Visual

Sound advice install every type of visual device including Plasma, LCD flat panels and front projector. As with any technology as new products come out we will be the first to offer these to our customers. We have put together so information on the current visual devices that are on offer, and a little on what’s new.

Visual Technology Comparison

Plasma's

Average screen sizes range from 32 inches to 63 inches. Larger plasmas, like a 103 inch, are in production. Plasma images do not suffer from the same degradation at higher viewing angles that LCD TVs do because of the nature of the technology. Plasma displays refresh and handle rapid movements in video about as well as CRT televisions, which is about the standard most viewers expect.

Plasma TVs can suffer from burn-in produced by static images. After extended periods, stationary images "burn in" and produce an after-image ghost which remains permanently on the screen. New plasma TVs have addressed burn-in and significantly reduced the issues of older models. Plasma TVs have a reported half life of 30,000 to 60,000 hours. Half-life is the time it takes the lamp to fade to half its original brightness. Plasma displays are fairly heavy, and may need additional supports to be mounted onto a wall. Plasma TVs report higher brightness and contrast levels than LCDs. Under ideal conditions (no ambient light) this is a true advantage of plasma technology, because LCD TVs are backlit and therefore light must be blocked to create blacks. Plasma Tv’s consume more power than equivalent LCD. Plasma Tv’s cost more to manufacture than LCD and therefore with market forces at work are on the decline.

LCD's

Average screen sizes range from 13 inches to 65 inches. As with plasma, there are larger LCD TVs made, like a 108 inch display. Although the LCD TV can be viewed from up to 176 degrees, there is a "sweet spot" which will produce brighter, higher contrast images. LCD suffer with high refresh rate which when watching fast moving object like a football result in a trail back effect. Although LCD TVs are now available with refresh rates specified by manufacturers as low as 5ms.

LCD TVs do not suffer from burn-in. LCD TVs have a back light that is specified to last between 30,000 and 60,000 hours. LCD TVs weigh less than comparably sized plasma TVs.LCD TVs can often look better in 'real-world' situations. Plasmas are made with a special glass surface that can reflect light, which dulls the brightness and contrast of the image. LCD TVs reflect very little light, allowing them to maintain levels in well-lit rooms. LCD Tv’s are more efficient than Plasma Tv’s. LCD are much cheaper to produce and therefore cost less than Plasma to purchase.

Projectors

Typical screen sizes from as small as 40 inches to as large as 300 inches. Viewing angles are not an issue with front projectors because the light source is coming from in front of the screen, and not from behind. Projectors designed for home theater use will handle 1080p video better than a projector designed for business. Response time is better than LCD especially with the latest DLP display chips. Projectors can suffer from dead pixels. The bigger concern for projector buyers is lamp life. After long term use, the projected image will not be as bright as it was over the first few hundred hours. Lamps are replaceable, however, and cost between £200 - £400.

Projectors now have contrast ratios of 50,000:1 and higher, making them nearly equal by specification to many LCD and plasma TVs. However, with ambient light in a room, contrast and brightness can be significantly impacted. For best contrast that rivals LCD and plasma, low light or no light environments are best. Different specifications are use d to measure brightness in a projector, so it is difficult to compare directly.

What's New

In general, people like the idea of OLEDs because they offer low-power consumption, excellent color gamut, fast response time, and light weight. They can be very thin, bendable, and transparent. And over time, many people believe the bill of materials can be lower than that for LCDs. However, the current process for making OLEDs is expensive, in part because these displays are now only made on smaller-size production lines. This method also doesn't scale well to the size of glass typically used for making larger LCD displays.

Flat Panel Brackets

Pedestal stand - designed to sit TV on a unit or table
Flat bracket - to surface mount against a wall
Angles bracket - similar to flat bracket but with ability to angle the TV down into room, these brackets often are deeper and so sit the TV further from the wall.
Tilt and Swivel - Where the TV needs to be brought out from the wall and angle into a room, these offer amazing versatility but do sit the TV out from the wall when back in the standard position.
Motorizes Tilt and swivel - As the name suggest these are the same as the standard tilt and swivel but have a motor and gearing to bring the TV our from the wall at the touch of a button.
Lifts - These allow flat panel TV’s to be installed in to custom furniture and floor installations to ‘Hide’ the TV until needed.

Other - We have many more specializes brackets to allow installation of Flat screen Tv’s into any area of the house you can think of, From dropping down out of the ceiling to motorising out of custom glass feature wall we can achieve whatever you can dream up.
