Dual Link DVI

Episode 1822

Gary from Cheektowaga, NY

Gary has a computer with a gaming video card to connect multiple monitors. Can he use three 4K monitors or a QuadHD monitor? Leo says it doesn't matter. Modern video cards can display 4k with no problems, even in HDMI. You can also add a monitor through the display port. What is dual-link DVI? Leo says that was something they came up with for the Display port to drive higher resolution monitors.  But HDMI can handle 4K now, so that doesn't matter. 

Can I Just Swap Out My TV in My Home Theater?

Samsung QNED QN65Q

Episode 1815

Laura from Goldendale, WA

Laura has a 17x20 living room with a 10-year-old TV that she wants to replace. What size should she get? She's looking at the Samsung QLED QN65Q. Will her speakers be plug-in-play to support them? Leo says yes. Whatever sources they have in the receiver will be supported. She just wants to be sure to plug the HDMI cable into the port that says "ARC." That's the Audio Return Channel, and it'll keep the audio in sync. If the TV doesn't support ARC, then she needs to opt for the optical connection, and some TVs are dropping that. If that's the case, she may need a new AVR.

Mark from Oxnard, CA

Mark would like to connect up to four monitors on his laptop. Can he connect two by USB? Leo says that it will work. There are a lot of USB monitors out there. But there may be a limit that the video processor can push pixel-wise. So it depends on your video card. Look at your specs. And if you are using an external GPU, you'll need a driver to do that as well. But don't go above 1080p. That'll help. 

Why is My TV Flickering?

HDMI Troubleshooting

Episode 1793

Louie from Orange County, CA

Louie is having home theater issues when he switches from his TV to blue-ray and back. He's getting flickering. Leo says that there's an HDMI handshake that happens between your AV receiver and the television. So, Leo says it sounds like the handshake may be failing for some reason. It could be as easy as a bad cable. Probably the HDMI cable. The TV ports may also be slightly expanding when they get hot. So try a different HDMI port to be sure.

LG TV

Episode 1788

Joe from Marlborough, NJ

Joe would like to connect a pair of headphones to his LG TV. But when he does, the volume is very faint. Does he need some sort of amplifier? Leo says that most TVs get their audio from HDMI and the Audio Return Channel. If Joe has a home theater system or AV receiver, it's better to plug into that instead of the TV. What Leo thinks is maybe Joe needs to enable the setting in the TV menu. There are headphone amplifiers. Check out headphones.com for suggestions on which to get. There's plenty of options out there.

2020 New Mac Mini

Episode 1748

Will from Denver, CO

Will is ready to buy a new Mac Mini with the M1 Apple Silicon processor. He wants to use it for photography. What monitor should he get? Leo says to avoid the Apple XDR display. It's just too damn expensive. The Mac Mini supports Thunderbolt and HDMI, so it can drive many models. Dell makes some really nice monitors for 200-300, but their UltraSharp line would be similar to Will's old iMac. You can get a 27" Dell UltraSharp for $359. 

How can I turn on my Apple Cinema Display?

Apple's Cinema Display

Episode 1740

Paul from Delaware, OH

Paul was recently gifted an Apple Cinema Display. But it doesn't light up if he plugs it in. Leo says there's no on/off switch on that old ACD. You just have to plug it into a computer that has a display port to get it to turn on. You may need an adapter for Display Port to HDMI. 

Paul wants to also know what's the best streaming box. Leo says that Roku seems to be the most compatible, but some ISPs have deals with other boxes like Apple which can give it better programming or preferred traffic. So Apple TV may also be a good choice depending on your ISP. 

Why is my audio video signal dropping out on my TIVO?

Tivo Edge

Episode 1730

Bruce from Las Vegas, NV

Bruce is having issues with his TV that the audio gets out of sync and the video goes blank on his TIVO Edge. Leo says it's losing HDMI sync when you run it through the AV receiver. And it's likely the AV Receiver that's causing it since Bruce isn't having issues connecting through his Xbox or directly. Is there a setting he needs to look for in his AVR? Look in the settings for eliminating the sync handshake. That's what's dropping out. If you can make it always on, it would never have to lose the handshake. Leo also suspects a new HDMI cable may solve the problem.

What AV Recevier should I buy?

Episode 1714

Hans from Los Angeles, CA

Hans would like a good home theater receiver and turntable that can also work as his home theater. Leo is a fan of Denon. Onkyo and Marantz are also very good. They are very affordable and give you a lot of bang for your buck. Be mindful of how many inputs the AVR has, because it can double as an AV receiver. So count up your HDMI devices you have hooked up and it'll point you to which model to get. Leo, for instance, has seven devices he connects to his. Also make sure it can support 4K and HDR to future proof your system, as well as Dolby 7.1 Surround Sound.

Vince has a Sansui receiver from the 70s. Can he still use it with his home system and his Pioneer Elite Plasma TV? Leo says to check out ClassicReceivers.com. It really comes down to the output.
