Resolution Problem Connecting MBP to Envision Television

Hello, I am using a MacBook Pro 15" 2.16 Intel Core Duo with 2 gigs of RAM and an ATI Radeon X1600 256 MB RAM graphics card and I am connecting it to an Envision 19" L19W698 Television via a HDMI to DVI cable and I am not getting the supported 1440x900 resolution. Heres the thing, I first connected the display via a VGA to VGA/DVI converter to the MBP and it supported a 1440x900 resolution and the picture quality was great, so I thought I would simplify things a little and got a HDMI to DVI cable since the TV supported HDMI. I set it up and the supported resolutions are:
640x480
720x480
800x600
1024x768
1280x720
1440x240
1920x540
With the automatic resolution set to 1024x768 at 60 hertz. I change the refresh rate and nothing happens, I tried putting the display pref in the menubar because I read that sometimes helps, I restart, reconnect, log out, etc... and the resolutions do not change. My question, is this an issue with the second display, with the cable or with the MBP and is there anything I can do about it? Thank you.

Welcome to Apple Discussions, dsp2222.
I'm guessing the TV doesn't support a native resolution input over HDMI. That's not as unusual as you might imagine on lower end TVs. Does the Envision user manual say anything about making computer connections? Does it say it works over HDMI?
Often HDMI is dedicated to devices that output standard video formats of which 1440 x 900 is not. That's a long way of saying you are probably stuck with the VGA connection.

Problems connecting MBP to TV

I am connecting my MBP to my LG lcd tv via the mini display to VGA cable. the connection and everything works fine. but when i try to watch a movie or tv show on itunes, it will not play on the tv. even if i start out with the itunes window on my mac screen, start playing the movie, then drag it over to the tv screen, as soon as the itunes window reaches the screen, it will stop playing. i know the cable is good, i run sound and lights at my church and i have it connected to our projector every week with no problems and i can play movies and everything, but for some reason it wont work on my tv, anybody know how to fix this?

Dont know about VGI cable but
I know some people when using HDMI cable forget this
Plug it in first switch on TV, so Macbook will reconise it. In System Preferences,Display etc
then select Arrangement, then tick mirror display. then go back and go into Sound, select Output and tick HDMI cable.? This will get your icons onto your TV and Sound

Problem connecting MBP to established Linksys wireless network

just got MBP 2.16 (my first mac!). Having trouble connecting to my established linksys wireless network. I have the BEFW11S4 (V.2) etherfast wireless access point + cable router with 4 port switch. Currently have 128 encryption enabled. The linksys router is broadcasting its ID (I can see "linksys" on my mac) but it seems to not accept the password. I tried entering the 26 WEP key, the passphrase, the WEP key in quotes, the WEP after a $ sign... all to no avail. please APPLE community, help out a mac noobie before i have to turn back to Bill Gates....

To find the IP address or the status, go to system Preferences then network. It will show you the status of any internet connections. You should see one for Airport, it will either show a green light and say 'Airport is connected to the internet' (or something like that) or a red light and say 'Airport is is active but not connected' (something like that). If you double click on Airport or click 'Configure' you will see tabs, click on TCP/IP and it will show all of your details including your IP address.
As for the other, it always refers to wireless networks as 'Airport' and that response is the standard response from a Mac.
the password should be typed in the hex section, not sure about the $ sign. I've never had to do that before. But if you can't connect even with no encription then I would think it is another problem. I would turn off the encription until you can at least get connected and then you can worry about the security afterwards.

Problem connecting MBP 17" to 37" LCD Philips

Hi all,
I recently bought a new Philips flat TV LCD model, the top-range for their 37 inches production (3ms panel, one of the fastest).
This tv has 3 HDMI connections , and should support PC connections (it's a full hd , with support for 1080p connections).
2 days ago I bought an HDMI-DVI male cable, and tried connecting my MBP 17" (2.16GHz) to the tv.
I wasn't able to let my Mac detect the lcd tv. I tried switching all the resolutions, then pressing Detect Display button, or switching channel back and forth on my tv to let the HDMI connection be engaged.
What I obtained was only a temporary blue screen on my Mac when I switched channel on the TV.
The TV manual explicitly says that it supports DVI connections from a PC. They must be at 60Hz refresh rate.
Anyone who can help me with any suggestion?
Thanks in advance

If I were you I would check the TV's plug-and-display driver for clues. This requires downloading and installing SwitchRes X (I recommend the Control Panel version over the full version because the full version requires a helper application to be installed). Once SRX is installed, with the TV hooked up to it, click on the "Export DDC" button. This will create a text file from the driver data inside the TV. Post it here and I'll help you interpret it.

Problem connecting MBP to established Linksys wireless network (Part 2)

Thanks to all who followed part 1 thread. I have been trying to wirelessly connect my new MBP 2.16 to my established linksys BEFWS11S4 network. I gave up on 128 encryption for now, MBP couldn't take it.
by playing with the setting and manual config I can get the MBP to connect to the linksys network, (I even see the mac on my Win XP's DHCP master table). In the network utilities I get a green status light. when i run diagnostics i get a green airport, airport settings, network settings and ISP. STill red are "internet" and "server". no conncetion with safari...
I know the MBP works becuase i was able to connect to my neigbors wireless network and will work when I hard wire it through built-in ethernet.
Anyone know why the airport wouldn't work here? any thoughts appreciated I have spent way to many hours on this......

OK so your router is issuing IP addresses. However, I would say there is definately something wrong with your router's config. Maybe your DHCP server on your router is switched off? Anyway by adding your own IP address that is half the battle, as you need more than an IP address to connect to the internet, that's why you can see it in the list but cannot connect to the net. When a computer is set to DHCP it sends out a message to any DHCP servers requesting an IP address, if it gets no response in a set time, it issues itself an address, like yours is doing, the address will probably look like this: 169.254.14.192, it's called an APIPA address (Automatic Private IP Addressing)
You see a router uses a NAT (network address translation) so that from the internet all the machines connected to your router would show the same IP address which would be the one supplied by your ISP. For this to work, each machine on your network needs to have a default gateway, which is the IP address that your outbound traffic goes to. If your router is not issuing an IP address then it's probable that it's not issuing this data also, so you can add it yourself.
On your windows machine, go to a command prompt Start>Run type cmd and press enter, then type ipconfig /all press enter, it will show you the IP address of your PC, your subnet mask and your default gateway. I am going to assume that your IP address is in the 192 range as most Linksys are. So let's say your IP address of your router is 192.168.1.1 (on the new ones they tend to go with 192.168.1.15) so whichever yours is, that is your default gateway, as that's the address of your router. So your PC may have 192.168.1.100 as it's IP address.
On your Mac go to the System preferences>Network and the TCP/IP tab and select manual setup in Airport. Type in an IP address like 192.168.1.101 (or one up from your PCs IP address, then type in the subnet mask 255.255.255.0 if that is the same as your PC and then where it says Router (this is the default gateway address on a Mac), type in the default gateway here. Select apply and that should now connect to the internet.
I would only use this until you can resolve your Router's issue. Maybe you can call them back and tell them your router is not issing IP addresses. Or get a friend to try his laptop and see if he gets one. If not then you know it's your router. I would bet money that it's your router, that's why you can connect to your neighbours but not yours. Also remember if you keep the manual setup if you go travelling, remember to change it back to DHCP or you wont be able to pick up any hotspots. You can save a TCP/IP setup on a Mac so you could save the setup and name it and when you go travelling change to default, or auto.
Let me know how you get on.

Problem connecting MBP to HDTV

I ordered a DVI to HDMI cable and hooked it up to the my Toshiba HDTV and I get a picture, unfortunately it's not what I'm looking at on the MBP. Strangely it is the blue design that is the desktop background when you pull the MBP out of the box and it does not change if I open up programs, etc.
What do I need to do to get my MBP screen to show up on the TV?
Thanks!

you may have your screen in extended desktop mode, so the HDTV is just a second display that allows you more desktop space, that's why it's not showing a duplicate of what you see on its display. if you move the mouse pointer, you should see it goes over on to the HDTV and you can drag windows there etc.
if you want to change it to desktop mirroring, you should be able to do so in the displays pane in preferences. that way, both displays will show the same thing.

Display problems when connecting MBP to LG 30FS4D HDTV

Apologies if a similar post has been asked before. Most questions related to this are with LCD TVs.
Problem description :
1. I connected my MBP to my LG 30FS4D HDTV ( this is not an LCD ). Both handshake and I can see the output on my TV. MBP display the tv control panel. But the output is just like s-video...probably not as good as that either !
How I connected it to the TV :
2. miniDVI to DVI adapter ( $19 )
3. HDMI ( $10 )
What I have tried so far :
4. I changed the resolutions on the MBP tv display from 720p to 1080i, also other resolutions....but none of them is good quality !
Questions :
5. What kind of output should I expect on my tv - I was expecting at least a DVD quality output...but it's no where close to that ?
6. Do I need to get expensive HDMI cable for this ?
7. Is my TV the culprit ?
8. Should I try this on someone's LCD TV ?

For anyone who's facing a similar issue :
Some of these slim TVs switch off other audio input when you connect the HDMI cable ( HDMI is after all, audio and video ). But there is another audio input - the digital optical audio input. In order to get the sound, get a toslink cable ( with optical audio male at one end and a simple headphone male at the other end ) and connect it from your MBP to the TV optical audio input.

HD receiver/amp connected to non-HD TV - resolution problems?

My 10 year old receiver/amp (non-HD of course) went belly up! My current TV is not HD & I'm not ready to spend the money for an HDTV monitor at this time.
If I buy a HD receiver/amp will I have resolution problems with the current TV?

No, receiver/amp simply passes video signal from your source to the TV.

Problem connecting MacBook to a Sharp video projector

One of the great things I like about Macs is the easy way they (usually) connect to a video projector. Unlike a lot of my friends who run PCs with Windows I never had any problems whatsoever connecting my MacBook to a projector at the university and start my presentations.
Until today that is.
I tried to connect my MacBook with Apple's mini-DVI to VGA adapter to a Sharp ("Notevision") video projector and although the MacBook had the projector (even with its correct name "PG-M20X" and available resolution settings) listed under "Displays" immediately, I couldn't get the projector to show any more than "no signal" whatever input source I chose...
What did I do wrong? Or is it the projector that is somehow "incompatible"?! Please help!

MacBook Mac OS X (10.4.9) Core Duo 2GHz, July 2006

Maybe this could help as well:
After we tried several things with the MacBook (reboot, "detect displays" etc.), we successfully connected a Powerbook (15", FireWire 800, late 2003) to the projector, using Apple's DVI-VGA Adapter.
So that did work out fine, but the MacBook didn't work on the projector. The cable that came with the projector was a VGA--DVI-A cable: there were only a few pins on the DVI-end of it going into the DVI-Connector on the projector. Could it have something to do with that? But why didn't the Powerbook have any problems connecting to the projector then?

What is the ideal resolution combo for MBP 13" and Projector?

In our school district we are using 13" MacBook Pro's (OS X 10.7 Lion) and external epson projectors, projecting to a Promethean Smart Board. The default resolution for a MBP is 1280X800, that is a no brainer. Now everything I've been reading says that projectors like to be on 1024X768. When we do that the projector resolution dictates that resolution to the MBP screen and the MBP screen is of course distorted. They don't play nice when trying to set independent settings. We've found that 1280X800 for MBP and 1280X960 for the projector works best. When set at these settings and you plug and unplug the VGA adapter the settings on the MBP hold to 1280X800. But we have to keep calibrating the Promethean Smart Board though inbetween plugging and unplugging the VGA adapter's. Any ideas?

Try setting up the projector at 1024x768 as it calls for, but you want to use the best image. This might require a resolution reset as you are dealing with 3 different viewing sources. (ahh, if only they would come up with a standard.
You can try a pram reset with everything up and running, this can sometimes correct distortions.
NVPRAM reset:
Power down the mac, power it back up, before the start up chime, press and hold the following keys:
option,command,P,R,(no commas) and continue to hold these keys till you hear the start chime 2 times. See what you have. You might have to reboot.
Also you can try connecting the projector, fire up the mac then the projector, it might auto-detect. You can try system preferences click detect displays,
As for the smart board, you would have to contact the manufacturer for details.
I know I have not offered much here, but it's worth a try, can't hurt anything.
Also, if you plan to contact the Community in the future, please ammend your profile with the model and OS you are using, as it could help you get more info.

In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

Problem connecting to the server Timecapsule

I am working with a Motora Surfboard SBG6580 Cable Modem going to my 4th Gen Airport Extreme, then a wireless bridge to my 3rd Gen 2 Gig TimeCapsule to extend the network, then using ethernet cables to TV, DVD and MacMini. When trying to run a backup with Time Machine, or just using it as a hardrive, I keep getting the error message "There was a problem connecting to the server "Timecapsule" - The server may not exist or is unavalable at this time. Check the server name or IP address, check your network connection, and then try again." I have seen a lot of posts on this problem, but I still don't understand what the issue or resolution is.
I have tried resetting the TimeCapsule, connecting the TimeCapuse with an ethernet cable, turning off wireless functions, wiped the drive and zero'd all data, etc., but with the same results. I may be wrong, but this all seems to have started when I ran MATCH while using the TimeCapsule as a storage device for all my iTunes media - it corrupted all my data and showed my disk as full, though pretty much everything on the disk was missing. All was working fine until that point.
Any help would be nice. Help!!
Thanks in advance

If you have backed up to 77GB or something then a backup has indeed been made.. On the TC there will be a sparse bundle and backup which can be mounted.. You cannot check the disk.. you check the sparse bundle.. which can be mounted.
Please do the following.
Disconnect and remove the TC from the network.
Plug it directly into the computer by ethernet. No other connection to the TC.. turn off wireless and every other connection to the computer..
If you still have issues.. press reset and redo the setup of the TC again.
Run Time Machine and see if it works. If it doesn't work now you have serious issues.. I would guess at a faulty disk somewhere.
What OS is on the computer? From the first post you use SL still.
I would also take the firmware of the TC back to 7.5.2 as I mentioned and do full factory reset this time.. ie hold in reset and then power on.. continue holding in reset until led flashes rapidly.

Xp networking problems on mbp c2d

i don't know if this problem should be addressed under the mbp forum or boot camp forum so i'll post in both to get the most input.
i'm having a problem connecting to my home wireless network under bootcamp. i installed xp sp2 as well as the driver cd. when i try to connect to my router it takes a long time detecting the network type. then it pops up a window that says "windows is unable to connect to the selected network. the network may no longer be in range. please refresh the list of available networks, and try again." when i connect to another network in range (that has 0 bars) it quickly detects the network type and gives a window where i can enter the wpa password (which i don't have).
the mbp connects fine under os x. my mac mini along w/ a few windows computers in the house have no problems either.
our router is a 2wire that has wep encryption. the ssid is broadcast and found by windows.
any help would be great. this is driving me nuts!!!

That behavior is normal. Intel's chips use a technology called (I believe) "SpeedStep", which dynamically adjusts the processor speed as is needed. This improves battery life and has no impact on performance.
With respect to quitting the battery, I assume you mean to remove it... This will, in fact, freeze the processors at a max of 1GHz, which is a safety feature.
A quick review of these forums would have revealed that, btw.
Thanks for trolling, though!

How to fix resolution problem in Photoshop CC for Macbook Pro w/ Retina Display

I design email promotions for my website in Photoshop CC on a new Macbook w/ retina screen. However, document sizes appear much smaller in my Macbook than they did on my windows laptop. A 700px wide document now appears to be 350px wide.
When I designed the email graphics, upload, and then view in a browser, everything is pixelated. The document/graphic is still 700px, but its pixelated in the browser. After some Googling, I have a better understanding of the problem but not a complete understanding. Its all so technical. I've read that some designers choose to create their graphics with another lower resolution monitor connected to their Macbook (if I explained that correctly)... not an option for me, though, unfortunately.
How can I fix this problem? I basically design for the web so its important that these graphics are at their highest resolution when viewed on a web browser. Any solutions? Help! I will try everything in my power.

First of all, thank you so much for taking the time to try to help out. It
is much appreciated.
The two things that first come to mind are: I have many friends in the
industry who paint solely in Photoshop and do just fine. My computer is
technically "old," but the specs are still just fine—even the graphics card
is the exact same one that is in the new Cintiq Companions (the all-in-one
computer/cintiq machines).
And, more so, I was painting on it for a few weeks without noticing
anything. A part of me wonders, did I just not notice it until it became
dramatically worse?
I do remember painting fur, which requires making tons of small brush
strokes over an extended period of time, and I don't remember there being
any lag.
By the way, I forgot to mention: I've even tried going into the Performance
preferences and disabling the graphics card altogether. No luck. Still an
issue.
As far as painting at 100%: I do notice an amount of improvement. The one
brush stamp, or space, whatever you call it, issue only happened on the
first brush stroke (every time) and then just once otherwise. The lag was
tremendous—and I compared it to Painter's performance, which had no issues
whatsoever.
I am really hoping to be able to rely on Photoshop more and more, as its
tools for other aspects of image manipulation are far more robust than
Painter's. And the working compatibility with Adobe InDesign, Flash, and
Adobe Media Encoder are sooooooo useful for speeding up the workflow.
Hopefully we can find out what's going wrong.
I'm truly baffled on this one.
