 has it’s own graphics system that uses software and the computer’s CPU to render video rather than the GPU. There is some level of interaction with the GPU on your system but the results could vary.
While we do not recommend the USB32DP24K60 for gaming, you are welcome to test it out. You could experience considerable lag depending on the the game, the output demands, and the capabilities of the system.
Please let us know if you have any other questions.
Sincerely,
