Ok, first you can have a look here: https://www.hdfury.com/comparison
I'll try to summarize a few points below:
Integral is 18Gbps Splitter and 10.2 Gbps Matrix.
Linker is 18Gbps Scaler
Vertex is 18Gbps Splitter/Matrix/Scaler and can scale each channel individually as explained previously in the thread that disappeared, with Vertex ultimately you can input input 4K downscale to 1080p, apply treatment from external 1080p box to the signal and inject back into Vertex secondary channel that will upscale back to 4K at the end. this particular situation show how versatile it can be as it would require 2 Linker to do the same.
So basically it's like INTEGRAL + 2 Linker combined.
Vertex have higher signal integrity than Integral and will support more marginal cables for 600MHz.
Vertex have OLED and multiple info pages on it that will provide all information you ever wanted to have or know and those you didn't even knew they existed.
It provides more infos than Linker or Integral at first sight without need of GUI, APP or anything. it's all available at sight and from your fingertips at anytime.
Vertex also offers OSD fully customizable in colors, position, transparency, and that can be used for others purpose that signal info, removing annoying tv channel logo, or displaying custom text, etc...
Integral or Linker does not have any of this.
Vertex can cipher and decipher HDR metadata in real time, have VSIF injection/extraction/replacement, once again neither Integral or Linker have any of this. (those are for power users or content creators mainly)
Vertex have the most advanced Windows GUI we ever did, and except the fact that our GUI doesn't scale well on all display resolutions, we are known to have some of the most advanced GUI in our field.
It's oriented and made for all the guys who was in touch with us here, you can EXPORT, IMPORT and share your config with others users. once again, Integral and Linker do not have those.
I'll stop listing here, as we can add a lot of some others small things, like RS232 and possible external add ons, etc...
Bottom line: This is not marketing gimmick, we tried to build the ultimate AV toolbox and our guys worked extremely hard on it as they put all they had into it to celebrate our 10th anniversary, we are proud of work done till now on it and we believe it's a great and amazing platform and that's why we are offering a dream ticket to switch to it.
Now if you want to know, does it switch faster or sync faster on JVC PJ, or upscale quality or others stuff like that, please wait Beta testers feedback (Claw and Manni on AVSforum), as we let real non affiliated users provide such information as always.
