-Original component cable
-Original HDMI cable with DVI-toHDMI Adapter
-HDMI-to-DVI cable
*Because this monitor no HDMI connector
This look like HDMI to DVI Cable & Adapter that I use and it still show @1080i only
(No brand, Made in China)
Result of testing
Mode 720P & 1080i via Component cable / No problem
Mode 720P via HDMI-to-DVI cable / No problem
Mode 1080i via HDMI-to-DVI cable & adapter / The screen would just go black and read
out of range signal, change computer display to 19200X1200@60HZ.
***Updated after setting in service mode of Dell 2407 (Step at below)
Now Mode 1080i can display already but 1080P still unable display. Mode HDMI Auto via HDMI-to-DVI cable & adapter / The screen would just go black and read
out of range signal, change computer display to 19200X1200@60HZ.

Now Mode HDMI Auto can display already but 1080P still unable display. Mode 1080P via HDMI-to-DVI cable & adapter / The screen would just go black and read
out of range signal, change computer display to 19200X1200@60HZ.
Change to HDMI-to-DVI cable still same
Question
1. Could this be a cable or adapter issue (Not standard HDMI 1.3)? 
2. Should be find HDMI-to-DVI cable with standard 1.3 that specify support 1080p? Because I found PS3 user can play 1080P@DVI on same model monitor.
Add more detail
After find info by google, I found many topic about problem1080p can't display too.
And got adviced to find high quajlity HDMI 1.3x+ that fully support 1080p

http://www.hdmi.org/learningcenter/faq.aspxQ. Is HDMI backward compatible with DVI (Digital Visual Interface)?
Yes, HDMI is fully backward compatible with DVI compliant devices. HDMI DTVs will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources. However, some older PCs with DVI are designed only to support computer monitors, not televisions. Consumers buying a PC with DVI should make sure that it specifically includes support for television formats and not just computer monitors.
Also, consumers may want to confirm that the DVI interface supports High-bandwidth Digital Content Protection (HDCP), as content that requires HDCP copy protection will require that both the HDMI and DVI devices support HDCP to properly view the video content.
Q. What is the difference between a “Standard” HDMI cable and a “High-Speed” HDMI cable?
Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.
Standard (or “category 1”) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.
High Speed (or “category 2”) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).
