Hi I have a scarlet ~40" LG lcdtv 1080p and I want to display what I'm doing on my lenovo T61 laptop on my tv. I have been able to do this with a regular old VGA cable however the highest resolution I can display it in is 1280x1024 because my laptop cannot itself display 1920x1080, which is the next higher up resolution accepted by my tv. Additionally it seems that regular VGA cables aren't able to transmit sound from my laptop to my tv.

I have been trying to research solutions for these problems online but I've been having trouble getting enough information as to what exactly I need to be able to display my laptop on my tv with 1080p and tv based audio. Could someone tell me exactly what cables I need and any additional requirements?

From my research I have found items such as the Mega-Cool [URL="http://www.dcemu.co.uk/vbulletin/threads/142650-Review-XCM-1080p-Mega-Cool-VGA-Box"]http://www.dcemu.co.uk/vbulletin/threads/142650-Review-XCM-1080p-Mega-Cool-VGA-Box[/URL] that say they can upgrade your display resolution to 1080p. First, does this work hooking a laptop up to a tv display. Second, does the input resolution matter (will it be lower quality output on the tv if I use a lower input resolution on my laptop)? Third, does the quality of the VGA cable hookups for it or other types of cables have an impact on the quality of the output display (what is the ideal cable to use)? Fourth, is the converter necessary at all? When I googled VGA cables some were called 1080p VGA cables. Does that mean they convert the signal to 1080 automatically or that that is the best possible output that the cable can provide?

I've also come across sites advertising VGA cables that come with audio connections to hookup audio to your tv. [URL="http://www.hdtvsupply.com/sca10te.html"]http://www.hdtvsupply.com/sca10te.html[/URL] Will this work for me (Do I have the needed hookups for my laptop and tv and would that audio hookup from the link work? [see my pics])? If this wont work for me is there another way I can get my audio from my laptop to my tv?

Here is a picture of the back panel hookups for my tv:

I see that there are additional hookups besides VGA. would any of these others be compatible with my laptop and its hookups (like a splitter cable with vga one end and component on the other...etc.)?

Here is a picture of the side panel hookups for my tv:

Here is a picture of the hookups for my Lenovo T61 XP laptop:

So in summary:
[LIST]
[*]Is the Mega-Cool what I need to display my laptop on my tv and convert the signal to 1080p?
[*]How do I get audio from my laptop to my tv?
[*]What cables do I need (do i have the right hookups on my laptop and tv [and what is the best and most reasonable cable in terms of quality and price])?

Thank You in advance for you help. Any and all input is appreciated. Sorry for the lengthy post I just wanted to make sure I put in all the needed info.

I found a way to convert my tv input signal to 1080 via my video cards Nvidia control panel. Hurrah! More real estate. Thank you for all your help guys.

The Mega-cool unit converts component video (RCA jacks) to VGA. It does not convert resolution and will NOT solve your problem.

The laptop does not send a audio signal to any of the pins in the VGA jack. So a special VGA cable will not help your sound problem.

You are stuck with the highest video resolution that is compatible with both units. (1280x1024).

You need an audio cable that connects the earphone jack on the laptop to the RGB audio input on your TV. It looks like it's located right next to the VGA jack.

Good Luck

are you sure it wont convert the input signal to 1080p? It seems to imply it will and if it doesn't what about this converter box? It surely seems to indicate it can do 1080i conversion: http://www.allaboutadapters.com/

That unit is different from the one you had in the first post. The second adapter does do conversion.

I would only buy this if there is a good return policy. You might not be happy with the results. The hardware will be creating pixels and you may not like the results.

cool, so going by the fact that it creates more pixels in the signal I'll have more space to display whole pictures and movies w/o changing their scale/zoom % right, that's why i really wanted the higher resolution :D? Also did you see on there what the converter box output to lcdtv input cable format was. I think in the picture it was a component cable on one end and vga on the other (vga/component). It doesn't really show in the pic (http://site.allaboutadapters.com/webgraph/AV7-Application.gif) if the vga/component cable or a vga/vga cable was going to the computer monitor or the tv. That won't cause any problems with the original vga/vga cord going from the laptop to the converter right (cuse that's what the converter is supposed to do)?
