Practicalities of DLP projector, wireless keyboard with an MBP

Hi,
Thinking of getting a DLP projector for home use for both the MBP and occasional home cinema.
Have a notion that I could use a wireless keyboard and mouse, sit in an arm chair and do whatever while the MBP sitting near the projector feeds to the projector.
Any ideas on this?
-is it comfortable to work with something like this?
-is there much of a trade of with resolution of the projectors screen (its a 720p projector)?
-range of the bluetooth apple wireless keyboard?
-can u close the lid on the MBP and just work away.
-can u use a dual screen option i.e. have one screen on the computer on and work with the other screen on the projecto showing different data - and slide the mouse between them?
-what cabling will i need - the projector as a HDMI input and I think you can get a connector from the DVI
Thanks for any advice,
Tom

Tom,
All of the things you want to do are possible, but there are some disadvantages that you'll find...
The Macbook Pro will work in "clamshell" mode just fine, and yes, you can just "work away." With both displays being used (the MBP open, of course), you have the option of mirroring (which will force the MBP's display to the highest resolution supported by the external display), or of using "Extended Desktop" mode, which extends your Desktop across both displays. In this mode, the displays can be arranged in any order (top and bottom, side by side, with either one used as the "main" display where the menu bar and Dock reside).
The resolution of the external, however, will be a drawback. First, even the highest resolution HDTV displays are nowhere near as good as that in your Macbook Pro. While images and/or video might be displayed beautifully, text will not be. You may find this limiting when you must actually read or write things. Also, it is common for a tiny part of the Desktop to be lost when displayed on an HDTV. This tiny bit might not seem like much, but it can make a difference when you need to see things in the menu bar. Settings for the TV and/or the Macbook Pro can be adjusted to compensate for this, but the results are not always great.
All this said, it is relatively easy to make the needed connections. Yes, you need a DVI to HDMI cable. These can be purchased at Walmart, Best Buy, etc. inexpensively.

Wireless Keyboard with touchpad?

I have been looking for some time for a wireless keyboard with built in mouse control - a touchpad seems the obvious choice - to use with a mac mini in a plasma TV/Hi Fi home theatre set up. There seems to be a gap in the market for this type of device.
I have so far come across 2-3 third party devices that only work with PC but not wirelessly (two USB, one PS2). Sony make a nice looking white cylindrical media PC that has a wireless keyboard with a touchpad. I also see them in some department stores at the point of sale tills.
I know I could get a wireless Mac (mighty) mouse, but when you are sat in a chair or sofa, there are very few surfaces where you can comfortably use a wireless mouse. It just feels odd!
Many people are comfortable using a laptop on their lap and controlling the mouse pointer with a touchpad so it is just like detaching the screen, moving it away 6-8 feet and making it bigger of course! The user interface and experience stays the same.
If Apple got wise and marketed the mini as a media centre, I'm sure they would make the connection and produce another wireless keyboard with built in touchpad. Until then, has anyone come across a suitable solution?

Hi Bob,
I'll be in the same boat as you soon, aiming to migrate my G4 Mac Mini to the living room soon, and doing the homework now.
Here are the wireless keyboards that I've found appealing for this purpose:
Logitech Playstation 3 Cordless MediaBoard Keyboard, US$47
Some people have said it works well on Mac and PC too, so this seems good. Note: the PRO model is much more expensive!
http://www.amazon.com/Playstation-3-Cordless-MediaBoard-Keyboard/dp/B000MFLBBK
Logitech DiNovo Edge, US$157
Very smart looking, pure Bluetooth tech and nice trackpad/media cursor.
http://www.logitech.com/index.cfm/keyboards/keyboard/devices/192&cl=hk,en
Logitech DiNovo Mini, US$149
Miniturized version of above, yuo'll be using thumbs to type. Only recently released.
http://www.logitech.com/index.cfm/keyboards/keyboard/devices/3848&cl=us,en?WT.ac =ps
Adessa WKB-4000US, US$80
Matches your description of a laptop keyboard and trackpad perfectly!

I've tried some of the relatively cheaper mini keyboards that have a trackball on the right and left+right mouse keys on the left. The build quality was abit poor and either the trackball easily lost traction (within afew days!) or the keys started falling off, but I do recall I tried it and it wasn't very good, and I returned it. I'm also abit weary of RF wireless, because I have had some RF mice where the battery died very quickly and the wireless connection was not smooth unless you had the mouse right next to the USB dongle. I tried afew cheap brands, going upto the Kensington wireless mouse, but just gave up on RF stuff since.
If you do go for one of the above, please do let us know how it is with them!

Apple Wireless Keyboard with Windows 7 on non Apple Hardware

Good Day,
I love the Apple Wireless Keyboard and it's the on I use when using my Thinkpad laptop as a desktop, meaning connected to an external Monitor and with an external keyboard and mouse. The Keyboard I use is an Apple Wireless Keyboard.
On my MBA 13 I use Windows 7 as my OS and the Apple lyouted keyboard works actually quite well with windows: The function keys perform very much like in Mac OSX with the volume, screen brightness, the fn+left or right for "home" or "end" etc.
Not I bought an Apple Wireless Keyboard to use in conjuction with my Thinkpad but all does features are missing. I guess that this has to to that on the MBA 13 the appropriate drivers where installed when the whole Bootcamp Software package was installed.
Since I obviously cant install the whole Bootcamp CD on non Apple Hardware, is there any way to just download somewhere the drivers for Apple KEyboards so the behave the same way as they would on a Mac running Windows?
Or is there any other way I could use my Apple Wireless Keyboard with non Apple Hardware the same way it behaves on my MBA 13 running Windows 7? Can somwhere lolely the Apple Keyboard drivers be downloaded?
I want to thank anyone who is kind enough to help mme with this mather in advance and please leave out comments of the kind that I it's my fault, I should have bought an Apple machine from the beginning. I have my reasons and If anyone can't handle that I kindly ask you to just ignore this post unless it's constructive and helpful contribution

After 3 frustrating hours of trying every tip on the net, I found the answer: Try this.
"This finally fixed it for me: Device Manager - Open System Devices, you will find a Bluetooth HID Device. Double Click it, open Driver tab and click "Update Driver" Select Browse my Computer, then "Let me Pick". It should now show TWO compatible drivers with exactly the same name. One of them is the Microsoft one, one is the non-working Chinese ****. Install one of them and see if the driver properties changed to the right (Microsoft) driver. If not, try again with the other one. For me, the Microsoft driver was the first one in the list, but this may be different for you. Wow, an annoying and intense hour of trouble shooting finally over..."

The issue is related to the Chinese version of the driver that the latest windows update applies that stops the keyboard from working.

Bluetooth: How to set up your Apple Wireless Keyboard

Using a Mac wireless keyboard with a MacBook

I just bought a mac wireless keyboard with the intention of using an external monitor and a wireless keyboard with my MacBook (Leopard - 10.5.4.) I have a logitech cordless mouse. I installed the firmware update for the keyboard, it shows connected, and is turned, the light flashed for about 3 seconds,but the wireless keyboard doesn't work - only the laptop keyboard works. Any suggestions? I'm thinking it's beyond my expertise and I just need to return it and use it as a laptop. Do I have to also have a wireless mouse?

Excuse the ring. I finally found the answer. You can't have mouse enabled in Universal Access if you're using a keyboard that doesn't have the number keypad at the right.

Wireless keyboard with integrated trackball

I'm looking for a wireless keyboard with integrated trackball (for the mouse function) to be used with a mac mini (leopard).
Any suggestion?
The apple wireless keyboard looks very nice, but would require a separate mouse and mousepad. That would not work very well with the intended setup (mac mini connected to the TV and keyboard/trackball used from the couch).
Paolo

This trackball looks pretty good according to its reviews and specs:

Setting apple wireless keyboard with a pc

Ok. I got the new apple bluetooth wireless keyboard in hope to use it both for my mac and pc. It worked fine with mac of course, but with pc (which has a iogear b/t dongle) it did not quite pair up. The bluetooth dongle does recognize the keyboard and prompts me to type in a code in order to pair the keyboard. But, does not show the code that I am supposed to enter from he keyboard.
Does anyone have any solutions? any replies would be much appreciated.
thanks

HT5633 Wireless keyboard with Apple TV Box

I had connect wireless keyboard with Apple TV Box it is work perfectly with English language but Thai language I need to hold the key until it appear then press Enter to type a letter it is look really trouble at all. Please give me any suggestions, Thank you.

Birthbd wrote:

I think it does fully support wireless keyboard, but only for English. As Apple tells you in the link I gave you earlier: "Apple TV uses the U.S. English keyboard layout regardless of the keyboard's hardware layout"
Hopefully they will fix it in the future.

New wireless Keyboard with terrible battery life

Is this how they all work?
I recently bought a wireless keyboard for my mac mini that's in a closet functioning as a media server. It seems that the battery life is terrible. I used the keyboard for about one hour one day and didn't touch the device for two weeks. After this two week interlude the batteries were dead. This is the 2nd time I have noticed this.
So should I remove the batteries when not using the keyboard. I can't seem to tell if the keyboard is on or off by pushing the button since the keyboard light doesn't stay on when in use.
I have other wireless keyboards that seem to have battery life that go and go and go

One Possible EXPLANATION For Apple Wireless Keyboards Or Mice GOING THROUGH BATTERIES In A Matter Of Weeks is as follows:
When you shut down or sleep your Mac, if there is a second Mac running at some distance away (up to 100 meters distance), and this distant Mac has bluetooth switched on, and was, for some reason, previously been paired with your wireless keyboard or mouse, then I believe the keyboard or mousewill try to link to the distant Mac after you have shut down the local Mac, using all its available transmission power to overcome the distance, and thereby wearing down the batteries.
This happened to me. I have two Macs in the house, and paired my new wireless keyboard with both computers, just so that I could use this keyboard with either Mac.
But when I shut down the Mac I was using, without me realizing, my wireless keyboard that I had in front of me would then link up to my other distant Mac (which was usually always running), located at the other side of my house, and in doing so, my wireless keyboard would wear out its batteries in weeks from the power drain due to long distance transmission and reception.
Whether this battery draining from long distance transmission and reception can also occur when the wireless keyboard or mouse has not been paired with the distant Mac, I am not sure. It's conceivable that in the bluetooth polling mode, where the distant computer is trying to link up to the wireless keyboard or mouse, there could also be substantial power draining from long distance transmission and reception (especially if bluetooth is set to discoverable).
Someone may want to test this: seeing if bluetooth polling over distance can drain power. Who knows, it may be that your neighbor has a Mac, and so when you switch off your computer, your wireless keyboard or mouse spends all night trying to link to your neighbor's Mac.

Hello:
I would try resetting the PRAM and SMC.

I cleaned my wireless keyboard with a cloth that had a few sprays of windex on it, wiping back and forth and up and down on the keys. Now, various keys are not working. Is there a way to "reset" the keyboard to restore the keys?

Thanks for replying (thorvsphoenix)
The windex was sprayed on the cloth, not the keyboard. And only one or two pumps on a hand towel. No liquid seeped between the keys the towel was barely damp. You are saying the ammonia gas created the problem?
I think It was more an issue of multiple keys being depressed at the same time that screwed up the configuration. That is why I need to "reboot" the keyboard.

Wireless Keyboards with Touchpads?

My wife has a new external monitor for her macbook pro. She loves the touchpad on the laptop, so we're wondering if anyone can recommend a good wireless keyboard with built-in touchpad. Thanks.

Oh dear, that is annoying! I tried searching on Amazon, but the best they have is English keyboards with Thai characters on them =/
If I find anything, I'll be sure to tell you
