...1366x768 resolution (1080i capable).
I'm not sure what they mean by "1080i capable" since 1080i means a resolution of 1920 x 1080i (a.k.a. HDTV). This particular TV is most likely classified as EDTV or Enhanced Definition TV.
As for which to choose, that depends on what's important to you. The Olevia has a larger display area, but it has lower resolution. I'm not a console gamer so I don't really know what resolutions those consoles are capable of.
If you need a monitor that can also double as a TV, then get the Olevia. If you want the graphics to look their best, then your best option is most likely the Samsung. If you just want a big screen and graphics quality is secondary then get the Olevia.
