  • Hi, I have a Windows 7 Compaq Presario CQ61 with AMD M880G withi ATI Mobitility Radeon HD 4200. Last night I tried to connect my laptop to my HDTV. Now, I know I was very close, because I had it on the right input and I did something (I don't know what), it sent the signal to the TV, showing half of the image from the laptop, the rest looks as if a TV cable wire wasn't hooked up properly. So I'm not sure what the problem could be. Help would really be appreciated. Thanks in advance.

Does your tv have just the one rgb set of inputs and are the cable plugged into all the same input, then when in that input on the TV have you played with any resolution setting within the TV? Also have you set up the laptop to extend it's desktop to the new seen monitor/generic TV.

There are two sets of inputs for rgb and none of them made a difference and they are plugged in in the same input as well. Now, about the resolution, I didn't really configure anything, because I wasn't sure how that worked. But I'll give it a try.

As for the extend it's desktop to the new seen monitor/generic TV, I had been using "Projector Only," could that have been the problem?

what kind of cable or adapters are you using?
VGA won't go straight to Component.

I'm only using a VGA to RGB cable. I mean, I almost had it last time, some images were shown on the TV but it looked really bad. Now, nothing's showing up, I don't even remember what I did before. Another thing, what is this "Generic non-Pnp monitor"? Because it just showed up, is that my TV by any chance? Sorry for all these questions, I'm kinda new to this stuff. lol

I'd like to try this along with you. Given my computer and my TV interface, it all looks as simple as a single cable.

My concern: Do I have a cable length limitation to deal with?

OK! I got most of it on the tv, but why does it keep flashing so much?? I'm getting close now, do I have to configure something on the tv, or does this have something to do with the resolution on my laptop?

Great. Fifty foot is far more than I would need. I could make the connection, without relocating any furniture, with about a 25' cable.

Thanks for your response.

I would think that a fifty foot cable is the problem. Keep all cables as short as possible and to expect the signal both audio and video to not have interference and or have huge resistance over such distances would be my first concern. Move your laptop right next to the TV and run a standard 1-2 meter cable and see the difference.

Here's some miscellaneous help for you. I think if you read through the material it will lead you to the resolution of your problem:

Connect your computer to a TV from Microsoft
How To Connect Laptop To TV | Geek with Laptop
What you'll need if you have an HDTV – from Microsoft
What you'll need if you have a standard-definition TV – from Microsoft

TV – CONNECT TO COMPUTER – HDMI CABLE
This is your BEST option, if your laptop has an HDMI output and your TV has an HDMI input, then all you have to do is connect your laptop and your TV with a good quality HDMI cable - 1.1 or better. (See CHART at bottom of post.)

TV – CONNECT TO COMPUTER – RGB IN
If your TV has an input that is [RGB IN], (that port looks just like the port that you use, to add an external monitor to your laptop) all you have to do is connect your laptop to that port with the proper cable -- one that has an RGB connector on both ends. (They are usually blue color.)

TV – CONNECT TO COMPUTER – S-VIDEO OR VGA OUT
You can use either the S-Video out or VGA out connectors on your laptop to connect it to your tv. But you'll also need to use a male to male 3.5mm AUDIO CABLE from the headphone/speaker port on your laptop to the audio input of your tv to get sound from it.

TV – CONNECT – ‘RGB IN’ SLOT – FOR COMPUTERS
The RGB In slot is specifically for the PC. (TV's from LG have "RGB" inputs as well as DVI, AV (the old fashioned Video In), analog LH and RH sound, Component, SCART, and HDMI.)

To use your laptop with the tv as a monitor connect the VIDEO MONITOR cable from your PC to the TV, then on the TV go to INPUT, and select the RGB input VIA THE TV’S REMOTE. No need to disconnect the computer -- the remote will "flip it" instantly. LG did their homework on this function properly. The LG TVs work an absolute treat when you want to use them as PC monitors as well as TV sets.

TV –DISPLAY + TUNING PROBLEMS

Getting the best display on your monitor – from Microsoft
How To Connect Laptop To TV | Geek with Laptop
Troubleshoot problems with watching TV on your computer (Vista link)

Press, say F5, (or other key --usually marked) to switch off the laptop’s own monitor and then you can use the maximum resolution your video card and monitor are capable of. If you have a high resolution video card you can connect the HDMI card to the TV giving fantastic HD quality video too.

If the screen looks stretched, or part of the screen seems cut off, you probably need to adjust the screen resolution in Windows. Or, if you can't see Windows on your TV, you might need to reconnect the computer to your monitor and adjust the screen resolution before you connect to your TV.

And try this: After you have connected it, go to Control Panel, Display, Adjust Resolution, and then click Detect. The TV should show up on the right.
