Issue in installing the mod into razreshenii 1K or 2K (The Elder Scrolls 5: Skyrim)

I'm interested in the mod Skyrim HD - 2K Textures www.nexusmods.com/skyrim/mods/607?tab=files

There is an option in 2K it's actually 1.8 GB, and weighs a smaller version in the 1K and weighs in at 530 MB. Since I have a laptop with a resolution of 1366x768 I downloaded the smaller version and installed it, was guided by the fact that shake even a larger resolution than can afford my laptop, but the image is not liked, on the website the screenshots look much better, that is my laptop on the website shows more beautiful picture. The issue is that if I downloaded the full version in 2K whether it's higher quality? The question is asked because the ' net is slow, well put and delete is also not desirable because there are other mods that conflict.
