1080p on a 4k 15in?

Hi everyone, I'm planning to buy the new XPS 15, and though I don't wanna buy it because of gaming, I'd like to do a little bit of gaming on the side. However, it's quite obvious that a 1050 can't run modern games in 4k. I'm wondering if anyone has had some experience with playing on 1080p on a 4k laptop.

Thanks in advance

funnily enough i was looking at this exact laptop earlier today, and asked myself the obvious question, why on earth have they stuck a 1050ti to a UHD panel ? as for the scaling question though, 1080p scales better to UHD than it does to 1440p, because it's whole integer divisible, whereas 1440p is not. (1440p is 1.5 times the res of 1080p leading to scaling artefacts whereas 2160p is precisely 4 times the number of pixels meaning a simple 1:4 scaling can be done)

I have the same concerns about the XPS 15 and I hesitate between the UHD or FHD screen. I guess I'll go for the QHD to not loose in screen quality from my macbook, but I also want to see 1080p upscaled gaming to see if it's noticeable. (I sometimes game on my Macbook in half-Retina resolution (1400x900px) and I barely notice the upscaling, but I play on the lowest settings possible as the Macbook Pro Retina gets insanely hot).

 

Also Nvidia has a technology to handle upscaling with the GPU (Dynamic Super Resolution - http://www.geforce.com/hardware/technology/dsr) so I guess it'll improve the upscaling without loosing too much performance.

What I would like to see is UHD/FHD comparison screenshots between no upscaling, native upscaling and DSR upscaling. Is there any way to get that?

The difference would effectively be 1080p vs 4K vs 4K (rendered down to 1080p). 

1080p from 4K looks much better than native 1080p but whether its worth the difference is for you to decide. Bear in mind this is comparing max settings at both resolutions so a 1050 couldn't push that at upscaled 4K or natively.

 

Screenshots were taken with FRAPs in game in JC3
