mnmahir,

When looking at the Screen Resolution jpg, it list Computer 1. What is computer 1, a laptop?

Hi,

Sorry if the picture confuse you. I'm actually connecting both HDMI and VGA on the same monitor.  "1." is the display connected with HDMI and "2." is the display connected with VGA. Currently I'm using the "2" display which is connected with VGA and the "1" display which is connected with HDMI is being disabled so I can see the screen through VGA input since HDMI input is not possible.

here is the new screenshot: http://i.imgur.com/9UNNyis.png

You cannot have one computer connected to both of the monitor inputs at the same time. I think that is what you are doing?

* Turn the monitor and laptop(?) off
* Disconnect all cabling from the monitor including the power cord
* Disconnect all monitor cabling from the computer
* Press the monitor power button in for 10 seconds
* Reconnect the power cord to the monitor
* Turn on the computer
* Turn on the monitor
* Connect the HDMI cable to the computer HDMI out port
* Connect the other end of the HDMI cable to the HDMI in port on the monitor

What appears on the screen?

I have tried follow your instruction but same thing appears on the screen "No HDMI cable".

Yes, I  connect one computer to both monitor inputs (HDMI+VGA) but same thing will happen even I use only HDMI input without the VGA.

Here is a picture I tested with dual monitor: http://imgur.com/81hDuEU

and also screenshot/printscreen test: http://imgur.com/JK8F6ak

As you can see in the 2nd display the computer detects S2340L monitor with HDMI as #1 display but on the S2340L monitor screen it only display "No HDMI Cable" message. Why won't the monitor display anything??

I don't think it's my computer fault because the HDMI port from my computer's GPU works fine on another monitor or HDTV.

I found a thread which I think he also might having the same problem as me:

Please help me solve this problem. This is my first HDMI monitor with Dell and it already scares me to buy another Dell HDMI monitors in the future.

You must do each and everyone of these steps...

* Turn the monitor and laptop off
* Disconnect all cabling from the monitor including the power cord
* Disconnect all monitor cabling from the computer
* Press the monitor power button in for 10 seconds
* Reconnect the power cord to the monitor
* Turn on the computer
* Turn on the monitor
* Connect the HDMI cable to the computer HDMI out port
* Connect the other end of the HDMI cable to the HDMI in port on the monitor

I followed each of every step by step for 10 times already. The monitor start with auto select input source with "No VGA cable" message. I tried change the input source to HDMI it still give me "no HDMI cable" message.

By the way, what can the monitor do when pressing the monitor power button for 10 seconds while the monitor power cord is disconnected?

To me, this sounds like a HDMI cable fault or a computer HDMI fault. The 10 second thing "resets" the monitor to factory defaults. What specific computer is this? What video card is in this computer? List every available video out port on this computer.

It's a PC not a laptop...

My computer specs:

• OS: Windows 8.1 (64-bit)
• Motherboard: ASUS P8H61-M LE
• Processor: Intel Core i7-2600 3.4GHz
• RAM: 8GB
• Video card: SAPPHIRE DUAL-X R9 270X
  • Available video out port:
  • 1 x HDMI (with 3D)
  • 1 x DisplayPort
  • 1 x Dual-Link DVI-D
  • 1 x Dual-Link DVI-I

I don't think the HDMI cable or the computer HDMI is faulty. I tried using the same cable on another monitor and my HDTV it worked fine.

Connect the monitor through your DVI-I to VGA setup. Then go into the AMD Catalyst Control Center and make sure HDMI output is set to 1920x1080 60Hz. Then try the HDMI to HDMI setup again.

How do I make sure HDMI output is set to 1920x1080, 60hz? I can't find the HDMI output settings.

Is this right?

It's already 1920x1080, 60hz by default.
