My HP w2207h screen (used as extension for a laptop) suddenly goes black

[goguy58]

My HP w2207h screen (used as extension for a laptop) now suddenly goes black after just a few minutes of operation. Displays "No signal - Going to Sleep". Tested the HDMI cable and it is not the culprit. Unplugging and replugging makes the screen to properly display - but only for one second.

Turning the screen on and off has no effect (the "no signal" message remains). The only way I can recycle it back to a live display (for couple minutes) is to restart the laptop - which I cannot practically do every few minutes. Any suggestions?

Welcome to HP Community
 

Since the display comes back after restarting the Laptop, it could be an issue with the drivers installed on your Notebook

I suggest you try connecting the monitor to another computer and check if your face the same issue

Keep me posted

Thanks for the suggestion, KrazyToad. I hooked up the monitor to a desktop butit also behaved weirdly: it displayed fine for a few minutes butit  contained an error message "Incorrect Input Signal - Please change resolution to 1680 x 1050 60 hz" that traveled constantly across the screen. The resolution was already correctly set and the error message could not be removed (trough various tried actions). Eventually, after 5 minutes or so the screen went black.

So the question remains: a monitor gone rogue or bad video/adpater drivers?

Since you have already confirmed the issue persists with another computer, then it is a problem with the monitor

I suggest you contact HP Support for Service Options

Thanks again KT. Tried online HP Sustomer Support but they do not recognize product # GM757AA. I guess the HP w2207h monitor is too old, and I will need to buy a new one.
