HDMI LCD as Monitor

Searched the forum and found similar issues, but no definitive explanations or resolutions.
Came into a free Power Mc G5 tower, recently, and thought I'd connect it to a 26" Toshiba LCD TV.
The result was "no video signal".
I plugged in a second (CRT) monitor to look at what was happening. The Mac knows there's a Toshiba TV plugged into it, and gives me all the resolution options I could imagine.
But "no video signal", as far as the Toshiba is concerned.
Is moving a video signal to an HDMI-equipped TV more complicated than simply buying a cable with DVI on one end and HDMI on the other?
Thanks.

Not an issue of selecting the proper input. The TV has two HDMI sockets. I've tried them both, and made sure to select them via the TV's menu.
Here's the Mac's video data:

The first "Toshiba" is the DVI-HDMI connection. The second is the DVI-VGA connection--the one that works just fine. And, no, plugging them in separately doesn't do anything. When I have them both plugged in, the computer seems to think it's talking to two different monitors, and I can use the computer (through the VGA connection).
I have tried setting the DVI-HDMI connection to a variety of resolutions. 1280x720 is merely the last one I tried.
As far as the "native resolution" of the TV: don't know. Nothing like that is stated clearly in the TV's documentation, but I'll keep looking.

Use of HDMI (HDCP enabled) Monitor with MacBook

Hi
I’ve been searching the discussion boards to try and answer this but as I haven’t been able to get a definitive answer I will post my own thread (with apologies if I’ve missed a previous response that covers this)…
I am about to purchase one of the new HP w2408h monitors which has VGA and HDMI (with HDCP) inputs:
http://h10010.www1.hp.com/wwpc/uk/en/ho/WF05a/20491-314293-314303-314303-314303- 80644319.html
My concern is that the HDCP will cause an issue when using this with my Macbook. The posts I’ve read so far talk about issues with TVs rather than monitors – does this make a difference?
I would expect to be able to utilise the full 1920 x 1200 resolution, will this be possible?
My plan is to use a DVI to HDMI cable via a mini DVI to DVI adaptor if this will do the job (as a fallback I could use VGA connections, but would much prefer to use the digital signal).
Thanks in anticipation.

OK, so I bit the bullet and ordered the monitor (HP had assured me it would work OK).
Most importantly it does work, exactly as I wanted it to (MacBook recognised it immediately).
In summary, the MacBook is connected via a DVI adaptor to a DVI to HDMI cable. I'm then passing the cable through a passive HDMI switching box (also connected to a PC) which is connected (via HDMI to HDMI) to the monitor.
I'm using the MacBook in Extended Desktop mode with the external monitor running in its native 1920 by 1200 resolution - it looks great.
I am able to flick between the MacBook and a PC using the switching box. When in PC display mode, the MacBook reverts to single screen mode.
I am not using any HDCP encoding (as far as I know).
Hope this info is of use.

From my iphone 4 will I be able to play games like Infinity Blade or even modern combat games through Apple Digital AV Adapter on my HDTV/HDMI LCD-television?

I have a question before buying it...From my iphone 4 will I be able to play games like Infinity Blade or even modern combat games through Apple Digital AV Adapter on my HDTV/HDMI LCD-television?
Will it support or i have to wait for iphone 5!!!

Having spotty luck with it... see my other post in the iphone discussions...
It does work, but only some of the time - it seems to need a kick in the *** though. Sometimes it links to the TV right away, some times it takes some switching between apps or videos in the camera roll, and now for some reason, it takes plugging my wife's phone in first and then swapping phones once her's is recognized and TV output connection made before mine will output signal to the TV.
And it seems to do video only with some apps and audio only with others, and then nothing with yet others. I guess I just expected it to work, given that we both have freshly updated iphones (4.3), good cables and 2 HD TV's to test with...

New Mac Mini, Not so new LCD HDTV Monitor, no mac support

I have been attempting to set up a Mac Mini with a Maxent LCD 26" HD TV I can't get either the RGB or DVI-D input to accept signal. I have purchased DisplayConfigX and SwitchResX_X. Maybe they could work, but I can't get a signal to stay on long enough to change the settings as listed in other posts. I have tried booting in safe mode as DisplayConfigX instructions suggest. But still only am able to see the screen until gear starts spinning with apple logo, resolution changes spontaneously to one that I suppose is unsupported and I get the unsupported display and a beautiful blank blue screen. I tried manually inputting the resolutions the monitor manual lists, while connected with an lcd pc monitor. But I can't get the Maxent LCD TV monitor to stay on. It appears that if I could get the Mac Mini to send this resolution signal to the Maxent I would be able to delete any unneeded settings and that would be it.
Perhaps Tom Fussy can help me.I have been at this for over two weeks now. So I have become super frustrated. Of course Maxentusa.com offers no Mac support. But state that if Mac mini is supposed to work with PC that it should work with my Mac Mini. My LCD TV is about 6 months old I could still return it for maybe a Sharp Aquos, if that $300 dollar more TV would work. I am happy with the Maxent otherwise. Keeping it, and having it work with Mac Mini Is my choice. Of course Apple offers no support for the Maxent monitor and directed me here. This is my first discussion group post. School me if I have not followed the rules completely.

I was able to get the settings for Maxent using Gregory's software to force 640x480. Here are my settings

Your Suggestions on Adding External LCD / LED Monitors to MacBook Pro?

My current work station is a PowerPC G4 Dual 867Mhz with dual 19" CRT displays. I use this for design work (Adobe Illustrator); photo restoration (Photoshop); & online sales.
I was down to my last two CRT monitors, and wanted to perhaps start porting some of the graphic intense work to a faster computer so I bought this MacBook Pro:
http://support.apple.com/kb/SP499
I have not actually had a chance to use the MacBook Pro - it and all the accessories are still sealed - I couldn't afford the down time to set it up.
I am wanting to add a external monitor to the MacBook Pro that would be suitable for detailed design work with accurate color, true blacks, and the ability to be correctly calibrated. Since I may be still doing work on the G4 with software that will not run on the MacBook Pro I'd like to perhaps buy 3 matching monitors , 2 to replace my crt units and 1 for the MacBook, so that I can closely match the design output between the G4 and MacBook Pro.
I briefly tried a inexpensive LCD TV with a PC hookup on the G4 to get some idea of how an lcd would look. The LCD TV had a native resolution of 1440 X 960, which is a 3:2 aspect ratio, but that resulted in designs elements being distorted (i.e., squares look like rectangles). In 4:3 mode the TV did not distort the design elements, but the picture was not crisp / sharp and appeared soft. From what I've read this is because the lcd, unlike a crt, can't correctly emulate resolutions other than the native resolution built into the screen (i.e., its software guesswork). I also did not like the fact than in 4:3 mode it left black areas on the right and left edges of the screen.
I typically work in a 4:3 aspect ratio with a resolution of 1024 X 768, but a higher resolution of say 1600 X 1200 would be o.k. So what are your suggestions as to finding a lcd / led monitor that has a 4:3 aspect ratio? So far I've found limited information on what appear to be old monitors - there's one on Dell's site; for example, that says it has 1600 x 1200 native resolution, but a review also says its the same monitor they've been making for 5 years (besides I don't think I'd like the idea of hooking a Dell into my Mac). Found a few references to Lacie and NEC.
I really don't understand the monitor manufacturers, including Apple, that claim their monitors are for design work, when they don't offer native a 4:3 aspect ratio. How exactly am I to complete designs when circles are ovals and squares are rectangles?

"Take a flash drive with some representative PDF files saved from Illustrator to your nearest Apple Store or Apple reseller and ask for a demonstration using one of Apple's beautiful 27" 2560 x 1600 monitors. It would replace both of your 1024 x 768 CRTs with lots of additional desktop real estate to spare."
1. Well, actually no since I do not have fixed 1024 x 768 crts since crts do not have fixed resolutions. I can easily set each monitor to a variety of other resolutions including 1600 x 1200. Actually the Apple display would be a step down in total working area if I used the largest common resolution of 1792 x 1344 and certainly not worth the extra cost for the space gained if working at 1600 x 1200.
2. Unfortunately the display requires 10.6, which does not work on a G4 Dual 867Mhz. It would not even work on my MacBook Pro that I've not had a chance to use yet as it comes with 10.5. Also, 10.6 drops supports for PowerPC emulation so that means buying hundreds of dollars in new software. I use Apples only, but one thing I hate about the company is what many perceive is their "elitist attitude" toward their users - do they really think most people in the real world have so much money that in order to use Apple's new 27" display that they have to go out and spend more than the display costs on updating their computer and software. I am not a zombie fanboy willing to buy anything just because it has Apple on it.
3. Like most people I do not live by an Apple store or a Apple reseller, even the local Best Buy does not carry Apple computers in their store because the retail space does not justify the resulting sales (not that I would buy anything there anyway as they are over priced). I am really not interested in driving several hundred miles to the nearest store.
4. For a $1,000 I expect a monitor to offer a native 4:3 (1600 x 1200) aspect ratio - certainly Apple knows that this is the preferred working environment of many CAD and graphic users but they chose not to offer this in the display, thus the Apple display is really seems geared toward pop corn munching movie watching consumers.
5. This display is not actually made by Apple, its probably LG or one of their other suppliers.

Powerbook with Syntax Olevia 23-inch LCD TV Monitor

Hi there,
I got a 23-inch LCD TV Monitor from Syntax Olevia and somehow it doenst work with my powerbook.
The thing is when I connected it to my windows laptop, it worked just fine, I should say perfectly instead. Then I tried it on my Powerbook 12-inch, the Mac recognized the display, there was a VGA display on but when I turned the display on, it says 'NO PC SIGNAL'. You know, I'm ****** !
I have been on the phone with Syntax Tech Support for an hour, then with Apple for another hour, they suggested me to do everything try to get it works, everything they could find, everything within thier knownledge.... COULDNT CHANGE ANYTHING!
So the last thing the Apple guy suggested me is post a topic question here, to see what everyone says and if somebody out there has got the same problem, please do reply so, even you got it worked or not, just reply so I can have some experience. It might be compatibility problem but I don't know, not with a monitor I would say.
So here the LCD name and brand:
- Olevia 23-inch LT23HVX by Syntax.
I would appreciate for any answer, I'm looking forward to it.
Thanks all
Powerbook G4 12' Mac OS X (10.4.5)

Hi,
I'm not familiar with that monitor, but its resolution might be higher than your PowerBook can handle. I have a first-generation 12-inch PowerBook, and it seems that it can't run any of the Apple Studio monitors currently being sold. If that monitor can display a resolution of 1024 x 768, try that, as your PowerBook can certainly handle that resolution. Another thing to try is to see if you can find a friend or coworker who has a similar PowerBook (or any other Mac), so you can try connecting the monitor to that machine to see if there is a similar problem. If no Mac can drive it, you would probably have a good excuse for returning the monitor.
Hope this helps,
Ken

Acer - 19" Widescreen Flat-Panel LCD HD Monitor

I have a question about the Acer - 19" Widescreen Flat-Panel LCD HD Monitor.
The link to the product:
Acer- 19" Widescreen
Under "Whats Included" it only says:
Acer 19" Widescreen Flat-Panel LCD HD Monitor
Owner's manual
Does that mean a power cord, and the cord to connect it to your computer isn't included, since its not listed under Whats Included? Or is it just a given that those two things are included, thus they dont waste time writting it out.
Hopefully I can get an answer before this deal goes away!
Thanks

Of course they do
There are no manufacturers that would sell monitors without the required things to run them!
The only exception is printers or television where they always make you buy the cables ...

Gateway 24" HD LCD Widescreen Monitor

Hello,
Can I plug a Gateway 24" HD LCD Widescreen Monitor into my iMac G5 with iSight and get maximum benefit from the resolution of 1920*1200 ?
Thanks,
John.

You should also be aware that the display will be a mirror of internal display and will not provide any additional space.
Apple has disabled dual-displays and only the hack can open that up.

Sound for Dell LCD TV/Monitor?

Thanks for answers in advance. I am sure this has been answered somewhere but cannot find it.
I just converted to the dark side and purchased a Mac Mini. I hooked the Mini to a Dell 23" LCD TV/Monitor. Instead of ordinary computer speakers I want to use the speakers on the TV.
What do I need?

I am running the same setup you are, except its a 19" Samsung TV and I have it hooked up via VGA. Next to the VGA port there is a port labeled "PC AUDIO". This allows me to run a dual sided 3.5mm audio cable from the audio out port on the mini to the audio in port on the TV.
There should be something similar on your Dell, but I am not sure. Look at the back and in the user manual to see what kind of ports there are.
Here are some 3.5mm cables:

Mac mini late 2012, hdmi to Samsung Monitor no signal

mac mini late 2012, OS X ver. 10.9.2, hdmi to Samsung Monitor (S22C300) no signal,
but thunderbolt to hdmi adaptor can work, any fix for hdmi issue?

It would seem that if the Samsung monitor is not waking from sleep, then Samsung has not properly implemented the Wake on Signal that the Mini is sending out. There is nothing unique that Apple would do for one manufacturer. The signal is being sent out and that is why other monitors wake. Your Samsung, and mine, which are both probably different models are not waking when requested by the Mini. The best that can be done is to set the Energy Saving System Preference to not put the monitor to sleep. Use the Screen Saver as desired.

I have an older NEC MultiSync LCD 1700V monitor. I'm having trouble getting it to work with my MAC BOOK Pro with Mavericks. Is the monitor outdated?

I have an older NEC MultiSync LCD 1700V monitor I used for my MAC Power PC G5 (with the Tower). I am discarding the G% and have tried to connect to the laptop MAC BOOK Pro using the 15 pin dongle for connectivity. I get the screen with the desktop and icons, but I cannot get any applications or folders to come up on the screen. Is the monitor just outdated for the newer softward, or isk there some fix?
Please advise.

10.9 Mavericks changes the way displays are treated, and the new default is that each display is an independent workspace. This can be put back to the "correct" Extended Desktop way.
Windows in Mavericks reside in a single space by default, so they usually don't span multiple displays. When a window is dragged between displays, it appears translucent on one of the displays to indicate this. After you are done dragging the window, it snaps to one display.
If you need an app window to span multiple displays, deselect the option "Displays have separate Spaces" in the Mission Control pane of System Preferences.

HDMI to (2) Monitors

I am trying to split a customers Mac Mini to 2 Sony LCDs. I have converted VGA to HDMI and it works fine on both sets if independent. When we go to a one in two out HDMI splitter it will work until the Mac downloads new update and restarts or goes to sleep. You then have to manually unplug both HDMIs to resync. Is this a Mac issue, HDMI, HDCP???Can anyone help?

Any answers? I a similar question. If theres any way to connect my MacBook Pro into 2 monitors. I'm using right now just one.

Using the mini DVI - DVI cable with HDMI LCD screen?

Hi,
I bought the apple mini DVI - DVI connector to connect my imac to the back of my plasma. I have a 3 meter DVI cable to extend the mini DVI - DVI connector.
It worked fine but the plasma is not so good for my purposes as i am using the set up to display images.
I have just bought an LG LCD TV for a very good price.
However the LG LCD does not have DVI socket! It has HDMI.
Is there a cable available that is DVI (female) - HDMI?
And will this work in theory?
Any advise is much appreciated...
Thanks

Hi Network 23,
Im not sure what you mean exactly?
Which adapters and cables are you using between TV and Mac?
My PowerBook and MacBook Pro have a DVI port, so I start there. I guess you're starting from the DVI port at the end of your adapter cable. At this point we both start from a standard DVI port.
From there I attach the DVI-HDMI adapter I linked to earlier, and then between that and the HDMI port on the TV, I use a simple, inexpensive HDMI cable also bought at monoprice.com. While you could also use a DVI-HDMI cable, I chose to use a DVI-HDMI adapter so that I could use standard HDMI cables, since I anticipate buying more HDMI components in the future.

Why does a DVI or VGA look better than HDMI for 2nd Monitor

Why does a DVI or VGA connection for a program monitor look better than HDMI. I've tested this on several systems with CS5x and CS6. The full screen output from premiere definitely looks worse with HDMI.
I can often see visual differences with the Windows GUI as well, over sharpening of text and lines, harsh rendering of gradients. It looks like a VGA signal displayed on a television.
I've looked at the NVidia stetting and it appears to be set to 1920x1080 at 60hz either way, DVI or HDMI. On one Acer 20 inch monitor the was VGA, HDMI, Composite, Component, and Digital Tuner, but no DVI. The program monitor has always looked blah from the HDMI. So I recently switched the connection to a DVI to VGA adaptor, and now the video looks so much better.
Any thoughts or explanations?

Just because the monitors accept a 1080P signal doesn't mean their native resolution is 1920x1080. At 20 inch they very likely can scale that signal down to the native resolution of the panel which may be 1600 x 900 or another resolution that is 16 x 9 resolution. That scaling can be done by the GPU or firmware on the Monitor depending on the video driver options and the firmware options. That scaling is also the most common cause to text and icon blurriness you are talking about. As an example there are Pro monitors that accept a 4K signal but scale it down to 2.5K or 2K on the actual panel. You might try going into your video card settings such as Nvidia control panel and look for the scaling options. Select GPU scaling and see if the preview is better. If that doesn't work select no scaling and see if it's better if the monitor firmware handles the scaling.

MacBook hdmi lcd display - help needed!

Hi all, I'm connecting my MacBook to my 32" Vizio lcd via hdmi (using a mini-dvi to dvi adaptor & dvi to hdmi cable). When I mirror displays, one of two things happen: (1) either the Vizio display is too small and has black bars around it, or (2) the Vizio display is too large and I cannot see the menu bar or the dock.
The fist time I connected to the tv, I managed to get the full screen display perfectly but have not been able to repeat this since. I've tried everything I can think of - different combinations of resolutions, with and without overscan, etc.
Any advice much appreciated!

Try this:
Hook the MB up to the Vizio.
Hook the MB up to it's Magsafe power adapter and plug the adapter in.
Close the lid on the MB so it goes to sleep.
Now, plug something into a USB port on the MB.
The recommended thing to plug in would be a USB keyboard and mouse. But you could use just one of those, meaning either a keyboard or a mouse. If you don't have a USB keyboard or mouse, you can just plug in one of those USB flash memory devices.
The USB activity will cause the MB to wake up with its lid down and only the external (Vizio) screen will be active. Once that happens, you can lift the lid on the MB and use its keyboard and trackpad and the built-in screen will stay off.
