CB272U smiiprx no signal

koz33

So i just bought 2 CB272U monitor to replace an old Samsung HD tv I was using.  I have an Nvidia Geforce GTX 286 with two DVI-I dual link ports capable of rendering 2k.  When i plug one or both of the of the new monitors in, i get almost nothing.  It will start to boot, i will briefly get the windows 10 start up screen, then it goes black, no signal.  However, when i remove one of the HDMI cables from either monitor and plug it into my old Sammy TV, i get dual screen, can log in and set either screen up however i want.  I set them all to 1920x1080 so that i wouldn't run into resolution problems.  I can then take the HDMI out of the working new monitor and plug it into the other new one and it flashes up.  Once I get it working though, if I either unplug the Samsung HDMI or select "display only on screen 1" (1 being the new monitor in this example), the new monitor goes black and I have to wait for it to  revert and get both screens again to operate.  I set them all to 1920x1080 so that i wouldn't run into resolution problems.

In short, the monitors will ONLY, on their own, work when one of the two ports in my video card is plugged into my old Samsung.  They will never work while both plugged in, or when only one monitor is hooked up.  I've also installed the driver for the CB272U.  Hope someone can shed some light on this.  Thanks in advance.

Hi @ koz33  

1. Ensure that the correct type of video cable is securely connected to the correct video source.
2. Confirm that your video source is powered on and functioning properly.
3. Try another video cable if one is available.
4. Connect the monitor to a different video output on the computer if one is available.
5. Reset your bios defaults .
6. Test the monitor by connecting it to a different computer.

If the monitor still displays a "No Signal" message please contact Acer support

Hi @koz33,

A loose connection between your monitor and your PC will trigger the monitor no signal issue. If you're seeing the no signal message on your screen when your Windows system is running, the first thing you should check is whether your compatible video cable is firmly connected or not.
