I am aware of the hardware differences between these two types of displays, and in a word that CCFL will have less color shift producing more accurate colors (In theory).

However, this information has been gleamed from old forums/posts on the topic where CCFL was produced and LED was far from what it is now.

In 2015 (now) in regards to the availability of high end monitors is CCFL even worth considering? Taking into account price/features such as 4k 2k 144hz etc that you can find on LED monitors and the advancements made in the last 3-4 years alone.

To clarify, hypothetically if I were to have a LED display from 2011 and was considering purchasing a new monitor. Would the money be better spent purchasing a slightly older broadcast level CCFL or a consumer level high end display?
 
It is my understanding that RGB-LED Backlit screens are leagues ahead of old CCFL, wheras White LEDs have their pluses and minuses.

Do you mean colour shift through aging?

I was wrong, in fact it seems to be the opposite of what I had stated, and CCFL requires more frequent calibrations.

" Aside from the longevity difference, high quality CCFL displays do not suffer from the problems you describe. In fact, some of the best monitors intended for high-end image and graphics editing have CCFL backlighting. CCFL backlighting offers some inherent advantages over LED backlighting such as wider color gamut and better color quality. LEDs are slowly catching-up but both Eizo and NEC continue to offer high-end CCFL displays."


But again, that post is from 2013.
 
Backlight aging is a case by case thing.

My CCFL c-PVA monitor is rated for 50K hours and the white point has barely budged an inch over 11K hours.

LED aging is also very dependent on their operating temperature but as for colour shift in different designs, I don't know too much.

A lot of the latest W-LED monitors cover more than sRGB such as with http://forum.luminous-landscape.com/index.php?topic=100948.0
 
The 'professional' CCFL back-lit IPS panels use very grainy, film grain inducing matte coatings, especially the 27" 1440p and 30" 1600p panels which are completely worthless compared to what is available now. The only note worthy CCFL back-lit monitors are the NEC 2490 with an A-TW polarizer and glossy TN panels like the Acer G245H, 120hz Asus VG236H and HP 2509B which have better colours almost all of the TN panels which have come out since.
 
NCX,

After all these years, when has AG coating caused a real issue? Even the roughest IPS coatings were good enough considering the PPI.

It's so down on the list of important factors for a monitor. I'll never understand your fixation with AG.

I'm with NCX on this. For me it is one of the most important factors when deciding a monitor. I can't abide grainy screen surfaces and for those that can: "good for you". Not everyone is lucky enough to let such an obtrusive thing escape their notice.

I have never seen a CCFL backlit display which has not become progressively more yellow over time.
With CCFL backlit displays, I had to calibrate them at least once a month.
With all of the LED backlit displays that I own (white LED) there has been less change year-to-year as there was with CCFL backlit displays month-to-month.

If you have a professional display, it's possible that the backlight drift is being compensated for, and I suppose how long you are using the screen is also a factor. But I'd never consider buying a CCFL backlit screen again.
 
I think only if you need wide gamut then you may consider ccfl, to avoid gb-r uniformity issue. I don't know how good eizo compensation tech is since I can't afford one, but they may able to mitgrate all the issue with better pick panel and compensation.

Ccfl does age, my 20k hour ccfl when calibrated using my own sprctro correction profile vs correction profile come with i1d3 have a color temperature difference around 500K. The ccfl panels in my laptop age way faster though.

Because there is a panel... and they stick a horrible coating on it between you and the perfectly good panel under it, which reduces glare obviously but other than that makes the image quality worse.

The newer screens with "light" coatings are alright though, but I would still prefer a glossy screen, for the durability as well as nicer colors and better blacks.
 
Monoprice and some Korean brand sell some new 30", probably old panel stock. several retailers still sell nec and eizo ones aswell.
 
Soon Quantum Dot (QLED) backlit monitors will become available, might even replace the current GB-r/RGB/MG-LED panels eventually.
Maybe they are easier on the eyes especially because they are very good with red light. They should also be cheaper to manufacture.
A Philips monitor should be out soon and panelook lists three AUO panels as wide-gamut QLED

These are not QLED displays.
These are displays which use blue LED backlighting with a quantum dot enhancement film (QDEF) to convert that blue light into very pure red, green, and blue light.

Nice to see that there are higher resolution IPS-type panels using this technology on the way.
I wonder how long it will be until there are high-end displays using them. Unfortunately they all appear to be 60Hz.

On another note, how much should one be expecting to pay for a high end reference monitor?
I was originally making the assumption it would be between 1-2k. Keeping in mind the display is WUXGA

Yeah, and then there is this whole "LED produces too much blue which leads to early blindness" thing as well.
Two evils, and there is no lesser one.
 
What kind of monitor do you want? CCFL back-lit monitors are irrelevant since almost all of them aside from the ones I mentioned above (the 60hz glossy TN panels I mentioned above are only relevant when compared to current TN panels since there are a few PWM free glossy 23-24" LED back-lit IPS available now) are easily outclassed by LED back-lit monitors made in the past three years. There are some nice 'professional' LED back-lit monitors with essentially grain free matte coatings (NEC PA series), but they glow far more than the non-wide gamut options and the glow free 'professional' wide gamut monitors (Eizo CG & CX series) use grainy matte coatings.

Is removing the anti glare coating from the monitor not an option?

Yes it is just about possible if you don't mind buying a £1000 monitor and instantly voiding the warranty and potentially ruining the screen as the same time, also with no coating the screen will be even less resistant to dirt etc.

I wouldn't risk that with an expensive screen... maybe a cheap Dell screen or something, but unless you are a millionaire and loathe any sort of AG coating I don't think that is a good idea.
 
I am yet to see a decent LED backlit monitor where text is readable and doesn't hurt eyes after several hours of staring at it. So far all the WLED backlit VA and IPS panels with or without AG coating were terrible - those without AG coating were totally unusable. I have no idea where one has to live to adore AG-free monitors. I presume basement is the only location where it's possible to work on those ;)

I am yet to try a monitor with RGB-LED backlight, because simply staring at blue glow is not what I expect from a good display.
 
Glossy hurts my eyes more than mate
WLED is unusable for me, im not sure if it is wled spectrum

Flicker free does not provide any benefits for me it seems
There are only few CCFL TN's left on in my country, there are no CCFL PVA/IPS available. Basically starvation and fasting, only used monitor that fit my eyes left

I'm just like you, I just can't stand w-led displays. I have to calibrate them below 6500k to get rid of the bluish tone, and still I can faintly perceive it.

W-led is the worst thing that ever happened to displays since the invention of the lcd panel panel in my opinion.

I think my next monitor is going to have a gb-r backlight.

Glossy monitors are also horrible, the whites on a glossy display look like mud and the colors are too saturated under the light.
 
What monitor should I buy now? CRT or CCFL? :D

Or should I wait for OLED?
 
RGB oled's, like the ones developed by samsung are definitely better in this regard as in they have a more even spectral distribution between blue green and red. I've tried the tab s2 and in the reading mode, which is around 5500k, the whites look yellowish, with no hint of blue.
