IMac to "PC in" on a Toshiba HDTV

Hi all,
I want to hook my iMac up to the "PC in" (VGA port) of my Toshiba HDTV, and I did with adapters and cabling, but the picture is a bit distorted and it's very green. Anyone experienced in getting this to work.
I have puck type X-Rite Display Color Calibrator. Could I use this to calibrate the TV make a profile for it? Anyone else doing this?
Any and all help would be appreciated.
Thanks, and so long for now, TOM

Hi Allan,
Good points. I can remember way back when on old PowerMac 8500, 9600, having a special adapter which was used to hook up monitors and prevent the green problem. It had setting you could dial in depending on the resolution of the monitor you were connecting. I think it was called Sync on Green or something like that. Maybe it's a hold over issue. Or maybe not?
The computer is set to 1440x900 on the iMac, and the VGA Monitor (Toshiba HDTV) shows up as a VGA device in the Displays System Preference Pane. I am able to control the geometry (but not the color) of the image on the TV using the PC setup and change the way the screen is viewed: actual, stretched, or Dot by Dot.
I was really hoping I could treat the screen as a separate monitor so I could profile it, but there doesn't seem to be any way to do that with Apple's software, Displays Preference, unlike when an actual external monitor is connected. I need to get out the Colorimeter and try it anyway.
iMac G5 Video Out>> Mini VGA>VGA Adapter>>6 ft VGA>VGA Cable>Toshiba PC In VGA on the TV
OS is Leopard X.5.8.
Just discovered a separate issue with the iMac G5. This computer when left on and asleep, has the screen become totally inaccessible and black, and even though I can hear a hard drive (actually feel the vibration of it), I cannot wake up the machine or get it to respond. Oh joy. It's always something. I wonder why? THis did happen a few times since I installed Leopard, but do not think it was happening with X.4.11.
As always, tips, tricks, techniques, comments and poignant and pithy writings are appreciated.
Thanks, and so long for now, TOM

From the menu bar, select
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
Start up in Safe Mode and test.
Reset the NVRAM.
Reset the System Management Controller.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive is malfunctioning.

New Toshiba HDTV with DVD

I recently pruchaed a new Toshiba HDTV with built in DVD. When I hooked it up to my Verizon Cable connection my cable remote will not control ON/OFF or VOLUME. I have to turn the tv on with the Toshiba remote and also use it to control the volume. How can I get my Verizon Cable Remote to control ON/OFF and Volume? Thanks mdc/

You are using an external tuner (cable box) that is why volume adjustment using the cable's remote will not be applicable. Volume is part of the TV's settings. To control the TV's settings (Like the volume) you need to program the cable box remote (If applicable).

Macbook Pro and Toshiba HDTV Hooked up but no streaming

I hooked up the macbook to my Toshiba TV using proper cords purchased at BestBuy (Dvi and HDMI) I set the TV to HDMI and it displays the original wallapaper (the purple space scene - which is no longer my background) and that's it. I can have the netflix video playing on my laptop and nothing appears on the TV.
I don't have the TV manual any longer. I am running Snow Leopard.

The TV is being run as an extension to the desktop, meaning additional space to the normal screen and desktop. You will notice that you can move the cursor onto the TV from the MBP. Also, you can drag windows to the TV's desktop from the MBP's desktop.
If you open Displays Preferences and click on the Arrangement tab, you will see small blue rectangles meant to represent the two displays (MBP's built-in display and externally attached display). Note that one of the blue rectangles has a white bar across the top. This is meant to be a representation of which display has the menu bar (and Dock). You can drag that little white bar from one blue rectangle to the other. This will cause the real menu bar to move from your MBP's screen to the TV. Try that and the function of the two displays will flip flop, meaning you can now see Netflix on the TV.
Note that you can also rearrange the placement of the blue rectangles to be more in keeping with the actual arrangement of the displays. You can also turning mirroring on and off. With mirroring, the MBP's screen and the TV will both show the same thing, but not necessarily at the best resolution.

Toshiba HDTV for a monitor

I just got a K450e desktop. I have used a Toshiba 23" HGTV as a monitor on two other computers. When I connected to the new K450e, the system recognized the TV. However, the TV won't show the icons on either side, so I can't navigate. I changed the resolution, but that didn't help. Any suggestions? TF

You are more than welcome. I'm glad to help.
No problem with the Star Kudo. The forums are currently trying out a new format so the Star button may or may not be there when you visit. Just knowing your problem is solved is enough.

G4 Mac Mini with Toshiba CRT HDTV

Hello all. I'm trying to hook up my Mac Mini (original G4 model) to my Toshiba HDTV (30HF85) using a Dvi to HDMI cable (DVI-D; a basic cable purchased from amazon). Unfortunately, I'm not getting any picture at all - just a black screen. I'm sure that neither the cable nor the hdmi port are faulty; I ran another mac (2005-6 G4 Powerbook) through the cable to the TV, and got a very clear picture. Likewise, the mac mini is still in working order, and connects with no problem to an any VGA monitor via the included DVI-VGA adapter. I have a suspicion that it has to do with the cable I purchased - it's Dual link. I've read in some places that this shouldn't matter, but in others, that this is a problem for older mac minis. Any ideas about what's going on here?

Since you have two Macs, I recommend you try the following:
• Hook up the G4 PowerBook to the TV and open Displays preferences on the PB and make note of the resolution in use that is giving a very clear picture.
• Enable screen sharing on the mini (using a computer monitor if you have to)
• With the mini connected to the TV, share its screen to the PB and from the PB you should be able to set the mini to the exact same setting that is working so well from the PB.
About your dual-link question, I doubt that's the problem. HDMI to dual-link doesn't even make sense because and HDMI connector doesn't have enough pins to hook up to a dual-link DVI connector.

24" iMac and HDTV?

Does anyone know if the new 24" iMac is capable of displaying true HDTV for use as an HDTV and/or HD DVR? From the pixel dimensions of the display itself, it seems like it should be able to, but I was looking for some expert advice.
Thanks!

Eric & Glor,
Thanks for the lightning fast responses. Glad to hear this should be feasible. I'm trying to "convert" a friend who is remodeling their kitchen and wanted to include a 23" LCD TV/monitor (with HD-capability) with a computer for web-browsing, e-mail, photo slideshows, etc. What better way to do that than with an iMac, right?!?!
The HDTV part isn't crucial at the moment... but they want to know that they have the option if they decide to go that route in the future. I didn't want to recommend the iMac and then have it turn out it wasn't feasible.
Thanks again for the help!

IMac to component HDTV?

Situation: I hate Comcast. I have a new LCD HDTV that has a built in HD tuner and now I can pick up all my local HD channels with only basic cable! Score! $14.99/mo! Sweet. NOW HERE IS THE ISSUE: If I do this, I will not be able to pick up HD on my old Mitsubishi 1080i HDTV (set up in my home theater, no HD/digital tuner and has component video input only).
I plan on putting Miglia TVmini HD on my iMac core 2 to pick up the HDTV, very nice and easy! I am thinking, instead of buying a stand-alone HDTV tuner for the Mitsubishi, I would hook my iMac to it as a secondary display. HOW would I make a video connection from the iMac to the Component video of the Mitsu? Second Q, what about the audio for my bose system? Any thoughts?????

Hi kwandrews,
Connecting your iMac to your TV shouldn't be a problem.
You need a mini DVI > DVI adapter (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=6C0 4E07A&nplm=M9321G%2FB), a DVI > Component adapter (like this: http://sewelldirect.com/dvivideoadapter.asp) and a Component video cable (like this: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=149 730D6&nplm=TL953LL%2FA).
I am unshure of what resolutions you will be able to feed your TV with, however. Maybe someone else has a similar setup that can share more info.
Audio isn't a problem either. Your iMac has a analog/digital combined audio output. Depending on wether your Bose system can take a digital toslink or an analog signal, you could use this: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=6C0 4E099&nplm=TA968LL%2FA or any minijack > RCA cable, really. Analog cables won't support surround sound, though.
Hope this helps!

What kind of wireless bridge would work with Toshiba Regza HDTV & Toshiba Blu-ray DVD Player?

What will provide wi-fi to Toshiba DVD player connecting using an ethernet cable, giving an internet connection.

Thank you for this answer. I have another clarifying question for you as I am a wet behind the ears newbie at this. Does this mean that my 2 Wire DSL modem will be acting as the router that you mention? If yes, it would seem that this would also allow me to watch NetFlix movies from my computer on my Toshiba HDTV-correct possibly?

Mac Mini HDTV

Have 2005 Mac Mini with DVI-I connector. Have a 2009 Toshiba HDTV 15" with component, composite and S Video connections. Have found DVI-I to component adapter thru amazon.com. Will the Mac Mini video card support that configuration? What's my best bet? Component adapter or buy Apple's DVI to Composite/S video and add cable?

There is a picture size menu - Theatre Wide 1 seems to be the best setting for the computer, but of course its contrived and stretches the sides, looking unnatural. Also, when you switch between video (the S video from Mac Mini) and television, it doesn't save the settings.
I clicked on the green resize function in Safari and its all screwed up. The images of the web pages are displayed way off to the right. You can drag your way to the images but can do little else. This is my father's set up and trying to add "resize" to bookmarks bar but can't remove any to make room. "open book" doesn't appear on bookmark bar.
Firefox acts fine.
Thanks for your help.

My toshiba external hard drive is not being recognized, except when I eject it. I have the preferences checked to show icon and have checked utilities folder. nothing. Help!

I have a iMac, Yosemite 10.10 and my toshiba external hard drive is not being recognized, except when I eject it!. I have the preferences checked to show icons and have looked in the utilities folder..nothing. I have also changed ports. ??

A few things to try:
1-Repair permissions and restart your computer.
2-Zap the PRAM
3-Use Software Update/App Store to update your OS to OS 10.10.3. Also, update everything SU/AS has to offer for your computer. When done, repair permissions and restart your computer.

IMac to an LCD TV, Ahhhhhhh!!

Hi
Sorry if you've read this but i posted it in the wrong forum earlier.
I have plugged in my iMac to an LCD TV using mini DVI to HDMI. Now is it possible to turn the iMac screen off and just leave the HDTV screen on?
If not this would be a great feature to have in 10.5 as increasing numbers of people have the macs in the longe, and it very annoying having the imac screen on whilst watching movies on the 32" lcd.
many thanks, Ben

I don't believe there is a way. You can always cover the monitor with a towel or something similar. I have a cover made especially for my iMac from acmemade.

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.

32DT1U HDTV: HDMI to Laptop, Sound to External Speakers?

Hello,
I have a 32DT1U Toshiba HDTV and I am trying to connect my laptop to the TV via an HDMI cable but I want the sound to go to external speakers. Is there any way of doing this? When I have the HDMI cable connected from the laptop to the TV and a Y-cable (red/white audio rca) connected from the laptop audio jack to the external speakers the audio still comes from the TV. Any help is appreciated.
Thanks.
Solved!
Go to Solution.

Nevermind I found out how to do it. All I had to do was right click the volume icon in the taskbar, select Playback Devices, then set the headphone or line out to Default.

Regza LCD HDTV 52XF550U has wide black stripes on the right side

Hi, my 2008 REGZA LCD 52XF550U has wide black stripes on the right side. I think the problem started within 24 months from my purchase. And the stripes are getting wider.
I have tried to reset the setup, power off and on, all to no avail. See attached picture.
If someone can shed light on this problem and its (preferably permanent) fix and approx. cost, it will be greatly appreciated. I could simply chug this Toshiba LCD and buy another non-Toshiba HDTV, but I think that would be wasteful if it can be fixed.
Regards,

I also have the same problem. I have had the TV for about 4 years; started right after third year. I have not been able to fix it either....Time to buy a new TV, but defintely not a Toshiba!
