The truth is that ZoomText doesn’t really care – it magnifies whatever is on the screen.
Most ZoomText users want a larger monitor so they don’t have to scroll around as much in the magnified view. But let’s talk about that before you decide that bigger is better. To compare apples with apples, picture two monitors set to the same screen resolution side-by-side – one is a 17-inch screen and one is 21-inch screen. You have solitaire on the screen without ZoomText running. Are you seeing more on the 21-inch screen than on the 17-inch screen? No, you’re seeing the exact same thing. But of course everything will be bigger on the larger screen so you may be able to sit back more. Now picture ZoomText magnifying the screen at 2X on both monitors. On each screen, you are seeing one-quarter of the screen at a time. Again, you will have the exact same view on both screens, but things such as the cards will be larger on the larger screen.
Aha! You think, now I can reduce the magnification level on the larger screen so I don’t have to scroll around as much. Well, maybe. If you are a 5X user, the difference in screen size may or may not be great enough to allow you to drop down to 4X. But for a 2X user, you’ll likely be able to go down to 1.75 or 1.5X.
But what if your new larger screen works best at higher resolution than your old screen? Higher resolution means smaller text, so you might not be able to reduce screen magnification as much as you anticipated. But if you can sit back a little more and reduce the magnification a bit, this is an improvement in the right direction. Now let’s consider ergonomics. Sitting back is good but are you someone who will need to sit very close to the screen no matter what size? Sitting close to a large screen makes it more likely that you’ll need to move your head up, down, left and right to see each part of the screen. Trust me, your neck will complain about this, so you might not want to go overboard on screen size.
Your particular vision impairment will also play a role in selecting screen size. For me, I have poor central vision, so I’ve chosen a 22-inch wide-screen LCD monitor and love it. I sit about one foot away and don’t have to move my head around in order to read text on the screen, and I can adjust the height of the monitor for more comfortable viewing. I’ve also had customers purchase much larger screens and be extremely happy with their decision. Perhaps I don’t know what I’m missing. One thing is for sure – replace that old 17-inch CRT with a space-saving, lighter LCD and you’ll be much happier!
