Watch John from Covina Comments

John wants to show video on two separate screens using an HDMI splitter, but it won't work. Leo says HDMI splitters are frustrating. Leo says that they often don't work and when they do, they likely only work with one screen, rendering it pointless. Leo suspects his problem is due to copy protection called HDCP, and if it's not HDCP compliant, it won't work.

An A/V receiver with two outputs may be a better option, as would powered HDMI splitters.

Scott Wilkinson says that if the displays have different resolutions, it's likely the information is confusing the splitter, thereby it can't work. It's always best to have the same displays when splitting. Jeff at the Brickhouse Studios says he uses a MonoPrice Matrix splitter. It works great no matter what the resolution is, and it costs about $160 from Monoprice.

Watch John from Poconos, PA Comments

John wants to know if the software available at the Internet Archive is legal to download. Leo says that the Internet Archive is a very interesting project. A record of life in the 20th century. It saves websites, audio, video, and even computer software. It's fantastic. But it may not be legal to download software from it. Since it's archival, Leo says it's probably safe to enjoy since the industry basically ignores it. Sooner or later, it'll have to be addressed by both parties, though.

Watch Ricky from Albequerque, NM Comments

Ricky took Leo's advice and bought a pair of LCD HDTVs. He thought they were too bright, so he returned them and got a Panasonic plasma. He was concerned because he lives at an altitude of 5,000 feet, but Panasonic rates it at 7200 feet, so Leo says that Ricky is OK. LG's plasma's are rated at 9,000 feet. Ricky says he loves the blacks and colors. But his issue is that after 100 hours the network logo in the corner of the screen has some ghosting and remains on the screen. Leo says it'll fade over time.

Leo says that burn in is a potential issue with Plasmas, but it's improved over time and the screen dims and the bug will fade. Leo also recommends having the plasma calibrated. It will give him true color that really makes a difference. Spears and Munsel make a really good calibrator.

Ricky also sees a kind of rainbow effect during motion. Leo says that action and motion is often an issue with both LCD and plasma, which is why they have higher hertz modes. But Leo says he's never really seen that issue and suggests that Ricky may be looking "too hard" for problems.

Watch Sterling from Nina, WI Comments

Sterling bought a new Acer Aspire M5 laptop that has Windows 8.1 and UEFI, but he can't install Ubuntu to dual boot it. Leo says that if he goes into the settings for the UEFI firmware, he can set it up. But it's not trivial, and it's not supposed to be. The BIOS can be modified to reinfect a computer, so UEFI was designed to combat that. It also causes dual boot computers to not work in that configuration. Leo was able to do it by disabling secure boot.

The chatroom also says to change it back to "Legacy." He can also try booting from a USB key. If that doesn't work, there could be driver incompatibility. Leo advises searching the net for it. The chatroom says that some Linux distributions are UEFI certified. Here's a technote that may help.

Watch Dave from Binghamton, NY Comments

Dave has started his own radio station online via Radionomy. He has a TuneIn station and is trying to create an iPhone app, but he doesn't have a Mac new enough to make use of the Apple Developer kit. Leo says that a 2007 version Mac will work, and he can use XCode if he doesn't want to pay for it. The $99 Developer Program fee gives him access to the Software Developer Kit.

What does Leo think about services that offer to create an app and he would pay to keep it up? Leo says that's not a bad idea since a radio app is pretty simple. Leo suggests looking at what other people use to create apps and ask them what they did. A radio app is pretty standard though

Watch Edward from Northridge, CA Comments

Edward has been trying to learn more about HTPCs (home theater PCs). He wants to make an old PC into a DVR. Leo says that copy protection is often an issue with this, and cable boxes are encrypted to prevent people from using their signal that aren't paying. A computer can descramble it with a cable card, but cable companies aren't that helpful with using them. They have to give you one by law, but they don't like it. The cable company pretends they don't know anything about it, even though it's been the law since 1993.

All too often, if your cable company has a store front, you'll have better luck going there than calling to get them to help. Then you have to be sure your hardware supports it, your capture card supports it, and your OS supports it. That's why Leo recommends just getting a TIVO.

Watch Luke from Adelaide, AUS Comments

Luke's school is ending the laptop use program, but they're letting students bring their own. Leo says that's sad, but it is expensive to implement. It's vital for digital literacy, so it's a great idea to for him to have his own. Unfortunately, not everyone can afford a computer, which is why it's important to teach it in the schools. It would also be an IT nightmare with a variety of different laptops and security configurations. Leo says it's really necessary, though.

Watch Harry from Long Beach, CA Comments

Harry wants to know Leo's thoughts on parental controls on the Internet. Does he know about TimeBoss by Nice Kit? Leo says that TimeBoss is a great piece of software but he's stunned it's still around. It basically allows kids to earn time. But does it really help kids manage their time? As adults, we have to understand our kids are growing up in a different culture than we did. The internet is how they socialize, and how they learn. Minecraft is light years better than getting hooked on Candy Crush.

It's possible to get around software, which is why Leo recommends OpenDNS. It can control the Internet from a place that kids can't get around. He'll also have to balance it with the notion that if he takes it away, they'll only want it more. It's better to make it an empowering opportunity. Talk about limits and concerns, and make sure he knows what they're doing. Give them limits.
