The Lenovo Legion Y720...
According to this review (whose practice of charging for display profiles I disagree with, but I digress), the Lenovo Legion Y720 is using the LG LP156WF6-SPK3, a 45% NTSC color gamut panel more typical for the laptops in the $800-$1000 price bracket than laptops above it.
45% NTSC color gamut IPS displays may provide adequate contrast and viewing angles, but can visually fall short when it comes to color saturation. The majority of the competition uses 72% NTSC color gamut IPS FHD displays, which provide colors considerably closer to typical desktop monitors. Examples of $1300 GTX 1060 laptops with 72% NTSC color gamut IPS displays include:
- Acer Predator G9
- MSI GT62VR
- Acer Aspire V 15 Nitro, 3rd gen
- Eluktronics Clevo P650HP6 (I don't know if Sager uses 72% on the non-G-Sync models, which is why I didn't link them -- but the higher-priced G-Sync model I would expect to be 72% NTSC -- certainly for the offered 120Hz TN-WVA panel)
This link shows a comparison between a stock display and a user-upgraded display in Lenovo Thinkpad laptop, that can help to understand the issue.
This said, if you're in it for the 4K model instead, the good news is that it has been confirmed at CES to be using a true-4K non-PenTile display, which is a shining beacon of hope in a market saturated with PenTile not-true-4K-display laptops such as the MSI GS63VR and most Sager/Clevo 15.6" offerings. Thus my recommendations will likely end up being: Lenovo for 4K, the competition for FHD.
Final note: G-Sync and/or 120Hz would have been welcome offerings on this product line as well in my opinion, but sadly they are absent.
