Problems with a RX5700

[Mason64]

Hey all wondering if this is a common problem with the RX5700 or a odd problem

I used to use the card with 4 displays 2 years or so ago. downgraded to two displays and been working great for over a year.

Decided I wanted a 3rd display again so went for a horizonal monitor (also tried another standard 27" monitor).

For some reason the graphics card will only output two monitors no matter what i tried

The card has 3 display ports and 1 HDMI port. I normally have 1 monitor on HDMI which always works and the rest on the display port ports.

I have tried the following

• loads of different display adapters that i know all work as i have had them working on this pc before and other pcs. i have also moved each hdmi cable to the 1 adapter when its plugged in and it always displays when 1 or two monitors are connected.
• tried removing the drivers and reinstalling
• tried a fresh install on a new hard drive with windows 10 and windows 11
• tried different HDMI cables
• tried the graphics card in the other PCI-E slot on the board
• moved the cables around so many times in to different ports and it always just displays two screens out of 3
• not used it much for gaming maybe in 2 and a half years used it for 30 hours gaming.
• never over clocked it.

Specs are as followed

Windows 11 Pro 64bit
AMD Ryzen 7 3700X
32GB Memory
B450 Tomahawk MAX
AMD RX5700 8gb
a few spinning drives for data and a Samung NVME Drive

Anyone got any ideas on this?

Thanks
Dave

thought i would just update the post. just got a 6600 and all 3 monitors work perfectly must be the card - strange thing is it works spot on with 2 monitors with no issues what so ever and has been for well over a year. strange.
will ebay it with the listed fault.

Thanks for your help @Orcvader
