REVISED: Custom Resolution Guide for HDTV-HTPC
Here are several progressive scan Custom Timing and Resolution strings for
the ATI Radeon card, created with PowerStrip 3.28 build 342 and Catalyst 3.1
WinXP ATI drivers, displayed on a Mitsubishi W55819 1080i 16x9 HDTV. All are
1080i/ 540p based timings. Scan rate is exactly 33.75 kHz and refresh rate is
59.94 Hz for all resolutions. Please note I am using a Key Digital VTCA-2
Transcoder to connect to my HDTV, not an ATI HDTV dongle adapter. If used with
the ATI HDTV adapter you will get a virtual desktop almost every time.

time. Then, in PS 3—display profiles—advanced timings—custom
