Graphics Cards

[Pirate_tat87]

First I would like to apologize if I am posting this question in the wrong thread as I'm new to this community but I do have a graphics card/upgrade question

I am currently running an HP Victus 15L Gaming Desktop 

The Graphics card that it is using is the following: AMD Radeon RX 6400

I am currently also using 3 Sceptre Curved Monitors 

1 monitor is going directly from my AMD graphics card to one monitor

The other 2 monitors are going through a (PLUGABLE USB-C TRIPLE MONITOR DOCKING STATION, 60W LAPTOP CHARGING) SKU: UD-3900PDZ

However I just now realized that the two monitors that are being connected through the plugable product are only getting a Monitor Max refresh rate of (60 Hertz) while the one being connected directly from the AMD graphics card is currently at (75 Hertz)

My question is, Does AMD make a graphics card that has max 4 HDMI outputs Minimum 3 HDMI outputs that I can use in my system? And that is up to date with my model or newer, I do know that I may need to purchase another Power supply and possibly a bigger tower, but before I do that I would like to know if AMD has such graphics card with the specifications i'm looking for? 

Thank you very much for any help and assistance!

From what I can tell most MST HDMI Hubs outputs a Maximum Frequency of 60 Hz.

This Eaton articles explains about DP 1.2 MST HUBs and the maximum monitors and frequencies it supports: https://www.eaton.com/us/en-us/products/backup-power-ups-surge-it-power-distribution/backup-power-up...

From the above link showing the different types of DP-HDMI MST HUBs which seems to have a Maximum Frequency of 60hz per HDMI monitor connected: https://tripplite.eaton.com/products/video-splitters-multiviewers-hdmi~312-1158?46270=Yes

From the link above this is the only DP - 4 HDMI Port outputs connecting 4k for each monitor at 60hz they sell: https://tripplite.eaton.com/4-port-displayport-1-2-hdmi-multi-stream-transport-mst-hub-3840-2160-4k-...

NOTE: The above is just an example. There might be DP 1.4 MST HUBS that may provide higher Resolutions and Frequencies.

Need to google DP 1.4 - HDMI MST HUBs.

Here is one from Amazon:

https://www.amazon.ca/StarTech-com-Port-DisplayPort-MST-Hub/dp/B0839LTNFK?th=1

The below Siig link gives you a chart showing the Max Resolutions and Frequencies with DP 1.4 output: https://www.siig.com/triple-4k-displayport-1-4-to-hdmi-mst-hub-splitter.html

Yes I am aware of that, that's why I am looking for a dedicated graphics card that has 4 HDMI outputs that can support higher monitor refresh rates? 

So in sense i'm trying to move away from using any 3rd party display ports,

I did find an older GPU Cards with 4 HDMI Ports which I found at this tech site: https://www.featurelens.com/graphics-card-with-4-hdmi-ports/

I didn't mention it because it is a older Visiontek RX 550 GPU Card with 4 HDMI 1.4 ports on it. AMD mentioned that all RX GPU cards are still supported but with limited drivers: https://www.amazon.com/dp/B09B83MV78?tag=voybuy-20&linkCode=ogi&th=1

Plus not sure if the technology on this GPU Card might be too out-dated for your needs.

This site gives similar or same GPU Cards with 4 HDMI video ports. Most are Nvidia and the Visiontek is the only AMD GPU card: https://techinsidr.com/best-graphics-card-with-4-hdmi-ports/

NOTE: Most modern latest GPU cards normally have both DP and HDMI ports so it will be difficult finding one. 

You might try both AMD and Nvidia Professional GPU Cards and see if any has 4 HDMI ports on it.

So if I may ask as someone that does seem to know more about this stuff then I do, Is there any graphic card recommendation that would allow me to be able to have 4 HDMI outputs, That are up to date with todays technology, or should I just forgo the graphics card and lower the one monitor that is currently at 75 Hertz and lower it to 60 Hertz and call it a day?

You can get one of the latest AMD GPUs with 2 HDMI video ports and use a HDMI Splitter each for 2 HDMI Monitors. But you will need to research to see if the HDMI Splitter will allow the type of Resolutions and Frequencies you want as an output to both HDMI Monitors.

Also the GPU's HDMI Port version must match the input HDMI Port version. As an example GPU HDMI Output Port 2.1 and Monitor's HDMI Input Port 2.1.

Googled HDMI 4k@120hz Splitters and found several that outputs to 2 or monitors at 4k@120hz.

Here is one from Amazon: https://www.amazon.com/HDMI-Splitter-1x2-4K-120Hz/dp/B0B7W94LHB

and this one at Newegg: https://www.newegg.com/p/2W9-00BC-00013

But I suggest you open a AMD SUPPORT and ask them directly which GPU Card or HDMI Splitter or MST Hub can help you from here: https://www.amd.com/en/forms/contact-us/support.html

Note: Before purchasing any HDMI Splitter or MST HUB I would first thoroughly research the hardware to make sure it fits your needs and also transmit Audio and is the same HDMI version at your GPU card and Monitor.
