The problem with CRT TVs is they're usually only designed to take TV signals. I don't see any detailed timing information in the service manual. Usually you are limited to 480i and 576i, so you would need a GPU capable of interlaced output. "Automatic (HDTV)" will give you the timing parameters for 480i and 576i. I should probably add that to "Automatic (CRT)" as well.

For 480i, enter 1440x240 @ 59.94 Hz with "Interlaced" enabled:


For 576i, enter 1440x288 @ 50 Hz with "Interlaced" enabled.

The TV might support the progressive equivalent (1440x240p) with the same timing parameters and pixel clock:

No one was replying me, and so far there are new answers to other questions there, they made my question get lost, so...
I managed to get the same configuration, and even customize it, with an old nvidia card and it worked flawlessly (using progressive mode), but I don't want to be switching between my dedicated cards, that's why I'm still trying to get intel to work.

I'm going to try your suggestion though.
