Why did the touch screen on my point of sale system go out?

Episode 1415

Kevin from Palm Desert, CA
POS

Kevin has a point of sale touch screen system and it blacked out right in the middle of sale and didn't come back. What can he do? Leo says that when a screen goes out, it could sometimes be the backlight. If he looks at an angle, he may see a very dim screen. But if it's totally black, that means that the screen completely died. Or it may be a bad cable. Leo suggestions changing out the cable to start. If it's proprietary hardware and software, then it's not going to be user repairable.

How do I know if I have the right glasses for the eclipse?

Episode 1415

Clarence from Virginia
Eclipse

Clarence says that if you grab the wrong pair of welding glasses, it'll be just like having a huge flash going off in your eyes. So he advises taking a quick glance at the sun with the glasses on, then look away. If it looks like a camera flash, then you have the wrong glasses. Leo agrees. The damage the sun does to your eyesight will never heal. It's permanent and it's not worth risking for two minutes.

Can I stack welders lenses to view the eclipse safely?

Episode 1415

Ben from California
Welders Glass

Ben wants to enjoy the total eclipse but all the glasses are sold out. So he's looking at welding glasses, but can't find 14 grade lenses. Can he stack two 8 grade lenses together? Leo says he doesn't think that they are additive and it won't work that way. It's certainly not worth taking the risk. The best place to find out what to wear is the NASA Eclipse Website.

What's the best monitor for my laptop?

Episode 1412

Cathy from Laguna Nigel, CA
Dell 27" Monitor

Cathy is looking for a monitor that she can use with her laptop when she's at home. Leo says that any modern laptop will have an HDMI port and that will connect to an external monitor. In fact, some can support up to three monitors!

What size should she get? Leo says to go with the Dell 27". It's very affordable and the color quality is really good. ASUS also makes monitors, and they are very wide for gaming. It would be great for what Cathy needs as well.
