Downsampling vs 4k monitor

#1Darkblade9116Posted 7/17/2014 4:02:28 PM
Hi,
I keep hearing about the rise of 4k. I've seen some videos and images, and indeed they are (somewhat) sharper.

I'm wondering: will you be able to achieve the same quality by downsampling an hdtv (1080p) to 4k, as a native 4k from a 4k monitor?

In any way, would my to be system even be able to smoothly run games in 4k?

i7 4790k
Gtx 780 3gb
16gb ram 1600mhz

Thanks in advance

maybe at 30fps tops, probably less. Even 780 ti's in sli struggle with 4K right now. GPU's just aren't powerful enough yet.

Ah, ok thanks. And my other question? Does downsampling have the same effect as a native 4k monitor?

If by that you mean effect on performance, then downsampling from 4K should because the GPU is rendering at 4K regardless.

No it won't, what you will get is smoother edges, but you'll see a softening of the image due to downsampling a higher-resolution image to your lower resolution screen. A higher number of physical pixels will be noticeably sharper. Also, even top-end tri/quad SLI systems tend to struggle with 4K with average games (not even cutting edge graphically), so unless you're using a 5K+ system I wouldn't recommend a 4K monitor at the moment.

According to this link, 4 titans put out 12k.

That was disappointing and a little bit misleading. I see "12K" and expect a single monitor with it. (I hate that we are calling it numberK)

But it's just three 4K monitors, which means it doesn't have the same effect.

Allright thanks,
I guess i'll be downsampling and see how that goes, or maybe get a 2560x1440 screen sometime. I don't have the money to buy another gpu to sli it , and the prices of 4k monitors are way beyond my budget. Anyway, now i know. Thanks

Downsampling is just another form of AA. It's better than raw 1080p but it's not the equal of 4K.

I am one of those who believes high resolutions are absolutely possible. I think for 4K you are going to want a 6GB card and probably SLI even for moderate gaming. At high rez you drop AA and don't really need it, but 4K is still not easy to push.

You're right to want more than 1080p. A 3GB 780 can certainly handle 1440p no problem, I'd advise a nice 1440p monitor. Alternately, get a 144Hz monitor to utilize excess framerate.
