I have a Dell UltraSharp U2516D which supports 2560x1440 @60Hz mode.
Highest options Windows 10 will show me (from Display Options and also the List All Modes box) are 1920x1080 and 2048x1080.
I've installed the latest drivers for my card NVidia GTX 560, from the NVidia website.
I'm using a DVI - HDMI cable to connect (HDMI port on monitor, DVI from graphics card).
What can I do to troubleshoot this? Many thanks for looking at my problem. :)

Looking it up... maybe my graphics card doesn't support HDMI 1.3 (I don't know, can't find stats on it, and it doesn't make sense that my card would not support a version of HDMI). HDMI 1.3 or something is required to do 2560x1440.
(EDIT: Although HDMI 1.3 came out in 2006 so it doesn't make sense a 2011(?) card would not support it. Not sure how necessary it seemed to NVidia at the time, though.)
The screen also has DP and mDP, do you think DVI to DP would work better? Is that even a real thing. (Graphics card only has DVI output).
-
Likely you need a Dual-Link DVI connection. However "Adapters" don't usually support Dual-link DVI which results in a limited resolution. You would need to either replace the card with one that has Display Port or HDMI 1.4 and use the appropriate cable to connect to the monitor, or replace the monitor with one that supports Dual-Link DVI. (Former is probably more affordable...)

Yeah I bought a "good" monitor, so probably cheaper to replace the graphics card. Oh well, bit of a shame, not end of the world... I would like to get that full res.
Could you by any chance recommend a GPU in the same kind of performance range or better? I guess something around the £100 mark or lower (so... like $150 or lower bearing in mind market/exchange differences if you're not used to UK market).
Thanks for the reply, whether or not you can help with choosing GPU. You've saved me at least a trip to the store trying to fix something else that can go wrong!
EDIT: and furthermore I tried out a different card and it works in here, going to keep it there until I figure out what to buy for them. Not using my primary computer atm so I can live like this for some time. Thanks again, has been very helpful getting a useful informative answer like this.

I'm seeing GT610's on Amazon.ca for $44 Canadian so it might be similarly inexpensive on .co.uk or on other sites. (or brick and mortar).
For the most part I'd expect any graphics card that has a HDMI or Display Port connector would at least be equivalent to the 560.
-
A GT610 is significantly weaker than a 560, you would need to go higher end than that to get something comparable. Looking at used cards on the likes of eBay may also be worth a try. You may also want to consider returning the monitor and getting one that supports DVI as this may work out cheaper.
What model of 560 do you have? My old 560ti didn't have a full size HDMI port but it did have miniHDMI. Not sure if this would support 1.3 or not though.

Right, I forgot the second digit is more significant than the first for Nvidia model numbers.

The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface.
It was announced by Apple in October 2008. As of 2013, all new Apple Macintosh computers had the port, as did the LED Cinema Display.[2][not in citation given] The Mini DisplayPort is also fitted to some PC motherboards, and some PC notebooks from Asus, Microsoft, Lenovo, Toshiba, HP, Dell, and other manufacturers.
Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 (WQXGA) in its DisplayPort 1.1a implementation, and 4096x2160 (4K) in its DisplayPort 1.2 implementation. With an adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.[3][4][5]
Apple offers a free license for the Mini DisplayPort[6] but they reserve the right to cancel the license should the licensee "commence an action for patent infringement against Apple".
EDIT: Note that is says:
Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 (WQXGA)...

IIRC it's a GIGABYTE GTX 560 (not TI).
It has 2 DVI ports and 1 mini HDMI. So good idea yeah, I could try with a mini HDMI (would have to borrow/locate one). Seems plausible.
