Technology Untangled: Intel WiDi laptops provide wireless HDTV display

technology-bourIntel Wireless Display Technology, WiDi (pronounced why-die), is the clever extra feature that may already be on your latest computer. If you are shopping for a new model, it is a feature worth seeking out because it can simplify the process of connecting your laptop computer to a bigger display for court or for a boardroom presentation. This article will look at a simple-to-use technology that allows you to wirelessly connect to a big-screen high-definition television.

Typically, the best method to present your computer screen on an HDTV has been with a VGA-type computer monitor cable. Virtually all HDTVs have a monitor port like this (also often labeled as RGB). For a courtroom setting, that usually requires a long VGA cable, and a long audio cable for full multimedia capability. Most laptops now come with an HDMI output port allowing transmission of high-definition video and audio to an HDTV. While HDMI has made connecting simpler, it still requires a long cable running across the room.

WiDi allows you to cut the cable and present high-definition 1080p video to a large screen HDTV without being limited by the length of your HDMI cable. This technology uses a WiFi signal, so you can expect a wireless range similar to that of a typical WiFi Internet link.

This technology is ideal for users who have wide-ranging multimedia collections stored on their home computers. Sharing photos, videos and music with others can get a bit cramped when everyone is crowded around a 15-inch laptop screen. But this technology is a great way to present PowerPoint slides, deposition videos and legal documents on the existing HDTV screens that have become common in law firms and are becoming more common in many courtrooms.

Intel essentially incorporated a wireless transmitter in many of its laptops that use its 2nd Generation Core i3/i5/i7 processors with Intel HD graphics (in my case the processor is an Intel Core i7-2670QM quad core). This wireless transmitting technology has been built into many new laptops for about the last year, and it seems that more models have been coming out with this feature. To determine if your computer already has it, click on the “Start” icon on the lower left of your screen and type “WiDi” in the search window. See if WiDi shows in the “programs” list and launch from there.

If shopping, you have to read pretty far down into the specification sheet of any computer you are considering. Even if a computer has an Intel 2nd Generation Core processor, the WiDi feature may not be included since not all computer models are configured to take advantage of it. Sometimes you might see an extra sticker on the palm rest area of a new computer that says “Intel WiDi Wireless Display.”

While the transmitter is already built in, you still need a separate receiver that plugs into the HDTV ($79-$99). Two of the best are the Belkin Screencast TV Adapter and the Netgear PUSH2TV HD Adapter.

I found the setup of the Belkin Screencast refreshingly uncomplicated. I simply connected the HDMI and power cables, followed a few simple on-screen instructions and was up and running. I had to make only one adjustment, increasing the image size to eliminate black bars from around the edges of the screen. These receivers also have standard resolution jacks (video/yellow) and (audio/red and white) to allow connectivity to older TVs. These jacks could also be used to connect an LCD projector. You won’t have the stunning resolution of HDTV, but you will still be able to run your laptop wirelessly.

One security question answered itself as I prepared the receiver. A unique code is displayed on the TV that must be typed in on your laptop to couple the transmitter and receiver. This prevents you from accidentally beaming your exhibits to the courtroom next door. You can choose between duplicate display or extended display by pressing the Windows + P keys (the Windows symbol key is on the bottom left row). I like extended display because it allows you, for example, to play a video on the big screen and simultaneously sort through your exhibit spreadsheet during a trial. You can also use Windows + P to blank the TV display or the laptop display.

If you are in the market for a new laptop, shopping for models with Intel Wireless Display Technology could help narrow your search. WiDi is a feature that doesn’t seem to cost much more, but it does substantially increase the utility value of a computer if you think you will ever need to make presentations with it.•

  1. I have been on this program while on parole from 2011-2013. No person should be forced mentally to share private details of their personal life with total strangers. Also giving permission for a mental therapist to report to your parole agent that your not participating in group therapy because you don't have the financial mean to be in the group therapy. I was personally singled out and sent back three times for not having money and also sent back within the six month when you aren't to be sent according to state law. I will work to het this INSOMM's removed from this state. I also had twelve or thirteen parole agents with a fifteen month period. Thanks for your time.

  2. Our nation produces very few jurists of the caliber of Justice DOUGLAS and his peers these days. Here is that great civil libertarian, who recognized government as both a blessing and, when corrupted by ideological interests, a curse: "Once the investigator has only the conscience of government as a guide, the conscience can become ‘ravenous,’ as Cromwell, bent on destroying Thomas More, said in Bolt, A Man For All Seasons (1960), p. 120. The First Amendment mirrors many episodes where men, harried and harassed by government, sought refuge in their conscience, as these lines of Thomas More show: ‘MORE: And when we stand before God, and you are sent to Paradise for doing according to your conscience, *575 and I am damned for not doing according to mine, will you come with me, for fellowship? ‘CRANMER: So those of us whose names are there are damned, Sir Thomas? ‘MORE: I don't know, Your Grace. I have no window to look into another man's conscience. I condemn no one. ‘CRANMER: Then the matter is capable of question? ‘MORE: Certainly. ‘CRANMER: But that you owe obedience to your King is not capable of question. So weigh a doubt against a certainty—and sign. ‘MORE: Some men think the Earth is round, others think it flat; it is a matter capable of question. But if it is flat, will the King's command make it round? And if it is round, will the King's command flatten it? No, I will not sign.’ Id., pp. 132—133. DOUGLAS THEN WROTE: Where government is the Big Brother,11 privacy gives way to surveillance. **909 But our commitment is otherwise. *576 By the First Amendment we have staked our security on freedom to promote a multiplicity of ideas, to associate at will with kindred spirits, and to defy governmental intrusion into these precincts" Gibson v. Florida Legislative Investigation Comm., 372 U.S. 539, 574-76, 83 S. Ct. 889, 908-09, 9 L. Ed. 2d 929 (1963) Mr. Justice DOUGLAS, concurring. I write: Happy Memorial Day to all -- God please bless our fallen who lived and died to preserve constitutional governance in our wonderful series of Republics. And God open the eyes of those government officials who denounce the constitutions of these Republics by arbitrary actions arising out capricious motives.

  3. From back in the day before secularism got a stranglehold on Hoosier jurists comes this great excerpt via Indiana federal court judge Allan Sharp, dedicated to those many Indiana government attorneys (with whom I have dealt) who count the law as a mere tool, an optional tool that is not to be used when political correctness compels a more acceptable result than merely following the path that the law directs: ALLEN SHARP, District Judge. I. In a scene following a visit by Henry VIII to the home of Sir Thomas More, playwriter Robert Bolt puts the following words into the mouths of his characters: Margaret: Father, that man's bad. MORE: There is no law against that. ROPER: There is! God's law! MORE: Then God can arrest him. ROPER: Sophistication upon sophistication! MORE: No, sheer simplicity. The law, Roper, the law. I know what's legal not what's right. And I'll stick to what's legal. ROPER: Then you set man's law above God's! MORE: No, far below; but let me draw your attention to a fact I'm not God. The currents and eddies of right and wrong, which you find such plain sailing, I can't navigate. I'm no voyager. But in the thickets of law, oh, there I'm a forester. I doubt if there's a man alive who could follow me there, thank God... ALICE: (Exasperated, pointing after Rich) While you talk, he's gone! MORE: And go he should, if he was the Devil himself, until he broke the law! ROPER: So now you'd give the Devil benefit of law! MORE: Yes. What would you do? Cut a great road through the law to get after the Devil? ROPER: I'd cut down every law in England to do that! MORE: (Roused and excited) Oh? (Advances on Roper) And when the last law was down, and the Devil turned round on you where would you hide, Roper, the laws being flat? (He leaves *1257 him) This country's planted thick with laws from coast to coast man's laws, not God's and if you cut them down and you're just the man to do it d'you really think you would stand upright in the winds that would blow then? (Quietly) Yes, I'd give the Devil benefit of law, for my own safety's sake. ROPER: I have long suspected this; this is the golden calf; the law's your god. MORE: (Wearily) Oh, Roper, you're a fool, God's my god... (Rather bitterly) But I find him rather too (Very bitterly) subtle... I don't know where he is nor what he wants. ROPER: My God wants service, to the end and unremitting; nothing else! MORE: (Dryly) Are you sure that's God! He sounds like Moloch. But indeed it may be God And whoever hunts for me, Roper, God or Devil, will find me hiding in the thickets of the law! And I'll hide my daughter with me! Not hoist her up the mainmast of your seagoing principles! They put about too nimbly! (Exit More. They all look after him). Pgs. 65-67, A MAN FOR ALL SEASONS A Play in Two Acts, Robert Bolt, Random House, New York, 1960. Linley E. Pearson, Atty. Gen. of Indiana, Indianapolis, for defendants. Childs v. Duckworth, 509 F. Supp. 1254, 1256 (N.D. Ind. 1981) aff'd, 705 F.2d 915 (7th Cir. 1983)

  4. "Meanwhile small- and mid-size firms are getting squeezed and likely will not survive unless they become a boutique firm." I've been a business attorney in small, and now mid-size firm for over 30 years, and for over 30 years legal consultants have been preaching this exact same mantra of impending doom for small and mid-sized firms -- verbatim. This claim apparently helps them gin up merger opportunities from smaller firms who become convinced that they need to become larger overnight. The claim that large corporations are interested in cost-saving and efficiency has likewise been preached for decades, and is likewise bunk. If large corporations had any real interest in saving money they wouldn't use large law firms whose rates are substantially higher than those of high-quality mid-sized firms.

  5. The family is the foundation of all human government. That is the Grand Design. Modern governments throw off this Design and make bureaucratic war against the family, as does Hollywood and cultural elitists such as third wave feminists. Since WWII we have been on a ship of fools that way, with both the elite and government and their social engineering hacks relentlessly attacking the very foundation of social order. And their success? See it in the streets of Fergusson, on the food stamp doles (mostly broken families)and in the above article. Reject the Grand Design for true social function, enter the Glorious State to manage social dysfunction. Our Brave New World will be a prison camp, and we will welcome it as the only way to manage given the anarchy without it.
