Troubleshooting Common Issues

Error: Firmware Update Failed

If the firmware update fails, try the following steps:

  1. Check the USB Connection: Ensure the USB cable is securely connected to both the HDFury Linker and your computer.
  2. Restart the Update Tool: Close the firmware update tool and reopen it.
  3. Re-download the Firmware: Sometimes, the firmware file may be corrupted. Re-download it from the HDFury website.
  4. Run as Administrator: Ensure that you are running the firmware update tool as an administrator. Right-click the tool and select “Run as Administrator.”
  5. Restart Your Computer: A simple restart can resolve many issues.
  6. Check for Driver Issues: The problem might also be related to drivers. You can download the necessary drivers from the HDFury website, but it’s best to try without these drivers first. Sometimes Windows causes issues that we cannot explain. If the update still fails, try using the drivers available on the website.

Error: Device Not Recognized

If your computer does not recognize the HDFury Linker:

  1. Try a Different USB Port: Plug the HDFury Linker into a different USB port on your computer.
  2. Update USB Drivers: Ensure that your computer’s USB drivers are up to date. If issues persist, download the drivers from the HDFury website and install them as an administrator.
  3. Use a Different Cable: The USB cable might be faulty. Try using a different one.

Fixes 8/10b Downscaling for 422 Inputs

What’s New/Fixes in 0.24

  • Sony X800 support
  • HTPC mode
  • Quick preset for “disable HDR” feature for JVC projectors mainly. Hold RST and press INP 12 times

What’s New/Fixes in 0.23

  • Added 3×3 color space matrix offset capability. The range is from 0-255 added to the matrix function after multiplications. Internally scaled to support 16-bit resolution.
  • Added four EDID tables in EDID collection with HLG and Dolby Vision data blocks to enable the sources. Based on feedback we can embed into the firmware for permanent tables.

What’s New/Fixes in 0.22

  • Denon/Marantz AVR switching should be fixed. There were many items addressed with this update in this regard.
  • Audio glitching with some combo source/AVR/disc with HDCP 2.2 output is fixed. No more interruptions.
  • We still recommend using 1.4 HDCP output as always since the previous channel switch improvement with Denon/Marantz and HDCP2.2 was due to an incorrect continuous reauthorization that Denon/Marantz AVR series was making and was more of a positive symptom than anything else.

What’s New/Fixes in 0.21

  • Added CEC physical address discovery. Linker will update the advertised CEC physical address tree depending on the sink. The TOP input will be physical address 1 and the BOT input will be physical address 2. E.g. Source -> Linker (top port) -> AVR (port 7) -> TV (port 2) will give Linker CEC address as
  • If sink is removed, the CEC address remains and survives a power cycle with/without sink connected so there should be no need to resync the CEC chain.

What’s New/Fixes in 0.20

  • Switch between bypass mode (3D/PC/1080i) and HDMI2.0 modes solved.
  • AVR hotplugging revised.
  • Sink mode EDID table selection when output is not plugged (custom EDID table used when no Sink connected).

What’s New/Fixes in 0.19a

  • Test firmware for Oppo203 Owners.
  • Solved Purple Tint when player set to Auto or 4:4:4.
  • Solved Atmos and Audio loss.

What’s New/Fixes in 0.19

  • Preview RC version!
  • GUI option to shut off the HDR infoframe from the output. (GUI as “Disable HDR” Just click that and no HDR infoframe reach the display even though the input has it.)
  • Handshake now solid for all K8500/UB900/SHIELD situations.
  • Resolution switching and handshake solved.
  • Both Normal and 200% DPI GUI available.
  • Added Reset Button.
  • Remaining 1080i issue, work underway.

What’s New/Fixes in 0.18

  • Major test release: Should address K8500 Netflix issue and all other resolution/HDCP change issues.
  • Internally, the firmware has new routines to handle those situations.
  • Custom HDR and Custom AVI now survive power cycle. They are saved and automatically applied again upon power-up if they have been enabled via GUI.
  • One must exercise caution especially with the custom AVI since it can result in a blank screen if done incorrectly.

What’s New/Fixes in 0.17

  • Fixes the source BT2020 <> 709 color space change from the source when no other resync event happens.

What’s New/Fixes in 0.16

  • Added 2 new auto presets 4k30 8/10/12 -> 4k30 422 12 300MHz and 4k60 600MHz -> 4k60 420 300MHz. This is great for typical 300MHz projectors (like UB and TW series from EPSON) so that all HDR is output as 422 12 bit 300MHz except 4k60 422 12 bit 600MHz which comes out as 4k60 420 8bit 300MHz (HDR lost at 4K60 due to 300MHz BW limit).
  • This preset is also added to the Quick presets selection and the list is now as follows: The number 2/3 are new.

Quick Preset Selection

  • Normal operation, clear all 4k30/4k60 presets, clear all deep color/color space to defaults.
  • Set 4k30/4k60 presets for a 4K30 deep color projector > 300MHz (e.g., Wireless Epson) [4K30 all -> 4K30 all, 4k60 600MHz -> 4k60 420 300MHz]
  • Set 4k30/4k60 presets for a 4K30 deep color projector at 300MHz (e.g., Wired Epson) [4k30 8/10/12 -> 4k30 422 12 300, 4k60 600MHz -> 4k60 420 300MHz]
  • Set 4k30/4k60 presets for a 4k60 420 300MHz TV [4k30 8/10/12 -> 4k30 8, 4k60 600MHz -> 4k60 420 300MHz]
  • Set 4k30/4k60 presets for a 4k30 8-bit 300MHz TV [4k30 8/10/12 -> 4k30 8, 4k60 all-> 1080p60 444 8/10/12]
  • Set 4k30/4k60 presets for a 1080p60 TV [4k30 8/10/12 -> 1080p30 8/10/12, 4k60 all-> 1080p60 444 8/10/12]
  • CS follow / DC follow
  • CS 4:4:4 / DC follow
  • CS 4:2:0 / DC follow
  • CS 4:4:4 / DC 8 bit
  • CS 4:2:0 / DC 8-bit

What’s New/Fixes in 0.15

  • 4K60 4:2:2 deep color from PS4PRO (possibly other sources) fixed.
  • Fix might help on 4K24/25/30 4:2:2 deep color too (please try and report back).
  • Note that GUI still reports 8b as there is no general control packet sent by PS4PRO.

What’s New/Fixes in 0.14

  • DD+/Netflix and other audio fix.

What’s New/Fixes in 0.13

  • Input switching from the push button fixed.
  • EDID 5.1 tables moved to the end of the list (First 25 Banks, similar to Integral).
  • The BT2020 clipping issue solved when input is 4:2:2.
  • Added AVI infoframe TX disable for advanced testing (advanced users only).
  • 1080p60 Deep color upscaling resulted in > HDMI2.0 limit. Fixed.
  • GUI 422 deep color pixel clock results fixed.
  • Cleaned GUI reporting during mode changes.
  • If GUI connection lost, error message is displayed.

What’s New/Fixes in 0.12

  • Bitstream fixed. Now supports Dolby Atmos / TrueHD / DTSMA / …
  • PCM multichannel channel mapping fixed.

What’s New/Fixes in 0.11

  • Added “Display Name” information. Provides Sink device name information to the Linker GUI.
  • Added “Sink EDID Limited” warning message. When this text appears it means that Linker has detected the current incoming signal from sources exceed the connected display maximum capabilities. Linker now automatically reduces the resolution to the first supported. For example, if the incoming signal is 4K60 444 600MHz, but TV EDID says it can do MAX 4k60 420 300MHz, Linker will change chroma automatically.
  • Added “Ignore EDID Limits” checkbox. This is the override button for the above mentioned. It seems to be often the case that TV EDID advertises more limited capabilities in EDID than is actually the truth. It is likely so that TV works “better” and cables can be longer. Customers will never really know if it is 4k60 444 600MHz or 4k60 420 300MHz because all the TV will say is “2160p” in the info. Dirty games being played by big manufacturers. Anyway, with checking this box there is no more automatic downscaling/chroma sampling.
  • Added 4k60 and 4k30 Presets with Targets. There are two new preset settings: 4k60 and 4k30. These are selected using the checkbox. Then in the pull-down menu are the targets (what should happen if the input is either 4k30 or 4k60). For example, using these it is possible to force 4k60 444 600MHz -> 4k60
