neural, cancel your cable. It's okay...
I have my computer hooked up to a projector.
E obrigada, é claro que esse lugar não é o mesmo sem mim, né? rsrs
I'm sure I was terribly missed.

Unveiling The Sixth Sense - TED Talk

dan00108 says...

Do you guys really consider this to be a sixth sense device? It looks to me like a projector, cellphone and camera strapped together around your neck. And walking around making weird gestures are in the same category to me as talking to a bluetooth wireless headset, and could probably get you killed.

Help me with my purchase of an HDTV, please (1sttube Talk Post)

spawnflagger says...

KP, I have seen a TV from HP and 1 other brand that have built-in streaming features, but the unit was much more expensive than just buying an HDTV + game console (or that Roku player), so I would find a TV you like first.

Some other points related to some comments above:
1080p- a few years ago this cost a lot more, but nowadays it's only marginally more expensive than a 720p, many blu-ray discs are encoded 1080p, so it's worth getting a 1080p screen today. (I have a 720p LCD TV that I bought 2 years ago, and it's fine, though I use it mostly for games).
^MycroftHomlz, p (progressive vertical lines) is not dpi (dots per inch) (a 46" 720 dpi display would cost over a million dollars and have 225 times the resolution of 1080p)

120Hz- this is the new fancy feature on higher-end hdtv's. it doesn't magically make your content any better. Even the best Bluray movies are still recorded and encoded at 30fps. It will make some DVD content look better, because 120 is an even multiple of 24, whereas to display 24fps content at 60Hz (standard refresh rate of LCD's) you have to drop or add frames (called inverse-telecine) so sometimes you see tearing. So movies, sports, games, with lots of motion or many small moving details will look better. I've asked several Best Buy "tv specialists" some specific questions about 120Hz that I already knew the answers to, and NONE of them got it right. and instead of just saying "I don't know" they talked out of their ass and tried to sell me some special hdmi cable that supports 120Hz... epic lolz. If your total budget is $1500, don't waste your money on this feature.

LCD vs Plasma vs DLP- The quality depends a lot on the manufacturer. It used to be that LCD screens simply could not be made as big as plasma, but they are getting larger and cheaper each year. Plasmas still have burn-in problems (more problem for games than movies), and a shorter life span (about 7 years vs 10+ years for LCD- both assuming you use the TV several hours per day). Plasmas are also more fragile, so be careful when moving them. That said, I think the picture does look slightly better on plasma, but would still get LCD. (samsung, sony, mitsubishi- all great choices. other brands, try to look at it in person before you decide). DLP is a rear-projection TV, and I've found these to not be as crisp as LCD/plasma (sometimes the pixels blur and/or you can see horizontal scan lines). They are usually 80+ lbs vs an LCD being 30 lbs (base detached). Some people can see a flickering of the color-wheel with DLP (personally I can't, depends on lighting conditions and how sensitive your eyes are).

streaming content- if you have a PC with windows XP media center or Vista premium/ultimate, and all your content is windows compatible, an xbox-360 will make a nice front-end that you stream videos from your PC. If you use other formats, the PS3 has a better chance of playing them (also recommended since it plays bluray). I have both consoles, and the PS3 is much better at playing H.264 videos from CD-R/DVD-R and wired network. I haven't seen Roku player in person, and I don't have netflix, but it looks like a nifty device. If you subscribe to cable or fios, many of their DVR's can stream content that was recorded in other rooms.

projectors- not sure if you will find a decent 1080p one under $1500, but you can get a very large screen. Keep in mind the cost of replacing the lamp/bulb can be several hundred $$ (lamps usually last 2000+ hours in eco-mode). I have a 480p (widescreen but not high def) projector in my bedroom with an 8' diagonal screensize. Upon advice from someone else, I bought a 4'x8' foam board, and painted it with brightest white but non-glossy paint, and hung it on a wall for my screen. $380 projector + $30 screen + $37 progressive DVD player + $15 component cable + $30 black curtains. Compgeeks has a electric roll-up screen for pretty cheap.
Choosing a projector also depends on your room size, visit www.projectorcentral.com and use their calculator for any given model you are considering.

cables- buy online. someone mentioned monoprice, they are good, just check their in-stock status to be sure. they always ship ground from CA, so can be slow depending on where you live. HDMI and DVI are electrically identical, so it's a passive adapter. HDMI includes extra pair for sending digital audio. Component and VGA are analog, HDMI/DVI is digital - means more accurate colors, less ghosting/interference effects. Although analog is capable of carrying a full 1080p signal, content creators (namely Sony blu-ray) will cripple devices stating that you need HDMI to do 1080p output. This is because HDMI support encryption in the form of HDCP, which they think will reduce piracy (obviously they have been proven wrong already). fiber (sometimes called TOSlink) vs digital audio over copper (RCA jack) doesn't make a difference in quality, digital is digital. Look for a stereo receiver with many inputs and outputs.

antennas- hdtv's can pick up all the local broadcast channels with perfect picture and digital surround sound, if you get the right antenna. check www.antennaweb.org to see where channels are broadcasting relative to your home and to pick the correct antenna. It's a 1-time fee, unlike month-to-month cable/satellite. www.titantv.com is a tv-guide style website, lets you sort by broadcast type.

internet speed- 1.5Mbps should be fine, as long as you have patience to download the video before watching it. Will stream standard def no problem, but high-def or netflix downloads would take longer-than-realtime. Most services let you download in advance, so I wouldn't upgrade your 'net connection until you try it out for a month or 2.

buying online- go to best buy or walmart, and look for a screen you like, so you can see it in person. a lot of times the specs "on paper" look good, but the display is mediocre at best. Then look for exact model online, try to get a pricematch. Get the extended warranty if it's not outrageous (a single repair could be $500+ without it). We bought a 46" LCD for work from www.lcdtvs.com, they are New Jersey based, and their salespeople might try to up-sell you some cables, but we got free shipping and a free hdmi cable from them, and 3rd-party warranty was cheap (service is actually provided by best buy locally). Took about a week to arrive (western PA). If you buy online, make sure you factor in shipping costs, it could be $150+ since it's considered freight.

wireless vs wired- Roku, Wii, PS3 have wifi built in. xbox-360 is $99 for the wifi adapter (all except wii have wired ethernet built in). It's not too hard to run cat-5 cable if you are a DIY'er, but would be really expensive to get an electrician to do it. Ethernet hubs/switches are cheap, put a 4-port hub at your TV, run single cable between hub and DSL/cable/fios router, and all devices are online.

hope that helps. sorry for the long post. I'll answer specific questions if you have any.

An Expensive Game of Bowling

NordlichReiter says...

the wrist strap sucks, its a thin piece of crap.

I'm not an ass, but I do have a an old camera strap that I use when playing Wii sports.

I was under the impression that playing video games on a plasma was not a good thing.

LCD is fine for video games, but plasma is not. Its like a projector TV. Even only an hours play could cause a burn, heh in some TVs an hour of watching the CNN can cause a burn on he bottom of the screen from the marquee.

European Sulphur Plasma Light 1300W+

Croccydile says...

I remember reading about this in a magazine a good time ago, glad to see that its finally a reality.

Farhad you pretty much described my situation, I think I'm lacking in decent sunshine as well from the harsh florescent lighting here.

The video likely does not convey how brilliantly bright this is. Guessing from existing HID lamps, at 1300W this thing must be able to light a huge space by itself.

Or a better analogy, the HID lamp in even a quality high end LCD/DLP projector is at most 300-400W.

kagenin says...

I got two words for the AVGN: Matrix Switch.

I <3 my Matrix switch. My TV only has one HD input, but I got a PS2, a Wii, and my PC to hook up to it. My matrix switch has 4 inputs, and 2 outputs, so if I ever get a projector (its in the plans ), I can use that to let my girlfriend watch a movie on my PS2 in prog-scan goodness, while I play with my Wii on my TV. Once I got the cash for either a PS3 or 360 (haven't decided which yet, too broke for either now), I'll have a spare set of component inputs.

Oh god back to the pork-barrel ear marks. Projector for a planetarium sounds like a good earmark to me.


Neocons always bring up things like that as "big spending", but they never complain about the trillions their party spends on terrible foreign quagmires.
