I don’t think installing CTX driver will hurt you
Well, this is slightly complicated. First of all, both the panel and the CRT are show up as “Plug and play monitor” in device manager. In theory, the first one should be the laptops monitor, but if not… Secondly, both monitors mimic each other. This is more or less okay with resolution but that cannot be said about the refresh rate. Unless I am terribly wrong, LCD (panel in my case) can go very bad then refresh rate is set to let’s say 100Hz.
That said, I have finally managed to get my CRT working at 100Hz. I did it by completely shutting off the panel, setting CRT as a primary monitor and then overriding the refresh rate settings (I have no idea why it didn’t work yesterday). However, I am not sure what would happen if the computer freezed. I would have to power it off and I am not sure if the display settings would remain unchanged (panel shut off, CRT as a primary). If not, the panel might go wrong.
Have you got any ideas of a more solid and reliable solution?
