Swap 15" iMac flat screen monitor for 17" one?

My mom has 2 older G4 iMacs, the one with the hemispherical base. One of them has a 15" monitor (that's the one that works); the other iMac has a 17" monitor, but the power supply on that one is dead.
Can we swap out the 15" monitor for the 17" one? Any links for how to do that?
Thanks,
Barbara

Hello and Welcome to Apple Discussions.
I'm fairly sure the part numbers are different for the PSUs on these two iMacs. Could you let us know the processor speed against screen size for each one so we can check that out? ( menu > About this Mac)

Best Flat Screen Monitor for G4 and iMovie?

Since spending so many hours in front of the computer monitor editing my iMovie project, I have developed serious neck, shoulder, and arm pain and my back doesn't feel so great either. I feel this is directly related to the angle of my monitor and the amount of space it takes up on my desk. It crowds the keyboard to the front of the desk, leaving no arm support, and is not adjustable, adding to the neck problems.
I'm afraid of getting the wrong thing, though. I don't want to buy a monitor made for Macs and then find it is "not for G4," or works fine for internet and word processing but iMovie projects look crummy on it. What do people recommend? Thanks for any advice.

Hi Cornelia,
I can give you just some "basic" advice:
for a normal consumer, a TFT (flat) monitor is as good as a CRT (tube); in technical terms, high-budget CRTs are still "better", in meaning of "color proof", but hey, we talk of miniDV compressed NTSC (=never the same color)
iMovie Master Dan has on his excellent website some tipps:
http://www.danslagle.com/mac/iMovie/tips_tricks/6008.shtml
for calibrating monitors esp. for video usage.....
but, as we all know here, the final quality can only be judged on a TV.......
because on tech principal, a TFT has less "flimmer" then a CRT.
a TFT can be digital connected.
see, if your G4 has a socalled dvi connector - if so, get a TFT with same dvi input! means, you work on a straight digital level, no digital-analog-digital conversion.
think about widescreen TFTs (Apple's), think about size (old man as me prefers 19", which has same res as 17" but is just bigger) - me personally prefer as big screens as affordable! (ever seen 2x 30" in reallife?? <sigh>)
finnally: EVERY TFT can be connected to a Mac, by vga or dvi (mentioned above) connector.
happy shopping!

Have compaq desk top, trying to hook up HD flat screen monitor, won't work?

Haave Compaq, desk top, trying to hook up, HD, flat screen monitor, won't work

Hello redheadjennieo,
I'm not sure Apple is going to write drivers for a Windows Operating System, so we may have to rely on the generic drivers.
What model pavilion do you have?
What operating system?
Does the monitor say anything on the screen when it's connected to the computer and you turn it? (e.g. signal out of range, no input, etc)
If I have helped you in any way click the Kudos button to say Thanks.

Using old G5 as large screen monitor for new MacBook

Would I be able to use an old G5 as a large screen monitor for a MacBook or Mac Mini, using a VNC protocol such as ScreenRecycler (or another). If so, to what degree would the G5 OS have to be functional, i.e., if the video card and speakers are OK, but the OS is corrupted, could the G5 be used just as a monitor powered by the other device? I suspect the answer might be that it depends on what's corrupted; if so, how do I determine the G5's capability as only a monitor? Thanks!

In the traditional sense, the iMac G5 cannot be used as a "monitor" because it does not have video input.
I use ScreenRecycler. Here's how it works. Normally, if you use the built-in screen sharing feature of Mac OS X or run third-party VNC server software, you can view that Mac's screen in a window on another Mac (or any computer) using a VNC client program. That's regular screen sharing.
ScreenRecycler acts as the VNC server software, except it creates a virtual second screen and serves it to any VNC client program. You can change the resolution and arrangement of that virtual second screen using System Preferences Displays pane, as you would with any real second display. It is actually very clever.
In your case, the iMac G5 would be running the VNC client program (such as the developer's own JollysFastVNC) and displaying a window that shows that virtual second screen. When you make the program display it in full screen mode, the iMac G5 simulates a second display.
So to answer your question, the iMac G5 would need to be fully functional in terms of the OS, because it has to be running normally in order to run the VNC client program. It is not running in some special different display mode; it is operating like a normal Mac and just pretending to be the second display for another Mac. And it should work well using an iMac G5 because a wired network connection (be sure to use a Cat-5e or better cable) will be at gigabit speeds. You can try the program in limited-time demo mode for free.

Can I use a flat screen monitor with my Power Mac G$?

Can I connect my Power Mac G4 (model M5183) to a modern flat screen monitor? I already tried it with a small flat screen TV which works fine with my MacBook Pro but couldn't make it work with the G4. I only need the G4 for a SCSI slide scanner that I use occasionally, and would love to get rid of the mostrosity of a monitor that came with the G4. I've updated the processor in the G4 to 1 GHz and run it with OS 10.5.8.

Hi Ron, what ports are on the G4's Video card? VGA, DVI, or AGP?
Which Video card?

Connect to VGA-flat screen monitor ?

my ibook G3 (dual USB) has a RGB display, out , I m not sure which adapter to get to have to connect to a standard dell VGA-flat screen monitor ?
second question:
how do you increase screen brightness? it is so dim,have to squint to see screen

It takes a VGA (RGB) cable to connect to an external monitor.

As for the second question, have you tried resetting the PMU? The PMU (Power Management Unit) has control over the backlight function, so resetting it may help.

Adding a Flat Screen Monitor as a 2nd Monitor to an Integrated Motherboard/Video

Hi,
I am using a GeForce 6150SE nforce 430. It is integrated into an MSI motherboard (K9N6PGM2 v2) using an AMD CPU. The motherboard only has one VGA plug. What are my alternatives for adding a DVI plug for a flat screen monitor to run at the same time as my VGA monitor?
Thanks for sharing your thoughts.

onboard unless its a very new skew wont use 2 monitor outs only one so like XFM sead you need a dedicated GPU (graphics card) that supports 2 screens out or greater!
most graphics cards from 2005 onwards support multi-monitor outputs. i always recomend a dedicated card over intigrated anyday, as they have more processing power and better features then the basic stuff on a cpu or intigrated GPU!

Does anyone recommend a flat screen monitor that works well with a MacBook?

I bought my 13" MacBook about 3 years ago and often find that I need a bigger screen for working on some projects but like the smaller portable size of my laptop. I'm thinking a good sized flat screen monitor would work for me, but don't want to drop a grand on an Apple monitor. Any one have luck with other brands?
I'm thinking 20 - 22". I mostly do my own marketing graphics and photography for my business and need to be able to work in Illustrator on a screen I can actually see things on. LOL!
Thanks for any suggestions or reviews.

Can i use my imac as second monitor for my pc / notebook

Without any knowledge of the year machines you have it's impossible to answer that question. iMacs adn MBA's have been around for many years now so we have no idea of the exact specs your machine have. Remember when posting you need to be complete and paint a picture for us as we aren't there to look for ourselves. Your question should be posted something like:
" I have a 2011 27" iMac and a 2009 MacBook Air, can I use the iMac as an external display for my MacBook Air?"
BTW what you are referring to is called Target Display Mode. Apple does support that on some 2009-2011 iMacs. You can find additional information at:

Imac as a monitor for a MacBook Pro

I would like to use my 6 year old Imac as a monitor for my 1 yr old MacBook Pro. Any suggestions as to how to hook this up?

No. I think it was about 2009 that iMacs could be run in target display mode but not earlier.

Using new iMac as a monitor for PC Laptop

As tintinlad says there are software solutions that use VNC connections (link). Hardware solutions exisit but only at Standard Definition TV quality.

BTW, Apple stopped selling iMac G5s in Jan 2006. Your new iMac is presumably an Intel iMac instead.

IMac Display as Monitor for PC

I have an iMac 2.66 GHz Intel Core 2 Duo, 2 GB RAM, OS X 10.6.2 and an old Dell Pentium III 933 MHz which I would love to somehow connect together. I am considering to install Linux on my Dell and use both computers for different reasons. I wonder if I would be able to use my iMac like a monitor for the old PC.
I have come across the following discussions but it seems that they don't cover my case, i.e., an old Dell that does not have a port for a display port.
http://discussions.apple.com/thread.jspa?threadID=2246912
Any suggestions and thoughts would be most appreciated.

Ron-
There are more details here--

--but the basic problem is that you need a DisplayPort signal to drive the iMac monitor. You can convert a digital DVI output (or HDMI which is the same thing with audio and a different physical connector) to DP format with an expensive converter, but there is no way to convert an analog VGA signal to DP format. The cheaper but more complicated solution for a PC with DVI output, and the only solution for one with VGA output, is to replace your video card with a DisplayPort or Mini-DisplayPort card. Mini-DisplayPort has the same signal but a smaller physical connector.
This was not actually Apple being arbitrary: DisplayPort is more efficient and less expensive than DVI/HDMI because it dispenses with a lot of the conversion hardware needed for that format. Therefore Apple couldn't provide DVI/HDMI compatibility without increasing the iMac cost substantially.

Using my iMac as a monitor for Mac mini.

I'd like to use my mid 2010 27" iMac as a monitor for my Mac mini. Is this possible with thunderbolt?

You'll use the thunderbolt port on your mini and connect to the mini display port on the iMac. use a mini display to mini display cable.
