Why Are Touch Screen Monitors so Much More Vivid?


Leo, I’m looking for a monitor, 22 inches. I’ve been in several stores and no one can tell me why a touchscreen monitor is so much more vivid and bright, and the images just jump out at you compared to say, an LED or LCD monitor. What a difference! I’m running Windows 7 and I’m thinking this is what I’m looking for. It seems that these monitors are used on an all-in-one PC. Are they available separately? I don’t have any intentions to use the touchscreen but the colors and the display are unbelievable! What’s the difference? What do these monitors have that the others do not? And also, are these monitors even compatible with Windows 7?

To be honest, I don’t know. I can and I will speculate a little – but I do want to talk about touchscreens, specifically with respect to compatibility and hardware requirements.

Realize that most of the touch screens are in fact typically just LCD monitors with additional touch hardware.

Why Does My Monitor Go Dark for a Few Seconds?

Leo, I’ve got an HP Pavilion H8 1017, which I love dearly. I’m on a Windows 7 operating system and it’s standalone. I use it mostly for graphic work: Photoshop, video editing, and the like. Lately, my screen goes black for about 10 seconds whenever I stop what I’m doing and open another program. I’m afraid that this may be a prelude to the blue screen of death. I do disk cleans and defrags regularly. I have McAfee protection and AOL computer checkup and backup. Please help! I don’t want my HP to become the recently departed.

A screen going dark isn’t likely to be a computer problem; it’s probably a monitor problem. Your HP is a desktop model, which means you have a separate monitor.

I have a similar problem with my machine. After doing some research, I have a couple of ideas.

Let’s start by getting some of the obvious things out of the way.

Can I Add More than One External Monitor to My Machine?

I own an Acer Aspire 5750 with an Intel HD graphics 3000. I’m currently using it with one external monitor and the laptop monitor. Can I add a second external monitor and have all three monitors working at the same time? The operating system is Windows 7 Home Premium, 64-bit with 8 GB of memory. I’ve done some searching without success. I’ve sent a request to Acer about a month ago. So far, no answer from them.

I can think of several different ways to add a second external monitor. Not all of them will work on your laptop – that depends on your machine’s capabilities – but some will.

Let’s look at your options.

What’s this obscure message on my monitor and why can’t I make it go away?

Hi, Leo. A small, 50 mm by 5 mm blue “flag” with the legend (a number of unintelligible characters) has recently appeared on my screen. It’s permanently on the top; even the pointer disappears underneath it. At the same time, my monitor screen has begun changing colors even when the PC is switched off (although this stops once have it booted up). It does not seem to affect the operating of the computer or to do anything but sit there, which is annoying. I’m using a Packard Bell PC with Windows XP Pro. Help to remove this would be much appreciated.

Most people don’t realize that everything that appears on your screen is not always put there by your computer. Because the mouse pointer disappears when you move it beneath the flag, the monitor itself probably put what you’re seeing there.

I, too, have encountered the occasional odd message on my monitor.

Why Doesn’t My External Monitor Work?

I’ve connected my Optiquest monitor to my HP PC but it won’t restart. I get an RGB “no input” message. What can I do?

This is actually an example question. I get a number of questions like this from time to time. The scenario is this: you have something like a laptop whose screen has failed. In other words, you can’t see what’s on your computer. One of the very common approaches to try and work around that until it gets fixed or replaced is to connect to an external monitor. The problem is that the external monitor doesn’t show anything.

There are a couple of additional steps that might be necessary, beyond just plugging in the monitor.
