which nvidia driver is safe to use and how do you force it to use dfp and not crt
have tried numrious ways of forcing it to use dfp but it always wants to use crt - pc is connected to a lcd tv via vga 15 pin on card and tv and nvidia site says that it will always use crt if connect via that, but is it ok? and which driver is ok to use? as i have heard some have caused system lockups
not using a monitor - using a lcd tv - yes it works i was just wondering if that setting (crt) is ok or if it would cause damage to the tv, i only have one hdmi connection and one vga(wga) connection, cant say i have had any lock ups as i dont boot to x nor have i installed the nvidia driver yet - its more a server pc atm, but if i can get this sorted i may well get it burning some dvds in k3b
A TV, lcd or crt is a monitor. (electronically speaking)
If you use an RCA (composite) connection then you are sending a composite video signal to the "monitor".
If you use a 15 pin vga cable, you are sending a component signal to the monitor(usually analog signal).
If you use a DVI cable, (numerous pins) then you "may" be sending a component to the.... You get the idea.
I say may, because the connectors are just a connector. The chip in the monitor or TV has the ability to detect if the signal is digital or analog.
So when I said that "if it worked then you probably won't have a problem" it was because the dac/adc chip(microprocessor) has recognised the signal and has adapted to it.
One major concern would be the refresh rate. If it is too high the monitor won't be able to show the picture and you could damage the circuit. So be careful here, but as I said if it works, it should be OK.
Here in Aus, we use the 50Hz 240v system for power, and I set my graphics card to that (50Hz refresh rate). I can set it higher but my lcd screen will convert what ever I send to it back to 50Hz anyway, so I take the pressure (heat/power/work done) off the graphics card by reducing it to the minimum. I use/waste less energy that way.
I hope that has explained what I was trying to get across.

Basically, If it works, don't try to fix it.

(edit) Use the latest nVidia driver available. I personally use the nVidia proprietary driver and not the DKMS (mandriva/plf) drivers. That way I don't need dkms for my system. (end edit)

Reason: Add more to answer question
max refresh i can have is 60hz which i set in xorg.conf - well as long as you say it wont hurt the tv (monitor ) i'll give it a go and see what happens, thing is insured anyway
I feel I should clarify this a bit more , when I wrote...

I meant, ..if it work(s)ed Before, it should be OK. You shouldn't need to change it.
Be very careful, if 60Hz is your country frequency try to get that.( or a multiple, 120)
The manual for my lcd monitor states any input signal will be converted to 50/60Hz depending on country.
its an lg lcd tv and the max refresh it will do is 60hz and no more - i have installed latest nvidia drive and set the refresh in xorg.conf to 60 and only 60 and its going ok, picture looks good
