Video Walls

June 14, 2013

video walls

As flatpanels have been coming down in price, videowalls have become a popular method for advertising and displaying content in a larger format.  Video walls are often found in entrances, windows, control rooms, stadiums, and other large public venues, such as baggage claims. They can also benefit smaller venues when patrons may view the screens both up close and at a distance, respectively necessitating both high pixel density and large size.

A video wall consists of multiple displays tiled together contiguously or overlapped in order to form one large screen. Typical display technologies are usually LCD, LED, or plasma screens. Reasons for using a video wall instead of a single large screen can include the ability to customize tile layouts, greater screen area, and greater pixel density.

Screens specifically designed for use in video walls usually have narrow bezels in order to minimize the gap between displays – and are made to be left on for longer periods of time. These displays usually come with menu features made for video walls; A command signal may, for example, power all screens in the video wall on or off.

Simple video walls can be driven from multi-monitor video cards, however more complex arrangements may require specialized video processors, specifically designed to manage large video walls.  As always, we can accompany this technology with a wireless touchpanel or Ipad to facilitate operation and create a simple interface.  If you are looking for way to wow your audience, video walls may be the solution for you.

Latest on Projectors, Plasmas, LCD/LED TVs

March 16, 2013

Quixel Research has provided this year many reports on the consumer audio and video state. Here are some highlights on front projectors, LCD/LED TVs and plasma TVs.

Low-resolution Video Projectors Drive the Category

Front projectors grew in 2012 with unit sales by nearly 160,000 versus the previous year, but revenues minimized by 8% over year-over-year. This category rose 30% in revenues and 24% in units from Q3 to Q4 2012. Value-priced 720p projectors got in both revenue and unit share in this overall market.

LCD/LED displays over 50-inch fuel big-screen category

LCD/LED TV was up in unit sales by 2% in 2012 compared to 2011. The fourth quarter was up 29% in whopping versus the third quarter. Revenues declined by 3% in 2012 versus the previous year. TVs larger than 50-inch grew in unit share from Q4 2011 to Q4 2012from 11% to 24%. The top selling LCD TV was a 60-inch model for Q4 2012.

Plasmas Still Alive

The plasma segment unit sales grew about 70% in 2012 versus the previous year for TVs larger than 60-inch. Revenues maximized 53% in 2012 to a total of about $800 million for the year. Category of plasma TV is still so much alive, especially with its well-priced 50-inch and 60-inch 1080p models.

Plasma TV altitude: What height can they go?

March 13, 2013

Plasma TVs don’t handle well high altitudes because of how they work, but what height is very high? Plasmas generate light with buckets of tiny pixel-size lined with a phosphor material. A noble gas, like argon, is filled in these buckets and sparked into a plasma by Electrodes that emits UV light then makes the phosphor flash a specific colour. The gas pressure and the panel structure/glass strength are balanced at sea level versus the external air pressure.

Plasma TV altitude

There is less pressure and the air becomes thinner as going toward space. Since plasma TV is sealed, the noble gas spreads, pushing the glass apart very slightly. As such, it gets it a bit harder for any electrode mounted on front of the glass for doing their electro-magic. They and the glass do a bit extra noise as they work harder. Plasma TV has gotten a so better, its glass has become stronger, and designs have gotten more sturdy, so this is so less of issues than it once get.

This means that: Denver is about 5,400 feet thus that is fine. Santa Fe is about 7,200, right on the Panasonic and Samsung cusp, but good for LG. People in regions like La Ronconada, Peru (16,728ft), Breckenridge (9,600ft), or La Paz (11,942ft) might should to consider LCDs.

Panasonic: Plasma is still the best TV technology

March 12, 2013

If you are purchasing a new TV and look for the best picture quality, plasma TV is still absolutely the best one to get. It isn’t like LED that is bright and more in the face, which many people like. But it’s a various appreciation kind for the TV experience with plasma TV. So it is still the best tech for movie and sports.

Panasonic plasma TV

Unlike plasma TV that uses glass panels with over two million of tiny cells filled with inert gases mixture, LCD TV uses a LEDs array for illuminating their pixels. The gases are excited when an electric current passes through these cells, causing them illuminating the pixels over the screen. This lighting method is better for contrast levels, motion reproduction and reducing 3D crosstalk than LCDs.

Panasonic is today the only leading brand producing full plasma TVs ranges, and though the undisputed plasma king (Pioneer) couldn’t get the tech pay financially. Panasonic thinks plasma is only now as a display technology coming of age. The nice thing is that it is now where we have the right balance, where anyone has got the best quality of picture at a lot more affordable price.

Elite TVs- When you want the best

February 7, 2012

elite tvs

 

A lot of excitement has been generated recently with the return of the Elite brand.  Pioneer Elite is well-known to be the best of the best when it comes to picture quality.  Well, until Pioneer decided to up and leave the Plasma market.  It was long rumored that most of the techs from Pioneer joined Panasonic and that Panasonic may bring the Elite name back, but Sharp recently acquired a controlling interest in the Elite brand and has officially released the new Elite lineup.  This lineup consists of the two largest 3D-capable HDTVs today, the 60” PRO-60X5FD, and the 70” PRO-70X5FD.

The picture of the Sharp Elite PRO Series HDTVs delivers deeper black levels and better contrast than any other LCD or plasma on the market. Unlike other full-array local dimming TVs, it maintains its superior picture from normal viewing angles and blooming artifacts are virtually nonexistent. Color is extremely accurate, shadow detail is excellent and video processing does everything we expect and more. The screen maintains black levels well under ambient light.  Like all newer premium TVs, they’re 3D-capable and have internet connectivity. They have built-in Wi-Fi, and a suite of internet services that includes Netflix, YouTube, Napster, and Elite Advantage, a concierge service that provides owners with remote assistance and diagnostics. No-nonsense styling, best-ever energy efficiency and a nearly-complete feature set, including two pairs of 3D glasses, ice the cake tastefully.

The Elite Series HDTVs may cost more than your standard HDTV, but there is good reason.  Everything about them, such as their picture quality, their support, and their looks is a level above the competition.

The 3D Phenomenon

February 16, 2011

If there is one thing that was made abundantly clear at the Consumer Electronics Show (CES) in Las Vegas last year, it was that the entire consumer electronics industry was strongly pushing for a switch to 3D. Sony, Panasonic, Samsung, Toshiba, Mitsubishi, Vizio, Sharp and a number of other manufacturers have all announced new 3D capable models that they will be releasing over the course of this year (2011). Never before have we seen such widespread industry support for 3D, and this will certainly go a long way in helping bring 3D to the masses.

Riding on the enormous success of James Cameron’s latest movie, Avatar, many of the big name electronics manufacturers are making a strong case for bringing an authentic 3D experience to the consumer’s living room. This time around the timing seems perfect. Over 60% of Avatar’s ticket sales were for 3D viewings of the movie, a startling statistic given that the number of 3D capable screens around the world is far outnumbered by their regular 2D counterparts.

New 3D technology overcomes previous limitations

Old 3D technology from many years ago never really caught on, but new 3D technology overcomes its previous limitations.

  1. Unrealistic to Realistic 3D – An unrealistic effect was caused due to the images for the left and right eye being unnaturally spaced causing eye strain. However, current 3D video capture technology coupled with the projection of both left and right eye images by the same device ensures that such effects are mitigated in new 3D displays.
  2. Goodbye to Nausea and Headaches – These side effects were predominantly due to the analog nature of 3D films many years ago when the films for the left and right eye view were projected simultaneously but were hard to keep in sync with one another. This resulted in an uncomfortable viewing experience, confusing the viewer’s brain due to the unrealistic and unnatural visual stimulation.  Current 3D displays however, are digitally synced so no such issues exist and these “3D Symptoms” are thankfully a thing of the past.
  3. Poor to Great color fidelity – Using Anaglyph technology, images were split into chromatically opposite colors so that by using tinted glasses the viewer was able to view a unique image for each eye thus providing a 3D effect. However, the use of these tinted glasses drastically changed the appearance of colors and in general resulted in a poor 3D experience. With the use of new Polarized or Active Shutter technology, this has been done away with as the image displayed on the screen represents the true color and each eye piece does not distort the image color in any way (apart from lowering the incoming brightness of the image by a small amount).

3D Content

Many people seem to whine about the lack of 3D content and that this lack of 3D content guarantees the failure of this industry push towards 3D. After all, content is king right? There are some issues with this criticism however.

  1. ESPN, DirectTV, Discovery Channel and UK’s Sky have pledged support for delivering 3D content as early as 2010. ESPN has already procured the necessary equipment for shooting live events in 3D and plan to air football and NBA in 3D in the near future. A number of other content providers are also joining ranks and pledging support for delivering more 3D content. While 3D content is still at a nascent stage, we have to keep in mind that these are still early days. However, with all the industry support so far, the signs seem very positive.

2.      Hollywood is also backing this push to 3D with over 20 3D movies released on 2010. Keep in mind also that every 3D animated film will likely be available in 3D as this medium enables an effortless transition for producing movies in 3D. These numbers will only increase, especially if there is widespread interest in 3D content as witnessed by the success of Avatar in 3D.

3D TVs are Backward Compatible with Regular 2D

This is one of the main reasons why 3D will eventually succeed over time. Pretty much all the proposed 3D technologies that are being developed by various electronics manufacturers are compatible with regular 2D content. This of course is for a good reason as it would be suicidal on the part of device manufacturers to make their 3D sets not compatible with conventional 2D content given that there is a long transition period ahead as we make the switch from 2D to 3D (and perhaps it will never be a complete 100% switch).

Displays requiring active shutter glasses are pretty much your regular high performance LCD or Plasma TV with a high refresh rate (120-240 Hz) and the ability to sync with your active shutter glasses. However, they are perfectly capable displays for 2D content as well and there shouldn’t be any real decrease in performance or image quality. Additionally, the high refresh rates of newer 3D TVs will actually be a bonus for regular 2D content as this refresh rate boost will help smooth the display of fast paced 2D scenes and sporting events. Finally, the prices of the TVs themselves aren’t going to be all that much more than regular TVs.  If you don’t want 3D at all, you could still buy a 3D capable set for roughly the same price as regular TVs and just skip buying 3D glasses and any other accessories that you might need for viewing 3D content on your new TV. All in all, it’s a win-win situation either way and this is one of the main reasons why the long run adoption of 3D TVs will hence in general a will win situation.

What Audio/Video Improvements Can Do For Your Organization

January 20, 2011

Audiovisual isn’t just slide shows on rickety projectors anymore.  The audio video industry, like everything else, has taken a gigantic leap into the technological future.  Audiovisual systems enable a business to get their message across more effectively, because in many cases, visual presentations of information are much more memorable

Your company likely doesn’t have anyone with expertise in audio video.  It’s not uncommon to see IT specialists called in to try to set up a firm’s audio video system just because they have a basic techie background.  But real audio video specialists are engineers who can design to your company’s exacting specifications.  They do everything from hanging a projector from the ceiling of your meeting room to installing a motorized screen that comes out of the wall to programming the software that facilitates it all.  Your conference room can be transformed into a state-of-the art think tank, with all the equipment controlled by a single remote.

Seventy-five percent of all projection systems sold are for PowerPoint presentations, but audio video services range from LCD projectors to interactive whiteboards to audio and video conferencing systems that enable your staff to exchange ideas from as far away as separate continents.  Technological advances have kept pace with those in consumer electronics, with wall-hanging plasma displays that can handle inputs from different sources, including DVD and computer sources.  With all these technologies, your meetings can include interactive video, striking graphical representations of any kind of data, and information that viewers can engage with in powerful ways, whether the context is an employee in-service training, consultations with business partners or proposals to prospective customers.

The key variables in selecting audio video services are centered around what your company is going to use them for. The initial meeting with is called a “needs assessment,” and based on the information you provide, services will be designed around that.  Are the majority of your presentations based on PowerPoint, videoconferencing or computer-based training?  The number of meetings you conduct, the size of the group, and what type of presentation you are conducting should all be taken into account.

LED Television Technology – Why Should you Buy an LED TV?

December 7, 2010

The Advantages of LED HDTVs

The LED-HDTV is the new option if you are looking to buy a new flat screen. Whereas before our choice was mainly limited to LCD and plasma TVs., now we have another contender to consider, the LED television. However, an LED screen will currently cost you more money than a standard LCD or plasma TV, so we need to understand why we might think about buying one of these televisions.


Here are a few reasons of why it may be worth switching to an LED television.

1. Brightness

LED lights are brighter than a fluorescent lamp, and so you should expect to get a brighter picture with an LED television compared to a standard LCD.

This should be especially useful in bright rooms with plenty of daylight, as the image should stand out much better.

A non-reflective screen, together with a brighter image, could make this a perfect choice for some rooms where the reflection of daylight could be a problem.

2. Picture Quality

The excellent picture quality is where a backlit LED HDTV comes into its own.

If you want to have a picture quality that is similar to that of a plasma screen, but wish to stick with LCD screen technology, then a backlit LED HDTV is worth considering.

An LED TV that is backlit, with local dimming and RGB LEDs, should have a much improved picture over that of a standard LCD TV.

You should expect to see a better contrast ratio and color accuracy.

3. Great Looks and Easy Installation

The new edge-lit LED HDTVs look fantastic.

They are thin, sleek and very modern-looking – so they will be a breeze to hang on the wall or stand elegantly in the corner of the room.

If you want to impress your neighbors, then just install one of these beauties in your room.

This might be reason enough to switch to an LED HDTV.

4. Low Power Consumption

The power consumption of LED HDTVs does vary between models.

So if you were thinking of buying an LED screen to save on power, it is wise to check with each particular model.

However, an edge-lit LED television can consume 30-40% less power than any other type of LCD or plasma TV.

Be more careful with backlit LEDs. They can actually be more power hungry than standard LCDs – and can be similar to that of a plasma screen. However, it is difficult to generalize about this issue as using different types of LEDs can also make a difference.

Backlit models which use RGB LEDs are often more power hungry than those that just use white LEDs – so if power saving is an issue for you, then check out an edge-lit LED television.

LED Television Technology Summary

So are the benefits of LED HDTV technology worth it to spending a bit extra?

No technology is perfect, and so there is always a need to weigh up the pros and cons of any TV before you buy one.

While these TVs are currently more expensive than plasmas or standard LCD TVs, there are reasons why it may be worth the extra money.

An LED screen can offer looks, ease of installation, low power consumption and an improved picture over other types of television – so decide how important these features are to you.

Plasma vs LCD

September 27, 2009

Having trouble deciding between plasma and LCD televisions? You’re not the only one. The truth is you are not going to go wrong with either. Each technology still gives you a far greater picture than any analog TV, and with the widescreen image you get to see more information.

In general LCD TVs are best for more well lit rooms, however, Plasma TVs give a better image when you have solid light control.
If you tend to watch your TV a lot during the day then we recommend LCD TVs. If most of your TV watching is in the evenings, then we would recommend Plasma technology. Plasma TVs will give typically give you a sharper image but because of their reflective glass, it really depends on your viewing times.

On the other hand LCD TVs are best for playing video games, or for hooking up to PCs, as they less likely to suffer “burn-in”, which can be caused by having static images on the screen for too long. Plasma TVs, however, are best for watching movies and sports.

The key thing is that you are living in high definition, but, to help you out we’ve got this handy chart to help you determine which technology is best for you.

Plasma LCD
