LED vs LCD monitors for PC

[alegator]

Hi, I've been using a Viewsonic VP230mb 1600x1200 LCD monitor for my PC in the last 11 years. Now I'm planning on purchasing a Samsung LED HDTV 24in 1920x1080 Full HD 1080p, which I will use both for TV and the PC. How does the image quality of my Windows XP PC (or Windows 7) compare on these monitors? Will the LED be better than the LCD? Thanks

LED is the light source. It's still an LCD. It's a "LED LCD"
The non-LED LCD is lit by fluorescent (CCFL).

The Viewsonic VP2365-LED would be much better than the Samsung:

The Samsung is TN tech. The Viewsonic is IPS tech. IPS is accurate color, TN is crappy and cheap.

Amost all LED monitors still use LCD technology to produce the picture. The 'LED' refers to the white backlight rather than pixels. Your older LCD will use fluorescent tubes to produce the backlight which is a little less efficient and occupies more space. Of course the newer LCDs are better than the old ones but the biggest difference you will notice is the monitor will be thinner, run cooler possible have a more uniform back light area.
There might be a slight improvement in contrast becase LEDs are very fast to react to changes in their drive power so the monitor electronics may adjust their brightness in accord with the picture content, This means bright scenes may have a brighter backlight and dark scenes have the backlight reduced and hence look darker. Rapidly dimming the old fluorescent backlights wasn't possible for technical reasons.

The only 'real' LED monitors are OLED based and VERY expensive at the moment.

I cannot believe you had an LCD monitor last that long. I've never had that happen with any I've bought. But then again if you bought it 11 years ago you paid a small fortune for that kind of resolution so at least you got your money's worth.

Out of couriosity, I went to Viewsonic web site and found this..............

Proving again that ViewSonic is an industry leader in providing quality and tremendous value, the estimated street prices of the VP230mb and VP201mb are $6,235 and $3,295, respectively. The new ViewPanel® displays will be available through authorized ViewSonic resellers, distributors and mail order catalogs beginning in late July, 2001.

Talk about a markup! I'm surprised the CCFL backlight lasted 10 years.

As for the Samsung, it has good specs and the LED backlight should last longer than ten years. I have read bad things online about the power supplies Samsung uses and their quality control leaves a lot to desire.

Thanks lordmsurf and betwixt for such useful info. As you can see I was out of the market for a long time and was unaware of the technology behind LED screens.

Hi jman, I got this monitor as a gift on December 2001, so it's almost 11 years old. Back then, it was purchased brand new for $3500. I've been always very strict with powering the monitor off when not in use, so that helped. The monitor retains its original color, birghtness and vividness, I don't notice any degradation in image quality. According to the specs I read in the Manual it says: "Light Source: Long Life, 50000 hours (typ.)". So let's make a rough calculation, say I used this monitor an average of 5 hours per day in the last 10.5 years, that means I still have left 30840 hours of lifetime, so if I keep using this monitor at this same rate then this monitor will last 17 more years, until 2029!!.

Hi bendix, as I mentioned earlier I received the VP230mb as a gift and it was purchased brand new for $3500 back in December 2001. I'm surprised about that pricetag you found ($6235), the manufaturer's price is always higher, but that is a huge ripoff.

Here is some information on LED's and LCD's http://en.wikipedia.org/wiki/Light-emitting_diode http://en.wikipedia.org/wiki/Liquid_crystal_display Maybe this will help understand the two and the difference's between the two.

[jagabo]

The only 'real' LED monitors are OLED based and VERY expensive at the moment.

I guess this a stretch, and not many people use them as monitors, but Sony Jumbotrons are true LED displays.

[Backpain]

OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity.

[usually_quiet]

Present OLED screens wear out too fast and fade unevenly. Blue dims most quickly.

I remember seeing that Sony showed off a CLED (Crystal LED) prototype TV at CES in January. If the technology proves feasible for the consumer TV/monitor market someday, it would provide screens with a longer lifespan than OLED, but that day is still a long way off, if it ever comes.

Pioneer has a line of plasma monitors north of $7000. What makes them so expensive, and does plasma technology rival LED IPS?

Those are really large TVs without tuners. They are supposed to be used with an external tuner/receiver or other A/V source. The PDP-5030HD is a 50" TV from 2001, when a flat screen TV of any description was rather expensive, and a large one cost a fortune. The PRO-141FD is one of Pioneer's famous KUROs with a 60" screen. The entire KURO product line proved unprofitable and production ended a few years back. They might be used for digital signage or in a commercial setting.

Yes, the older ones were CRT based. Newer ones are LED based.

If you want a 70" TV for a computer monitor and have the cash go for it.

Yes, while the KURO line of plasmas were discontinued, they were replaced by a KURO LED line with the help of Sharp, who now owns a big chunk of Pioneer. I guess you don't remember that flat screen TVs in general were more expensive 3 years back, when the last KURO Plasma was made.

If you are referring to the monitor that I linked to, it is made specifically for commercial use and digital signage, and that is why it retails for more.

LCD monitors are the longest-lasting of all display technologies, built to last at least 20 years. CRTs last about 10 before the focus is lost, Plasmas last a bit less because of image burn-in and OLEDs don't last more than 2-3 years before the blue diodes noticeably degrades before the others.

[Cornucopia]

The LC portion may last very long, but the backlight often doesn't. Many CCFL backlights go out after 5 years, though this has improved recently. LED backlights should last >10 years. Many Red, Orange, Yellow & Green LEDs last MUCH longer (25-40 years). Blue Diodes haven't been around long enough to have lifetime testing. OLED degrades differently than standard LED (because they're "organic").

Of course, this doesn't count things like power supplies. Many PS's are made so cheaply these days that they are the first things to go (~3-4 years).

I never changed my PC's PSU, 11 years of almost continuous operation and still running!

70" is too small!! I want this one!!!

CRTs last about 10 before the focus is lost

Both my 1987 Sony Trinitron KV20HFR (25 years!) and 1995 Sony Trinitron KV27S15 (17 years!) CRT TV's are working like new!

[Mephesto]

That's because you probably got accustomed to the blur, much like I got accustomed to my piece of shit LCD monitor. Compare it to a brand new, unused CRT monitor and see if it still rings crisp to you.
