Why my LG L226WTQ doesn't support 720p and 1080p?

Question

I have an LG L226WTQ wide (native resolution of 1680x1050) hook in a Pioneer DV400V Dvd upconvert player via HDMI to DVI-D cable.

It plays on a Dvd native resolution of 480p but shows only black screen whenever I set it on 720p, 1080i and 1080p?

Any same cases? Most XBOX users can play with 1080p resolution, how can I achieve it?

Audio is hook on a TEAC AG15D Receiver via coaxial cable and doing fine.

Answer 1

Your monitor may not support HDCP over DVI.

Support for HDCP is a MUST to playback video over 480p.

If your xbox has VGA, try VGA. Using VGA you can probably play at either 720p or 1080i.

Answer 2

The manual for the monitor makes no mention of support for video standards (e.g. HDTV input). This is a computer monitor only. You can play DVDs on an internal DVD drive and achieve HD resolution (at least 720p equivalent) by playing the DVD with a suitable DVD player software (e.g. Windows Media Player, Power DVD) while the screen resolution is set to 1680x1050).
