Lcd v’s Plasma here’s my 10 cents worth …
December 22, 2006 by Joe Boyle · Leave a Comment
I have a view that might suprise some readers of HTF as I think comparing [tag-tec]LCD[tag-tec] with [tag-tec]Plasma[/tag-tec] is like comparing different variations of fruit and trying to make out it’s a fair comparison.
Come on I for years watched my movies on a front projection 55 inch Toshiba but when compared with my 32 inch [tag-tec]CRT[/tag-tec] Toshiba the picture quality was light years away but guess which I enjoy watching the latest action DVD on?
Why we always seem to have to compare things in home theater is sometimes a mystery when we pick things which clearly are different and try to compare them you wouldn’t try and compare a Ferrari with Chrysler Neon would you …?
So coming back to my LCD vs Plasma and which is the right choice for your home theater set up ?
These two technologies are seriously different and not different sides of the same coin as some stores might have you believe.
Here’s the technical stuff Plasma Screen TV’s use charged cells of gas plasma to create a picture they are popular and range in sizes up to a massive 7 ft for standard TV use but I expect as I am writing this some one will be launching a bigger one.
LCD on the other hand were launched as the new flat screen technology and have been around a little longer earlier models had problems with lighting a bit like my old faithfull front screen projection TV but these problems have pretty much been solved.In case you were wondering LCD stands for Liquid Crystal Display but things have move on a significant amount from those first LCD calculators we first used nearly 25 years ago.
Viewing Problems with Plasma and LCD
The home theater purist believe plasma is the way to go if your budget allows for several reasons the most significant being the way black is viewed on plasma more effectively. This is primarily because an LCD uses backlight to display it’s images so there by it’s very nature has to be some excess light. New models have found ways around this problem and the top drawer compare well with plasma displays.
When it comes to image quality the LCD have it with a sharper image especially when watching action movies or action sports such as football or motor racing . In earlier models where objects move across a large block of solid color such as the quarterback throwing the football to the wide reciever or tiger hitting a golf ball up the fairway onto the green there were some problems but these are now rectified in new updates.
Budgets
Dollar for Dollar you get more screen display for your buck with Plasma providing you are looking for at least 40 inches or more. For smaller screens LCD is still cheaper and LCD technology is available for all budgets and all sizes at reasonable prices as technology has got cheaper as demand has increased. But if you want BIG go for plasma everytime.
Viewing Angles
Plasma screens have traditionally had better viewing angles than LCD screens although advances by LCD screen manufaturers have pretty much addressed this issue. Indeed many LCD screens are now better than the similar priced plasma models but at the high end plasma still rules the roost.
In my view you should check out all purchases yourself and draw your own conclusions and to help you I will be carrying out regular weekly reviews of different LCD and Plasma screens to help you make an informed choice…
In the meantime why not take some time this holiday season to check out some of the instore sets and decide which you prefer but remember you won’t be able to really appreciate these Tv’s unless you view them in your own home or home theater setup.
See you all soon

Why buy a video projector for your home theater system?
December 12, 2006 by Joe Boyle · Leave a Comment
Prices are crashing and with increased demand the cost of video projectors for home theater are set to drop even further.
The truth is there has never been a better time to consider buying a video [tag-tec]projector[/tag-tec] for your home cinema set up.
If you have just forked out for the latest amplifier and speaker set up and were looking forward to that ultimate movie experience and then felt robbed when the TV set just didn’t do it for you then you could be the ideal candidate for a home theater upgrade to a video projector either an [tag-tec]lcd[/tag-tec] projector or a [tag-tec]dlp projector[/tag-tec]
The harsh reality is if you have the space even a massive plasma screen can’t match he image of a projected image the size of the wall in your living room or den.
Over the last 2-3 years the technology behind video projectors for home theater has moved on by leaps and bounds which has lead to more and more people looking seriously at using a projector in their homes to create massive picture sizes for watching their movies , play video games and even enjoy their favorite sporting occasions.
Just imagine watching the Superbowl or the US Grand Prix life size ? Or maybe you could see yourself playing with your new wii - Got to be an experience to be lived in my book.
But the best thing about the projectors of today and the advances that have been made is that they are now with in reach of the average American home theater enthusiast and no longer the preserve of those that have six figure bank balances.
Of course with this increase in quality and reduction in price the video projector is now also increasingly also turning up in the boardroom of even smaller companies to assist with presentations. All this as projectors become more accesible and portable their range of uses expands and now when combined with a decent laptop any company can create a credible multi media presentation for use in their business.
I will be talking about the potential of the use of video projectors in your office and business in a future post and you can bet you will be excited as I will be showing you how your company can benefit in more ways than you could imagine possible.
But for now I want to explain why things have changed and what that means for the typical home theater fanatic..
Just a few short years ago the vast majority of video projectors used a techology LCD (you might be more used to seeing it in the context of TV’s) and whilst many people are still using this type of projector and with new and ongoing developments it may come to the top again. But for the time being at least Digital Light Processing (DLP) has started to establish it’s self as the more popular choice amongst those buying home theater projectors today.
The advantages it offers are perfect picture geometry, higher contrast and ratio levels and potentially longer lamp life with out any picture degradation.
So lets look at what at what some of these terms mean and what you should be looking for in a home theater video projector ?
Projection Distances:- This is the distance between the screen and the projector to achieve a sharp image of a given size. The shorter the figure the nearer the projector can be to the screen or wall. Technology has now made it possible to reduce these projection distances making the home theater video projector suitable for smaller rooms as well as giant ones.
By knowing this distance before buying your home theater projector you can calculate how large you expect the image to be in realtion to your intended location of your projector and viewing area.
Contrast Ratio :- A problem associated with projectors of afew years ago was the fact that they would not function well unless the room was totally blackend out. This was quite simply due to the fact the light was not intense enough (contrast ratio was to weak) whilst there have been significant improvements in this area it is still pretty much impossible to use a video projector in a fully lit room.
But it is now quite possible to enjoy movies with out sitting in total darkness and provided attention is paid to the siting and use of lighting in the room you should no longer experience major problems.
Of course as would be the case for a front or rear projection TV or even a plasma or LCD TV of for that matter a standard CRT TV they won’t function in direct sunlight. In my view just some discrete lighting helps add to the ambiance and movie type experience without making it dangerous to move about if needed.
Connecting Your Projector : - Depending what type of equipment you intend to use with your projector will to some extent determine the type of connections you will need. HDMI and component video cables will normally be the best and will be essential for any High Definition images . For older set ups SCART will be used or possible in some cases Super VHS cables. I have found that cables from Best Cables have worked great for my setups so you might want to check them out.
High Definition:- If buying new equipment make sure you purchase HD as anything less will leave your system obsolete in a few years and this could have been avoided for few extra bucks.
Aspect Ratio :- The standard for most of the world now is widescreen or an aspect ration of 16:9 with the advantage of video projection you will be able to enjoy the full benefit of this enhanced viewing option to the full creating a true movie theater picture.
Keystone Correction :- This is clever technology which allows you to site the projector where it is best to do and the circuitry with in the projector makes adjustments so that the picture displays perfectly on the screen. This means until now you needed the projector to be directly in front of the screen or viewing wall but using keystone correction the images can be projected from the corner of the room and still appear straight . Pretty neat huh !
Noise Levels : - Nothing could be more off putting than when the leading man and lady of the movie are about to go in to a romantic clich and all you can hear is the helicopter like fan of your home theater projector whirring in the background so make sure the fan is not so obtrusive as to kill the mood.
Hopefully by now you can not only see why but what to look out for when buying a video projector for your home theater system and to help you with your choice I have included some of the models I think are worth checking out.
