Couple things to be aware of:
1. The X200 is not available with a Blu-Ray drive. So, your HD content will need to come from somewhere else, such as downloading from iTunes. Alternatively, you can purchase an external Blu-Ray drive. (it may be cheaper / easier to buy a dedicated Blu-Ray player if that's the route you want to go).
2. The X200 only has analog audio output. The only surround you'll be able to receive is Dolby Pro-Logic, provided your source material has it encoded that way. You can connect your laptop to the receiver via a 1/8" to RCA adapter, available at virtually any electronics retailer. (Buy the cheapest one you can find) Connect the 1/8" plug to your headphone jack on the laptop, and the white and red RCA connections to any available input on the back of your receiver. (such as CD, AUX, DVD, etc.) Select that input on the front of your receiver and you'll hear the output of your laptop. Enable surround sound processing (pro-logic) on your receiver. Check the manual for instructions on how to do that.
3. Purchase a VGA cable (I recommend monoprice.com
). I suggest staying under 15' for optimal quality. Connect one end to your laptop, and the other to the PC-in on the back of your TV. Select that input using your TV's remote. (On my Sony, I press Menu, External Inputs, then PC)
4. Set up your laptop to use the external monitor. I suggest leaving your laptop off till you plug in the VGA cable. If upon booting your laptop is outputting to the TV display, usually a key combination such as Shift-F7 will enable it.
Alternatively, your TV has an 1/8" audio input jack that goes along with the PC input. If you've connected the audio out of the TV to your receiver already, the audio from your laptop can pass through the TV to the receiver. 1/8" cables can also be purchased from Monoprice.com
Let me know if that helps!
