Product Review (February 2008) - Mitsubishi
LT-52133 52-Inch HD 1080p LCD Television

By Kevin Nakano


Flat panel displays have become so popular that conventional picture tubes are being treated like, well "tubes". Selling large bulky sets have become difficult for stores when new, attractive flat panels are flooding the market. Mitsubishi recently introduced their new LT-52133, a large Full HD 1080p 52" LCD display that measures 48" wide, 30.4" high and only 5.7" deep. Add the base and the height increases by 2" and allows the display to swivel up to ±30 degrees. The display weighes only 84 pounds with the stand and 75 pounds without it, making it compatible with a wide variety of wall mounts. While the flat panel can be easily on a table or cabinet, there are some nice advantages when using a quality wall mount such as the Omnimount UCL-X Dual Arm Cantilevel design. Once mounted, the display can be tilted up or down and adjusted horizontally at a much wider angle than is offered with the stand.

The Mitsubishi LT-52133 features x.v.Color™ support and Mitsubishi’s Full Spectrum Color™. The x.v.Color™ is a relatively new standard for HDTV and enables many more colors than conventional HDTV displays resulting in more realistic looking images. In addition, Mitsubishi’s Full Spectrum Color™ results in 25% more color than standard LCD displays thus producing more vivid reds and yellows. The LT-52133 also features a Color 4D Noise Reduction and PerfectColor™ that allows for advanced color processing and color adjustment. The three HDMI 1.3 inputs with Deep Color give the display the ability to support more colors and gray levels, making it less susceptable to false countouring (banding). A pair of built-in speakers are provided for those with a basic set up. Video and audio can be carried through a single HDMI cable for simplicity. The integrated ATSC and NTSC tuners let users see local terrestrial broadcasts in standard and high definition without having to subscribe to cable or satellite. The tuner is QAM cable compatible, but does not support an integrated Cable-Card slot. The amazingly high quality picture being broadcasted over the air for free is always impressive. More people should be taking advantage of this. The LT-52133 has an attractive chassis design and offers a wide 178(H) x 178(V) viewing angle. The surface of the screen is not shiny, so screen reflection issues are minimal. The pixels have a fast 8-millisecond response time that vitually eliminates motion blur commonly seen on earlier LCD displays. The LT-52133 features a full 10-bit per color display panel that creates over a billion possible colors with the Plush1080p® digital video processing. All video inputs are upconverted to the native 1080p.

Panel Controls
The LT-52133 has a narrow set of hidden controls on the right side. There are nine buttons that give the user control of the unit. The Power button is on top followed by Volume Up/Down, Channel Up/Down, Format, Menu, Guide, and Input. All of the buttons except for the Power and Input buttons have secondary functions depending on the mode of the set. A small pinhole button is provided to reset the internal processor in the event the unit becomes unresponsive to the user. This is a common feature on products that have a microprocessor, but we never encountered any issues requiring the use of it.

Five RCA connectors are provided for either component (Y, Pr, Pb) or composite video with two channel audio. The Y input carries luminance information and is common to both video format used here. The side panel jacks provide an easy way to connect video to the display when using a camcorder, portable video player or game console. For the best video performance, the component video inputs should be used on this interface.

A really nice feature of the LT-52133 is the USB interface on the side. This provides an easy way to show off your picture to your family and friends. Upon plugging a USB memory stick into the side of the LT-52133, the USB menu pops up on the screen. Photos can be shown in a simple slideshow or displayed from a list of thumnails on the screen. Settings can also be configured for the photos. Manual or automatic slideshows are possible with the content repeating once, twice or continuous. The slide interval can be set to 5 seconds, 10 seconds, 30 seconds or 1 minute.

Rear Interfaces
The back of the LT-52133 has two antenna/cable inputs (via F-connectors), a coaxial digital output, and 3 HDMI™ 1.3 inputs with Deep Color support. The digital output can be connected to an A/V receiver for full Dolby Digital decoding for over the air or cable programs. We were happy to see the inclusion of three HDMI inputs which helps eliminate the need for an external HDMI switcher. Due to the deep placement of the HDMI inputs, some active cables with large connector assemblies may have problems plugging into the tight quarters. We found this to be the case when using VizionWare and Altona active cables. Luckily, most users will be using standard HDMI cables connected to their components and should have no problem at all. We connected the antenna input to our Terk TV38 terrestrial rooftop antenna for local reception.

Analog Connectivity
The back of the LT-52133 supports legacy analog formats including composite, s-video, and component video. Two sets of composite/s-video inputs along with their corresponding two channel audio is provided. There are also two sets of component inputs available that support both standard definition (480i/480p) and high definition (720p/1080i) video. Line level inputs and outputs are also provided for use with external video recorders. The LT-52133 has a feature that automatically detects a new video input when it is activated. The on-screen information notifies the user of the new input. Due to the number of cables typically connected to this type of display, a pair of cable ties with rivets that attach to the back are provided for better cable management.

Remote and Menus
The remote included with the LT-52133 has a nice layout, with fairly large buttons making it easy to use. The design work well in dark environments thanks to the built-in backlighting. A top slider switch on the remote selects different components from other manufacturers (Refer to the User's Manual for a list of supported products). Standard (Power, Sleep, Input, Format, Volume, Channel) and navigation buttons are provided. Dedicated buttons for Guide, Info, Audio, Video, Menu, and Exit are located just below the navigation buttons. There are also VCR/DVD buttons (Play, Pause, Stop, Record, Forward, Backwards) near the bottom for convenient control of these components. The F1 thru F4 keys are used with Mitsubishi's NetCommand. The buttons can be used as alternate keys for some components operating independent of NetCommand. A Low-Battery condition will be displayed by a blinking power key.

The menu system on the LT-52133 is similar to other Mitsubishi displays we have seen. The top level menus are Setup, Captions, A/V and Lock. The Setup menu is used to select the Language (English/Spanish), Scan for active channels (Air/Cable), set the Clock, adjust the Timer, and define the Energy settings.

The Captions menu supports both analog and digital channels. Caption data on the analog channels can be decoded from the ANT 1/2 and INPUT 1/2 inputs. Broadcasters can send either standard closed captions or text service. Standard closed captions follow the dialogue of the program and display in a small section of the screen. Text-service closed captions often contain information such as weather or news and cover a large portion of the screen. Caption data for the digital channels is only supported on ANT 1/2.

The A/V Menu has submenus for Audio (Speaker Control, Bass, Treble, Balance, and SAP/Stereo), Video (Picture Mode, Contrast, Brightness, Color, Tint, Color Temp, and Backlight Level), Perfect Color (Adjust the saturation of Magenta, Red, Yellow, Green, Cyan, and Blue for the current image source), and Reset. The Picture Mode allows the user to select from four different (Brilliant, Game, Bright, and Natural) display settings. Color Temperature can be set to High or Low (6500°K).

The Lock menu allows the user to lock the display based on Ratings or Time. The side panel controls can also be locked to prevent curious fingers (little kids) from changing the settings. The Ratings lock is controlled by the Parent Menu, which allows the parent to lock the content based on TV Ratings (TV-Y, TV-Y7, TV-G, TV-PG, TV-14, and TV-MA), TV Content (FV, D, L, S, and V), or Movie Ratings (G, PG, PG-13, R, NC-17, X, or Not Rated). For Time based control the user can enter the Start and Stop time for TV viewing.

Display Formats
Several display modes are available on the LT-52133 that correct for geometric differences in the source material. The Standard mode, which is the default mode used with HDTV (16:9 aspect ratio), evenly distributes the image across the full screen. This mode is also used with anamorphic (16:9 enhanced) DVDs. The Expand mode is intended for non-anamorphic DVDs that would normally stretch the image horizontally and insert bars on the top and bottom of the screen. This mode stretches the image vertically correcting the aspect ratio distortion, while cropping some of the video on the top and bottom to reduce the black bars that are normally seen with these discs. This emphasizes the importance of anamorpphic DVDs and why they maximize vertical video resolution. Ideally, you do not want to use this mode, but it exists to make non-anamorphic DVDs viewable on this widescreen display.
The Zoom mode essentially increases both horizontal and vertical overscan to help eliminate the top and bottom black bars on movies that have wider aspect ratios. This will also crop the right and left side of the picture, so you will lose some of the original picture on the sides. The Stretch mode is one of my favorites as it takes a 4:3 source and distributes it across the full screen in a way that doesn't make it look too objectionable. This is accomplished by stretching the sides more than the center area, resulting in a fairly good looking center picture. However, scenes that pan will quickly reveal the technique used here to help the center of the image. The Stretch Plus mode works great for standard 4:3 broadcasts, but not for 16:9 source material. The Narrow mode exists for 4:3 content that uses gray bars on the right and left side of the image to preserve the aspect ratio on this display. It must be noted that the Expand, Zoom, Stretch, Stretch Plus and Narrow modes are not available when using 1080i or 720p video.

Calibration
Our color temperature measurements were made using our Sencore CP5000 All-Display Color Analyzer. The graph shows the results of the factory settings (in red) using the Natural Picture Mode with the Color Temperature set to Low. The LT-52133 tracked the ideal 6500°K well at the higher IRE levels, but was on the high side at the lower IRE levels. Mitsubishi does not have a user-level menu for adjusting color temperature at the bias and gain levels. Doing so requires going into the service menu, which can be dangerous for those lacking experience in calibration. Once adjusted, the LT-52133 produced a stable 6500°K across all IRE levels. Overall, the display exhibited good shadow detail with an impressive 53 foot-Lamberts of light output.

Display Primaries
The primary colors produced by the LT-52133 were measured using the DataColor ColorFacts Pro 6 software with a Milori Trichromatic-1 color sensor. The CIE chart indicates where the ideal primaries are located where the three small points make a dark triangle. The measured primary colors are marked by the red, green and blue markers connected together with the white triangle. Only colors inside this triangle can be produced by the display by definition. As you can see from the data taken the measured primary colors were near ideal with this display. Colors were well saturated and looked excellent with accuracy confirmed by the measurements. Skin tones had a natural look without looking oversaturated. Secondary colors were also quite accurate on this display.

Setup
We had several sources available to test with the LT-52133 including our Dish Network ViP722 HDTV DVR, Sony PlayStation3 with Blu-ray, Toshiba HD-A1 HD-DVD player, and OPPO OPDV971. All sources supported HDMI with the exception of the OPPO, which used a DVI to HDMI cable. Power was connected to a Panamax MAX 7500-PRO power conditioner.

Performance
Picture quality on the LT-52133 was excellent with the majority of our viewing done with the new Dish Network ViP722 high definition satellite receiver. The set-top box was connected through an HDMI cable and was set to output 1080i video. Seeing high definition content was a great experience on this display. Terrestrial (over the air) from our local stations here in Los Angeles worked perfectly. Colors were well saturated and the picture took on a three-dimensional image. Programs such as Las Vegas produced excellent video quality and the many night shots revealed the great shadow detail this set is capable of. Bright scenes were equally impressive with the high light output this panel is capable of producing. We had to drop the contrast down from the full factory setting, yet there was still plenty of output for a punchy picture.

Blu-ray discs looked even better with full 1080p coming from our PlayStation 3. We could not come up with a better combination for truly reference quality video performance. The LT-52133 fully supports 24, 30 and 60 Hz frame rates. Our results were mixed with standard definition DVD content. The best results came when using our OPPO OPDV971H DVI-enabled DVD player connected to the second HDMI input on the LT-52133 display. This player has both excellent deinterlacing and scaling, but we let the display scale the native 480p from the player and the results were great even with many of the torture tests on the HQV disc. The analog inputs on the display did not work as well with some noticeable artifacts showing up using the same test disc. The real problem turned out to be our 400-disc Sony DVP-CX985V DVD changer. It became clear that this was not a good combination with this display. Both motion artifacts and color bleeding were obvious with this set up. As it turns out, the Sony DVD changer has some issues that became very obvious with this high resolution display.

Status Display
Pressing the INFO key on the remote activates the on-screen status display. Here in Los Angeles most of the common displays are active as seen in the picture here. The antenna input, channel, program, program description, received signal type, screen format, V-chip rating, audio type, day and time, and signal strength are displayed. The remaining time on the sleep timer will be displayed next to the day and time in the same window. Pressing the timer button increments the sleep timer by 30 minutes, for up to a maximum of 120 minutes.

ChannelView
The LT-52133 features ChannelView, a system that provides channel listings that are accessible via the GUIDE key on the remote. ChannelView displays only digital channel names and program information as sent by broadcasters or local cable providers and may be incomplete depending on the area. To receive ChannelView updates, the TV should have the Energy Mode set to Fast Power On with the TV clock properly programmed and should have the power off for a while each day. The information we received in Los Angeles was quite impressive for something broadcasted over-the-air.

Conclusion
The Mitsubishi LT-52133 is a feature rich LCD display that looks fantastic with both high definition and standard definition content. The video performance in terms of deinterlacing and scaling was excellent. Feeding 1080i video from our Dish Network box produced pleasing results that made watching television an enjoyable experience, especially with high definition content. The LT-52133 has three HDMI 1.3 (with Deep Color and x.v.Color™ support) inputs making it easy to interface to multiple high quality sources such as high definition set-top boxes, Blu-ray players, and HD-DVD players. This provides the much needed HDMI video switching required for today's home theater setups. The LT-52133 produces a bright, high contrast picture that will work in rooms that have ambient light. We liked this display so much that we decided to keep it in our system.
