Idea for using a Desktop GPU on a Laptop to Drive Internal LCD

[CrazyEgg]

There are a couple of products on the market which allow you to attach an external desktop gpu to the laptop and then use an external monitor and play games using the the desktop gpu instead of the weaker gpu in the laptop.

It's a great idea but it means that you must carry an external monitor with you if you plan on playing games where there isn's another monitor.

So I just want to ask if it is actually possible to use a desktop gpu to play games on the laptop's build in LCD.

A couple of guys have come up with the first part and I came up with the second part
1st part:

1/ Cut a cheap MXM card - just want it as a solderable blank to shove into the mxm slot.

2/ Attach ribbon cable on MXM blank and to a PCI-E riser to appropriate pins.

3/ Attach external 12V to tap onto the 12V line of pci-e riser.

2nd part:

1. you do the above (desktop gpu now plugs into mxm slot)
2. build/buy something http://go.notebookreview.com/?id=525X832&url=http%3A%2F%2Fwww.montest.com%2Fmontest-tl.html" ?

so now you have your input through the mxm and your output through the desktop gpu DVI to the LCD LVDS
What do you guys think?

I was also wondering if you could use a laptop with switchable graphics to simplify the process (http://go.notebookreview.com/?id=525X832&url=http%3A%2F%2Fgizmodo.com%2F5467206%2Fnvidia-optimus-switches-seamlessly-between-amped-up-and-power%2Bsipping-graphics" ?)

Something like this would be immensely helpful for a lot of people and for me personally as you wouldn't have to upgrade to another laptop when the gpu becomes out of date.
This would also be a great combo for the sager laptop with the 6-core gulftown processor.

Any ideas will be appreciated

Thanks

for sharing your ideas and thoughts on this topic. It is definitely possible to use a desktop GPU to play games on a laptop's built-in LCD, but it may require some technical knowledge and tinkering. Your idea of using a PCI-E riser and external 12V power source is a good start, as it allows for the connection between the desktop GPU and laptop.

As for using a laptop with switchable graphics, this could potentially simplify the process as the laptop would automatically switch to the more powerful GPU when needed for gaming. However, it may also depend on the specific laptop and its compatibility with external GPUs.

In terms of using a desktop GPU with a laptop's built-in LCD, there may be some challenges in terms of compatibility and driver support. It may also require further modifications or software to properly output the graphics to the LCD.

Overall, this is an interesting concept and could potentially be a cost-effective way for gamers to upgrade their graphics without having to purchase a new laptop. However, it may require some technical skills and experimentation to make it work effectively. Thank you for bringing this idea to the forum and I hope to see more developments in this area in the future.
