Does dot pitch determine video resolution?
No, we hear that too, but image resolution has nothing to do with the monitor’s .26 or .28 mm dot pitch. Dot Pitch is the spacing of the monitors red, green, blue phosphor dots on the physical screen. Smaller dot pitch is better, it can improve the sharpness of what you see, but it is fixed for the monitor and is not related to the specific image at all, nor to the specific screen resolution either. The dot pitch never varies for the one monitor, regardless of screen resolution setting. It’s more like a filter that we view the image through, which purifies the image we see. The image pixels are instead created in the video board’s memory, to match a previously specified screen size like 800×600. The video board has enough memory bytes to store the three Red, Green, and Blue color values for every individual pixel in the 800×600 image. 800x600x3 = 1.44 million bytes, which is why 2 meg video boards were popular. But 1024x768x3 is 2.36 million bytes, which is why 2 meg boards can’t do 24
