Question: My TV doesn’t look as good at home as it did in the store. Should I take it back?

Answer: No, your TV just needs to be adjusted to work better with your home lighting. Right now, it’s set to look good in store lighting. As a quick fix, use the suggested settings for your TV model from TweakTV and then make small adjustments from there to get the look you’re after.

Spot a fake charger

Q: I lost the charger for my phone and I see a few online that are really dirt cheap. Is there a catch?

A: Yes, knockoff chargers do exist but they aren’t safe. Gadgets have caught on fire by using them. So, spend a little more and buy from the phone manufacturer or a reputable source.

Tidy Facebook history

Q: I have a new girlfriend and she’s all over my Facebook account. Is there an easy way to go back and make sure there’s nothing embarrassing in my Facebook posts?

A: That’s what the Activity Log is for. Log in to Facebook, and in the upper-right corner click the downward arrow, and then choose Activity Log. You can choose an activity to review, such as Past Posts, Photos, Likes and more on the left. Anything you don’t want to keep, you can remove or hide from your timeline.

Are your neighbors stealing your Internet?

Q: I heard a caller on your national radio show and I also think my neighbor might be stealing my Internet. Can you tell me again how I can tell for sure?

A: Well, hopefully you have your network encrypted, which will keep out most freeloaders. Still, if you want to double-check, grab a program like Wireless Network Watcher that shows you every gadget connected to the network. Check it occasionally and make sure you’re the only one connected.

Clean gadget screen

Q: My smartphone screen needs a serious cleaning, but I don’t want to damage it. Any suggestions?

A: A microfiber cloth is the best option, and you probably have one in your phone starter kit. If that’s not quite doing it, dampen it with some distilled water — some people use a 1-to-1 mixture of water and white vinegar or rubbing alcohol — and try again. As a rule, don’t use a glass cleaner with ammonia on gadget screens because it can cause damage.

TribLIVE commenting policy

You are solely responsible for your comments and by using TribLive.com you agree to our Terms of Service.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
