Default what is going to work, what do I need

Day Trading Station

Monitor 1: 31" 4096x2160 @ 60Hz
Monitor 2,3,4,5,6 24" 1920x1080 @ 60Hz - at a later date 2 of the 24" monitors will be replaced with 4k monitors 3840x2160 @ 60Hz

The monitors display stock tickers, stock charts, chat rooms, etc.

Any help/suggestion what I should get is much appreciated

Thank you

Hello videogeek,

Let's start with the most restrictive requirement!
To get 4Kp60 over DisplayLink technology, you need a device using the DisplayLink DL-6950 chip. That chip can handle up to two 4Kp60 heads. You have several products announced with this chipset: Targus Dock160, Dell D6000, Wavlink USB-C Ultra 5K Universal.

Then, using DisplayLink technology, you can daisy-chain... That's how we showed our trading workstation at different shows with 6x4Kp60.
To get the maximum number of displays and minimise cost, you might be interested in getting boxes doing 2 or more displays. The ones mentioned above are all capable to do dual heads.
The Dell D3100 based on an older chipset can do 1x4Kp30 over DisplayPort and 2x1080p over HDMI.
You have multiple products using DisplayLink technology supporting 3 heads but the third display is using another technology so is not universally available on all platforms. As it's not using DisplayLink technology, you must check the datasheet of both the product and your computer to make sure the third head will be usable.

Because your type of content seems fairly simple to encode, I don't foresee the need for a very high end host machine. Of course, if you're expecting to play video on an external 4K, you will need a beefy machine: we don't require a special chip on the host machine (that's why we can offer a universal solution), but we need some CPU to encode the content...
No solution comes free of computation: whether CPU or GPU, someone has to do the work to compute these pixels!! Anyone claiming to give pixels free of any effort on the platform is probably disingenuous.

Kind regards,
Alban
