Some noob wishes that need to be addressed in terms of the real world:
Wireless transmission of video to a TV from a PC is difficult.
People throw around networking wi-fi terms and thinks it translates to A/V easily, but it truthfully is not simple at all. Audio and video, unless it is compressed, is a TON of data. When you get cable TV at home that is a compressed signal, but what comes out of your laptop, or out of a DVD player or cable box is uncompressed video. It is on a magnitude which is easily 10 times or more of the compressed signal that was originally sent.
To give you a comparison, a home network has some difficulty keeping up with two or three compressed HD streams across a wired network. One uncomprssed stream will typically be more than a home network can handle.
So, you can compress the signal and send it, but you get something similar to what you are currently seeing -which is most often very poor video quality.
The solution for wireless video transmission? They now have wireless HDMI transmitters/receivers which can transmit uncompressed HDMI about 20' or so. They run $200 or more pretty easily.
Alright, second thing I've noticed in your responses...
You need to understand what the different video connectors are and their quality and resolution capabilities.
Video: Standard broadcast television resolutions are 480i, 480p, 720p, 1080i, 1080p/24, and 1080p/60. It is worth reading Wikipedia about what those five resolutions mean, but the general breakdown is:
480i = 720x480 broken into halves
480p = 720x480 sent as a whole
720p = 1280x720 sent as a whole
1080i = 1920x1080 broken into halves
1080p/60 = 1920x1080 sent as a whole, 60 frames per second (high end video/PCs)
1080p/24 = 1920x1080 sent as a whole, 24 frames per second (movies)
Composite (yellow RCA connection) - This is the bottom of the line. It carries standard 480i video. It can NOT output any resolution higher than 480i.
S-Video (funky round 4-pin connection) - A quarter of a step up from composite and rarely looks better than composite. Still can't go higher than 480i.
Component video (red, green, blue RCA connections) - Can carry resolutions higher than 480i! This most often is 480p, 720p, and 1080i. It can carry 1080p, but rarely does so.
VGA/RGB - These are computer standard video connections using a 15-pin connector or five wire connection. It can carry standard video resolutions, but most often is carrying computer resolutions like 1024x768 (XGA) or 1366x768 (WXGA), or some other standard PC/VESA resolution. Note: VESA is a standards group often associated with PC standards, it does not directly tie into NTSC/ATSC standards which control video standards and their resolutions!
HDMI - This is what I consider one of the gold standards for connections these days. It carries all video resolutions up to, and beyond 1080p video including newer 3D standards. It also can carry audio on the same connection. If you have a laptop with a HDMI connection you can typically get 1080p resolution off that connection WITH audio right on it! A direct connection from your PC to a receiver or TV will deliver audio and video. Note: HDMI's audio connection can carry HD audio which can be identical to what a studio album or movie is mastered from! Best audio and best video in one.
DVI - Older digital connection similar to HDMI and orignally pushed by PC manufacturers as a digital standard. Not used nearly as much but still definitely out there. No audio on this, but high quality digital video in all formats possible.
There are a lot of other connections out there, but those are really the most common. DisplayPort is being pushed off by some PC manufacturers as 'the future', but seems to be a direct competitor to HDMI without any obvious advantages.
HD-BaseT (
HDBaseT) is by far the most exciting new connection IMO. It carries HD audio, HD video, 3D video, and ethernet, and MORE all over a single CAT5 or CAT6 cable over 300 feet. Cheap cable, small simple connection. It is NOT a network standard, but uses standard cheap, reliable cable.
As for speakers, it is better to buy good speakers and pair them up with a good receiver and buy quality first. You already have cheap and entry level, so start saving up for quality and get it into the mix.
