Brightness when plugged into a LCD projector

How do I adjust the brightness of the image when projecting through a LCD projector? As soon as I connect (through DVI port) to a LCD projector (as a professional speaker, I connect to different LCD projectors almost on a daily basis) the Brightness adjuster in System Preferences-Displays disappears.
I've always blamed the poor LCD projectors until last week when I got the same problems with my Macbook Pro but not with someone else's Macbook (not a Pro). Their settings must have been higher than on mine. I even tried putting the brightness on my Macbook Pro to maximum before plugging in to the LCD projector, but this made no difference.
A resolution of 800x600 (stretched) always seems to be auto-selected by my Macbook but changing the resolution doesn't seem to make a difference
Hope someone can help - this is reflecting badly on Macs!
Thanks
James

You might also try going to System Preferences/Displays, choose Color and choose a different display profile. (The projector is supposed to tell the mac which profile to use, but sometimes it doesn't quite work.) You might even choose calibrate and produce a new profile. Adjusting the "gamma" of the profile may brighten the image.

How can I stop the display dimming when plugged into a powersupply. Cannot read playlist in car using music player.

My new ipod seems to dim after a short time, even when plugged into a power supply, unlike my previous ipod, which used to stay illuminated
when plugged into the car stereo and external power
Now in order to see the playlist I have to swipe or touch the home button, using the music player. However using a GPS app, the screen stays
fully illuminated......as it should!
Is this normal now for playing music?
Also, the new grey on white menu display for music is very hard to read in the car in bright daylight.......unlke the old white on black. Nothing I
can do about that sadly except complain to apple directly :-(

Hi Diavonex. Yes I was aware of this option.
Subsequently I have done a litle research and downloaded a music app called "Track 8" which has a much clearer interface (larger type) and the abillity to change the background colour to dark or light.
This is much more readable in the car in bright light, and much better at night too.
You can also turn off auto-lock within the application, which is great, as it doesn't affect other apps.
Although this app is really only an interface sitting on top of the music app, it offers a much better experience
in my opinion that the stock player which seems to have devolved rather than evolved.

There is a hardware problem. Whether it's worth it to you to have no working phone for 2 months until you can update vs paying for replacement/repair now is a question only you can answer.

I have an Retina display MacBook Pro with HMDI out port. I also have an HDMI to Component cable with Audio Plugs. How can I get HDMI out to work with this cable when plugged into the Component and Audio ports on my TV?

Will not work. To my knowledge, dual converting like that isn't supported. The Mac must detect the connected video output device and that sort of info cannot be done across an analog component uni-directional connection.

Decided to update iphone 4 to ios 5.1 and mid update it froze and the screen is black. Phone does not respond to any combinations of home and power buttons, when plugged into computer it does not see it is plugged in, any ideas?

Decided to update iphone 4 to ios 5.1 and mid update it froze and the screen is black. Phone does not respond to any combinations of home and power buttons, when plugged into computer it does not see it is plugged in so I cannot restore or anything. Looks like the screen is on it's just unresponsive and black obviously. Has anyone had this problem? I was updating via wifi right in front of my router and my computer.

Spoke to a "senior advisor" in the Apple TV department. Her suggestions: change channel in router to minimize/eliminate wifi interference from other users; move router away from any metal - i.e., DVD player, phone modem, etc.; keep router away from wireless 2.4 gH phones, which are "notorious" for crashing wifi routers. So she confirms that the problem is one of connection to router suddenly dropping out.
My own feeling is that none of these fixes will do the trick, because it seems pretty clear that there is a hardware component here - the timing of the drops seems like an overheating issue. It takes 35-40 minutes for the box to warm up enough for the first drop; then each consecutive drop happens quicker than the one before, as it heats up more. Each time it drops, its tiny brain gets a little more scrambled; last night it finally wouldn't start up again at all.
My suggestion is that everyone who is experiencing this problem, please call Apple tech support and ask to speak to a senior advisor in the Apple TV department. Make them aware of this problem!

My Ipod touch will only work when plugged into a itouch radio. When I take it out, it goes blank. Why can I do?

My Ipod touch will only work when plugged into an Itouch radio. When I take it out of the charger, it goes blank. The battery shows fully charged. It appears that the battery is no longer charging. What should I do?

Try a reset: Hold the home and power buttons at the same time until the Apple boot logo appears. No data will be lost. If that fails, the battery may have gone kaput.

BSOD when plugging into Dynadock U3

Hi There,
We have a wide number of Toshiba Dynadock u3.0's working with a number of Sony Vaio Laptops. In the main they have worked pretty well, and have improved over time as new releases have come out.
At the moment we are rolling out the new Sony Vaio Pro laptops, and Dynadock is almost essential for users because the Vaio Pro's do not have an ethernet adapter. We are also downgrading them to Windows 7 from Windows 8 as we are not ready for Windows 8 on a large rollout, and holding off till 8.1 goes live.
We have had a couple of blue screen of deaths on 2 Vaio Pro's when plugging into the Dynadock. Both have the latest dynadock drivers, and we have obtained the memory dump for the machines. Before they were plugged in, they were on the WLAN in the office.
The other half a dozen devices we have in use at the moment have not yet reported this issue, and the BSOD has appeared on these two devices only once each, but I was asked to report this issue on these forums to just confirm there is no obvious issue with the Dynadocks.
In the meantime we have 3 other Vaio pros which are being tested and have not yet experinced the same issue.

Turning on the laptop when plugged into the dynadock, and he gets a BSOD. I've pasted the bugcheck in below. We are in the process of uninstalling and reinstalling all the drivers, and replacing his dynadock with a known good one to determine if the issue resides with the laptop or not.

I'm having the same problem. I'm using a new shuffle usb cable in my 2nd generation shuffle and nothing shows up on computer. I'm wondering if the dock for the second gen is different than the new usb cable direct into the 2nd gen shuffle. I don't have a dock for it. Before I buy one on ebay I hope someone can assist.

IPnone 4s not recognized by Envy dv7-7333cl rnning Windows 8 when plugged into usb port

Laptop does not recognize iPhone 4s when plugged into any of the 4 usb ports. All usb drivers are up to date. All Win 8 and HP udates have been installed and are current. Ports do recognize memory sticks so seem to be working. Is there a special driver needed for iPhone?
This question was solved.
View Solution.

Hey texasbootz,
I'll have to get you to answer a few questions to understand what is going on exactly:
When the iPhone is plugged into the notebook, does it charge?
When the iPhone is plugged into the notebook, does it show up in device manager?
Is iTunes installed?
If it is not charged when plugged in, it is possible that the cable you are using isn't functioning properly, and you may need a replacement. Or, the iPhone itself is having some issues.
In any case, since other devices are working in all of your USB ports, it is possible that its either a software issue (with the iPhone's drivers) or an issue with the iPhone case. You'll have to contact Apple for support on either of those issues. I'd suggest trying to re/install iTunes, see if that fixes it, then to contact Apple.
Hope this helps!
I am an HP employee.

Iphone 3g not recognized by computer(s). Windows 7. Charges when plugged into wall, but not PC's. Also not listen in Device Manager. I have hard reset/soft. reinstalled itunes after clean wipe. went through services... help! Windows 7

Hello all. My system is Windows 7 64bit. In the past my phone worked just fine, plug it into a usb slot, synced up, updated... but for months now it has not worked. Other Iphones will not work on this PC either with their corresponding cables. But my Iphone will also not work when plugged into other computers.. it will not show up at all.. no charge.. no itunes... no drivers show up in Device Manager. My phone works just fine when plugged into the wall with it's cable.. charges fine everything works.. but it will not charge when plugged into a computer.
So far... I have uninstalled everything related to apple... ran ccleaner.. fixed registry errors. Reboot PC, reinstall all itunes and apple components (all latest software) and nothing.
I have gonet o services and stopped and started apple mobile device. It is set to automatic.
I have hard reset the phone and soft reset it.
The cable obviously works. The Phone works when plugged into the wall.
Other Iphones will not work on my pc, nor will my iphone work on theirs
I have disabled windows firewall along with my Comodo Defense Plus and it's firewall. I have disabled my AV. I have scanned with ad aware plus, Avast, ran hijack this and fixed registry errors. Ran Ccleaner.
My device manager does not have anything related to apple in it.. I have no idea why. My Device Manager has no portable devices detected at all and does not recognize anything related to the phone.
Core 2 duo 6600
2gigs of ram
Windows 7 64 bit
I have checked all the tech support stuff I can find. I am desperate. Apple will not help me on the phone without charging me 30$.

Also.... my phone works and can do everything fine when not plugged in.. I just can't get my computer or others to recognize the darn thing when plugged in!

Nonsense, and very misleading advice. I've updated iPhone 3G, 3Gs,and 4 through itunes many times, never had a problem once, not with one single update in nearly 5 years of iPhones. Of course, I've never jailbroken my phones either. Hack your phone and have update problems? I've got news for you, the problems are not a result of iTunes or Apple's updates.

Dude you have a jailbroken phone as stated in your first post, no need to do a second post.
As per the forum term of service you can't get help here. Use google.
that's the downfall of jailbreaking your phone.

How come my Ipod Touch will only charge when plugged into a computer and not a docking station or wall socket?

My IPhone works with both the charging USB cable as well as the wall socket and docking station. Additionally, my IPod used to charge using both the wall socket plug in and the docking station. My IPod will stay play music when plugged into the docking station, but won't charge. Further, when I plug my IPod into my computer all it will do is charge and is not recognized by ITunes. I have done both a soft and hard reset.

If the iPhone has no problem with the same cable then
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

ITunes no longer recognizes my iPod nano 5th gen. When plugged into macbook usb it appears as my iPhone. Previously both devices had individual identities. Have reset iPod and turned macbook off/on.

Hello BPeery,
I would go through ALL the steps here:
iPod not recognized in 'My Computer' and in iTunes for Windows
Let us know how it goes.
Hope this helps.
