Connections: When it comes to connectivity, the MX613ST offers a lot of choices. Even though there is only one VGA computer connector, it is complemented with a Type B USB computer input, composite video, S-video, HDMI digital, and a Type A USB input for flash dives. Audio in and out are handled by mini jacks, and you will also find a monitor pass through and an RS-232 network connection. About the only thing missing is an RJ-45 for Web connection.
Fan noise: With the lamp set to normal mode, the low- and mid-frequency fan noise from the MX613ST is not distracting, and when you switch to lamp Eco mode, the noise level drops to the point that it is barely noticeable amid normal room noise and speaker output.
Audio Quality: Ten watts is enough speaker volume for a moderate sized room, and the MX613ST does a nice job of providing that audio output without any rumble or boom even at full volume.
User Memory: If your projector is shared with your colleagues, it is nice to be able to store your favorite presets and color settings in user memory. The MX613ST has dual user memories so at least two presenters can store their favorite settings and get to them quickly and easily.
Digital Input: Unlike many of the competitors in its class, the MX613ST has an HDMI input so you can connect digital signals from your computers and DVD players.
3D Ready: Like most DLP projectors, the MX613ST is 3D ready via TI's DLP Link™ technology using active shutter glasses and a computer source outputting a 120 Hz frame-sequential 3D signal. The fact that the projector is 3D ready does not mean it is compatible with all 3D sources on the market, so if you plan to use the 3D option, ask your dealer about compatibility issues before buying.
Warranty Provisions: The MX613ST's warranty period is one year, but its lamp is warranted for an industry best of one year or 2,000 hours of use. This is a big factor in cost of ownership, and even when the lamp needs replacement, it costs only $199.
Maintenance: Since the MX613ST is a DLP projector, you will not be changing air filters anytime soon . . . there are no filters in the projector at all. When the lamp needs replacement, access is provided through the top cover, so even ceiling-mounted units are easy to maintain.
Computer-free Presenting: If you have up to 200 JPEG, TIFF, GIF, PNG, or BMP images recorded on a flash drive, you can plug it directly into the MX613ST's USB Type A connector and run a slideshow without the need for a computer connection.
Auto Source Search: On many inexpensive projectors, you have to search for sources manually. The MX613ST can look for sources automatically. On power up, it searches all seven inputs and selects the first active connection it finds. This is convenient when you have multiple sources connected but cannot recall which inputs are active, the MX613ST will find them for you. If you prefer manual source selection, you can disable the auto search feature.
