[jojo6]

Hello there!Guys could you please help.I'm not very good at computers.I have a laptop SONY VAIO ,CPU Intel Core 2 Duo Processor T8100 ENHANCED INTEL SPEEDSTEP 2.10 GHz,memory 4GB/Go DDR2 SDRAM,grafics NVIDIA GeFORCE 8400M GT GPU,BLURAY COMBO DRIVE,1080p.When i bought the laptop i had vista home premium and now i bought the windows 7 home premium wich came with 2 cd(32bit) or (64bit).Before when i had the vista i could connect my hdtv wich is a sony 40inch thru the HDMI and it would recognise it but now when i install windows 7 it doesn't.Oh by the way i did update the driver and i install the 32 bit version.I'm not even sure if i can install the 64 bit.Is not even working with tv out ( svideo ).THANKS

1) Did you install x86 or x64 version of 7?

2) What outputs does your laptop have?

3) What inputs does your tv have?

The best option would be hdmi.

 

[jojo6]

My laptop got the hdmi and s-video and tv the same
i install the 32 bit version

 

[Frostmourne]

Then connect an HDMI cable from your laptop to your TV, and adjust any settings.

 

[jojo6]

I did and i adjust the settings several times but it doesn't recognise the tv.it's just show the main display.i pres detect and nothing.as i said when i had the vista it was working but now i dont know what to do.

 

[Frostmourne]

What is the resolution of the tv and your laptop? Go into the gpu control panel and look at a setting for tv's.

 

[jojo6]

What is gpu.how do i get there.what i did was go to control panel- adjust screen resolution and then i changed the resolution to several options still not see second display.just display 1.i tried detect but nothing

 

[jojo6]

RESOLUTION ON THE DISPLAY IS 1280 BY 800 TRUE COLOR 32BIT DEFAULT REFRESH AND ON THE HDTV IS 1080p FULL HD.

 

[Frostmourne]

In control panel look for nvidia control panel, plug in the cable and look at the display options. GPU is your graphics card. You might have to lower the resolution of the TV. Check the control panel.

 

[jojo6]

I did look in control panel for nvidia control panel and i couldn't find it.

Look in the TV's menu settings to ensure that nothing needs a reset, or whether the TV needs to scan for fresh input sources. If you can't detect the HDMI signal then try and test the output on another HDMI display.

At least if you can deduce where the problem lies you can better tackle it.

Hello jojo6, welcome to Seven Forums!


R click an empty spot on the desktop and select screen resolution and post a snip of that here, like this.

NVIDIA should have a tv display setting.

 

[jojo6]

I have an option on the tv under set up hdmi connections that sais device list update.i did what you said and the tv could not detect any other devices

 

[jojo6]

I could not get to the nvidia control panel or maybe i don't know how.

 

[Frostmourne]

Search for nvidia in control panel.

 

[jojo6]

Ok i got to device manager-display adaptors-standard vga graphics adaptors but nothing about nvidia.

shot in the dark
1: right click anywhere on the desktop (just not on an icon or gadget)
2:from the menu that appeared select "screen resolution"
3:in the window that appears, next to multiple display click on the pull down tab try selecting "extend these displays" or " duplicate these displays" see if any of that works for ya

I Have the same issue but also have a resolution to this, restart your computer while the HDMI cable is plugged in. this worked for me, but as a previous Vista user this is very annoying as it is no longer as simple as plug and play. This may be a video driver thing with nvidia and not just windows seven.

Here is some much better news (I hope this will work for you too). The previous drivers I was using is provided through windows updates, the version number is 186.31 for 9800m GS. I went to Nvidia web site and used their version which is 186.81. Now plug and play works perfect with an HDTV. You will have to re-run the WEI to to turn transparency back on.
