Lenovo Desktop 700 25ISH to TV via HDMI No Signal

I just bought a 700 25ISH 90ED desktop and I am trying to use my television as the monitor. The TV is brand new, only two months old. I am attempting to connect them via HDMI cord but no signal is coming through. I tried connecting my laptop to the TV using the same cord and it works fine so the TV, and the cable are obviously functional. But the Lenovo desktop will not come through, all I get is a no signal message on my TV.

 

I thought that the HDMI port on the desktop was damaged or not functional so I took it back to Best Buy and exchanged it for an identical model. But the same issue is happening.

 

I ran through all the basic checks, everything is plugged in and on the right TV input setting, tried using all of the HDMI ports on the TV (which all work with other devices), tried swapping around the cord ends, and the computer is plugged in.

Hi samwhys , 

 

 

Welcome to the Community Forums.

 

Based on what you have described , cord and monitor all ok with the HDMI connected with your laptop. 

Back on the 700 25ISH rear ports, would you have an additional graphics card installed as on the image ?

Will it say no image even when connected on the bottom HDMI port? What is the machine number for the PC?

Do you have a different HDMI cable available to test also ?

 

Update us how it goes?

 

 

Regards

HI Robertrey , 

 

 

Welcome to the Community Forums. 

 

The hdmi on the upper left is suppose not to work if there is an add on card. 

Default would be using the add on card offered as shown on the bottom for optimal display performance.

 

If the video card broke, you may still see the display using the upper left HDMI since it's buit in on the motherboard.

 

Hope this answered your query.

 

 

Regards

Re: Lenovo Desktop 700 25ISH to TV via HDMI No Signal

if you have speakers plugged in and the tv switched on and plugged into the gfx card bottom ports, when you get the windows login/boot sound (the chime) press and hold windows key then press p twice (there is 4 options when doing this and the p press twice should duplicate the screen) hopefully this will help you

I bought this computer in order to extend my dektop...are you saying that even though there are two video ports, only one works?
