Problem went away for a couple months but now is back even after a new install of Windows 10.
The monitor is appearing as enabled in device manager.
Radeon Settings just seems to be crashing and freezing on me whenever I try open it. I'll attempt to reinstall and see if there are any settings which can be changed which will fix this issue.
Why are you not running both monitors from the card ?
The same problem over 3 OS's, sounds more like your setup or hardware problem.
Your not still using virtulogic software.
Since the problem occurred again, I switched to running only one monitor (on the card). Issue went away and came back.
I'm running only a single monitor now off the card and am still getting this issue. I get a low screen resolution on startup and the native resolution can't be chosen from windows display settings. Through a few more startups, I can eventually choose 1920x1080 however it is blurred.
Attempting to create a custom resolution within Radeon Settings to 1920x1080 doesn't work as it says the setting is not compatible with my monitor.
If I run the monitor off the motherboard all these issues go away however.
So what is exact Samsung model (monitor, hdtv, or the hybrid) ?
And to save people wasting their time searching , supply the product page link.
It's a montior and it's model is listed in the first post. Samsung Syncmaster 2333.
I'm not sure what you want, I'm pretty sure it's a discontinued Samsung item.
Do you want it's specifications?
Samsung SyncMaster 2333SW Specs - CNET
Also you said "Your not still using virtulogic software". Should I be using it? The only page I found was on an intel website for a download for a Windows 7 version of it. Do you have a Windows 10 download link? Is it only for Intel motherboards?
There is no new virtu (so forget it). There are/were 3 2333 models (T, SW, HD).
Check monitor osd settings, cables (no adaptors ?), don't reconnect other monitor.
Maybe try "reset factory defaults" in crimson and a Clean Install AMD Graphics Drivers
I got nothing else.
Oh I didn't realise there were 3 different models, sorry! I've tried all your suggestions to no avail.
Thanks for you help though!
Back to amdmatt , he might have something new to offer.
Or you might try on tenforums.com/ (try their search for "multiple monitors" or "resolutions change").
So I thought I solved my issue by downloading Custom Resolution Utility (CRU) which allowed me to modify the resolutions available so I could add my monitor's native resolution (1920x1080).
However after restarting my computer, AMD settings didn't like it and started conflicting with it. AMD settings keeps trying to lower my resolution down to 1600x900 while Windows or CRU attempts to set it back to what it should be.
This essentially prevents me from using my computer until disconnect the monitor and plug it into the motherboard where the issue doesn't occur and then I have to kill all the AMD processes. Plugging it back into the GPU after this keeps it at 1920x1080.
Previously I thought this issue might not be connected to AMD and Radeon software and drivers, however this pretty much confirms it is.
