The Blackmagic Design Spares - DeckLink 8K Pro - HDMI 2.1 refers to the specific daughterboard or replacement interface module for the 8K Pro capture card. While the standard DeckLink 8K Pro uses four 12G-SDI ports, the HDMI 2.1 version is a specialized variant designed for high-end HDR monitoring and gaming capture workflows.

Core Specifications

This hardware is designed to handle massive data throughput for high-resolution, high-frame-rate video:

  • Resolution Support: Up to $7680 \times 4320$ (8K) at $60\text{fps}$.

  • Color Depth: Supports 8, 10, and 12-bit RGB 4:4:4, and YUV 4:2:2/4:2:0.

  • HDR Support: Full support for HDR10 and HLG (Hybrid Log-Gamma) metadata.

  • Audio: Supports up to 8 channels of embedded HDMI audio.


Functional Role of the Spare Module

The HDMI 2.1 spare is typically sought for two reasons:

  1. Interface Failure: HDMI 2.1 ports are physically more fragile than SDI. Repeated plugging/unplugging can cause the internal solder pads to lift or the "tongue" of the port to snap.

  2. Conversion/Expansion: For some DeckLink 8K Pro configurations, the HDMI 2.1 module is a daughterboard that connects to the main PCIe processing board via a high-speed ribbon cable.

When to Replace the HDMI 2.1 Module

  • No Signal at 8K: If the card works perfectly at 4K but refuses to handshake or displays "snow" (digital noise) at 8K resolutions, the HDMI 2.1 redriver chip on the board may have failed.

  • Physical Port Sag: If the HDMI cable feels "loose" and the signal cuts out when the cable is touched, the physical port housing has separated from the PCB.

  • Handshake (HDCP) Issues: If the card fails to communicate with professional monitors or high-end TVs (like LG OLEDs) despite using a certified Ultra High Speed ($48\text{Gbps}$) HDMI cable.


Technical Installation Note

Repair Level: 2 (Moderate). Replacing the HDMI module on a DeckLink is straightforward but requires care.

  1. PCIe Slot Safety: Always remove the main card from the computer before attempting to detach the HDMI daughterboard.

  2. Ribbon Cable Alignment: The link between the main processing board and the HDMI 2.1 module is extremely high-bandwidth. If the connecting ribbon cable is even slightly crooked in its socket, the card may not be recognized by the Blackmagic Desktop Video software.

  3. Heat Sink Transfer: HDMI 2.1 chips run hot. If the spare part does not come with a pre-installed heat sink, you must move the original heat sink over using fresh thermal pads. Never run this card without active cooling, as the HDMI processor can overheat in seconds.

  4. Static Control: This card uses high-speed differential pairs that are extremely sensitive to Electrostatic Discharge (ESD). Use a grounded wrist strap.


Identifying the Failure

Symptom Probable Cause
"No Hardware Found" in Desktop Video Main PCIe board failure or loose ribbon cable.
Intermittent Flickering/Blackout Damaged HDMI port or non-certified cable.
Color Fringing/Artifacts Failing HDMI controller chip (Replacement required).

Expert Advice: 8K 60fps requires a "Certified Ultra High Speed" ($48\text{Gbps}$) HDMI cable. Before replacing the hardware, test the card with a cable shorter than $2\text{m}$. Most "8K failures" on this card are actually caused by using older HDMI 2.0 cables or active cables that don't support the full HDMI 2.1 bandwidth.

Are you experiencing a total loss of signal, or are you unable to reach specific 8K resolutions?

Terrible.
Scent Name: Berry, Size: 40 Count (Pack of 1)
These do not work at all.. I used two at night and they just dissolve and my mouth is still super dry. I tried one during the day just to see and they do not help you salivate at all really. Definitely would recommend trying something else.

Xylimelts
Scent Name: Berry, Size: 40 Count (Pack of 1)
"Xylimelts - I have dry mouth from what I thought was a new medication. I stopped the medication about two weeks ago and it has not improved. I am continuing to use these until I follow up with my doctor. At first I tried these using one disk and it did not seem to work. I tried them again using two and it works a lot better. So, I now use these two disks at a time. If I use them at night, they seem to last about 4 hours. If i use them during the day, they last about 30 minutes. The effects do not last all that long during the day but I do also use Act lemon lozenges. The package says that you can put them on the gums but I put them on the roof of my mouth. I have had no issues getting any of them to stick. Flavors - At my local stores the only flavor is mint. It is way too strong. Using the mint ones would irritate my mouth after a while. Unfortunately, that seems to be the only flavor that most dry mouth products are.....mint. So my quest began to locate products that are not mint. I found these here on Amazon. They come in multiple flavors. Here is my breakdown of the flavors and my thoughts on each. Mild mint (4*) - Better than the regular mint but still mint. It is as described and the mint is not as strong. Slightly Sweet (5*) - Probably my favorite alternative to the mint. They are exactly as described. The have a slightly sweet flavor. It is not overwhelming. Berry (5*) - This was a nice change. It again is a slight berry flavor. Not overpowering or overwhelming. Cinnamon (1*) - This is probably my least favorite. The flavor was ok (it tastes like a very mild fireball) but it didn't seem to lubricate very much and after it was gone it felt like my mouth was drier than before. Orange (4*) - It has a pleasant orange flavor. Sensitive/unflavored - I have not tried this one yet. I probably will not. The reviews of the change in adhesive makes me leary to try it."

Mostly works, but..........
I use these at night for sleeping with a CPAP. I am a mouth breather, so my CPAP mask is a full face mask, thus there is constant airflow going into my mouth all night long. While these tablets do help with reducing dry mouth, they only last about 4-5 hrs before they fully dissolve - which does not get me through a full night of sleep. Using two tablets instead of one only gives me roughly one additional hour. If you wear a CPAP mask, you also need to be careful of exactly where you place the tablets, because it will be quite uncomfortable if you mask ends up pressing on the tablet. If the tablet does not adhere well upon initial placement, you pretty much need to fully dry the tablet before re-attempting placement. If the brown side is already wet when you place it against your gums, there is a much higher chance of it just sliding off, instead of sticking. Overall, while not completely eliminating the issue, they do at least reduce the dry mouth problem during sleep.

Stays put and dissolves slowly. Orange flavor is nice.
If you have to use something overnight for dry mouth definitely get these. I use one nightly with my mouth guard. The orange flavor is very nice and it dissolves slowly overnight. It's small enough to do the trick, but not be overpowering. It stays put. And it works. Definitely notice the improvement inside my mouth.

This is a seminal book on psychotherapy. A must have!
Format: Hardcover
In the age of virtual (dis)connection, concerning high rates of depression and anxiety, and the importance of self-reliance and individualism, this book comes as a lighthouse of hope and direction. Attachment Theory in Practice is a must-have for any therapist who is looking to deepen their work and bring desired transformation and change to their clients’ lives. The book provides a beautiful overview of the current state of the mental health field and the need for focusing on emotion, attachment and connection in psychotherapy. Dr. Johnson reminds us that “in order to shape optimal regulation that allows clients to harness their emotions for growth and aliveness, therapists have to ensure that clients are actively engaged with an emotional reality.” She echoes the findings from research on emotion regulation and suggests that “coregulation, rather than solo self-regulation, is the baseline, normal, and most-efficient strategy for us as social animals.” Dr. Jonson clearly posits that change is an emotional and an interpersonal phenomenon. The book also outlines very practical guidance to working with couples, individuals, and families using the the attachment framework and EFT. As a therapist who is interested in science and empiricism, I am delighted to see the tremendous amount of research support EFT for couples has received over the past decade and I look forward to learning more about the findings in the areas of EFIT and EFFT.
