If it's artwork, Graphics Interchange Formats are better. A .gif file uses a maximum of 256 colors. The fewer the colors, the smaller the file. A .jpg file can have millions of colors. CRT monitors look brighter because they create images directly with light, whereas an LCD must shine light through a layer of liquid crystals that deflect the rays to make different colors.
Flat panels consume a lot less energy and a lot less space.
But they cost a whole lot more. Call me old-fashioned, but I prefer a CRT on my desktop. The Sneaker Sleuth is on the case. Net's author, GCN Lab manager Michael Cheek, will answer questions about computer problems. If your question appears, you'll receive a GCN T-shirt.
