Have TV Questions? Ask a TV Technician
Hello and thank you for contacting JustAnswer, a third-party paid expert support site. My name is XXXXX XXXXX I'd be glad to assist you with your issue.
This usually means that the resolution you are trying to use on the TV is outside it's rage.
What version of Windows are you running?
Windows 7, I just bought my Lenovo at Best Buy
Ok, thanks. Right-click on your desktop and choose Screen Resolution
In the image above, you should see two boxes (1 and 2)
ok, then what?
I see the 2 boxes ....
BeBoo wake up lol....
still waiting for your instruction
Sorry, I had to step away
ok what next?
Ok, so one will be your monitor (usually '1'), the TV will be the other. Choose the second monitor (box) and change the resolution. Click Apply and see if the TV shows an image. Keep trying this until the picture shows up and looks good. Start at the top and work your way down.
Try choosing a "Recommended" if there is ne
no TV image shows , just invalid format on lower left hand corner of TV.
1024x768 should definitely work
On the display drop down, you are changing the one for the TV, correct?
If it still doesnt work, try clicking Advanced settings, then the Monitor tab. Try changing the refresh rate.
still nothing....on the TV remote in input is on HDMI 1 correct?
If that is the input you are using, yes.
Check the back of the TV to make sure you are in HDMI 1
Perhaps try a different port
I have already tried everything you have suggested.
Ok, in that case, I will opt out and allow another expert to take a look.
Actually, just a few other quick ideas...
In that same window, the last drop down (I can't remember what is it labeled off the top of my head), is it set to Extend these displays?
Does toggling the Fn + F7 keys have any effect? What model Lenovo do you have?
So, neither the VGA or the HDMI work on the TV?
