Hello everyone,
i know it's a lot of text and information... so thank you all very much in advance for your time and effort.
First a little bit of background:
I've had this problem for a long time now and had contact with the display manufacturer, MSI support and i also tried numerous forums to get a solution, which obviously did not help since i'm writing this here. It was okay for watching videos so i just gave up in 2017, but the situation has changed and i would like my secondary display to work correctly again, because pdfs and programming scripts are horrible in 640x480. I've been looking around again and tried different approaches and i am at a point where i don't know any further.
The problem :
There is only the 640x480 (60 Hz) resolution available for my 2nd display. Main display works fine. Setting something else with adrenalin (custom resolution) or tools like CRU does only result in "no signal" error on the display. Windows device manager shows 1st display as PnP monitor and 2nd display as non-Pnp monitor.
The "fun" part:
After fiddling with settings for a few days again, deleting and installing drivers and changing resolutions via CRU, i have now reached a stage in which the display hast the correct solution after startup juuuuust >>until radeon software loads<<. Then both screen flicker once and it shows "no signal" on 2nd display again. Uninstalling radeon software package is not the solution, because then the main monitor doesn't work correctly.
tl:dr:
- start pc -> device manager shows 1st monitor pnp, but native resolution; 2nd monitor non-pnp with 640x480
- after changing "non PnP-monitor" resolution with CRU to native 1280x1024
- start pc -> native resolution on both displays until a few seconds later
- radeon software loads up -> displays flicker, then 2nd display "no signal"
See troubleshooting below.
System:
MSI RX 480 armor 8Gb
Win 10 Pro N 64bit
Ryzen 7 1700X on a MSI X370 gaming pro carbon
32 gb DDR4
drivers and bios are up to date
1st / main display: Asus PA238 (connected via DP or HDMI)
native 1920x1080; 19:9
2nd / secondary display: fujitsu scaeloview H19-1 (connected via DVI-D)
native 1280x1024; 5:4
monitor input supports analog (vga), analog( DVI-I) or digital (DVI-D, but no dual link bc pins are not connected)
Troubleshooting:
- display works well on pc with nvidia gtx460. It worked on a system with radeon 5770 and catalyst drivers.
- changing to different DVI cables does nothing
- connecting only 2nd display does nothing
- Installing .inf does nothing or gives "no signal" if it contains information about timing/resolution
- clear installing driver package/ radeon software does nothing
- clean windows installation does nothing
- deinstalling drivers via device manager does nothing
- a few resolutions have worked during different radeon-software-versions since 2017, but never the native resolution (in 2017 1280x720 worked, but was fit to fullscreen, which was horrible as well)
- using different custom resolution tools (integrated adrenalin feature or CRU) does result in the display showing "no signal"
- GPU scaling on/off does nothing, except if a custom resolustion is set then on keeps 640x480 and off results in "no signal"
- deactivating virtual super resolution does nothing
- windows device manager event "Not migrated due to partial or ambiguous match"
- MonInfo does not show 2nd monitor, but multiple entries of 1st monitor (live, reg-active, reg)
- Radeon software correctly identifies the names of both monitors. Device manager does not and shows pnp-monitor (1st display) and non-PnP-monitor (2nd display).
I hope this covers everything so far, if anything is missing feel free to ask

This website has your Fujitsu Monitor manual: Changing The Monitor Settings - Fujitsu Siemens Computers SCALEOVIEW H17-1 Operating Manual [Page 21...
Do you have your Monitor set for Digital Input:
Using your Monitor's OSD Menu:
Make sure your Fujitsu Monitor has the correct 60 hz frequency and Resolution under Windows Settings - Display.
Also check to see if you have a Fujitsu Monitor driver to download from Fujitsu Support.
What happens if you disconnect the first Monitor and just use your Fujitsu Monitor as the Main monitor. Do you still get the low Resolutions or the Native Resolution?
All the Monitor Driver for your Fujitsu are provided by Driver Updaters so it was useless.
Went to Fujitsu and inputted a slightly different Model E19-7 and downloaded their Windows 10 WHQL driver from 2015. See if it will work on your Monitor. The E19-7 seems to have the same Resolutions as your older model: Fujitsu Technical Support pages from Fujitsu Fujitsu Continental Europe, Middle East, Africa & India
I downloaded and attached it to this post if you want to download it to your computer and see if your Non-PNP Monitor now shows Fujitsu Monitor. Then see if you are able to get the correct Resolution on your Fujitsu Monitor.

Thank you very much, sadly no solution yet.
It even switches back to digital automatically after setting it to analog

Nothing changes, even after restart. Still low resolution and "non-PnP-monitor" in device manager.

Neither 59 nor 60 Hz work and 75Hz aren't even listed, thought it's capable of 1280x1024 @75 Hz
The driver you attached/linked did not work. It goes directly into "no signal" mode.
Thanks for your time and comment
I was finally able to borrow another PA238 and try around for a bit.
The combination of of 2x PA238 works fine in either combination (except HDMI, possibly because the cable seems to be defect; single monitor on HDMI did not work). 1xDP and 1xDVI-D works, but on the DVI-D-connected monitor the color- and pixelformat-information is missing in radeon software and MonInfo. Sadly i forgot to take a look at the device manager to see if the DVI-D is listed as Pnp or non PnP-monitor). Will do again when i get the chance.
With 1xPA238 connected to DP and the H19-1 to DVI-D the H19-1 isn't even showing in MonInfo, but the radeon software lists it as "H19-1" in the display-section.
So ... maybe there's something going on with the EDID, which in turn leads to some sort of default monitor, which then leads to some conflict between some windows magic and/or radeon default monitor stuff? As written before it works for a brief moment until the radeon software loads up, if i override the resolution with CRU before the restart.
Also, i'll update if there's news/ideas from the ticket. (as far as i'm allowed to do so)
If you can connect PA238 and H19-1 models to your graphics card one by one without any problem, it is not necessary to search for the problem with the display driver or with the graphics card. So there is probably incompatible. And an converter adapter can solve your problem. But I cannot guarantee it. Adapters look like that...
If graphics cards with DVI(-D) support were produced for multi-display support, these graphics cards would be released with more than one DVI port. But in almost all of the newly released graphics cards, I could not see any DVI port. Existing types only have "one" port.
Actually I changed too many graphics cards. There were single VGA outputs, VGA + DVI outputs, VGA + DVI + DVI-D outputs, DVI + DVI-D outputs. But I did not have a graphics card with two DVI-D outputs. Multi monitor support has already come up with HDMI for me.
Multi display support of graphics cards with single DVI support via DP or HDMI probably depends on GPU manufacturer and monitor firmware, I think. And this's probably why it doesn't work for you.
Also you can try WIN+CTRL+SHIFT+B shortcut to reload firmwares of the monitor. I saw those who had problems because they did not use this shortcut.
