Migration from CRT to TFT


Hello,
I'm planning to switch my old EIZO 17" to a new TFT monitor. Should I expect any major difficulties? Some kind of major rewrite of xorg.conf?
Currently I'm using that EIZO monitor and another one KFC 15" - both with the same xorg.conf and since they are running on equal resolutions and refresh rates everything is fine. Will I be able to use the same xorg.conf with TFT? I can change something about frequencies or resolutions if that is necessarry, but will it be required some additional modules to be loaded? I heared that there is another module for controling the TFT backlight intensity... Or something different if TFT is connected on DVI instead of VGA output?
Anyway, is there a TFT branch or model that is totaly incompatible with Linux? I want to know before buying
I'm gonna check HCL, too.

My video card is 7300GT (VGA and DVI outputs)

there should be no problem what so ever, if the screen id out of phase when you reboot you can press
[crtl] + [Num Pad +]
To cycle resolutions.
if you have any problems you can always change back to your old monitor with out any trouble.
If you need any more help just ask.
HOpe this helps,

Edit: try to keep to Eizo they have and should always be fully supported, at the moment I have a dual screen setup with one Eizo 17" crt and one Eizo !9" TFT.
Eizo are always trust worthy.
Edit2: There should not need to be any rewrite of your xorg.conf as it should be quite sufficient as it is. the whole oh you need to setup this and that module for TFT is a complete ricers attitude you screen should be fine with your current setup any way adjusting the backlight from default will most likely cause more headaches than it is worth. literaly.

One more thing.
My current EIZO CRT is on VGA output. If I get a TFT which is on DVI, and my video card has both outputs, can both monitors be connected at one time (showing the same picture) ?

yes they can/will,
and if you run the command nvidia-settings then you can configure them to run side by side as one screen this is called xinerama. you can also have two seperate desktops this is called twinview. just have a look and a play and find what suits you best.

enjoy,
Tim(Hoodedmanwithsythe)

Okay, I've got PHILIPS 170X (Perfect Panel).
It is working in Windows and in pure console, but doesn't work in X. Once I get into X that monitor turns off to sleep mode. I suppose frequencies are out of range?
Here is my current xorg.conf monitor section:
Code:
    Identifier     "My Monitor"
    VendorName     "KFC/Elecom"
    ModelName      "CA 1515 DL"
    HorizSync       28.0 - 96.0
    VertRefresh     50.0 - 75.0
I also tried with
Code:
HorizSync       30-83
VertRefresh     56-76
... with the same effect.
I'm currently using that old EIZO. Later today I will try with only the new one connected.
It seems xorg wont switch below 75 Hz. I tried using the following mode line:
Code:
gtf 1280 1024 60
Modeline "1280x1024_60.00"  108.88  1280 1360 1496 1712  1024 1025 1028 1060  -HSync +Vsync
But my EIZO runs still on 75 Hz.

sorry for the late reply

hi there, I am on my winter holiday at the moment so sorry for the late reply.
Try
Code:
nvidia-xconfig
as root.
This should auto conf your Xwindows to suit. If this doesn't work then I will see if I can't get you a default xorg.conf file for your distro.
As usual, Hope this Helps.
Tim
