HDMI no output after update to FullHD monitors

Hello

My system:

• AMD Graphics Card
  • GPU : 912-V308-001 (or) R9 290X GAMING 4G
• Desktop mid tower
• Operating System Windows 10 64bit Update 1709
• Video Driver version installed AMD Radeon Adrenalin Edition 17.12.2 Drivers
• Display Devices that does not work with HDMI :
  • BenQ - GL2450HM 24.0" 1920x1080 60Hz
  • AOC M2470SWH 23.6" 1920x1080 60Hz
  • Philips 243V7QDAB/00 24'' 1920x1080 60Hz
  • AOC - G2460VQ6 24.0" 1920x1080 75Hz Monitor (currently using with Display port, does not work with HDMI)
    • The HDMI port works with 4k tv so I know it is functional.
• Motherboard Asus - SABERTOOTH Z97 MARK2 ATX LGA1150 BIOS Version 2702
• CPU Core i5-4690K
• Power Supply Unit Corsair - Builder 750W CX750 or CP-9020015-EU
• RAM 16GB

Issue:

• One morning after regular updates my graphics card stopped sending signals to HDMI monitors that are bellow the resolution of 4k. The monitors, just shows no signal, when you uninstall the drivers sometimes, like once in 4 times it will catch
  the monitor, but if you restart the PC you will again get no signal. The monitors works perfectly with my laptop on HDMI. 3 Of the monitors are fresh from the box. The HDMI port works perfectly with my 4k TV. Tried switching 7 HDMI cables total. Reinstalled
  windows twice, video drivers several times. Currently using a display port for one of the monitors.

 

HDMI Port Stopped Working


I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?

 

Second monitor not working with HDMI

Hi,

I have a AOC monitor hp Pavillion laptop and while trying to connect to the monitor using a HDMI cord, nothing is displayed. Comes up with a No Signal info. I have tried multiple cords : HDMI - HDMI, HDMI - DVI , HDMI - VGA, nothing works. The monitor is
not detected. I have another laptop on Windows 7 and and if I try to connect directly with VGA - VGA, it works, but does not work with HDMI from the same laptop. Basically, it does not work with HDMI at all.

I have updated the latest graphics card, both nVidia and Intel, but no progress.

If I use the same laptop and connect to my hd tv using the same cord it works, but does not work with my monitor. The monitor model is AOC e2450swh. It has support for HDMI. Even if I try to use a HDMI to VGA cord, still it does not display anything.

Any suggestions would be really helpful.

Thanks
