Hello all... Here is my dilema...


When I connect my laptop via HDMI to my HDTV the laptop initially sees the tv but then loses it when I turn the tv on... if that makes sense???


I've updated the tv's firmware as well as made sure all the laptop's drivers are up to date.


Here is the equipment:


Dell Studio 1535 laptop running Win7 Home Premium

Philips HDTV 47PFL7403D/27


With the laptop turned on and the tv turned off the laptop sees Philips 105S (105S2) as the secondary display but when I go and turn the tv on the Philips 105S (105S2) disapears. What could the problem be? I'm stumped?


Any and all help would be appreciated... Thanks!!!

Check to make sure your output resolution on the laptop matches one that the TV can handle. Sounds like the laptop can no longer recognize the TV after it sees what resolutions are available.

Hi Andy... Thx for the input... I've already tried your suggestion but am still getting the same result.


I've been thinking that maybe Win7 is messing things up??? I wonder if reinstalling the OS would help. When the laptop was running Vista everything was working... The Win7 upgrade cause this with the Philips. My other TV's, a Sharp and a Sony work fine with Win7.


I've also tested the 4 HDMI connections on the TV to make sure they work.


This is the first time that I've had equipment "handshake" while off only to lose it while on... Weird???

I don't know if it will help but I think you're actually getting two handshakes - a default when off and a specific when on.


Reinstalls are usually painful, so I try to stay away from suggesting one unless there is a reason. I'd be more inclined to check the video driver first before doing any reinstalls.

Yes, Andy... It would appear that the unit is doing that... The computer first sounds when the tv is connected and then sounds again when I turn it on.


When I connect the tv (while off) the computer acknowleges the new device as 'Philips 105S (105S2)'... I've started to think that this may be wrong because my little research has shown that is an older model CRT monitor... I wonder if Win7 is sensing the wrong device???
