HP ENVY 15t-3000 to sony kdl-26m4000 via HDMI

[lidodraco]

Hey i just got my hp envy 15t-3000 today and i tried to hook it up to my sony kdl-26m4000 lcd tv via a hdmi cable. my computer detects the tv set is connect but on the tv it says that there is no signal.

you also need to change your computer's video output to hdmi. I don't have a Envy laptop, but in general it is usually fn and F4 key to change video from laptop screen to hdmi.

Change your sound output if you want sound from your TV.

hope this helps.

yes i have tried, pushing fn f4 and there is still no signal. i checked the input on the tv makeing sure that its plugged into hdmi 1 to match with the input.

First of all, I would check to make sure the hdmi cable and hdmi port of the TV works by plugging it into a DVD/blue ray player or any known good source of hdmi device.

If the TV's hdmi input works, then when you press fn & f4, does the internal display of the notebook blanks out? try lowering the resolution of the computer to match the TV, sometime if the screen resolution is set too high.  the TV might have problem handling it.

I have tried all you have mentioned above. I know the cable works because ive hooked up my mac book pro via minidisplay > hdmi > tv

Can you extend the display using the procedure in this youtube video?

I want to check to make sure the PC can detect and output to the TV via hdmi.

I have done everything just like the video, as i had stated before my computer does detect that the tv is plugged in. But the tv, set on hdmi input 1 still says no signal.

Please correct me if I am wrong, I presumed you are running Windows 7 64 bit. I would try to download and install the latest graphics driver from www.hp.com. The latest driver has support for switchable graphics, Catalyst Control Center and hdmi audio driver for supported notebook .

i have, ran things back and forth with the drivers, and even disabling the switchable graphics on the bios. I have came to a conclusion that my tv set is just to old to handle the a/v signal that the laptop is sending out via hdmi. thanks for your help i greatly appreciate it.

Perhaps one last try before giving up? On you computer, make sure the output to the TV is not greater than 1280 x 720 resolution and a monitor refresh rate of 60 hertz.
