With the view through the right side of the 3D glasses, you can see a more pronounced shadow, which is part of the left frame that is showing through. We tried two pairs of glasses, and the same effect was viewable in both, and it looked pretty much the same, with the right eye seeming to get a quite significant chunk of the frame intended for the left eye, and the left getting a small amount of the right eye"s frame. So, it seems that this might be an endemic problem to this display, which could be caused by either the display not being able to switch between the two images fast enough, or the LCD panels in the glasses not switching at the correct time. We did see a similar issue with the Panasonic TC-P50VT20, but it was much less pronounced: that display seemed to do a much better job of seperating the frames for a more convincing 3D effect. We are continuing to investigate.

Compared to the other 3D HDTV that we have in for review (the Panasonic TC-P50VT20), we found that the advantages of this LCD display over the Panasonic plasma were evident in 3D viewing as well as 2D. The image was brighter and had significantly better detail at the high end of the brightness range: details on bright objects were much better represented on the Samsung LCD screen than the Panasonic Plasma. However, the Samsung LCD screen had weaker blacks, with the blacks looking much brighter than the Panasonic Plasma. This meant that more dramatic sequences lacked the impact of the plasma screen. Plus, the LCD screen also had some issues with handling deep blacks. On one section of footage where a title box was overlaid on a black screen, the edges of the box were clearly visible, an effect that was not visible on the Panasonic. We"ll be doing more testing in the next few days, but from our initial testing, it looks like the advantages of LCD screens are carrying over into the 3D world from the 2D one.

The Samsung UN55C7000 is a 3D HDTV, but it doesn"t come with any 3D glasses. To start enjoying 3D, you will need to buy the glasses separately at a cost of $150 each, or $350 for a 3D Starter Kit that includes 2 sets and a 3D Blu-ray disc of Monsters Vs Aliens. The glasses themselves (model number SSG-2100AB) are active shutter ones: each eye is covered by an LCD panel that flickers between on and off in response to a signal sent by an IR emitter on the front of the screen.

The glasses are smaller than the ones that come with the Panasonic TC-P50VT20, and they feel a little more comfortable to wear, pressing down less on the nose. They also cover less of the face, but you definitely don"t forget that you are wearing them. Unlike the Panasonic 3D glasses, they are not adjustable. The glasses are powered by a single CR3 watch battery located under a panel on the left arm. You switch them on by pressing a button on the top of the right arm: the glasses then start looking for the signal sent by the TV. If they don"t detect it within a few minutes, they turn themselves off.

We measured the TV"s viewing angle at 44°. That means, once you get about 22° off center, you"ll only see about 50% of the TV"s maximum contrast ratio. This is an average viewing angle for an LCD HDTV, since the display technology really can"t offer a particularly wide viewing angle. Plasmas, on the other hand, can offer a viewing angle that"s almost a full 180°.

The best way to control power consumption on an LCD television is by tinkering with the backlight control. For best performance, we turn the backlight all the way up to maximum (a setting of 20, in this case). For the final score in this section, however, we lower the backlight until the whites are peaking at approximately 200 cd/m2^ (which equaled a backlight setting of 12 on this Samsung).

A new batch of LCD and plasma TVs has just arrived in our labs, ready for testing. The mix includes some LCD TVs with smaller screens, including three 22-inch sets, a 26-incher, and two 32-inch models. Several have features once found only on bigger, pricier models, including up to four HDMI inputs and the ability to stream Internet video, including movies. Also in this test group are the first 2010 plasma TVs from Panasonic, LG, and Samsung, including 1080p sets and value-priced 720p models.

Among the LCD sets we"re testing is our third 3D set, the Samsung UN46C8000. (Our brand-new Ratings, just posted and available to subscribers, includes full test results for two other 3D models: the Samsung UN46C7000 LCD and the Panasonic Viera TC-P50VT20.) The UN46C8000 is one of seven Samsungs on our test benches now, purely because of the timing of the product releases. We previewed a pre-retail sample of this 3D TV last month, but didn"t include it in our Ratings. Now that this model is available in stores, we"ve bought one to test for our Ratings. It measures just over an inch thick and has edge LED backlighting with local dimming (the first we"ve seen), 240Hz, and Internet streaming from sites including Netflix and Blockbuster.

We"re also testing two LCDs from LG. The LG 22LD350, $430, is a 22-inch 720p set. It has a feature not common at this size, support for 24p, enabling it to display film-based programs without image judder. The LG 47LD450, $1,100, is a 47-inch 1080p set.

The Hisense U8H matches the excellent brightness and color performance of much pricier LCD TVs, and its Google TV smart platform is a welcome addition. But it’s available in only three screen sizes.

The Hisense U8H is the best LCD/LED TV for most people because it delivers the performance of a much pricier TV yet starts at under $1,000, for the smallest (55-inch) screen size. This TV utilizes quantum dots, a full-array backlight with mini-LEDs, and a 120 Hz refresh rate to deliver a great-looking 4K HDR image. It’s compatible with every major HDR format. And it’s equipped with two full-bandwidth HDMI 2.1 inputs to support 4K 120 Hz gaming from the newest Xbox and PlayStation consoles. Add in the intuitive, fully featured Google TV smart-TV platform, and the U8H’s price-to-performance ratio is of inarguable value.

In terms of design, the Hisense U8H is not as svelte as our upgrade pick, but it’s plenty sturdy and doesn’t look or feel cheap. Two narrow, metal feet jut out from beneath the panel and steadily hold the TV. They can be attached in two separate spots, either closer in toward the middle of the panel or out toward the edges, to account for different-size TV stands. The feet are also equipped with cable organization clasps—a nice touch for keeping your TV stand free of cable clutter. Though the TV is primarily plastic, its bezels are lined with metal strips, providing a bit more durability in the long run. I moved it around my home, and it was no worse for wear, but we’ll know more after doing some long-term testing.

The Hisense U8H has some difficulties with banding, or areas of uneven gradation, where transitions that should appear smooth instead look like “bands” of color (sometimes also called posterization). Like many current 4K HDR TVs, the U8H uses an 8-bit panel rather than a 10-bit panel, which affects the color decoding and color presentation process. This is usually relevant only with HDR video and games. When playing games on the PlayStation 5 and Xbox Series X, I saw a few instances where the content wasn’t rendered correctly and displayed ugly splotches of color on the screen. However, this almost always occurred during static screens (such as a pause menu or loading screen); I rarely spotted it during actual gameplay. Hisense has stated that it would address the problem in a future firmware update, but at the time of writing it was still present. This is a flaw that may give dedicated gamers pause, but we don’t consider it to be a dealbreaker for most people.

Finally, like most TVs that use vertical alignment (VA) LCD panels, the U8H has a limited horizontal viewing angle, which may be a bit annoying if you’re hoping to entertain a large crowd. Our upgrade pick uses a special wide-angle technology to address this.

At around $2300 this the 46C7000 is on the pricey upper end of the 46" options scale – justified somewhat by the scaled up features set. There are few plasma options in this size category so LCD is it. Competition hails from the picture quality focused Sony XBR-46HX900, the local dimming 240Hz/480Hz LG 47LE8500, and the super thin Sharp 46LE820UN. 3D compatibility is a feature present in this model that commands attention and will likely be highly desirable for the early adapter set. But it would not surprise me to see the price on this TV drop later in 2010.

Plasma TV production ended in 2015. However, they are still being used and sold in the secondary market. As a result, it"s helpful to understand how a Plasma TV works and how it compares to an LCD TV.

Within each cell, a narrow gap that contains an insulating layer, address electrode, and display electrode, separates two glass panels. In this process, neon-xenon gas is injected and sealed in plasma form during the manufacturing process.

LCD crystals do not produce light, so they need an external source, such as fluorescent (CCFL/​HCFL) or LEDs, for the picture created by the LCD to become visible to the viewer.

Unlike a Plasma TV, since there are no phosphors that light up, less power is needed for operation, and the light source in an LCD TV generates less heat than a Plasma TV. There is no radiation emitted from the screen.

Potentially shorter display lifespan. Early models had 30,000 hours or 8 hours of viewing a day for nine years, which was less than LCD. However, screen lifespan improved and 60,000-hour lifespan rating became the standard, with some sets rated as high as 100,000 hours, due to technology improvements.

Not as good at tracking motion (fast-moving objects may exhibit lag artifacts). However, this has with the implementation of 120Hz screen refresh rates and 240Hz processing in most LCD sets, but that can result in the "Soap Opera Effect," in which film-based content sources look more like a videotape than film.

Narrower effective side-to-side viewing angle than Plasma. On LCD TVs, it is common to notice color fading or color shifting as you move your viewing position further to either side of the center point.

Although LCD TVs do not suffer from burn-in susceptibility, single pixels can burn out, causing small but visible, black or white dots to appear on the screen. Individual pixels are not fixable. Replacing the whole screen is the sole option if the pixel burnout becomes unbearable.

An LCD TV was typically more expensive than an equivalent-sized (and equivalent featured) Plasma TV. However, that is no longer a factor, since companies have ceased manufacturing Plasma TVs.

Manufacturers chose to incorporate 4K resolution only in LCD TVs, using LED back and edge-lighting, and, in the case of LG and Sony, incorporating 4K into TVs using OLED technology.

“This year, Samsung’s market share in the global LCD TV market [which includes LED TVs] is 25 percent. In the U.S., we have around 30 percent market share.”

LEDs have higher contrast ratios and are slimmer and lighter. The PAVV LED 6000/7000 TVs are “finger slim” at 29 millimeters (just over 1 inch). Currently, Samsung’s slimmest LCD TV is 44.4 millimeters thick. The weight of a 40-inch PAVV LED TV is just 14 kilograms, making it easy to mount on a wall.
