Why can't the PC do HD gaming?

[The Anarchyz]

Good one, especially being a copy of another thread in other forums... But just for the people that don't know about this, i'm gonna explain it:

PC doesn't do HD because that's a TV marketing decision, analog TVs had the NTSC/PAL standard definition for a long time before the digital signal hitted the TV world (late 90's), then, with digital capabilities, the TVs could do better resolutions, so they agreed to some resolutions (1280x720, 1920x1080) and marketed as HDTV (High Definition Television)...

A PC monitor (always digital) evolved fast from the small monochromes to the resolution of 640x480 (VGA), then it went to 800x600 (SVGA), 1024x768 (XGA), etc., and the bigger the monitor gets, the more resolution it can handle (as long as the video card also can handle it), so PCs had 1280x720, 1920x1080, etc., wayyy before the TVs could do that...

The reason now video cards and monitors are being sold with the "HD" in the specs is because a lot of PC users don't know about PC resolutions, but they know about HD, so it's another marketing decision...

How you can hook-up your PC to your TV?

Analog TV: Look if your Video Card has a S-Video or Composite (Standard RCA Audio/Video) exit, connect the cables to your tv, configure the video and you're set...
Digital TV (Especially HDTVs): HDTVs have a Standard D-Sub (VGA) input, and a DVI/HDMI input, and video cards have also this exits, now you have to choose between those ones, connect the cables, configure the 2nd monitor and you're ready, but if you want to connect DVI to HDMI, you have to get an adapter, the video card can come with it, or you can buy it, it's cheap...
