I'm no longer able to use the projector VPL-ES4 with win7, he accuses error frequency
I'm no longer able to use the projector VPL-ES4 with win7, he accuses error frequency.
Working at a university here in Brazil Unicamp.
Here we have several projectors model VPL-ES4, we were using this projector with win7 however a few days they all stopped to show the image of computers accusing problem in frequency, we made all the alternatives so that One can be reestablished TRANSMISSION signal however all were in vain, reading in many forums found equal to our cases and the solution presented was to use a computer with win98 and it really worked, but with the end of support for this version of the system we are failing to use it, I wonder how we can solve this problem and why even this ocrrendo.
I thank you in advance for help and attention

Here's what you can do. Fully remove the xorg.conf file. Regenerate them using nvidia-xconfig, Open the nvidia's GUI as root and just click "Save configuration", or something among those lines. Google your monitor's manual and find the RIGHT vertical and horizontal sync frequency ranges. After setting them in your xorg.conf log-out and log-in again. Go to the nvidia settings gui, you should be able to use a higher resolution.
I've tried this a few times, but always end up with a "Signal out of range". I think the trick is finding the correct ranges. My monitor is a Soyo Topaz S 24", and I can't find any official manual or specs online. What I have found is this:
http://www.thinkcomputers.org/old/index … ews&id=733
That review indicates:
Frequency: Fh: 30 kHz - 80 kHz; Fv: 50 Hz - 75 Hz
So I set:
HorizSync 30-80
VertRefresh 50-75
Signal out of range, which is annoying because in order to fix it I either have to reboot using a live CD, mount the drive, or ssh into it. Whoever started the trend of disabling ctl alt backspace to kill an xsession is not my friend...
Some other forum posts about this monitor indicate that there may have been two variants, but I can't find a different set of specs.

No matter where I go, as soon as I turn on the Internet on my new Mac Book Pro, everyone else is no longer able to use the Internet. How can I fix this? I received it as a gift for college, but its hard to do research when everyone constantly yells at me to get off because they can no longer continue what they're doing.
<Edited By Host>" how can I sync my iphone to my mac book without losing all the music and pictures on it?"
You cannot. Copy everything you want form the old computer to the new one, then sync it.
it basically says you have to erase your iphone to sync to a new itunes!
Correct Iphone will sync, or manually manage, with one and only one computer/library at a time. Syncing, or manually managing, to another will indeed erase the current content. -
In camera raw, I am no longer able to use the adjustment brush. This is a recent phenomenon.?
In camera raw, I am no longer able to use the adjustment brush. This is a recent phenomenon.
Well, it worked fine for me as well for the past couple of years. I had not had any problems using it for the past few years. I use a Mac OS X Yosemite. As far as I can tell nothing had changed. I had not added any new updates, and a week ago the adjustment brush in camera raw simply ceased working. Everything else in camera raw works. However, the adjustment brush is a critical tool. I have checked my permissions, and even repaired my permissions with no results. Of course I have also tried several restarts to no avail.

Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp50501-51000/sp50856.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook again.

When I use the Iris enhance i'm no longer able to use clarity,saturation,tone,tint etc... why?
Why not? The Iris Enhance Preset sets the brush to Exposure +0.35, Clarity +10 and Saturation +40. If you want additional adjustments on the same brush or different values for the three preset parameters, just move the sliders. -
I use my iPhone in the car. It has been a really useful feature to be able to fast forward and reverse buttons on the steering wheel when listening to an iBook. This no longer works with iO7 and I am really disappointed that I now have to revert to using the keys on the iPhone rather than the cars steering wheel. I also now get regular warnings that the cables I am using were not made for the iPhone. I bought them from Apple direct so what

No longer able to use the scan function on Photosmart c4780
Previously when I opened my HP Photosmart C4780 Printer Scanner I would get a dialogue box which allowed me to choose whether to print or scan. This dialogue box no longer starts and I no longer get the option to select scan and can only choose to print. I have been around the circuit of Print and Scan and Doctor and have downloaded and reinstalled the appropriate software several times all to no avail. I can no longer find the software CD that came with the device. What do I have to do to be able to access the dialogue box which gave the opportunity to choose scan and specify the actions required?
Furthermore using Windows Fax and Scan will not work either, I simply get the message “Could not complete scan”.
The scanner does work as I can use the copy function perfectly well.Hi @Jumbob
From your descriptions, it sounds to me like the issue stems from the software. Let's perform a comprehensive uninstall, clean things up and ensure updates are complete, then reinstall. Please complete the following steps and let me know the outcome;
Hold down the Windows Logo key () on the keyboard and the 'R' to open the run box, type %temp%
Delete all files and folders from the temp folder. Choose skip if any pop ups appear saying any of the files could not be deleted
Download the software and choose to save as, save to desktop > HP Photosmart C4700 All-in-One Printer series Full Feature Software and Driver
After the software downloads and extracts, open the temp folder again, use the instructions from step 1.
Look for, and open the folder starting with 7z (Example: 7zS2356)
Open folder Util
Open folder CCC
If you have an HP computer run the L3uninstall.exe. If you have anon-HP computer run the L4uninstall.exe
When the uninstall has completed restart the computer
Follow these steps to reset the registry settings and options for Windows Installer.
Hold down the Windows Logo key on the keyboard and the 'R' to open the run box
In the Open box, type msiexec /unregister, and then click OK.
Hold down the Windows Logo key on the keyboard and the 'R' to open the run box

We are in the middle of OAKS TESTING. We had to run the latest Java Updates inorder to do the ELPA portion of our State "OAKS" testing. Since last Friday we cannot consistantly or basically cannot get the audio portion to work. The sound and speech works fine in system preference but no longer for the testing. It was fine last week.
Is there other school district having this issue in the state of Oregon?When I try to do a "save as" in preview, pages, numbers, etc., there no longer is a save as in the pull down menu. If a go to help and type save as it will pop up under help - what a pain.
Save as is available in Mountain Lion by hitting the Option key while you access the File menu. (It was returned after being eliminated in Lion).
My system is running slow!
How much RAM do you have installed? Mountain Lion is somewhat of a memory hog. And, how much free/empty hard drive space do you have?
And what is Mavericks? Is that going to change everything?
Apple announced a new OS a few days ago; it is supposed to be released in the fall.
When i open softwares, like quickbooks, it tells me that my QB wants to import my contacts.
The capability to sync is a new feature. You don't need to do it. I did not allow any app to import my contacts. You can also turn off other features if you do not like them - simply go through all the System Preference Panes and decide what you want and what you don't want. -
If I buy an iPhone in China will I be able to use the UK app store with my UK iTunes account?
I am working/living in China, and I want to buy a new iPhone. A friend of mine bought a Windows 8 phone and he discovered that the phones, apparantly all of them (across all brands) are region locked, app store wise, to China. So he can't download apps like Skype for example. I want a new phone but I'm worried that if I buy an iPhone here in China I won't be able to access my countries store. I have an old iPhone but it was from the UK so I know I can access the UK store in China. But the issue is, is that will the Chinese sold iPhone only access their own store and no others like the Chinese sold Windows 8 phones?
Hello Rick19992000,
Welcome to the Apple Support Communities. Look at your question I can say that yes you can change stores. The following article will walk you through it. I also highlighted the specific portion for you.
iOS: Changing the signed-in iTunes Store Apple ID account
http://support.apple.com/kb/ht1311
Sign in to the account for the iTunes Store region you'd like to use. Tap Settings > iTunes & App Stores > Apple ID: > View Apple ID > Country/Region.
One last bit of advice is to check to make sure that certain features are going to be present when buying from a different region. You can compare by going to the different regions at the Apple Choose your Region Page

Hi, Although I had itunes downloaded on my pc & been using for a while now, today I've been prompted to download itunes again. This has been successfull except that 65 songs that I had previously in my library are now no longer able to play, the message informes me that the original files could not be found. Yet these songs are still on my ipod after being syncronised and I can play them on my ipod. Please advise how I can find the original files on my pc.
Thank you
CarolI would copy over the entire thing if you have room. With iTunes 10.4 though, you can download any previous iTunes purchases you have made in the past with your current iTunes account. While in iTunes, look at the left hand side of your screen and select "Purchases" and look at the bottom right corner of the screen and select "Download Previous Purchases". If you have an iPhone, iPod and/or iPad...you can do the same thing from each device. Nice new feature...just remember that those ripped CDs need a back-up!!! Enjoy...

I installed the new version of iTunes today. It's 12.1.1. After completing the installation, including restarting my computer, I was no longer able to use Windows Internet Explorer. Has anybody else experienced this? If so, how did you fix Explorer? I was using Explorer 11 and Windows 7, installed on an HP Pavilion g series
Never heard of that being caused by installing iTunes. Try asking on a Windows forum. This isn't a problem with iTunes or any other Apple product. If you believe it is, uninstall iTunes. If the problem persists, you'll have to seek advice on a Windows forum or contact Microsoft for support.

I am not able to use the ftp export in Muse. When I enter my host, name and password, I get a long interlude of rainbow wheel and finally the message that my ftp host cannot be found. I have verified the name and that it is port 21. I can export to html and use another ftp client to upload (to the same server) but this is tedious and making minor changes is painful. Have you encountered this and found a solution?
Hi Susan,
In that case I will recommend that you consult a local technician/IT team and see if there is some network connectivity issue with your machine.
