Radeon R7 series 200, HP ZR30w monitor, dual link DVI cable but locked at 1280x800 resolution rather than 2560x1600

Apparently 1280 x 800 is the monitor safe mode.

Check your manual/settings/connections..

Does your video card have a DisplayPort port?

Unfortunately, no; it has only DVI, HDMI, and VGA.

Odd...Anyway, are you sure the cable is Dual Link, and that you are using the correct refresh rate?

My cable has a manufacturer's label that says "Dual Link DVI cable part no X058C" (I think it's a Dell cable).  Windows is only giving me a single choice of refresh rate: 60 Hz.

Try it without the drivers.

without which drivers? If you mean the monitor drivers... I had already

tried it without them (didn't work), then added them as an experiment.

Tried another cable?

Yeah I think that's a good next move. Will locate another one and let you

know.

Tried a different cable.  Same result. 

How can I be sure that this Radeon card actually supports what I'm trying to do?  And that it's not broken?

What is the exact make/model of card (GPU-Z has a Lookup function) ?

The GPU-Z Lookup goes to this page:

https://www.techpowerup.com/gpudb/b2479/xfx-r7-250 which says XFX R7 250

Based on this page

http://xfxforce.com/en-us/products/amd-radeon-r7-200-series/amd-radeon-r7-250-core-edition-r7-250a-zlf4,

it looks like that trying to use DVI is my problem! It says Max Supported

Resolution (DIGITAL) : 1920 x 1080(DVI);4096 x 2160 (HDMI)

I wonder if an HDMI to DisplayPort adapter would do the trick?

You're going to be limited to 30hz if you use the HDMI port. Ideally you need to upgrade your graphics hardware to a model with a DisplayPort. I'd suggest the RX 550, it's twice as fast as the 250 and has a DisplayPort and HDMI 2.0b
