(Graphics card problem) No display during booting (once in Windows it is fine)

Hi,

Today I replaced my ATI RADEON 9800XT with an ATI RADEON X1600Pro. I installed the correct (and latest) drivers and everything, but before my computer enters windows, I have no display, whereas previously I could see the various tests, etc. during booting.

Here comes the tricky part. On my previous card I had my projector connected to the VGA port on the card and the monitor on the DVI port, and I had a display during startup. Now with the same setup, I don't have a display during startup. HOWEVER WHEN I REMOVE MY PROJECTOR FROM THE VGA PORT AND LEAVE THE DVI ALONE ===> I HAVE DISPLAY DURING STARTUP ON MY MONITOR.

Please advise. Thanks.

did you check if you have display from the projector during startup ?
it mey happend that you switched between main and secondery output
so the projector is the main but when you disconnect it automatic go to secondery.
you should check your driver setting.

you also should check how the two screen are configured :
as extended monitor or dual view ....

The VGA signal is analog and the DVI may digital only, or digital and analog.  To help isolate this, do you have a DVI-VGA converter plug?  Use this on the DVI port and see if it displays the analog boot portion.

haim 96 I checked and I HAVE DISPLAY from the projector during startup.

Also my two screens are configured to the "Clone" mode, as they were with my previous card, and where I had display during startup from both.


Callandor, I have such a converter and this is a good idea - BUT won't I lose any quality on my DVI display by doing that?

Sign your company up to try the MB 660 headset now

Take control and stay focused in noisy open office environments with the MB 660. By reducing background noise, you can revitalize your office and improve concentration.

> BUT won't I lose any quality on my DVI display by doing that?

For desktop screens, the difference is very small.  If you were driving the projector with DVI, the difference would be more apparent, because flaws are magnified.

How small? Can you give me an example, in terms of frame rate or something?

m3lisAuthor Commented:
Is there a way to change the sequence with which the two devices receive signal?
0
 
CallandorCommented:
On a 20" screen, you might see a slight difference in sharpness (or you might not, it can be subjective).  Frame rates are not affected.

I have a 19" screen.

Also, won't my screen then be detected as analog?
0
 
CallandorCommented:
Yes, but being detected as analog doesn't make a big difference in quality, as I was saying before.

m3lisAuthor Commented:
I was just going to try that when I realised that I need a second converter for the projector, to swap the two.

So I kinda need another solution.
0
 
CallandorCommented:
The monitor has DVI and the projector has VGA, correct?  Just attach the converter and connect it to a VGA monitor.
0
 
m3lisAuthor Commented:
Not sure what you mean. My card has one DVI and one VGA, so if I convert one I need to convert the second as well.
0
 
CallandorCommented:
I mean just convert the DVI port, since it is the once that seems to be misbehaving during bootup.

m3lisAuthor Commented:
Yes but then I will end up with 2 VGAs and my monitor is DVI.

CallandorCommented:
If you can get another analog VGA monitor, even a CRT, you can test the port.
0
 
m3lisAuthor Commented:
Logically there is nothing wrong with the port, as when I remove the projector I get display during startup on the DVI monitor.
0
 
CallandorCommented:
Did you install the new drivers before this happened, or did you see this and then tried a new driver?  It may be a driver issue - I have a Radeon X850XT that displays POST on both monitors, one VGA and one DVI.
0
 
m3lisAuthor Commented:
My previous radeon also did that in both.

This is a good suggestion, as I think (not sure though) that I had the card with only the DVI attached, installed the latest drivers and then plugged the projector. Do you suggest driver reinstallation?

haim96Commented:
i know that there is an option to select which port will be main and which  will be secondery.
did you check the setting ?
there is no reason to flip bitween ports !

this is from ATI site :
RADEON 9600 - Display shuts off when Windows loads using a DVI flat panel



This issue affects the following system configurations:
RADEON 9600, P/N 102-A03407-00
CATALYST 3.10 through CATALYST 4.4 Display Drivers
Some users have reported that when their DFP monitor is connected directly to the DVI interface on the RADEON 9600, the display would blank out upon loading Windows; similarly, an Infinite Loop error may appear. If the monitor is connected using the VGA interface, Windows would load as expected.

To correct this issue, download and install CATALYST 4.5 Display Drivers or higher.

it's not the same card , i know but it could be releted ...

I currently have installed ATI CATALYST 6.5, going back to 4.5 wouldn't affect performance?

Also, I have no idea where the option to choose main and secondary is; in the CATALYST CONTROL CENTER I have my DVI screen as MAIN and projector as CLONE, if that is what you mean.
0
 
CallandorCommented:
The only way to tell if it is a driver issue is to try the other driver.  You don't have to go back to 4.5; the instruction said 4.5 or higher.

m3lisAuthor Commented:
Sorry for answering late - I had an important exam these days. I tried going back to version 5.5 and re-installing 6.5 but none of these methods fixed it. Also, I tried disabling my projector through the device manager but it wont fix it either. Any other ideas?

CallandorCommented:
I think you should clean out the old driver and any other remnants with http://www.drivercleaner.net/ and reinstall a good driver.
0
 
m3lisAuthor Commented:
That is what I did - and with that same program!
0
 
CallandorCommented:
As an experiment, can you put the original card back in, just to verify that it still works as before?  If it doesn't, the problem is in a change you made.
0
 
m3lisAuthor Commented:
Old card works as before, i.e. there is display on startup.
0
 
CallandorCommented:
If you switch it into exteded desktop mode, does it continue to do this?  Does the vendor have anything to say about this behavior?

From what I could find out about this card, it was rushed as a gap filler before the X1800 came out, and might have a few quirks.
0
 
m3lisAuthor Commented:
Vendor says to check if the card is properly seated and installed etc, things that I have already checked. I will try the idea of the extended desktop and come back to you.
0
 
m3lisAuthor Commented:
Extended desktop did NOT work - I only have display from the projector during POST.

m3lisAuthor Commented:

CallandorCommented:
I think this card is either broken or was designed to work this way.  Your observation "Logically there is nothing wrong with the port, as when I remove the projector I get display during startup on the DVI monitor." says both ports work properly, but only under certain conditions.
0
 
m3lisAuthor Commented:
I don't think it is broken.

>>>both ports work properly, but only under certain conditions.<<<

I believe so, but I have to find a way to amend these conditions.
0
 
CallandorCommented:
I think you're going to have to contact ATI about this.  They should both work the same way, and you know it isn't the software (the old card works with the same drivers).  By process of elimination, it's the card, and you can't change the hardware on a card.
0
 
m3lisAuthor Commented:
They told me to update the BIOS & chipset drivers but that did not help me.
0
 
CallandorCommented:
I think it's the card itself.  The only sure way to know is to install it in another machine or find another X1600Pro and install it.
0
 
m3lisAuthor Commented:
Sorry my older pc is incompatible with this card and I don't see a way of finding another X1600 Pro.

CallandorCommented:
I think we've gone as far as we can trying to find a solution, then.

If you want, I can close the question and refund you the points.

As there seems to be no other solution, I will accept your offer. Thanks.
