4k resolution in 720p monitor

Do I need 4k monitor for 4k resolution in gaming
I am planning to buy GTX 1080ti and z270 motherboard but my monitor only has VGA port

There is a feature called "DSR" in the NVIDIA control panel that you can enable to achieve higher resolutions than your display can support.

I don't know if there is an option that brings 4K down to 720p.

RENDERING the game and DISPLAYING the content are two different things.

You can RENDER at 4K and downscale to a lower resolution, but that won't be true 4K.

You will mainly help eliminated jagged edges (anti-aliasing) but you won't have enough pixels on the screen to properly show textures or text optimally.

*And WHY oh WHY would you spend all that money on a gaming computer and use a crappy monitor?

your better off using AA than DSR. AA will be less GPU resource heavy then DSR 4k on a 720P monitor. You really should get a 1440P or better panel if you can afford it if your getting a gtx 1080ti. otherwise a simple GTX 1050Ti or GTX 1060 will be plenty at 720P.

This is true, but it is quite obvious that only 720p could actually be displayed on a 720p monitor.

I thought the question was about playing games at 4K on a 720p monitor (why someone would want to do that, I don't know, but that wasn't the question asked), not displaying a native 4K image on a 720p monitor.

Well since you have the budget for such high end components can't you grab a new 1440p or 4K monitor? 😛

If not as stated, just grab something like a RX 470 and max out 720p easy or for now as also mentioned you can use Nvidia DSR or AMD VSR (Same thing) to downscale to 720p, it but obviously not the full native image and yes AA is usually an easier and less taxing option.

Uh, no it's NOT clear at all.
You can RENDER a game at 4K, then DOWNSCALE it to 1366x768 which is completely different from rendering at 1366x768 and displaying at the same resolution.

Rendering at 4K is just as taxing as rendering at 4K for a 4K monitor. In fact, you add a small amount of extra work to downsample to 768p.

That is what DSR does in the NVidia Control Panel as said a few times.

And if you refer to my ENTIRE post it should be obvious what I was saying, especially the last line where I say ".. crappy monitor" so I thought it was pretty obvious that I was talking about rendering at 4K then downscaling to 720p (likely 768p really).

Anyway, the GTX1080Ti alone costs $700USD+ (too lazy to check exact) so you'd be far better off getting a weaker GPU and buy a good monitor (exact solution depends on total budget).

If it's not clear, here's the order of worst to best in terms of quality of image (not smoothness of gameplay), in fact it's mainly about smoothing the jagged edges more (i.e. anti-aliasing as 4K downscaling is basically supersampling. google is your friend):

1. 1366x768 rendered to 1366x768 monitor
2. 3840x2160 rendered to 1366x768 monitor
3. 3840x2160 rendered to 3840x2160 monitor

There are other issues as well such as HUD scaling that cause problems because if you tell the game to render at 4K you'll likely get small text/HUD elements that are not ideal for the number of pixels you have to work with.
