HDMI to DisplayPort Adapter Not Working

Although we have provided a great list for dealing with faulty HDMI to DisplayPort cables, we suggest that you seek extra advice from a professional. Now let’s get started and find several ways to get your adapter working.

1. Get the Best Connection

As you use an HDMI adapter, ensure that you have the best connection. After all, this setup allows the adapter to provide the best video and sound.

You can get started by fixing one end of the cable into the HDMI out port while the other end goes into the DisplayPort In port. As you perform this task, insert both ends of the adapter firmly into the required ports. Also, ensure that the adapter’s cable is not tangled or bent at a weird angle.

As you push the cable into the ports, do not use extreme pressure. After all, too much force can mess up any of the pins.

2. Use a Compatible Device

Do you want to connect the HDMI cable to your VR Gaming Headset? Would you like to hook up your gaming console to a cinema display? If yes, do not use an HDMI to DisplayPort Adapter.

By design, these devices cannot work as they are not compatible with an HDMI to DisplayPort Adapter. So even if you use the best adapter to work with these devices, you might not get the expected results.

You can handle this problem by working with the right electronics for your adapter. For a proper list of compatible products, check the owner’s manual of your preferred brand of HDMI to DisplayPort adapter.

3. Do Not Forget the USB Cable

If your HDMI to DisplayPort Adapter has a USB cable, you might have to connect it to a power source. After all, the adapter might require some energy to convert the needed signals. If you are not sure of how to carry out this task, check the instructions on the owner’s manual.

4. Get an AC Adapter for the Nintendo Switch

With the HDMI to DisplayPort adapter, you can connect the Nintendo Switch to a monitor. But before the adapter can produce audio and sound, the gaming system will need its original AC adapter to provide power. If you have lost this Nintendo Switch accessory, you can pick a replacement from a trusted store.

5. Perform a Power Cycle

Sometimes a power cycle is the best solution for a poor HDMI to DisplayPort connection. To use this solution, you can try the following steps:-

6. Enable the DisplayPort Settings

As you connect the HDMI to the DisplayPort adapter to the Display 1.2 monitor, it should automatically detect the device and apply the right settings. However, some monitor brands might require some manual adjustments before providing pictures and sound. If your monitor does not come on especially after connecting the cable, head to the settings and turn on the Display Port 1.2.

7. Check the Owner’s Manual

Most HDMI to DisplayPort sellers choose to provide manuals with their products. Normally, these documents include the best ways to use and troubleshoot the adapters.

Supposing you have an annoying HDMI to DisplayPort issue, you can whip out the manual and check for the ideal solution. But if you can’t find the manual, you will have to contact the customer service desk of your chosen adapter brand.
