Hot or Cold Hook-Ups of the DVI

Many folks talk about their "hot" MB's, and problems associated with their DVI hook-ups. Nobody from Apple has stated just how the plug-in of the DVI to the MB should be done. I the "Old Days", before USB's and Firewire's, you'd never plug-in anything when the computer was on. So Apple, tell us what you recommend--a "hot" or a "shutdown" for the DVI plug-in?

Thanks, Morttt,,,
I certainly know Apple reps don't opine on this site--or even spy on it--, but many surrogates do. I've been with Apple since 2000, have all their products and love them. But, getting answers is like asking a question of Ms. Clinton or any other politician or lawyer. There ain't no answers most of the time.
All I want to know from the inside intelligentsia, is there a right way or a wrong way to plug-in the DVI!

Hook ups

I recently purchased a Apple TV. However, I have an older model Sony Grand Vega LCD Projection TV that has HD capabilities however, does not have an HDMI port, rather it has a DVI-HDTV IN VIDEO port. It shows it needs a DVI-D single link cable. What do I exactly need and how do I hook up the system to sync with the computer.

Short answer is no - Verizon does not support the A/V inputs on their STBs.
You could go to Radio Shack (or someplace similar) and get an RF modulator that automatically switches to your A/V device when it is powered on.

Problem using the DVI to Video adapter

I am using a MacBook Pro. I am using the DVI to Video cable to connect my MBP to the TV. It was working fine and I was watching movies and videos. Suddenly I am having problem and its not working.
I hooked up the DVI to Video adaptor on the PC side . Black and white signal which is blurred/blocked/and modes across the screen. I tried playing with refresh settings, resolutions, etc but nothing is happening
Even in the display I am not able to see the NTSC
settings anymore. When it was working before the display changes automatically once i connect the adapter. But now it refresh but the display is not changing. currenly my display is set to 1440 * 900.
any idea why the display is not working, is it a driver issue.

Have you played with the "Mirror Displays" option in the arrangement tab?

Any noticable signal loss with the DVI-to-video adapter?

Hi, there. Would any of you happen to know whether there's an appreciable signal loss when converting from DVI to, say, composite video via the DVI-to-video adapter? I'd like to hook my MBP up to an HDTV (when I eventually get one), and I'm wondering if going through the adapter would produce a degraded picture for DVDs, compared to a direct digital connection from a DVD player to the TV.
Actually, I'm wondering the same thing about the audio connection. Any loss in audio quality when using an adapter to connect the MBP's mini-jack to an HDTV or receiver?
Thanks much.

ragamoffyn,
While there's no "signal loss," as such, there is a considerable loss in signal quality. However, you're over-thinking this...
HDTVs accept HDMI connections, and your Macbook Pro has a DVI output. The ports are dissimilar, but digital video signal is the same. In other words, you would simply use a DVI-to-HDMI cable. In fact, many HD cable boxes (mine included) still have a DVI port, not an HDMI port. There is no loss of signal or quality.
Really, the only difference between DVI and HDMI is the fact that HDMI transmits both video and digital audio. DVI doesn't do this, so you must resort to transmitting audio separately. Not a problem: use an optical digital cable, which your Macbook Pro will accept (as will most HDTVs). That said, you might be better off connecting the audio portion of your MBP's output to a home entertainment (surround sound??) receiver.
Now, I'm not sure about the "progressive scan" capabilities of the Macbook Pro and DVD Player. You'll have to research that yourself. I can tell you that normal DVDs can be "upconverted" by a progressive scan set-top DVD player, and the result looks absolutely stunning on an HDTV. It's not quite as good as full HD, but it comes pretty close. Also, many newer units are being made with HDMI ports. In other words, the DVD is upconverted, and the result is transmitted over a full HD connection. Best of all, these set-top boxes can be had for under $100.
BTW, the composite video you suggest is simply "standard definition," and not the best SD at that (S-Video is better). Component video (where there are three separate "RCA"-type connectors) is much, much better, but even that doesn't match digital (DVI or HDMI). Also, the DVI-to-HDMI cable you will need can be had at Walmart for around $30. They can also be found at places like Best Buy or CompUSA, but these retailers tend to over-charge for over-blown items (No one needs a "Monster" HDMI cable that costs over $100, and which does no more than the $30 cable from Walmart; digital is digital).

Outputting DVI to HDMI input in LCD TV versus using the DVI to RGB ?

I am thinking of buying a mac mini to connect to a Toshiba 20HL85 TV in the lounge primarily to act as a "media server" and accessing Front Row for music, photo's, DVD watching etc. The question is which connection to use to go from the mini to the TV for Video (audio is fine as it will route into my AV Receiver)? The TV has an HDMI input, component video, s-video and a VGA port. The user manual for the TV says:
Note: The HDMI jack is not intended for connection to and should not be used with a personal computer. For PC connection, use VGA cable and connect to the VGA port. The VGA port allows the following resolutions:
Monitor Display modes:
VGA 640x480 60Hz
SVGA 800x600 56.3Hz
SVGA 800x600 60.3Hz
XGA 1024x768 60Hz
WXGA 1280x720 60Hz
WXGA 1280x768 60Hz
I wanted to know a few things as I have no experience with the MAC mini and HDMI:
1. Will I not get a better/crisper/sharper picture if I connect through a digital port like HDMI versus going through the VGA port?
2. I have checked a few LCD TV's user manuals and they all seem to say the same thing i.e. "Do not connect a PC to the HDMI port" - I fail to understand this when the Apple site specifically says under "accessories for the MAC mini" that "HDMI is electrically similar to DVI, but has a different physical connector that may include an audio signal. You’ll need a DVI to HDMI adapter, such as the Belkin PureAV HDMI to DVI cable to use these televisions".
3. What am I missing? Should I just go ahead and buy the DVI to HDMI cable and MAC mini and plug it in i.e. has anyone done this and had it work? Is it better than VGA (I would hope so)?
Bottom line is does the MAC mini connect to any TV with an HDMI port or are there different types of HDMI ports and hence I need to search for the right TV first? If so, what must I look for? Thanks for any help I can get.
Power Mac G5 Dual 2GHz Mac OS X (10.4.5)

One word of advice. I just hooked up my mini to my 32" Lowe HD TV using a DVI to HDMI cable and it doesn't just work. The native resolution of the TV is not available for whatever reason so I have to bodge another resolution which looks terrible. When I plug my powerbook in via a DVI to VGA connector it just does work selecting the correct resolution automatically.
Either the problem lies with the mini or with connecting to the HDMI socket. As the HDMI is simply a dvi with audio I can't see why it would cause problems but who knows. Given all the other problems I am currently having with the mini I am pointing the finger in that direction currently.

I am trying to hook my macbook pro to a projector, which has a VGA cable. I bought a VGA to HDMI adapter, but whenever I hook it up, the screen on my macbook just goes black and I can't make it do anything else or even show up on the projector.

My laptop is still on; it just has a black screen that I can't get rid of without shutting down the computer by holding the power button.

Hey there lynmrigg,
It sounds like have an HDMI to VGA adapter connecting your MacBook Pro and your projector but the screen on your computer goes black and no image appears on the projector. I would use the troubleshooting in the following article to help resolve or isolate the issue here, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Take care,
Sterling

Turning the DVI out on a PB to be On all the time

This is what I'm trying to do. I'm setting up a 17" PowerBook with two EDTV plasma TVs using DVI cable. Since I'm doing this across a room, it makes it a little more difficult. Here's the set up...the PowerBook is hooked into a 50' DVI cable to a DVI repeater to boost the signal which is then connected to DVI splitter to send the signal to the two different screens. What I'm having trouble doing is getting the PowerBook to recognize that it is plugged into a DVI cable and it won't send a signal. I've tried restarting the computer and detecting displays while the cable is connected and I can't get it to work. We know it's not the cable because if you hook the cable straight into the back of one of the TVs it works fine, but when we try and send it through a splitter it won't send a signal. Is there a way to force the PowerBook to send a signal all the time? Or something at start up that can be done to have it send a signal? Thanks for any responses.
PowerBook 12" 1.5 Ghz 1.25 gigs Ram, PowerMac Dual 1.8 Ghz 1.5 gigs Ram Mac OS X (10.4.4)

I suspect that the Splitter and/or "booster" is the cause.
Does it work when you connect one of the displays to the PB via the cable alone, no other splitters, etc?

Concerning: VGA monitors using an Aluminum Powerbook G4 PowerPC 2004 15"-screen 1.5Ghz
The DVI (converted to VGA) video output stopped working on this computer after 9 years of service. This raises question 1:
Is there any way of fixing this? I've tried the usual: triple checked all vga cables & devices through trial & error. Bought a new DVI-VGA adapter. Reset PRAM, PMU, etc. Nothing works. Something is probably damaged, because my KVM switch was not working unless I hot-reseated the vga cable into it, leading to this DVI port, and that is pretty rough stuff.
Question 2 (related):
This dovetails into this: Can I drive a VGA monitor with the s-video output port on this computer. It would take an s-video (male)-to-15-pin-VGA adapter. Has anyone does this? So far, I haven't even found the adapter mentioned anywhere.
Thanks for reading this.

Thanks for the useful feedback, Knucklesmac. I agree. I must have blown something on the logic board -- because I had a faulty old KVM switch that would not switch between computers without some nasty hot-plugging/unplugging the VGA video cables. (wince!). It's like when Dizzy Dean ruined his arm because a line drive hit him in the foot and he readjusted his mechanics around the injury. I take the blame because this has been a great computer, and does not deserve any blame.
If it will help anyone else reading this thread, C2G (née Cables to Go) has some interesting ideas for still getting external video out of this computer:
-USB-to-VGA
http://www.cablestogo.com/product/30545
-Convert s-video or composite video signals to high resolution VGA
http://www.cablestogo.com/product/40971
The price range is $75-$85, which doesn't make horse sense to me for such an old computer -- which has a lot of life in it anyway, because its own 15" monitor is not chopped liver.

What do I need to hook up an external DVI monitor to Thunderbolt?

I want to hook up an external DVI monitor to my new iMac.
It has a thunderbolt connection.
http://www.amazon.com/Apple-Mini-DisplayPort-Adapter-MB570Z/dp/B001IF5YLQ/ref=sr _1_1?ie=UTF8&qid=1309558497&sr=8-1
Is the above link what I would be looking for? I notice this is for "Mini DisplayPort" and not Thunderbolt?
Just a little confused Thanks.

You are quite correct. That's the device you need. Take a look at your plug and the plug in Amazon's picture for a final check. If that looks good, click "buy"!
ThunderBolt supports "mini display port".
Since adapters have been around for a while, they typically don't say anything about ThunderBolt - it's too new. They talk about "mini display port" only.

Highlight Hot and Cold toggle turns entire Image RED!

Hi,
I'm curious if anyone has a solution to this issue. I'm using Aperture 2.1.3 on a Macbook Pro running OS Version 10.5.7. I shoot Nikon RAW files and a while back when I hit the ever helpful Option-shift-H (to toggle the Highlight Hot and Cold feature), I end up with the entire image turning red (Hot). Now the histogram is fine, I just can't fine tune the hot and cold areas with the feature. . . I've tried reloading Aperture 2 from the original disk (I did not delete the original copy firs in fear of loosing my images).
This feature worked fine until about 6 months ago- it probably stopped working during one of the updates. . . The "creative" at the apple store scratched his head and suggested I post here for a solution. . . Any help world be appreciated.

In Aperture try this:
Go to Preferences (cmd+,) -> Appearance
Then set
Hot Area Display Threshold to 100%
Cold Area Display Threshold to 0%
You might have set hot to 0% which would cause all parts of the image to appear red.
Just play a bit with those sliders to get what you want.

Toggle on "Highlight Hot and Cold Areas"

Aloha all.
When ever I toggle on "Highlight Hot and Cold Areas" my image turns solid red. I know I must have a setting turned on or set too high but I can't figure it out? Anyone else with this problem? Solutions?
Using Aperture 2.1

In Preferences->Appearance, see what the hot area display threshold is set to. It should be 97 or higher.

Hot cloning & cold cloning

i need hot cloning & cold cloning documents

This is something strange to me. What do you mean by "hot cloning & cold cloning".Database cloning is part of Application cloning. When you clone Oracle Application, you need to run pre-clone and post-clone on both the application and database tiers. To clone the database, either you shut it down and copy the files (cold backup), or you can use RMAN to recreate the database (hot backup).
What I know is, using Hot/Cold Database backup can be performed cloning of a database. How this cloning & cold cloning relates to Oracle ApplicationsAlready answered above.
Only the possible method for Cloning Oracle Applications Release 11i/12i is with Rapid Clone.For non-AutoConfig enabled systems, you cannot use Rapid Clone. Instead, you need to follow the steps in "Cloning Oracle Applications Release 11i" paper/note.

Hot and cold backups

i am learning to take hot and cold backups and i am having doubts regarding restoring and recovering/
1. When restoring the cold backup .. i am copying the control and datafiles from the backup and then starting the database with reset logs is this enough?
2. When i am recovering a tablespace in hot backup .. i have replaced the file from backup. I need to do something with the archive log files. Where do i place them in the database? If i have done some transactions after taking the hotback.. will i loose those transactions?

"1. When restoring the cold backup .. i am copying the control and datafiles from the backup and then starting the database with reset logs is this enough?"
Yes, you are right.... also include password file in your backup file list...
2. When i am recovering a tablespace in hot backup .. i have replaced the file from backup. I need to do something with the archive log files. Where do i place them in the database? If i have done some transactions after taking the hotback.. will i loose those transactions?
You can place the old datafile at new location also. For hot backup, your DB must
be running in archive log mode, so you will not loose any transaction.....

Highlight hot and cold areas

When "Highlight hot and cold areas" is turned on I often get some blue outlines in a photo, but when I press "Z" (zoom) they disappear. What is going on?

Could be a number of reasons for this but nothing to worry about. You could try looking at the hot/cold threshold levels but you need to remember smaller images can't hold the same amount of data as large ones. Edge sharpening for example, on the large scale may contrast 10,000 pixels along a 1 inch line to the full size image. Now think what has to happen when the image is shown as a 7x5. Think of it in terms of Bit Depth. With 1 bit there is no grey area and choices have to be made about what to show. In this case it is not a perfect copy of the full size image. Allan

Hot and Cold area viewing confusing me...

Hi Everyone,
I've been using Aperture 2 since it came and I'm liking the workflow and integration with the rest of OSX. Today I stumbled upon something confusing. I was playing with the display hot and cold areas option and was finding that when I measured the hot areas with the loupe, that the color values weren't actually blown out...
For example, I had a picture of a rose that when zoomed in, I could see the detail in the petals but was still being flagged as blown out. When I did a loupe rgb read on a 1x1 pixel point, I found that the red value was around 211...I thought that hot areas are 255?
Maybe I'm confusing what "hot" means. I've even seen cases where the master image is flagged as having more hot areas even though it is less saturated and exposure level is lower.
Can something be wrong with the hot/cold area function? Can anyone give it a try and see what kind of values they are seeing with the hot and cold area viewer?
Thanks.

Hi stjuste
re Maybe I'm confusing what "hot" means. I've even seen cases where the master image is flagged as having more hot areas even though it is less saturated and exposure level is lower.
Thought I would check. Used a pic of a dancer at night with firebrands. Pic looks good as I shot it.
Measured the "Hot Spot' at 255, and some others at a lower value. The manual says:
Images may occasionally have overly bright areas where color information about the
area is beyond the standard limits of the Aperture working color space. For example,
white areas in an image brightly lit with direct sunlight, or bright flashes off a water
surface, may be so bright that their color is outside the working color space. In addition,
images may occasionally have black areas where color information about the area is
below the standard limits of the working color space. Aperture can display these “hot”
and “cold” areas of an image with tints on the image to help you identify hot and cold
areas. You may be able to adjust these areas and recover highlight and shadow detail
identified by the hot and cold area overlays by changing the exposure, the recovery, the
black point, or the gamma setting of the image.
This maybe of help.. maybe not. Probably like you I set up the pics how I want them not what any program tells me.
Interesting though. I will do a bit more checking.
Cheers
Tomix.
