questions about running my 75 inch 1080P tv in 1440P

hey guys so this is a little bit of a head scratcher for me.. I recently bought a really nice 4k Gsync monitor and Ive been having fun messing around with the resolutions seeing how 1440p looked on it etc.. and so anyway Ive been playing the first dark souls game on my pc lately, and unfortunately it only supports 1080P so when I play it with my 4k monitor it really doesn't look very good because its not the native resolution...

anyway long story short, I ended up hooking the pc upto my 75 inch Samsung 1080p tv to play it because it looked much nicer, and after I had it hooked up for a while I decided to try to force some different resolutions, and I found that I can force a 2560x1440 resolution on to the tv. I don't understand this at all.. because it actually does make my desktop and more importantly, my games look a lot nicer than when I set it to 1080P....

How is this possible?!? lol and also am I risking breaking my tv at all?

How are you forcing 2560x1440? Sounds like it might be Nvidia DSR, which renders at a higher resolution but then downscales before sending the image to the display.

nope. I know all about DSR. this isn't that. If you go into your Nvidia control panel you can set resolutions not natively supported by your monitor/tv.

Control panel/Change resolution/ then below the different listed supported resolutions youll see customize. then you can play with it. you can even overclock your monitor to higher Hz than what is natively supported, though I haven't had any luck doing that with my particular monitor or tv.. just the resolutions.

sorry, but a 1080 panel cant be "forced" to run 1440. a 1080 tv or monitor or phone or any kind of screen will only have 1920 horizontal by 1080 vertical pixels. you can't add more pixels by a setting in your control panel.
as for your original problem, yes scaling older games that don't support 4k will not always look great. and monitors don't have the same upscaling features as say a 4k tv.

Im well aware that you cant change the amount of pixels, but you can definitely force your monitor or pc to display 1440p its called downsampling. Im just curious exactly how this works and if its possible that it will hurt my display at all.

shoot I didn't mean to pick yours as the solution haha I meant to reply to you again :/ ah well.. on further reading, I realize that what I am doing is pretty much the same thing as DSR, its just a different way of going about doing it! So I guess in away you were correct 😛 whats different I guess is that this works for everything on your pc rather than just games. As far as I can tell anyway its close to the same thing.
