BenQ XL2420TX DVI-D stopped working, DP saved me! Question...
I get home and press the power button on the PC as usual but screen remain black. I see Signal not detected. I reset the computer and see Windows boot then when desktop is about to pop screen goes black. :-( Reset again and boot in safe mode, 800x600 kicks in but I select 1920x1080. It works but there is a black border all around the screen, look at screen settings (I haven't touched btw) and ratio is set to Full so I don't know why this black border but nevermind, I uninstall Nvidia driver and reboot, download latest driver while at it and do a clean install. After reboot same black screen when desktop is about to show, I hear the Windows sound. Damn! I'm glad I have a DP cable at home, I plug it and select DP input and it works! I tried to setup 3D and was able to pass the test! Didn't know 120Hz was possible with DP. After all this I tried to plug the DVI-D cable and same blank screen result. It looks like the handshake between the screen and the video card is wrong. So I wonder, will DP limit me in anyway compared to DVI-D I always used?

I knew HDMI could not run 120Hz on this monitor but didn't know about DP, I thought only DVI-D could do it.

[quote="Conan481"]I have the same monitor and my DVI port stopped working too. [/quote]Really!? How it happened? What is weird is it works as I was able to boot in safe mode and change resolution to 1920x1080 but like I said with black border. Maybe it's the Full HD 120Hz that cause a problem? I'm so glad DP is working and that it supports 3D. I had no money to get a new monitor now.

Odd, seems unlikely that it's a hardware failure and more likely something introduced in the driver now that it's confirmed by the both of you. I'd file a bug report if I were you guys, you never know when you will want to resort back to that DVI connection and it's easier for Nvidia to correct a bug if you know the last known good working driver. http://nvidia.custhelp.com/app/chat/chat_launch http://surveys.nvidia.com/index.jsp?pi=6e7ea6bb4a02641fa8f07694a40f8ac6 http://nvidia.custhelp.com/app/answers/detail/a_id/3141 Or try these numbers US/Canada: 1-800-797-6530 International English: +1-408-486-2000 Give detailed information, such as OS, GPU, CPU, Motherboard, overclock info, memory specs, power supply, installed programs, model #s of connected displays and connection types, last known working driver, etc.... Or you can try posting in the driver feedback thread, going through Technical Support is a better option though. http://nvidia.custhelp.com/app/chat/chat_launch

Why on that day the screen was black at wake up is a mystery.

I was sure the monitor was dead but decided to buy a DP cable and it worked right away. Kind of annoying but I actually needed that DVI port on the videocard for something else anyway. LOL. I'm guessing it's a faulty input controller/board on the monitor. I'm sure I can get it fixed or replaced under warranty...

I don't remember when I bought mine, 2011 maybe?

There's been similar problems posted in the Driver sub-forum about issues when monitors wake up. Manuel has stated that they expect to release a fix in the next driver. With any luck, it will solve your issue. [quote="ManuelGuzman"]We believe we are close to root causing this problem and have a fix in the next driver. [/quote]

Thanks D-Man11, went there and asked Manuel, he [url=https://forums.geforce.com/default/topic/927166/geforce-drivers/waking-monitors-from-sleep-resets-desktop-as-if-secondary-display-has-been-unplugged-and-plugged-ba/post/4898571/#4898571]replied here[/url]. This is very strange because like I said I had the same driver for months, will try to ask Manuel about this.
