Our take on the LG DN798

by Loren Barstow

Get the most out of your DVD library. LG's DN798 can upgrade DVD video for a better picture on any HDTV with a digital input. It can even upconvert the picture to 1080p resolution, for vibrant, lifelike images with the latest 1080p-capable TVs. You'll experience a smooth, filmlike picture from all your favorite movies and TV show box sets.

You can also use the versatile DN798 to enjoy your favorite tunes. It plays standard CDs, home-burned discs, and discs filled with MP3 and WMA files. Or, pop in a disc with JPEG images for a cool slide show right on your television screen. The player's USB input expands your options — simply plug in a portable USB memory drive for disc-free enjoyment of your favorite digital music and photos.

HDMI Output: The LG DN798 single-disc DVD player has an HDMI output, in addition to a component video, S-video, and a composite video output. The HDMI input supports both video and audio on a single digital connection.

1080p Video Upconversion: This unit will upconvert DVD video signals up to 1080p. The output resolution can be set as follows:

Output Connection Available Resolution
HDMI Video Out 1920 x 1080p
1920 x 1080i
1280 x 720p
720 x 480p
720 x 480i
Component Video Out* 1920 x 1080p
1920 x 1080i
1280 x 720p
720 x 480p
720 x 480i
S-Video Out 720 x 480i
Video Out 720 x 480i

Note: *Only non-copy protected discs can be upconverted to 720p, 1080i, and 1080p resolution through the component video output. If the disc is copy-protected, it will be displayed at 480p resolution.

Digital-to-Analog Converters: This unit is equipped with a 14-bit, 108MHz video D/A converter, and a 24-bit, 192kHz audio D/A converter.

Playable Discs: The DN798 is capable of playing the following discs:

  • DVD:
    • DVD Video
    • DVD-R, DVD-RW (including discs recorded in the VR (video recording) format)
    • DVD+R, DVD+RW
    • MP3, WMA, JPEG files on DVD-R, DVD-RW, DVD+R, or DVD+RW
  • CD:
    • Audio CD
    • CD-R, CD-RW
    • MP3, WMA, JPEG files on CD-R or CD-RW

USB Input: The front-panel mounted USB input allows you to connect a USB Flash drive and play MP3/WMA music files or JPEG image files. This unit supports only USB Flash drives with FAT16 or FAT32 formatting. The player supports USB devices with up to 650 files.

MP3/WMA Playback: Discs containing MP3 files should be recorded at a bit rate between 8 and 320 kbps. WMA files should be recorded at a bit rate of 32 to 256 kbps. The CD-R physical format should be ISO 9660. The total number of files in a folder should be less than 650 files.

JPEG Playback: It is recommended that JPEG image files of less than 5 million pixels be recorded onto CDs or DVDs to avoid long file loading times. Like MP3 and WMA, no more than 650 files should be in any given folder. You can zoom in 2 steps (4x and 16x) and move around the image while zoomed in. Music files on the disc can be played back at the same time as the photo files. (The zoom function and music/picture playback are not available when the resolution is set to 720p, 1080i or 1080p.)

Black Level Expansion:  You can turn on/off the unit's Black Level Expansion (B.L.E.) to select the black level of playback. When on, the black level is expanded, with a 0 IRE cutoff. When off, the black level is standard with a 7.5 IRE cutoff.

Parental Control: You can limit the playback of certain rated DVDs based on their content. When the parental control function is "locked", you can select a rating of 1 (most restrictions) to 8 (least restrictive). When the function is "unlocked," parental control is not active, and the disc plays in full. Parental Control is protected by a password.

Dynamic Range Control: When watching a DVD, you can compress the dynamic range of the audio output, allowing you to listen to a movie at a lower volume without losing sound clarity. The DRC can be turned on or off as desired.

Markers: You can start playback from up to nine memorized points. You can set a marker at a point on the DVD where you'd like to quickly return. After markers are set on the disc, you can search for a specific marker by number, and begin playback from that point.

Last Scene Memory: The player memorizes the last scene from the last disc that is viewed. The last scene remains in memory even if you remove the disc from the player or switch off the player. If you load a disc that has a memorized scene, the player automatically recalls that scene.

Remote Control: The supplied remote control can operate the DVD player, as well as TVs made by LG/GoldStar, Zenith, Samsung, Sony, and Hitachi. You can control the input source, volume, and power of TV.

Works Well Enough

Written By j, Bakersfield, CA on Thursday, August 02, 2007
Good price and flexible with two choices of audio outs (coaxial and optical...I chose optical). One button "Resolution" cycles through the settings from 480p all the way to 1080p and everything in between. I didn't notice the difference from 480p to 720p (my TV) though. The one problem I have, and this being my 2nd upconverting DVD player, is with the hit-and-miss of playing all of my DVD library. Some DVDs play, some don't. Also the remote is either way slow or doesn't read some button presses at all. Overall a decent value among the brand-name competition.
