A:AnswerAlienware is only 1080p. Samsung has better graphics. Alienware 240 FPS at 1080p. Samsung 144 FPS at 1440 pixels higher then 1080p. Samsung has better graphics with less FPS it’s still the better choice in my opinion. I have the Samsung 32 inch not the 27 inch. If you have a strong rig that can use the 240 FPS and if your fine playing 1080p then get Alienware. But I bought the Samsung 32 and I have no regrets.
A:AnswerI can confirm I get 144hz at 2k while gaming. I am currently running this monitor on a 1080ti. That said, I know software exists to enable freesync on g-sync devices. I have not looked into trying it just yet.
