Jim wants to know if he can use his old Atari gaming console with his new TV. Leo says there are ways to do it, but he will need a "composite" adapter to do it. Most modern TVs don't have composite inputs anymore. Those are the red, white, and yellow connectors. You may also need an antenna adapter. Jim will need to get a composite to a digital connector which may actually cost more than that old Atari game is worth. But he can get one from Monoprice for under $20. Don't expect great video though.
Grant wants to only hear his headphone sound in mono because he's only got good hearing in one ear. Leo says that PopOS has only Surround and Stereo. But there's bound to be a mono sound driver online somewhere. Probably the easiest way would be to get a hardware option. People used to be able to get one at RadioShack. But sadly, that's in the past. Doctor Mom says that he can make headphones mono with an adapter from Monoprice. Here's how - https://www.cnet.com/news/making-headphones-mono/.
Don has some Kodak photo CDs that he'd like to retrieve images from. He heard that Contenta is a good option, but it's pricey and Leo says he shouldn't have to spend any money on it. Unfortunately, photo CDs from the 90s were stored by Kodak in a proprietary PCD format. Leo recommends IrfanView since it can read PCD files. Don should be able to see them, open the files in IrfanView, and get them off into a more palpable format like JPG. But if he can't see them, TedFelix.com says PCD to JPG converter can do it as well.
John traveled to the UK and he got an inverter that nearly bricked his laptop. Leo says that most of the time laptops don't need a transformer because they're built for a world market. Just a plug converter is needed, or a travel adapter. They're only about $10, even at the airport. He should always look in the fine print of the device. It'll tell him the voltage it can handle.
Tom has a picture with the format .KQP from a Konica camera. How can he convert that? Leo says there's a great website for this at OpenWith.org. He can search by extension and get help on how to open it. It recommends XNView for this particular file, and they also have a converter. He should check out XnView.com.
Gary has a 3rd Generation Apple TV, but he doesn't have an HDTV with an HDMI connection. Leo says that Gary can get an HDMI to component adapter. Leo advises checking MonoPrice.com.
There's a converter from Gefen, and the KanexPro. It's not cheap, and he will lose some quality. That's why Leo says it might be time to get a new HDTV. A Vizio TV would be affordable and has HDMI.
Nick is a church media guy and his church bought several TVs that they'd like to double as computer monitors. They don't have any VGA inputs to connect to the computers, though.
Leo says that the TVs probably have HDMI connections, and he would need a VGA to HDMI converter which will cost about $30 at MonoPrice.
Ken was streaming video on an older laptop linked to his TV, and the TV gave up the ghost. His new TV has no VGA port. Is there a USB to HDMI converter? Leo says yes, it's an analog converter, but it works. The quality won't be as good and USB isn't all that fast for super high resolution. How can it do that if it's bypassing the video card? Leo says it's done with onboard software.
Paul would like to connect his old laptop to his HDTV, but he doesn't have a VGA input on his TV. Paul only has a VGA output on his laptop, though. Leo says ideally, he'd want to use HDMI. Many modern laptops can use DLNA or Wi-Fi Direct that plays video over the air. Apple calls their version of this "Airplay". Paul's laptop probably doesn't support it, though.
