Monitors oh where oh where are the old glass CRT'S?

OH you want to buy what?? A CRT? CRT oh you mean cathode ray tube? This is starting to sound like what happened to the old radio days of tube operated transceivers and yes even computers. The LCD panel and display is charging strong and the days of the old CRT are numbered. Here is an interesting article to read:




A monitor for photo editing

QMy wife is a photographer starting her own business. We’re planning on upgrading our computer monitor. We want one 24 inches or bigger. She uses Adobe CS2 for editing and has a Nikon D300. What do you recommend? We are looking for the clearest, sharpest monitor we can get for a reasonable price.

AOK, let’s put this into perspective. Your wife is using an $1,800 camera. Photoshop runs about $600. And your computer must be fairly powerful if it runs Photoshop.

My point? Now is not the time to skimp. Monitors designed for photo editing can run thousands of dollars. But they help you get the most out of your photographs.

For professional photographers, few things are as important as color accuracy. So, a quality monitor is worth the investment. It will help you get the most out of the money you’ve invested in other gear.

Traditionally, CRT monitors have been better for photo editing. (I’d like to see you try to fit a 24-inch CRT on a desktop!)

Manufacturers are doing away with CRT monitors, though. Fortunately, LCD panels are improving greatly. You can get an LCD monitor with the same quality image as a CRT. But you will pay for it.

There are several types of LCD panels. Skip TN (twisted nematic) panels. These are only capable of 6-bit color and 262,144 colors. In comparison, graphics cards can display 16.7 million colors. TN panels approximate the remaining colors.

S-IPS (super in-plane switching) is a better choice for photo editing. You’ll get 8-bit color and 16.7 million colors—without approximations. The color reproduction is also good.

On the down side, contrast could be improved. Response time is slow, but that is unmportant for photo editing.

S-PVA (super patterned vertical alignment) panels are also a good choice. You’ll get at least 8-bit color and 16.7 million colors. Response times are respectable, and the contrast is good.

Unfortunately, many manufacturers don’t list what type of LCD panel they use. In fact, manufacturers may use different types in different production batches of the same model.

If you look at high-end professional monitors, things are different. For example, Eizo and LaCie tout the panel type used in a particular monitor.

You may be able to find out what type of panel a particular model uses. That would probably take a bit of work.

But I can tell you what to consider. First, you want a monitor with a wide color gamut. Contrast ratios are important too. Brightness or luminance is also important.
