PC Graphics

RX 6600 wont display on more than one screen

I've got a new custom built pc that i finished building last month. I have two monitors both VGA -> Display Port, both are plugged into their own ports on the back of the GPU. But no matter what I've tried, there's never more than one screen with display on it. It's primarily my biggest monitor that works, to get my smaller one to display i have to load into safe mode / disable the driver whilst I'm in there. But then the 2nd screen goes off. I can only assume its an issue with the GPU seeing as these monitors work completely fine on my old pc with the same cables. I'm completely lost on what to do here.

If both are right side cables, you may need one with a converter on the left (passive one should work on up to 1080p).

Am I to assume you already looked in your display settings and enabled the other monitors as clones or extended?

Yup, I've had a look at the display settings, tried cloning / putting the display on just the monitor that's got no display in normal. Absolutely nothing.

I simply did not see your post. It is unfortunate that you have been or had been experiencing issues. This is primarily a user forum. I do not work for AMD. I volunteer my help, with moderating this forum with a few other users.

The post you linked gave me no information about your specific hardware configuration. Without that information I can not even begin to troubleshoot the problem you are or were facing. Here is a link to the required information when posting. https://community.amd.com/t5/knowledge-base/information-required-when-posting-a-discussion/ta-p/4227...

I understand your frustration, however I personally have zero experience with the RX 7000 series and do not try to help others with hardware I know very little about. You are free to use the form at this address https://www.amd.com/en/forms/contact-us/support.html to speak with AMD directly. 

I hope you find a solution and wish you the best.

all good, cheers  

Some more info on your system might help.

OS & build version?

What are the monitor resolutions, DP cables versions, passive or powered adaptors?

What was old pc graphics card?

Ryzen 5 5600x, B550 aorus pro ac, Hyper 212 black, 2 x 16gb F4-3600c16dgtzn kit, NM790 2TB, Nitro+RX6900XT, RM850, Win.10 Pro., LC27G55T..

I'm on Windows 11 Home my build version is 22621.2134
Monitor Resolutions Are:
1920 x 1080 (monitor that primarily works)
1366 x 768 (monitor that only works with driver disabled or in safe mode)

Display Port Cable Versions I think are both 1.2 or 1.4
Looks like the cables are passive but I'm not too sure.

Old PC is telling me the GPU it used was 'Intel® HD Graphics 4600'.
