Plasma leaks out :nope:.

One thing I did notice is that if I do a search for TFT monitors I get nothing only if I do a search for LCD, I even went to the LG site & TFT is not mentioned in any specs, not even in FAQ section, how do you know if it's TFT, is that the screens with the squishy film on it?:-? Thanks, as I said I really don't know anything about them.:88)

This might help you Reece. :up:

http://www.wisegeek.com/what-is-a-tft-monitor.htm

A typical active TFT panel capable of resolutions of just 1024x768 is made up of nearly 2.5 million transistors (commonly known as small 3 legged lumps of silicon found in TV's and most other electronics) eccept in this case, the transistors are etched onto glass, to microscopic precision hence the name "Thin Film Transistor". A normal LCD basicaly has two layers of glass, one with rows, one with columns, this makes up a grid that can be referenced to control each pixel. The control is done with an IC (integrated circuit or silicon chip) on the LCD's circuit board/s. TFT's tend to be quicker ( response time) and nicer to look at in general. An old quote from somewhere I don't remember...

Basically, LCD is now the standard and has shortened it's response (refresh) time to be competitive with CRT's.

That's about as geeky as I get at this hour!!!

Actually Peto, I am a retired Electrical mechanic & completed courses in industrial electronics, and studied digital electronics, but that was way back in the late 70's, I have been retired for over 20 years now!:dead: I know a lot about CRT's but LCD's are relatively new & wouldn't know the difference by apearance between LCD & TFT LCD screens.:oops:
Interesting read about dead transistors though, has anyone had any & does it look obvious?:doh:
Thanks.

Nice monitor Jim, I think the response time is important for gaming, the one I was looking at (LG L1919S-SF) is 8ms, the more expensive ones are 5ms, is there really any notable difference, is this important for gaming?:-?

I just replaced my last CRT with a LG Flatron.

Most important thing for me was that I gained a LOT of space back in my little office corner :up:

IMO no...certainly not for a game as sedentary as a sub sim, but I don't profess to be an expert :lol:

Point taken Reece :up:! When Flat panels 1st started to roll out, Dead Pixels were a big issue. The company I worked for had set tolerances of how many dead pixels were considered normal (I think 8 was the number). That was actually a better policy than most Big Box manufactures at the time. And, Yes--they were visible if you looked hard enough for them.

In the last year or so, I've sold quite a few LCD monitors. I have had Zero complaints about dead pixels--regardless of the monitor manufacturer. No one has asked for a TFT display and--frankly--I hadn't thought about the term for a long time until you brought it up here. And if I don't use a computer term, I forget it quickly because there are so many new ones I have to learn to keep up :shifty:.

In a nutshell--the TFT's were faster. LCD's these days are also fast--fast enough for my gaming customers who are typically the most demanding. The only person I know that won't make the change is an engineer who does some major AutoCad work--and he's probably better off with his CRT (a Very high end one).

Seriously--I believe a LCD will meet the needs of 99% plus of computer users out there today. The technology has matured and the main issues of dead pixels and response times have been over-come.

If you'd still like more info, I'm sure I can dig some up when I'm at work. But that won't be until Monday or Tuesday.

Cheers!!!

What is your old LG CRT? Is it a 995E? If so, I can get you a buyer. Also, I wouldn't trade that monitor in for an LCD if it is. The 995E probably has one of the best color profiles of any monitor ever made, which makes it an ideal gaming monitor. You will not get that much richness on an LCD ever. Maybe when AMOLED is more widespread, you will have a better chance, but today you don't.

By the way, TFT is a way of stating Active Matrix. Almost all LCD monitors will be TFT these days, since the alternative is very slow and ugly looking. The point being, to get an 8 ms Rise or Fall time in a pixel is not possible with a Passive Matrix system.

What you should be more concerned about is it's color output. To put it into simple terms, faster LCD monitors cheat by only using 256,000 true colors, and they mix and match that and then claim it is a 16 Million color monitor when in fact it is only 256,000. It slows your rise and fall time down to make the full 24 bit true color, so this is not desirable when gaming, and to make matters worse, no one will tell you in their spec if it is a 6 bit or 8 bit per pixel monitor (Since your an old CRT person and undestand this terminology - think three together for RGB for 18 bit or 24 bit respectively)! :down: You sort of have to figure it out from the clues given. Marketing people drive me nuts sometimes.

I have a single dead pixel on my LCD screen, and while it is very annoying at times, for the most part, it is of little consequence. However, I will admit that having this bright yellow dot on the screen during dark sequences in games is annoying. That being said, I do not intend to go back to a CRT - ever. The space savings far outweigh any inconvenience caused by dead pixels.

The WosMan 11-24-07 04:52 PM

I have a 19" ViewSonic VX922 and I will never go back to a CRT again. I think they are easier on the eyes too, especially if you dim the brightness on them to about 50% or so. At my office everyone has dual LCDs and it is great. Being able to see the refresh rate on the CRTs I wanted to throw up whenever someone would ask me for help and I would go to their desk and their monitor was on 60hz and I could see that damn flickering. Now that everyone has a LCD it is beautiful.

Reece 11-24-07 06:05 PM

Thanks for the explanation Peto, I must assume that a dead pixel is not really noticable although JSLTIGER just pointed out:

I will just have to take a close look at a few I think to see if it really is noticable, JSLTIGER's problem could be dead video ram.:huh:
Subman1, my monitor is not a true flat screen, it is the cheaper 900B.

This is a little worrying, I will have to do more research on a particular monitor, need to find some reviews relating to gaming aspect!:yep:
Thanks The WosMan, the ViewSonic VX922 is quite popular & relatively cheap, ViewSonic CRT monitors back in my days were very poor, seems they got their act together.;)

SUBMAN1 11-24-07 08:33 PM

Hey Reece - it is much more annoying when your stuck pixel is GREEN! :D Buy from Fry's - they will take back a monitor without question. Newegg has a 6 pixel policy before you can return it, and TRUST ME when I say - 1 dead pixel sucks. Maybe not when it's yellow, but i have seen GREEN stuck pixels (Green seems to be the standard of stuck pixels. I have not seen really any red or blue, but I tell you green is a really bad color to get stuck pixel on) and they stand out like a SORE THUMB!

The moral of the story is, buy from a place that accepts returns without question from.

-S

PS. Too bad it wasn't a 995E - I probably would have picked that up from you myself. I do have one 995 E in this house, and people can't believe the difference between the picture quality of the 995E, and say a Sony tube (There are six monitors in this room I am typing in - 3 LCD and 3 CRT - one LCD is even an expensive Samsung, and one of the CRT's is a 20" Sony Tube). The 995E stands heads above any of them. The Samsung LCD is not half bad though, but it can't hold a candle to the 995E - Ever! I wish you could see the difference. CRT will remain the superior picture at the expense of Size and Power consumtion however. I guess if you want to get technical, most people probably bought a cheap CRT, so a decent LCD may actually end up looking better in that case.
