Regular Cheap CRT TV as Monitor

I searched the discussions and there was so much technical information I just got confused. I am just not up on TV technology, I guess. I am looking to buy an Intel Core Duo. I think it will end up with Windows as well as X.
If I go to Wal-Mart or somewhere like that, and get a basic, cheapo CRT TV, 27" or something, with the hookup ports in the front, will I be able to use it with a Mini? Would I also be able to use it as a regular TV? With satellite or cable hookup? What about also using it with a PS-2 game system? Would any of these uses interfere with any other uses, and if so, how?

Hello,
Standard televisions make terrible computer monitors. They don't have the same resolution that monitors do. So, the images lack detail and crispness.
It's generally tolerable for short periods of time. But, text will look terrible (if you can read it at all).
Now, if you got a television that was a high-definition television with HDMI / DVI inputs, then you could use that interface to get a nice and clear computer screen.
Otherwise, you'll be best getting a cheap monitor and using the television for just watching television and playing games on the Playstation.
I hope this helps.

Adding HD CRT TV as monitor?

I have a Powermac G5 I am using to edit in Final Cut Pro using High Def footage. I just bought an LG CRT HD TV/Monitor. This was to replace my current 23" Apple Display as my #1 monitor. The trouble is that the resolution options offered for the new LG are MUCH lower than what are offered for the old (not HD) Apple display?
Any help here?
Thanks,

That's what you get for buying an HD CRT TV. A monitor will always have a MUCH higher resolution than a TV, even an LCD TV or CRT TV (even if it's a HD TV). Go back to your 23" monitor. It will display HD better than any HD TV.

17" CRT Apple Studio Monitor

Unfortunately, I bought a Mini without knowing that my current monitor is unsupported. Are there any work arounds? Has anybody successfully used a 17" CRT Apple Studio monitor with the mini.
Thanks in Advance

You may buy a "DVI to ADC Adapter" from apple.
Yesterday I've bought a Mac mini and I already owned a 17" Studio Display in conjunction with the DVI to ADC, but the "sleep button" on the display is not working.That's why I'm searching this forum.

B&W 17" CRT Studio Display Monitor

I have this connected to my G5 P/Mac which works fine.
At present it is powered through my old G3, can I power the monitor directly through a power lead to the mains supply?
I think the power lead from the G3 might do this?

It sounds like the monitor is re-calibrating. When you re-calibrate an Apple CRT the monitor goes though a self analysis and flashes solid colors on the screen. (Other brands are not as tightly integrated with the Mac OS so you must do this by hand, er... eye... er... whatever.) What OS are you using? I know there was a setting in OS 9 & OS 10.3 to re-calibrate automatically periodically. Check the Monitors/Displays control under “color.” I always switched off that feature and re-calibrated when I had a free moment.

Seeking a CRT, 1024/768 Monitor...

I have an aging 9 yr. old Sony Trinitron 17 inch which works great on my new MacMini; however the monitor needs to be replaced due to white dimming and contrast is slipping so letters are not as crisp. I have tried twice to get new monitors but they have distortion problems unable to give a true squared off display like the Sony. Yes, I used all the OSD settings to wrestle the monitor into shape, so to speak. But they also show inconsistent white color across the display.
I am now in process of getting replacements from the Viewsonic and Lenovo. Hopefully they will work better. I really need a monitor that is accurate for color and shape and bright. I am tried of spending funds and returns. Please, I need to know why the Sony works right and the others wont. I am a legally blind guy (hence the low res) who enjoys doing graphic design so a correct monitor is important. I love my MacMini, now it just needs a good display. Help!

The problem with LCD displays is that by the very nature of LCDs, they are, essentially, fixed resolution. That's why they each have a 'native' resolution at which they work best. Unlike a CRT where the screen is a continuous coating of phosphor, and each dot lit by a scanning beam making it possible to switch between all available resolutions with no incremental degradation of sharpness, LCDs screens are comprised of physical 'dots' (the LCDs themselves in fact). The number of LCDs dictates what the native resolution is - for example, a 15" panel has 1024 LCDs horizontally, and 768 vertically. 17 and 19 inch panels have 1280 horizontally by 1024 vertically.
LCD displays can operate at lower resolution than their native settings, but in effect only by interpreting the signal, which along with the fact that then the edges of objects don't correspond to the exact edges of the LCDs themselves, gives the edges that fuzziness.
Many people with significant visual disability are left with the choice of buying very large LCD screens in order to get a usable image or hunting for the few remaining CRT screens. Some of the LCD manufacturers, aware of these problems, have been working on improved displays which give sharper results below their native settings, (and LCDs have been steadily improving over the years in this respect too) but even the best are still relatively poor compared to the sharpness achievable with a good CRT.
LCDs with DVI really are a significant improvement though, because DVI enables the system to communicate with the display without 'translating' the digital signal inside to the computer to analog signal for use by the display. That process of translating it causes degradation, which results in less contrast, lower brightness, softer color and less crispness. A DVI display will therefore look much better, because it is sharper/brighter to begin with and while it will still suffer fuzziness when set below the native resolution, will give much better results than an equivalent VGA device.
Sadly though, it's LCD technology itself which is the cause of your problem, and it may well be, depending on the degree of impairment and your particular sensitivities, that a CRT will be the only real solution. I'd recommend you have a look at good display models such as the Dell Ultrasharp range before you give up on LCDs, though these may well be stretching your budget.
As such, it might be a better solution, certainly for the short term, to find a used CRT with relatively little use, and which should be quite inexpensive, thus giving you time to look around for a good LCD, and for prices of high quality LCDs to drop a little more. I know that many companies have been throwing often very good quality CRT displays away over the last couple of years as they have upgraded to LCDs, so there's been no shortage of used ones around - often free if you know where to look!
You don't say where you're located, but you might find there's a local center in your area offering specialized help and support for the disabled and which may be able to put you in touch with sources for such things. I'd start by contacting your town/city hall to see if they run such a place, or know of one. Alternatively, your doctor may know.

MacPro - Dual monitors - to link to older CRT 4:3 monitor / tv

Hi
I didn't know where to post this, so hopefully I've come to the right place.
I have a 2008 Mac Pro, and dual DVI monitors. I have lots of older VHS tapes I want to edit and want to preview the edits on an older CRT monitor / tv I have lying around at home. It has a scart and RCA connections on it. I also have a canopus advc 300 which I use to transfer video through to my mac.
Is there any way I can link the old monitor for previewing clips as my existing computer monitors are widescreen.
Thanks in advance.

CRT vs Lcd monitoring

Believe me, I've been struggling with this question for years.
For long I felt CRT monitors were better than Lcd monitors for critical color correction. But feeling the current push in Lcd technology, is the acceptance for professional LCd displays such as the JVC 24"HD ok, or do the people with the golden eyes only see the bvm CRT as the only way for critical color grading?
Knowing I usually color 1080 24p.
If you make a good living coloring, I really would appreciate your comments.
- Eric.

Someday I will be done with this question.
CRT technology fails for a number of reasons over a certain display size, and it is for those reasons that the technology is no longer acceptable,both for the technical and economic challenges. At 24", it is almost not worth the justification for HD in any sense, since that technology really only starts pulling away from what went before it at maybe 36" and beyond.
In years past, the JVC LCD's may have been competitive in terms of rendition, but suffered from massive off-angle viewing problems. It is spectacularly difficult to build a decent LCD -- if you find one in a "reasonable" price category, +caveat emptor+ -- its a $38 Rolex.
Some of the recent plasmas are pretty good. Some high-end post facilities are actually using them, but have conditioned them behind LUT-boxes like Truelight's Northlight system, among others, and have a crack staff of technicians on standby with probes in hand -- and do routine daily/weekly checks, lineups and calibrations. Most of the time, its to make sure the monitor is displaying the AIM values of the day for the associated lab, but its also because they just wander, and not just over time, but with the intensity of the picture that happens to be up.
Consumer TVs are for folks at home to kick back and watch Glee or whatever, or ignore it altogether just to have enough noise in the background to cover what's going on in the foreground.
So if you're making video that people don't watch anyway, LCD is great, and doesn't cost very much either.

Can switching from CRT to LCD monitors cause system problems?

My 9.1 locks up periodically (but the cursor still moves) since I replaced two 20" CRT monitors with two Samsung 19" LCD monitors. Could this affect the performance of my machine? I've tried everything else to address the freeze problem but recall the issue started when I installed the LCD monitors. Anything I can do?

Studedot,
You may have issues with the amount of video memory depending on the resolutions of the new LCD screens.
I find LCD screens go up to insane resolutions, way more than the corresponding size CRT monitor, ie. a 17in Dell LCD monitor with higher resolution than a 21in CRT.
It shouldn't cause crashes or freezes, but may cause -redraw problems when closing / moving windows in 2D and playing 3D games.

Looking for cheap but good second monitor

Hi all, I use my Mac Pro mainly for recording/mixing music. Looking for a new, smaller (15''-17'') seccondary monitor for functions like MINI editing, plugin tweaking, etc. Any recommendations?

Try EIZO monitors, good value for not so much money.

EMac CRT Monitor Life?

Just wondering what the average life I can expect out of my eMac CRT Monitor? I've read that the average life of a CRT monitor is about 10,000 - 20,000 hours.
Since I purchased my eMac in Jan 2003, run it about 12 -14 hours a day (figuring in screen saver mode), 7 days a week, 12 months a year, that's about 4700 hours a year (+/-). If average screen life is 20,000 hours, that gives my eMac monitor about 4.25 - 4.5 years of use before it reaches it's end life.
Does this make sense, or is the life of an eMac monitor much longer than the 10,000 - 20,000 hours I've read about on line (between CRT and LCD monitor life)?
Any input would be greatly appreciated.

Interesting because my eMac will sometimes get a
"spark". Kind of hard to explain but it will make a
zapping sound and loose a screen for about half a
second - like it's trying to crap out on me.
It doesn't do it all the time. Someone told me that
my CRT is trying to die.
All the electrical has been checked out and I've got
the computer hooked into an APC.
Any ideas??
Dolphin, I posted this same question few months back with no replies. I forget how long this has been going on --the Zap! Blip!--- but my warrant is 3 year warranty on my 3 year old eMac is bout to run out.
If it is a power surge it never affects aany other elctrical things it my house so I am very suspicious of the eMac itself.
Thinking I will not go for anohter warranty hope for best and invest in mini-mac if the eMac does bite dust after warreanty expirres.

Monitoring HD through HDMI

Hi All,
I am busy cutting HD footage that I'm monitoring through my BX (broadcast) monitor HD-SDI and my client has a large Plasma screen that he is viewing off, which the tech guy cables in off the HDMI signal from the BlackMagic Multibridge box. Obviously the BX monitor is clearer and crisper, but I was wondering if any of you could enlighten me on using HDMI...if any of you do use it and/or if I shouldn't even consider it. I for one will use the old CRT broadcast monitors for as long as possible but would love to know what you all are doing.
Thanks so much,
Cheers,
Susan.

I don't even know of any broadcast monitors which can be connected via HDMI... only consumer displays as far as I know... Can say though that a Panny or better yet a Pioneer plasma can be dialed in black level wise much better than cheaper plasmas for client monitoring... I use a 23" CD for my own ref monitor with an MXO in the mix. Can't afford a CRT HD around here... and it works great for grading as long as you keep an eye on the scopes. The CD just doesn't display black... it's sort of dark dark gray.
That said, the eCinema displays are nice... but pricey.

What external monitor??

I need to come up with the specs for a few edit stations. Need to do both DV and HDV.....so...
For HDV I am thinking a Powermac (be it intel or G5-not installing for a while) with two 23" screens (although perhaps one will be a dell 24" so that we can play back from the HDV camcorder direct)
For DV I would have in the past specified a external monitor to chain to the DV cam or deck and my understanding was that one should use a CRT because they run a different colourspace. Does this still stand now that home televisions are becoming LCD? If we run from dv deck into the video input of the Dell will that do? Dont have the cash for a proper broadcast monitor (or the space really)
I assume that there is no reall need for a HD output card if working HDV? Anything I should consider adding? The G5 would be pretty high spec for motion and things too.
Cheers for all advice!

hear are our findings, they are personal but represent comments from hundreds of clients watching the output from FCP
We have a choice of a number of LCD computer displays from many manufacturers varying in size from 19" to 42" We colour manage the displays using a custom ICC profile.
We do not use LCD displays for the following reasons:
we can only watch the displays for a few minutes at a time due to the distracting effects from the displays
the colour space of an LCD is extremely poor in relation to a CRT and does not produce natural looking colour
pixelation on the image is very noticable and is unacceptable
a cheap CRT TV is much more preferable than looking at a very expensive LCD of any size especially at close viewing
A compromise would be using an LCD or plasma Television as a monitor, but close distance viewing is not recommended and the colour schemes they produce although pleasing are highly processeed by the electronics and can not be relied on.
In the UK, all broadcasters and all the facility houses we deal with ban the use of LCD computer displays for monitoring output video for the above reasons.
It would be interesting to hear other viepoints

Want to use iMac G5 LCD as PC monitor

Hello, here is my problem:
I have iMac G5 that I can't use it (logic board problems, can't finish OS installation) but LCD works just fine! Inverter works fine too.
I want to use iMac LCD instead of my regular (still CRT) monitor.
My question is: is it possible to cut off THIS side of LVDS cable (cable that connects logic board and LCD) and instead that little 30-pin connector put DVI connector so I can connect VGA/DVI output from my PC to that (new) DVI connector that goes into LCD? I hope you understand what I want to do!
If someone has other idea how to use iMac G5 20inch LCD like PC monitor, please post it.
Message was edited by: TDKZG

I also would like to try and do the same thing.
I have a g5 imac ALS... just had the motherboard recapped and power supply replaced. It works but freezes up intermittently and the fans are just insane...throttling up to max every 30 seconds for a couple minutes fo no reason (temp is ok), the last time I turned it on I realized that it has become pretty much unusable as a reliable family server. We keep the computer on our kitchen counter and the smaller G5 fits well and matches a whole lot better since it's white.
I don't mind cutting or soldering...is it possible to tap into the main cable? It would make a sweet pairing with a new mac mini.

Monitor not recognized by Mac anymore?????

Hi
This is big and what is APPLE doing to solve this issue??
I just copy some posts from the forum to show how big this issue is, there is 8 more pages with the same problem, and i am one of them!!!!
HELP!!!! WE ARE FREAKING OUT HERE AND NEED A SOLUTION!!!
Yes, me. I have an HP w2207 who worked with my 3 y.o. old MacBook (OS 10.4.??) via the DVI-port flawlessly. Then bought a brandnew MacBook Pro with 10.6.X and the external monitor stopped being recognized. It works now that I have changed the connection to the VGA-port of the monitor (and bought yet another adapter for the MacBook Pro) but the quality is not what I'm used to.

Yes. I've tried 7 different Macs including a MacBook Pro with Snow Leopard (10.6.2) and my external monitor doesn't work with it either.
For me here's a recap:
Installed SL on a Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #1 and now that input no longer works with Mac computers.
Reinstalled 10.5.8 on the Mac Pro and HDMI #1 still didn't work, so I plugged the Mac into HDMI #2 and it worked.
Reinstalled SL on the Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #2 and now that input no longer works with Mac computers.
Since then, every device (PCs, DVD Players, Video Cameras, etc...) I connect to either of the HDMI inputs work fine. However, neither HDMI input works with ANY of the 7 different Macs (regardless of OS version) I've tried, except for a 10-year-old G4 running Panther or Tiger.
The monitor had previously worked with the MacPro (HDMI input #1) and a G5 (HDMI input #2) for almost 2 years.
When I plug the MacPro into any other monitor via HDMI, it works fine. Same thing with the G5.
My theory is still that the installer for Snow Leopard somehow made my monitor's HDMI inputs incompatible with Macs. I'm so frustrated that I'm ready to buy a new monitor, but since there's no guarantee that a new monitor won't be adversely affected by Snow Leopard, I'm still dubious.

Another "me too" post...
Not sure exactly when it stopped working (since I don't use it every day) but my Viewsonic VX2455wm stopped working with my MacBook recently too. Checked with another MacBook (six months newer than my Late 2006 model) and that exhibited the same problem. Both machines have fully patched Snow Leopard installs. Both started with Tiger. Mine is regularly connected to the external monitor, the other has never been connected. I'm connecting using a DVI cable and a mini-DVI-DVI adapter.
The monitor appears to work correctly. I've checked with a Windows laptop connected on the VGA port. I want to test with another DVI-enabled machine to see whether or not its the cable.

Hi Guys
I have the same problem with my new Dell 2209WAf. It worked fine before i changed from L to SL.
I didn't know what happened so i have spend hours and hours to resolve the problem.
Hours with Mac support and friends didn't change anything, i still cant make my Dell to work, or show up in preferences. I am working as a photographer and this issue is a real problem.
I just heard from Mac Support that Apple is working on it.....well, doesn't help us with the problem today.
So Apple, DO SOMETHING ABOUT THIS! NOW! this problem should NEVER showed up, this is something you should have fixed before telling all the Macers to upgrade!!!

Experiencing the same issues. However, on bit different hardware.
I'm using the XLR8 ProView USB input devices. Using these devices on a mixture of 10.5.8 and 10.6.2 systems (2 MacBooks, 2 Mac Mini and 1 iMac).
I can confirm the following:
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.6.2 no video is sent to the mini-DVI device (inputing into the XLR8).
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.5.8 video is sent to the mini-DVI device (inputing into the XLR8).
Let me also state, that the mini-DVI port on the Mac Mini's do work. They have been connected to 19" monitors and working without issue. Today, the mini-DVI devices were replaced with minidisplay port devices, which are use in conjunction with the mini-DVI ports.
It would appear, in my case, that the problem is that the mini-DVI port on both the MacBook and Mac Mini, running 10.6.2, as a secondary display device is not operating properly.

Same problems here. I reloaded OS 10.4.6 which is what shipped with my MBP1,2 17" 2.16 Intel Core Duo 2GB ram and after installing that, i was able to select 1920x1080 for my external HP w2338h, DVI-VGA, never been able to connect DVI-HDMI. On SL, the max rez I was able to "use" was 1600x1200 which looked horrible. So this leads me to suspect that this must be an issue with SL.
I spoke with Apple Tech support on Sat and was no help. The only suggestion was that I take my MBP and Monitor to the Apple Store. Those of you who are fortunate enough to live in Chicago in the winter, then you know that option really isn't that feasible, it is but just a giant pain.

I have an iMac 9,1 Intel Core 2 Duo that I bought last June. It came with Leopard, but I upgraded to Snow Leopard. Currently, it's running 10.6.2. My HP w2207 Widescreen monitor works perfectly with it using the DVI port on the HP and the mini-display (not mini-DVI) port on the iMac.
However, I just bought the top-of-the-line iMac 11,1 Intel Core i5 QuadCore three days ago and it crashes nearly every time that it wakes from "sleep" when the HP w2207 is connected to it. It doesn't even recognize that the w2207 is connected to it. Additionally, when the w2207 is connected, it (a) looks terrible - very dim and very granular, and (b) causes the iMac QuadCore to operate very sluggishly. When I disconnect the HP w2207, the iMac QuadCore is lightning-fast.
Much like my older iMac, the QuadCore is running 10.6.2 and I'm using the mini-display port.

Another me too post. I have a new 17" MacBook Pro with 10.6.2 installed. Trying to connect to an HPL2245wg - sometimes it works flawlessly - other times not at all. Some mornings I spend 30 -40 minutes rebooting, unplugging and plugging the monitor, Detecting Displays, changing the Graphics Card (Energy settings) - all to no avail. Very, very frustrating Apple - please figure out what is going on with this issue....and get it fixed!

Wow, me too. Did a minor software update (apple released it) last night, got on this morning and BANG - my main 24" Dell display is NOT working.
This is ******, apple have surely f**ked up here. It's never had a hitch, ever, since i bought it 9 months ago.
We are all reporting the same thing - software update, and then no working external display...

I seem to have found a fix for myself. I was having terrible issues with the screen blinking and flickering constantly. I tried to reset the SMC with everything unplugged and the computer would not reboot at that point on it's own which led me eventually to reinstalling SL.
Reinstalling SL is quite painless actually as it installs on top of your profile. After reinstalling I ran software update which installs the cumulative upgrades. Now I usually don't have any problems but must follow the instructions to run in clamshell mode to the letter.
After a week of running in clamshell mode I started having an issue with the dock not lining up so I put the computer to sleep, disconnected the monitor and restarted with nothing connected. After that, followed the clamshell mode instructions again and have been working fine again all week.
I've also disabled my screen-saver, and deleted the windowserver preferences as part of my debug process but not sure if that has contributed to my new found stability.

Me too. I have a MacBook Pro 2,2 running the latest Snow Leopard 10.6.2. After I have installed yesterday's security patch it does not recognize external displays on the DVI port any longer. Tried it with a 23" DELL at the office and a 23" Samsung at home. Both have worked without any problems for years.
I am curious to learn how this behavior is related to security...

I want to use multiple iPads as external monitors from a PC using the iPad VGA adapter (wired)

I want to send a VGA signal to a couple of iPads using them as monitors. I currently use a pair of regular 13" VGA 1024x768 lcd monitors looping thru an LCD projector displaying the same signal sent to the projector.
I want to use the iPad VGA adapter and WIRE them in just like a convention LCD monitor. Yes there are apps like air display and others but they don't allow cloning and have latency issues and must be networked. I need an app to use the VGA adapter and actually wire them in using a VGA signal from my existing VGA distrubution amp.
The size of the iPad is perfect for my application however I cannot find an app to let me send a signal into the iPad via VGA adapter.
Any ideas?
thanks,
the Sherm
