They do put G-sync in the LCD displays of laptops and you don't necessarily need an external monitor. It is a relatively recent update that started with the G751 and continues in the G752 series. However, there is a certain price point that it is included and is usually around $1400. That is why I'm looking into this laptop because that is an excellent price point to get a G-Sync compatible LCD. Looking at Asus's website, they do not advertise the G751JL as having G-sync as opposed to the ROG G751JT/JY models. So, if you are not seeing anything obvious to turn on G-sync using the laptop display only, it looks like I'm out of luck on this model. Thank you for checking. 上面是 你这款美亚机器,的用户的答复,因为有人提出怀疑了,说不带G-Sync。 另一个 965m的评论 I believe you are correct. I checked the nvidia control panel and the option to enable G-sync is not there. To be honest, I have had no stuttering or visual issues with this display. The color and clarity is excellent. Update: I have been told that the 17.3" screen is not G-Sync compatible. FYI, HWiNFO shows the panel is a LG Phillips LP173WF4-SPD1.
