I just built a computer for my tv, and am trying to hook it up but am getting no picture let alone a signal from the computer. It was just built so nothing is installed including the os. I just wanted to see the motherboard screen for confirmation I did everything right. I reseated ram and video card. Do I need to plug it into a vga monitor first? Help me please

Here is build:

(Im using a cooler master cpu heatsink rather than the intel one)

Thank you for any help... I just wanna play my steam games and blurays in 50inch plasma.. is that to much to ask >.<

Sometimes a TV will not synch to the default frequency sent by the video card. Hooking up to a monitor then using the advanced section of the video driver to force a TV setting fixes that. If the monitor works then download most recent nvidia driver before playing with TV settings and see if the new nvidia driver detects the TV correctly (vs. the windows default driver). You'll also want the latest nvidia driver before you try to get sound thru the hdmi cable.

Hooking up to a monitor first also proves the rest of the PC is working.

Alternative is to pull the video card and listen for the beep code that means no monitor.

Aside: you should be hearing your disk drive spin up and seeing disk activity even if the monitor is not...

aside: nice balanced system. ORANGE case? cool.

Your CPU has built-in graphics. Have you tested to see if those are coming up as the primary graphics device? You may have to manually disable the on-board graphics if the system is having issues defaulting to the add-in graphics board. Or it may be a matter of going into BIOS and setting a different order for the system to initiate the graphics in, such as setting PEG1 as the first video device, so it looks to the PCIe x16 slot first.

You won't get a no-video beep code, as there are graphics on the CPU. Might be worth plugging into the HDMI of the motherboard, or perhaps there was a simple oversight, and you are plugged into the wrong HDMI out at the moment? :)

I have my computer connected to a 50" plasma. Setting up the HDMI required connecting a monitor via DVI first, disabling onboard video, and setting the audio device output to HDMI.

What's kind of a pain is if the video cards output does not synch with the tv, you will have to connect both the monitor and the tv at the same time. With both connected, right click to get to your nvidia control panel. Go to display/video & tv, and adjust settings as needed to make the display look good on the television. Once that's done, choose the tv as your primary display and disconnect the monitor. Aftwards go into the control panel and choose hdmi sound as your default playback device.

I'm not super familiar with BIOS or CPU built in graphics.. tell me more! I'm very new to custom computers. This was my first build.

Also I was plugged into the motherboard hdmi. There is only one hdmi out on motherboard and one hdmi mini out on gpu. There are multiple hdmi inputs in the TV.

On the other hand, if you pull out the add-in GPU, you should run just fine with the on-board graphics and be able to boot and make settings changes in your BIOS, which you will perhaps want to learn a bit more about, since you're doing the build yourself. :)

Read the section in your manual for your motherboard detailing the BIOS and settings. It may shed a lot of light on things for you, such as how you access it for your particular motherboard. Also, Google is your friend here too. There is so much useful information out there about computer BIOS settings, the only obstacle to your being very versed in it is your willingness to soak it all up. :) You don't need to become an electrical engineer or computer scientist by any means, but a good healthy knowledge about what's going on under the hood will help you be a better computer operator and give you a great appreciation for things. Building your first rig is a great first step.
