I have a AMD 7870 Graphic card & intend to purchase Samsung S23A700D monitor to play 3D games. The problem is the CPU is about 5 meters further from the Monitor. My question is will i be able to play 3D games @ 1080p @ 120hz if i connect it through HDMI or use a DVI to HDMI connector ? I already have a premium 1.4HDMI cable and would want to know if i could get 3D working on it @ 1080p. Any help would be really appreciated.
No, at least not at 60hz. HDMI only supports up to 24hz (possibly 30hz with hack) at 1080p. It can support up to 720p at 60hz in 3D.
You'll have to use Dual-link DVI-D for 60hz at 1080p in 3D and 120hz in 2D. That is the only monitor I know of that supports dual link dvi-d with AMD, but it apparently works.
