XRGB2+ with LCD monitor

[pinkstone]

Hi. Recently, I changed my old Viewsonic 19� CRT monitor by a Dell 2407wfp. While it works beatifully with my everyday applications, with the XGRB2+ the image I getting  is shaked all over the place. I tried to play with DTC_TYP and USR_DTC values in conjuction with the Dell�s phase settings but it�s no use. I know the XRGB series are not recommended with any LCD monitors but don�t know why. Any chance I can correct this or should I wait for the XRGB3?. Thanks in advance.

P.S.: By the way, I use the D1 and RGB (Japanese Scart) inputs on the XRGB2+ and works very well on the CRT.
