Hi, I'm looking at getting a Sony 65' 4k TV for use as a monitor for gaming. Im using a 1080 now, and would like to move up to 2560x1440, without losing the size to go back to a 30 inch monitor, and to 4k possibly when the 800 series NVidia cards are released. I'm surprised I couldn't find an answer to this in Google, unless it's such an obvious answer I'm the only person who doesn't know it, but will a 4k tv display resolutions below 4k, as a 1080p will display anything up to 1080, will a 4k display show 1080-1440-and up etc? I'm asking because I know atm my rig won't push 4k as with most, but 2560x1440 shouldn't pose much problems in most games. Thanks for any help as I'm leaving to look at the Tv's shortly, and I won't take the advice from someone at the store trying to make commission of the sale.

It should be same difference as a 1080p monitor displaying 720p, 1080p has 2.25 pixels for every one 720p pixel.

1080/720=1.5
1920/1280=1.5

1.5*1.5=2.25

and you cant have 0.25 of a pixel so the overall quality wouldn't be as good (i think)

(because 4k has 4 pixels for every 1 1080p pixel and 1440p has 4 pixels for every 1 720p pixel, if that makes sense)


So i believe so, yes, however the quality will not be as good as a native 1440p monitor.


However if you are looking for a 1440p monitor there are some really cheap korean ones on ebay and they are supposed to be great, ive just ordered one


I should just mention that I could well be wrong

Thanks for the input, I have seen the native 1440 monitors, however I don't want to lose the size, after using a 65" tv for a monitor, I don't think there's anyway I could go back to sitting at a desk. Using it as 1440 would only be temporary until GPU's get HDMI 2.0 and can reasonably run 4k, reasonable being not needing quad titan's etc... Also since your example kind of makes sense to me, but not much, would there be another resolution that would give better quality, I only used 1440 as an example since that's the one I know, however I'm sure there are others in between. Sorry for the noobish questions, but in all my years building system I've never payed much attention to monitor's / resolutions etc.
