Hello, This is the first time I have ever posted on a forum so please bear with me. I just pruchased an ATI X850 Pro. This is an upgrade from an ATI 9600 SE 128mb(1 vga, 1 dvi). Before installing the new card I uninstalled all of the old ATI software and drivers. After installing the new card I installed the new catlyst software and drivers. When hooking the LCD monitor to the VGA the monitor works fine. When connecting to the DVI on the card the LCD monitor gets no signal. I immediatley connected the LCD monitor with the same dvi cable to a different computer equipped with a nvidia 7800 and it worked fine. Knowing this I then decided to start over. I re-installed my old ATI 9600 card and hooked up to its DVI and it also worked just fine. Next I re-installed the new ATI X850 and the same problem, no signal to monitor. ATI's website recommended to disable the USB ports and also to use PS2 mouse and keyboard. I did this and again, still no signal. Next I shut down the computer and hooked the monitor up with the VGA cable with a VGA to DVI adaptor and connected it to the dvi, rebooted and it worked. Next I Shut down, disconnected vga w/ adapter and switched back to the dvi cable and once again no signal. Next I connected my old crt via the vga and started the machine. After windows loaded I then reluctantly plugged the LCD with the DVI cable in when the computer was on and it turned on and flashed dvi connection on the LCD and worked ok. I then went into the ATI software and set the LCD as the primary display and rebooted again. Upon rebooting the LCD had no signal again and the crt said out of range. Thinking I had the setting flip flopped I repeated the previous steps and switched the primary display but after reboot it once again had no signal. I have uninstalled and reinstalled the drivers and software several times. I tried the old drivers for my old card, drivers that came with the new card and I downloaded the most current drivers directly from ATI all of this with no luck. Also, the drivers for my motherbard are also the most current. For good measure I actually took my monitor back to where I had purchased and had them hook it up via dvi and it checked ok. As a last resort I disconnected all items that required power but were not needed suspecting insufficient power. Still the same result, no signal to lcd from dvi. I have checked the bios to see if there was anything to enable dvi but could not find anything that pertained to it. Also per another forum I read, I tried toggling the pnp in the bios between on and off but that made no difference. I am at a loss. I have read several forums with the same problem but have yet to find a fix. I plan on exchanging my new X850 for another to assure that the dvi port is not faulty. Any information anyone has I would appreciate greatly. I know it will work when hooked via vga but as you all know dvi is the only way to go when using an LCD. Thanks Alot! My systen is: AMD 2700+ ASUS A7N8X Mother Board Windows XP Pro w/ SP2 1.5 gb DDR 3200 ATI X850 Pro 256mb(1 vga, 1 dvi) 500 watt Antec Power Supply Gateway FPD2185W 21" Widescreen LCD Lite-On 16x Dual Layer DVD Burner 1 Western Digital 120gb HD-8mb 1 Western Digital 200gb HD-8mb 1 Seagate 250gb HD-16mb

Before you go out and buy a new mother board, check your basics. Prior to the X850 did you use the integrated onboard video or did you have a different card installed? If you used the onboard graphics did you disable it? If you used a different card have you reinstalled it to see if it still works? Did you uninstall the old drivers before installing the new card? The X850 requires power, did you hook it up? If so try another adapter to assure you dont have a bad harness. How big is your power supply? Do have several items plugged in that require a lot of power that could be starving the X850? Try a different CRT to assure yours did not fail. Otherwise, if you are dead set on purchasing a new mother board, I am personally a big fan of ASUS. I know several people that are not fans of ASUS, but I have never had an issue personally. What I would recommend is for you to visit www.tomshardware.com and read the reviews. They have a lot of information as to what motherboard would suit your needs best.

HA! Yea, actually she's pretty cool! Anyway, thanks to everybody for all thier help and input! It is very much appreciated!!!!!

Well, thats what I was afraid of. I am courious if the next ATI driver update will cure the problem, although my patience is gone with ATI. I still have time left to return the card, so I guess 7800GTX OC here I come! I am looking at upgrading my system. I was thinking about an AMD 4400+X2, just cant decide what mother board to get, still have to research it. Figure I will throw my old ATI 9600 back in my 2700 and give it to my kid. Then my wife cant get mad at me for upgrading!!!

By the way my monitor is a Gateway 21" widescreen FDP2185W

I guess I dont know much about EDID. I am a very non-techy talker. My understanding of that is that it is what enables a computer to know what kind of monitor is connected. It does recognize the monitor by its model number. If I boot up with a CRT connected via VGA and after windows is loaded I then plug the LCD via DVI the LCD will come on and I can set it up(in the ATI catalyst) so the LCD is primary and the CRT is the extended desktop. When the LCD_DVI was on I also did check via windows to be sure lcd was enabled and set as primary but that made no difference. Even then when I reboot I get no signal to the monitor and have to go back to the vga cable.

Oh yeah...I crossed that bridge already.

Replaced the card with a new one and still have the same problem, still no DVI. I thought maybe there was a hault error hanging " no monitor" or something when using the DVI. I changed it so Hault= none but that didnt work...shot that hope down the drain! I have an old p4 1.6 with linux on it. Think I might put a copy of XP on it and try it in that computer. I did not see anything as or similar to "coordinated video timing" in the catalyst software. This is just frustrating. No help from ATI thus far either. They have yet to get back to me. Its to the point right now where this has turned personal and I have to figure out why it wont work! Its going to drive me nuts until I have an answer.

Relic, Have you heard of this problem anywhere else? I am almost positive it is a card failure but my gut tells me its not. I am almost half tempted to reload the OS to see if that would do anything. Thanks for the reply!
