Radeon R7 450 Three Monitor Support

[BeauBeach]

According to the product specifications, the Radeon R7 450 OEM video card provided in this system is capable of supporting up to 3 monitors (native) or 6 (daisy chain).

I attatched the following;

HP S2031 via DVI-D

LG FULL HD via Display Port to HDMI (passive)

SANYO HDTV via HDMI

Any 2 of the three monitors will work simultaneously, however I cannot enable all 3

Please advise a workaround for this problem

The Driver (provided by AMD) ;

AMD Radeon (TM) R9 M360

ver 22.19.165.1

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand you need information about Radeon R7 450 Three Monitor Support

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Have you updated the drivers for your graphics card & installed the latest BIOS?

While you respond to that, here's a few things you should know:

Connecting multiple monitors for AMD Eyefinity technology couldn’t be simpler. There are four easy rules to remember:

1. The first two monitors can connect to the graphics card with any display output on your product: HDMI, VGA, DVI or DisplayPort.
2. The third (or greater) display must be connected to the graphics card via DisplayPort.
3. If your monitor does not have a DisplayPort connection, you will need an inexpensive active DisplayPort adapter for it.​
4. Every family of GPUs supports a different maximum number of displays.

That said, here's an HP Article that should guide you through the steps to resolve your concern: CLICK HERE FOR INSTRUCTIONS.

Keep me posted for further assistance 😉

I read this article to no avail.

According to HP Assistant, both my video driver and BIOS are up to date.

After updating my video driver using the HP Assistant, the Video card Shows as "AMD Radeon (TM) R9 M360" even though the installed card is the AMD Radeon R7 450 (unless the wrong video card was installed in this system)

The configuration is as follows:

HPS2031 Monitor connected via DVI-D (native)

SANYO HDTV connected via HDMI (native)

LG Full HD connected via DisplayPort using DispayPort to HDMI adapter (passive)

Each monitor works independently, or in combinations of 2

When attempting to enable all 3 monitors through the Windows10 dispay settings, all three show up as detected, but only 2 can be enabled at a time.

When attempting to enable all 3 monitors using the AMD eyefinity configuration, only 2 monitors show as detected.

According to AMD, the R7 450 only supports 2 monitors simultaneously, however also according to AMD every video card produced after 2013 is Catalyst enabled to support 3+ displays. According to HP it supports up to 6 (3 native, +3 daisy chained from the Display Port)

Thank you for replying with this overwhelming and detailed response 😉 

I appreciate your time and efforts,

It looks like using the display port directly instead of an adapter should do the trick,

I would request you to connect the cables directly rather than using converters or adapters as that would be the best way to fix your concern.

Let me know how that works out, keep me in the loop and Good luck! 😉

[BeauBeach · Accepted solution]

After filing a complaint with a lawyer and the Better Business Bureau, an HP support representative was able to help me with this issue.

The R7 450 is equipped with 2 available GPU clock cycles

What this means is that the NATIVE support for this device is two displays

That being said, there is a workaround for this product. By using an ACTIVE DISPLAY PORT++ (1.2) ADAPTER OR HUB you can connect between 3 and 6 total displays

An active adapter provides 1 additional GPU clock cycle capability

An active hub provides up to 4 additional clock cycle capability

NOTE These are additional parts that are more costly than cables. The computer, as shipped, can only support two displays simultaneously. Also, you cannot use a PASSIVE adapter in this case, it must have the additional clock cycle capability to allow multi-display support greater than two.
