I had been using another coupler and I was getting less than 100 Mbps speed. Hence I decided to try Ugreen coupler. I had bought a 1000Mbps and this one. Both saved me from the hassle of changing the entire cable.

Overview
UGREEN 40238 is an active, one-way converter for connecting an HDMI source—such as a computer, console, Blu-ray player or camera—to a monitor or projector that accepts DisplayPort. It combines an HDMI input lead with USB power and a female DisplayPort output. The specification supports up to 4K at 30 Hz or 1080p at 60 Hz and carries both video and compatible digital audio. A separate DisplayPort cable is required.

Features
What it does well.
Signal direction cannot be reversed
This adapter accepts an HDMI source and feeds a DisplayPort monitor or projector. It will not connect a DisplayPort computer to an HDMI television. A separate male-to-male DisplayPort cable and a stable USB power source are required to complete the connection.
Key features
Converts in the uncommon HDMI-source to DisplayPort-display direction.
Supports up to 3840×2160 at 30 Hz or 1920×1080 at 60 Hz when source, cable and display agree.
Carries compatible HDMI audio and video through to the DisplayPort display path.
Driver-free active conversion for normal supported operating-system display modes.
Attached 0.5 m HDMI lead and 0.5 m USB power lead.
Works with duplicate/mirror or extend modes when the computer and operating system support them.
Use scenarios
Reuse a DisplayPort-only office monitor with a laptop or desktop that has HDMI output.
Connect a compatible game console or Blu-ray player to a DisplayPort monitor.
View an HDMI camera feed on a DisplayPort-equipped screen.
Add a second DisplayPort screen to a computer whose available video output is HDMI.
Present slides on a DisplayPort projector from an HDMI-equipped source.
Setup and usability guidance
Switch off or sleep the source and display before making the first connection.
Connect the adapter’s HDMI plug to the HDMI output on the source device.
Connect a separate DisplayPort cable from the adapter’s female DP socket to the display’s DP input.
Connect the USB lead to a powered USB port or suitable 5 V USB supply; using power is recommended for reliable conversion.
Select DisplayPort on the monitor, then choose duplicate or extend mode and a supported resolution on the source.
Compatible devices and systems
The source must provide HDMI output; the receiving screen must provide DisplayPort input.
Suitable source categories include PCs, laptops, consoles, Blu-ray players and cameras with standard HDMI output.
A computer can use mirror or extend modes if its graphics hardware and operating system allow them.
DisplayPort cable quality and monitor capability must support the selected mode.
Real-world performance and planning
The successful mode is negotiated across the HDMI source, active converter, separate DisplayPort cable and receiving display. All four parts must support the selected resolution, refresh rate, colour format and protected-content requirements. For first setup, begin at 1080p / 60Hz, confirm a stable picture, then select 4K / 30Hz if every endpoint supports it.
USB on this assembly is power only. It does not send graphics or install a virtual display device. When a screen remains blank, check the one-way signal path, attach USB power, select the monitor's DisplayPort input, reseat the separate DP cable and restart the HDMI source before changing advanced picture settings.
Check before buying
Source device must have HDMI output; the screen must have DisplayPort input.
Add a separate standards-compliant male-to-male DisplayPort cable.
Plan for 4K at 30Hz or 1080p at 60Hz—not 4K/60, high-refresh gaming or VRR.
Provide stable 5V USB power and confirm the display supports the chosen video and audio mode.
Warnings and limitations
4K is limited to 30 Hz; use 1080p for the listed 60 Hz mode. Actual choices depend on EDID negotiation between source and display.
Connect the USB power lead for dependable active conversion, especially when the picture is blank or unstable.
A separate DisplayPort cable is mandatory. Buying only this adapter will not complete the connection.
Audio requires the source, converter path and DisplayPort display to support the same format; a monitor without speakers will not produce sound.

FAQs
Questions buyers ask.
Can I connect a DisplayPort laptop to an HDMI TV?
No. This adapter works only from an HDMI source to a DisplayPort display. Use a DP-to-HDMI product for the opposite direction.
Does USB carry the video?
No. HDMI carries the source signal; USB supplies operating power to the active converter.
Is a DisplayPort cable included?
No. A male-to-male DisplayPort cable is required and sold separately.
Will it output 4K at 60 Hz?
No. The listed ceiling is 4K at 30 Hz. The listed 60 Hz mode is 1080p.
Can I extend my Windows desktop?
Yes, if the computer’s HDMI output and graphics settings support an additional display. Select Extend in the operating-system display settings.
Does it support sound?
UGREEN lists audio and video transmission. The source audio format and the DisplayPort monitor’s audio capability must also be compatible.
Why do I get a blank screen?
Confirm direction, attach USB power, select the monitor’s DP input, reseat the separate DP cable and begin at 1080p/60 Hz.
Will a passive HDMI-to-DP cable do the same job?
Usually not. HDMI-source to DP-display conversion requires active electronics, which this powered adapter provides.
Can it improve picture quality?
No. It converts the interface; it cannot create detail or refresh rate that the source does not output.
Can I use a USB phone charger for power?
A stable 5 V USB source is generally appropriate, but the power supply itself is not included and should be compliant and undamaged.
Can I use it with a game console?
Yes, when the console provides standard HDMI output and the monitor accepts DisplayPort input at a compatible mode. Start with 1080p/60Hz. Console-specific protected content, HDR, high-refresh or variable-refresh features are not guaranteed by this 4K/30Hz adapter.
Does the converter need a software driver?
The active converter itself is driver-free for normal supported display modes. The computer or console still needs a working HDMI output, and a computer user must select mirror or extend mode in the operating system. USB is used only for power.
