High Definition (HD) and Extreme High Definition Gaming (XHD)
HD gaming: playing any of the 2008 Games for Windows titles with High quality settings at 1680x1050 (20 and 22-inch widescreen LCD monitor) or 1280x1024 (19-inch LCD monitor) resolution. A gaming system is not simply a desktop you play games on; it must be a properly-configured, well-tuned and rigorously tested machine. Since most gamers do not have thousands to drop on their setup, performance/dollar and energy-efficiency have to be a part of the equation as well.
HD Gaming
High-definition (HD) video generally refers to any video system of higher resolution than standard-definition (SD) video, most commonly at display resolutions of 1280×720 (720p) or 1920×1080 (1080i or 1080p) where i is for interlaced video and p is for progressive.

XHD Gaming
XHD Gaming
Extreme High Definition, or XHD, is a term coined by NVIDIA and Dell at the Consumer Electronics Show 2006 to emphasize gaming at resolutions, higher than High Definition. The term was created as a marketing term for NVIDIA's Quad SLI setup and Dell's 3007WFP monitor.
According to NVIDIA, XHD is achieved by using one or two dual-link DVI ports. This higher bandwidth allows the cards to reach a maximum resolution of 2560x1600. The resolutions 1920x1200 and 1680x1050 are also classed as XHD resolutions, even though they do not match the XHD specification of 4x1080i / 2x1080p stated on the XHD site.
To experience XHD, you need three supporting components – an NVIDIA GPU , an XHD monitor, and software that support XHD. XHD lets you spread your work over the entire desktop providing over 20% more desktop space than normal 4:3 aspect ratio monitors. At XHD screen resolutions of 1680x1050 and 1920x1200, games have up to 65% more image detail than games viewed on common 1024x768 notebook screens.
