I have an AMD Radeon Quiet HD 6450 card (details below).
But I have just bought a monitor with 2560 x 1440 WQHD resolution.
Is my card powerful enough to use this monitor? Or do I need a new graphics card?
It can provide up to 2560x1600 with dual link DVI, but you won't be playing any games with it.
That's great, thanks for your help.
Apart from playing games is there anything else I won't be able to do with it?
Will I be able to watch YouTube videos that are recorded in 1440?
This resolution would depend on the ports which the card and monitor provide. Generally, only DVI Dual Link (DL) and DP ports can enable a 2560 x 1440 WQHD resolution.
You would need to check on the specifications of the monitor as to which connections the monitor needs to use to enable that resolution. Most monitors with that specific "max" resolution require a DVI Dual Link connection to utilize their full resolutions.
If the card has a DVI Dual Link connection (check with the card manufacturer) then you will be able to run that natively (using a DVI DL > DVI DL cable). The only other option would be if the card comes with a Display Port which you could then use a DP > DVI DL adapter. If that is the case you can check www.amd.com/dongles for AMD approved adapters from DP > DVI DL (if this is only the first or second screen you are connecting then you would only need to get a "Passive" adapter and not a "Active" one).
From what I have seen the HD 6450 cards generally only have 1x DVI Single Link (SL) + 1x HDMI + 1x VGA. If that is the case then you would not be able to get this resolution. I have seen a couple versions with a 1x DP (replacing the 1x HDMI) so if you have one of those you should be able to get it working with the above guide. I would suggest visiting the page www.amd.com/connectors if you would like to confirm if the card has a HDMI or DP (as they do look very similar).

The only (silent) 6450's I can find on the 'net' have a Dual-link DVI connector. Even the specs on the AMD site say it has Dual-link: http://www.amd.com/en-gb/products/graphics/desktop/6000/6450#
Wow, it's getting complicated!
My new monitor inputs are 3 x HDMI and 1 x DP (but no DVI).
My AMD card outputs are 1 x HDMI and 1 x DVI-DL.
So I guess to use my monitor's 2560 x 1440 WQHD resolution I need to buy a DVI-DL >>>> DP cable?
Something like this?
Assuming the panel is OK, HDMI can support 2560x1440 at 60 fps easily
you do need a super speed cable, some cheaper cables may not work well
You may find the HD 6450 struggling with video at that resolution and you might want to get a more recent R9 series card
You would need to confirm with the Monitor manufacturer that the HDMI port supports UHD first off.
Also this would require HDMI 1.3 or higher to support 2560 x 1440 (so if the card only has HDMI 1.1 then it would not work). You would need to check with the Card Manufacturer as to which port they installed. From what I can see (in your screenshots) it looks like your card is possibly from Sapphire.
Technically you cannot adapt any other port "to" Display Port. Display port can only be used as the "output" source. As such it looks like your card would not be able to connect correctly to this monitor in order to enable the max resolution. In the screenshot you included it read "Displayport to DVI-D Cable..... Converts from .... DisplayPort to DVI-D.
As such you would ether need to get a card with a DP (to use with that monitor) or a monitor which has DVI-DL port.
Now I'm really confused!
The screenshot for the cable states it is bi-directional and that it can be used from DVI>>>>>DP and also from DP>>>>DVI.
Isn't that okay?
A passive DP adapter cable is only useful for dual mode DisplayPort on the host side - as a passthrough to the circuitry that supports HDMI, DVI, or VGA. Your host end (the graphics card) does not support DP, so that cable is useless for you.
The 6450 supports HDMI 1.4a, which has enough throughput to support 2560x1440@60 easily, so you should just use the HDMI connection. No monitor new enough to include DP is going to have an HDMI revision below 1.3, which is where support for that resolution became available.
As "Thanny" stated, DP adapters are not bi-directional even if the page claims they are. Only DP > mDP cables are bi-directional.
Could you please give your monitor model information so we can check on the input/resolution presets built into it.
