GT 630 out of sync during bios until welcome screen

skyhide · Aug 5, 2013

Hey guys waddup, Im stuck with this for weeks now since I swap Geforce 9500 GT for Geforce GT 630, it kept giving me out of sync message while booting up at bios plus I cant even enter safe mode cause the out of sync message but once its at the Welcome everything works just fine. I changed current LCD to CRT, with the CRT it does boot fine in both Bios + Safe Mode but not with the LCD monitor... besides when I go into screen resolution and click the drop down list it said 1024x768 (Recommended) but even when I can go higher to 1280x1024... funny thing is when I try to change it to 1024x768 it saids out of sync cause by the refresh rate being too high for the LCD it only allow me up to 75 Hertz not 85 Hertz which is what the 1024x768 recommended is about.

I google`d this problem over and over with different words but nothing useful came up.... besides getting another LCD that does support up to 85 Hertz or a more decent model nowadays. This is my last place to ask lol. Thanks

You have no purpose in running any display at 85 herts. It is thought that at most you can only see 30 frames per second. Things at 60 frames per second look better but you only see split bits and pieces of some of those frames. You only actually catch around a full 30 frames per second. So there is no reason to run at 85. Turn it down to 60 hertz.

Well the Hertz dont really matter to me as long as I dont see things blurry or distort, I turned it down to 75, 72, 70 and 60 at 1024x768 then restart computer and same out of sync message with the hertz set at 85 hertz... I wonder what makes it recommend me at 1024x768 with that 85 Hertz.. and not 1280x1024 like Geforce 9500 GT did..

does your motherboard happen to have integrated graphics?

When booting the Geforce GT 630 is outputting a display mode outside the frequency range supported by the LCD. You need to either swap the card or get an LCD with a greater frequency range. There is nothing you can do to change the default mode that this new card is operating at boot.
You likely have an old lcd with a limited range but many cards would still default to a lower frequency at boot and not produce the out of sync condition of this Geforce GT 630 card.

are you using vga for your lcd? can you try using dvi at all?

skyhide · Aug 5, 2013

mauller07 :

LCD is a VGA plug but GT 630 requires DVI so I got the VGA to DVI adapter for it.

Before you go and spend close to $100 or more on a new LCD, you may try just returning the card and getting a similar card from a different manufacturer.

Although I am really amazed if the bios on the card defaults to 85 hertz

I found this: http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/windows-7-changes-screen-resolution-on-boot-up/13c17468-0d70-4827-a559-dca0fa558a69

Im stuck at step 3 cause I dont see random numbers and letters... all I see is this:

Anyone familiar with this?

Presler :

Do you mean that I have to set it to 1024x768 85 Hertz? then apply the setting? If I click on "Customize..." then "Create Custom Resolution..." then type in 1024x768 85 Hertz, Test, it will say Duplicate Resolution. Custom resolution 1024x768 at 85Hz (32-bit) already exists in PC section.

Presler :

The same "Custom resolution 1024x768 at 60Hz (32-bit) already exists in PC section." But it only happens when I leave Timing section as "Automatic" if I change it to manual or CVT it would go out of sync with the current resolution im using (1280x1024)

it could be an incompatability between the card and the bios when the pc is booting, try updating to the latest bios for your motherboard.

skyhide · Aug 15, 2013

I only left the LCD monitor plugged in and did what you said but still the same after restart, about the bios, its the bios from Asus website itself.

Beta Version 5001

I already bought a new LCD waiting for arrival. Thank yall for helping me out much appreciated!

bas94041 · Aug 15, 2013

From the description your issue is that the cable or connection from the video card to the LCD is not passing the correct mode supported by the LCD to the display card when the PC is turned on. When you boot up the display mode supported by the LCD should pass to the video card via the pinout of the video cable connection. This is working on the old CRT and not on the LCD. Making changes in the windows display config will NOT fix this as you have found. These changes only affect the display settings when windows loads.
Try a different cable or a different VGA to DVI adapter but as this operation is working with the CRT it is likely that this particular LCD and this newer video card are not properly handling this function correctly. Some LCD's (and CRT's) are very limited in the frequency range supported. This is what you describe in your problem. No fiddling in the windows registry will fix this.

update your bios, it could actually be an incompatibility during post.
