http://community.acer.com/t5/Notebooks-Netbooks/Aspire-7720-split-screen/m-p/257296#M42059 <P>I have an Aspire 7720 laptop and the monitor is displaying horizontal split screen, where both sections display the same thing. Also, the whole monitor displays vertical <SPAN>dashed lines. I tried to connect a projector and the projector took no signal. I rebooted without removing the cable and then the projector took signal but the laptop’s monitor took no signal, it was totally black. What is wrong? Solutions?</SPAN></P> Thu, 26 Jun 2014 16:36:18 GMT doctorized 2014-06-26T16:36:18Z http://community.acer.com/t5/Notebooks-Netbooks/Aspire-7720-split-screen/m-p/257296#M42059 <P>I have an Aspire 7720 laptop and the monitor is displaying horizontal split screen, where both sections display the same thing.

If it does, there is a hardware problem and you may need repair.</P> Wed, 09 Jul 2014 15:37:55 GMT http://community.acer.com/t5/Notebooks-Netbooks/Aspire-7720-split-screen/m-p/263900#M42465 Acer-Blayn 2014-07-09T15:37:55Z
