Black Border with newly installed Graphics card?!

The point of that article was that unless you’re using a digital connnection (DVI - via DVI to HDMI adapter -, HDMI or Displayport), the scaling options are not available. Analogue (VGA and S-Video) and are not supported for scaling options. You will need a display capable of the aforementioned three connection ports for that to work. Otherwise, you’re going to be stuck with the black borders.

So essentially, if your DVI adapter was a DVI (to the display) and HDMI (to the GPU port), you should have had the availability of the scaling options (because that would be an entirely digital connection). If this was a VGA (to the display) and DVI (to the GPU), scaling options would still not be supported because that is not a digital connection, because of the VGA end (analogue).

Can you perhaps give us your display's model number (should be on the back somewhere)? It's possible you can adjust this natively on the display, but that's a big maybe. It entirely depends on what your display is and what its options are. We might able to look into it and figure it out. But we can't do that without knowing the specific model (and this also hinges on if the manual or specifications are still available for it online too).

@MagusMagnus , My monitor is only a VGA. So does that mean Im stuck with those borders? The display model for the monitor is S22C150N. Or the model code is LS22C150N/EN.

& @stormy13 , I will look into that and let you know Thanks!

Alright, see page 55 of your manual (here). Set it to "Wide" instead of "Auto". That's going to be your best bet to ditch the black borers (essentially, to override your GPU's setting). Hopefully, that works. There's nothing else you're going to be able to bank on in getting rid of this on an AMD card and an analogue-only display, unfortunately.

@MagusMagnus, Your amazing , a really good helper but sadly that didn't work either , I have no idea why on earth its appeared out of nowhere. SAMSUNG has told me to try the monitor with a different PC or try my PC with a different monitor. My graphics card will be taken out to see if the black border is still there when the monitor is connected to the PC's main montior port on the tower & not the Graphics card port. But its weird I've noticed Also the black border is still on the monitor even when turned off (black border isn't actually black when turned off but you can see the outline of it still.

@stormy , I tried that but it didnt change or do anything , sorry but thanks!

That certainly is weird and you shouldn't see any discoloration on a display screen, whether on or off (unless of course it was designed that way. A few are designed with a slight border around the screen edges apart from the panel frame). Perhaps your display is at fault and not the GPU at all. The timing certainly would be coincidental for it, but they can and do go bad also. On the other hand, this could also have happened from "pixel burn in"... if you've neglected the use of a screen saver. I mean, if you left the same image on the screen for a long time, the pixels can get stuck with a 'ghost' of that image indefinitely. But that seems far less likely in this case, IMO.

Well, I'm sorry I couldn't really help you. But I do hope you get this resolved.
