Does the HDMI 1.4 Port Support 4K Resolution at 60Hz?
No. The port complies with HDMI 1.4, and as such 3840x2160 (4K is only achievable at 30Hz. 2560x1440 and all lower resolutions will display at 60Hz.
Can I Connect a DisplayPort (DP) Monitor to the HDMI Port on This Device Using an Adapter or Cable?
No. Most DisplayPort to HDMI cables and adapters are one-way adapters from a DisplayPort Source (computer or docking station) to a HDMI Sink (television, computer monitor, or projector). These cables do not work in reverse.
DisplayPort uses packet-based data transmission, breaking the video stream into individual packets of data allows for longer cable runs, use in both copper and fiber-optic cables, and allows for higher bandwidth than other video formats. It is relatively easy to convert from DisplayPort to HDMI (computers with HDMI output ports already do this internally) and dual-mode DisplayPort outputs have built-in adapters to output a HDMI signal for use with passive DisplayPort to HDMI adapters.
HDMI uses a video signal, similar to DVI, this requires more power to operate at the same cable lengths as DisplayPort and requires significantly more processing power to create DisplayPort packet-based data.
Externally powered HDMI to DisplayPort adapters do exist, these generally have a USB or small barrel plug for power, and can convert from a HDMI Source to DisplayPort Sink. In most cases they have reduced resolution or refresh rates compared to modern signal sources and can introduce delay in the data connection between the display and computer potentially causing reduced connectivity or display performance problems.
We do not currently recommend using HDMI to DisplayPort adapter with our docking stations. In our testing they have been unreliable compared to a native DisplayPort connection. Many of our newer docking stations include both HDMI and DisplayPort outputs to reduce the need for additional adapters or adapter cables.
What Streaming Software Can I Utilize With the NIX Capture Card?
Since the NIX Capture Card utilizes drivers that are baked or already present inside of Windows, macOS, and Linux—essentially appearing as a webcam—it will work with most major streaming software such as OBS, StreamLabs OBS, XSplit, Wirexast, and vMix.
For additional information regarding the streaming software you utilize, if not present in this list, please reach out to us directly at support@plugable.com
Which Port on the NIX Capture Card Do I Connect My PC/Console To?
The NIX Capture Card has two individual HDMI ports: One for "In" and one for "Out".
The "IN" port should be where you connect an HDMI cable from the source (Xbox® One, PlayStation® 4, etc) to this port.
What Is the "Out" Port For?
The "OUT" port can be connected to a display so that you can see a live feed of what is being sent to the "IN" port.
This way you can still view the output from your HDMI source at the same latency as it would be when directly connected to the display without dropped frames or lag.
Which cable inside the box do I use to connect the NIX Capture Card to my computer?
There are three total cables/adapters included inside of the box with the NIX Capture Card. One is a standard USB 3.0 to USB 3.0 cable. This can be utilized on most modern systems, and will allow you to connect the capture card, and communicate with your capture software.
The second cable is unique, as it allows a USB Type-C (USB-C) based system (such as a laptop) with a native USB-C port to connect to the NIX Capture Card. One end is USB-A (which connects to the Capture Card) and the other is USB-C, that you connect to a compatible USB-C based system.
We also include a small USB-C male to USB-A 3.0 female adapter. This can be utilized to combine both the USB 3.0 to USB 3.0 cable, on a system that a USB-C port.
When disconnecting the source HDMI cable from the capture card, and then inserting another new source, the NIX Capture Card doesn't show anything in OBS. How do I fix this?
A bug in OBS can cause this to sometimes occur. The best way to resolve the issue is to right click the "Video Capture Device" source (or the unique name it was given) and select properties.
Inside of properties, just below the "Device" drop down box, you should see a "Deactivate button". Click the Deactivate button, and remove the HDMI cable that is connected to the "IN" port on the capture card.
Wait 5 seconds, and then reconnect the HDMI cable from the source system to the "in" port on the capture card. Once reconnected, right click the "Video Capture Device" source (or the unique name it was given) and select properties. Once inside properties, click the "Activate" button and you should be back up and capturing!
Can I Output 2560x1440 (1440p) or 3840x2160 (4K) content?
No. The NIX Capture Card only supports a maximum resolution for input and output of 1920x1080 @ 60Hz.
Does the capture card support higher refresh rates for pass-through to my 75Hz, 100Hz, 120Hz, or 144Hz monitor?
No. The NIX Capture Card only supports a maximum resolution for input and output of 1920x1080 @ 60Hz. Even if your display and devices support higher refresh rates, they will not function through the NIX.
With the PlayStation® 4/PlayStation® 4 Pro connected, an image appears on the display connected to the "out" port, but not inside of my streaming software. What should I do?
The PlayStation® 4/PlayStation® 4 Pro system utilizes HDCP protection by default when the console is turned on. To disable this feature, select (Settings) > [System] and then clear the checkbox for [Enable HDCP].
When using a macOS system to capture video/audio from my source device, the audio seems to sound incorrect or "choppy", How can I resolve this?
This is most likely a problem with the Hz rate the audio for the capture card has been configured as. Please follow these instructions:
- On your main macOS Desktop, at the top left, look for the finder bar and click Go
- Click an empty space on your Mac desktop, or open a Finder window, if you do not see the Go menu
- Locate and select Utilities
- With the Utilities menu now open, locate Audio MIDI Setup and double click the icon
- Once inside of the main Audio MIDI Setup menu, locate the FHD Capture device, and click to highlight it
- Once highlighted, look for the drop down box next to Format and ensure that a 48,000Hz sample rate has been selected
- Once the correct sample rate rate has been selected, close out of Audio MIDI Setup and head into OBS
- With OBS open, locate the OBS listing on the top left of your macOS Desktop. Click it, and select Preferences
- Once the Preferences menu has been opened, on the left side locate and select the Audio option
- Inside of the Audio menu, please ensure that the drop down box next to Sample Rate has been properly set to 48KHz
- Once the drop down box is correct, click OK on the bottom right hand side of the menu, and restart OBS
Audio Sync Issues in OBS
To address audio sync issues, try the following.
In the bottom of your OBS Window, there is a frame/section called “Mixer". Scroll through the list and look for the audio input capture line item (usually a unique name you added when adding the Audio Input Capture Source) and click on the “COG Wheel, or Settings Wheel” on the right. Select “Advanced Audio Settings”.
A window should appear showing you the name of the device, the volume bar, and other various settings. Look for the Audio Input Capture item name you configured, and in the column that says “Sync Offset” input 470ms (for some devices the magic number will be between 470-480).
The video should now be synced to the audio being captured.

macOS
OBS Configuration
Before configuring the capture card, please have the latest version of OBS installed. Recent macOS updates may cause problems with OBS if you are not using the latest version.
This guide will walk through the steps to initially configure OBS's recording and preview settings.
- Enter the Settingsmenu of OBS
- Method 1—Settings button in the lower-right of OBS
- Method 2—In your Mac menu bar, open the Preferences menu and choose Settings
-
Method 3—Press ⌘ + ,
- Switch to the Output section of the Settings window
The Video Bitratevalue is one of the most important items to configureBitrate Value Best Use/Notes 2,500 Kbps OBS Default 8,000 Kbps 1080p at 24, 25, or 30 frames per second 10,000 Kbps Max upload for most cable Internet providers 12,000 Kbps 1080p at 50 or 60 frames per second
When streaming video, it is important to keep in mind what your max available upload bandwidth is for your Internet connection. If you are playing an online multiplayer game, maxing out your available upload bandwidth can lead to performance problems in your game.
It is also important to note that the Video Bitrate does not include the additional bitrate of carrying audio. By default, OBS is configured to use 160 Kbps for audio. For example, selecting 8,000 Kbps—with the default audio bitrate of 160—results in a total bitrate of 8,160 Kbps.
If Enable Advanced Encoder Settings is enabled, it is important to note that the Encoder Preset which ranges from ultrafast to slower mostly impacts how much processing work your computer has to do during the capture/streaming process.
If you are on a high-performance computer, using the slower options may be feasible and will result in better video quality. However, if you are on a lower-performance system, you will likely want to choose one of the first three options. - Switch to the Audio section of the Settings window
- One of the most important settings regarding audio is the Sample Rate setting. If the sample rate between your console, the recording device (the capture card), and OBS are mismatched in any way, it can result in issues like audio popping, audio cutting out, and a variety of other audio issues.
Usually the best approach is to set everything manually to 48KHz, including this option in OBS. Please note, that you must restart OBS for this change to take effect.
Additionally, you will want to enter the Audio MIDI Setupmenu of macOS. This utility can be found by searching Launchpad on your Mac:- Select FHD Capture and make sure the Format is set to 48,000KHz
- On your computer, game console, or other HDMI source that you are capturing audio and video from, make sure to check the audio output properties on that device and manually set it to 16-Bit 48,000Hz audio
- In OBS, click Apply in the lower-left of the Settings window, then click OK
- In the Sources section of the main OBS window, click the + symbol to add a device
- In the menu that appears, choose Video Capture Device
- In the dialog that appears, you may rename Video Capture Device to whatever you want, such as 'Nix HDMI Capture Card'
- After clicking OK a new window will appear for the properties of the newly-added video capture device
- Perform the following changes and checks in order:
- Ensure that the device you intend to capture from is plugged into the Inport of the NIX capture card
- Please Note—The NIX HDMI Capture Card does not support HDCP (High-bandwidth Digital Content Protection). Your source must not enforce HDCP. Last-generation game consoles such as the Nintendo Switch and Xbox One do not enforce HDCP for most gameplay and/or on the dashboard/home menu. However, most media playback apps such as YouTube, Hulu, Netflix, Amazon Prime Video, and other video/audio streaming services will cause HDCP to become active. On the PlayStation 4, there is a toggle to switch HDCP enforcement on and off
- Verify that the device you're capturing video from is not in a 'sleep' state, and has a video signal being sent to capture
- Uncheck Use Preset
- In the Device dropdown menu, choose FHD Capture
- In the Resolution dropdown menu, choose 1920×1080
- In the right-most dropdown for Frame Rate choose 30 or 60. 30 is recommended for higher detail quality and 60 is recommended for smoother motion in fast-paced games
- After selecting the Frame Rate, video should appear in the current window
- Scroll down to the next options in the Properties window
- Make these additional changes after scrolling down:
-
Input format
- By default MJPEG will be selected, this is a very low-quality recording option, and is the only one available if your NIX Capture Card is connected via a USB 2.0 port
- In the dropdown, select YUY2 - 422YpCbCr8_yuvs. This is the highest quality input format, and is only available if your NIX Capture Card is properly connected to a USB 3.0 port
-
Color space and Video range
-
Color space and Video rangeare much more difficult to configure than the other options that have been selected so far. Televisions, and devices designed to connect to televisions, use a somewhat complex system to determine black levels, white levels, and color values when composing and displaying an image. These settings have a dramatic impact on color accuracy, and the brightness, of the image being captured
- On consoles and televisions, color spaceis often given as three options:
- Wide
- Limited
- Automatic
- On consoles and televisions video range is usually given as an HDMI Black Leveloption:
- Low
- High
- On consoles and televisions, color spaceis often given as three options:
- For the best quality in capturing video, previewing the capture, and viewing the passthrough from the HDMI Outport on your monitor or TV, it is very important to test which combination of these settings results in the best image quality. You may need to manually change settings on:
- Your game console or other capture source
- Here in OBS
- On your display connected to the Out port of the NIX Capture Card
- Here are some general tips regarding these settings in OBS
- Start with 'Rec. 709' for the color space
- If black portions of the captured image appear too 'light' or 'gray' select Partial for the Video range
- If black portions of the captured image appear too dark/lacking in detail, select Full
- If the image still seems very incorrect, check the video settings on the device you're capturing video from

How To: Set the Display Refresh Rate in Windows 11
Many modern displays can support above the default 60Hz refresh rate, however this may need to be manually set within Windows 11. Please note, not all computers, graphics adapters, and docking stations can support all resolutions and refresh rates.
Setting the Display Refresh Rate in Windows 11
1. Right-click on the desktop and select Display Settings from the drop-down menu
2. Scroll down to the Related settings subsection and select Advanced display
3. At the top of the Advanced display window, select the external display from the drop-down menu
4. From the Choose a refresh rate drop-down menu select the desired refresh rate
Refresh Rate Limitations
With Windows 24H2 and newer, dynamic refresh rates are supported, this allows the system to adjust the display refresh rate to save power, up to the selected refresh rate. As a consequence of this new mode, when selecting the display refresh rate you may see an asterisk. This indicates that selecting the specific refresh rate may reduce the display resolution or image quality in order to prioritize the refresh rate. This exposes the refresh rate option from the display even if the display cable or computer is incapable of supporting that refresh rate at the native resolution and is the intended behavior per Microsoft. [1]
In the screenshot below the left side shows the 4K 120Hz capable display limited to 60Hz refresh rate without asterisks, and on the right the same display after setting the refresh rate to “120 Hz*”, the “Desktop mode” resolution has been reduced to 2560 x 1440 (1440p) instead of 3840 x 2160 (4K UHD). Unlike when using the display scaling option this also causes a reduction in image quality. On the right side asterisks are no longer shown in the refresh rate list. Setting the refresh rate back to 60Hz does not change the resolution, you will have to go back one page and set the resolution manually.
