Chip Shortage Making High End Tech Scarce

Computer Chip

Episode 1782

Due partly to the Covid pandemic and partly due to a recent fire at a factory in Japan, there is a serious chip shortage now, causing car manufacturers to stop production and prices to rise on high-end tech like video cards and other devices. Coupled with how high the price is now on bitcoin that is prompting scalpers to buy up video cards for bitcoin mining, it's making it really hard for the rest of us to get Playstation 5s, video cards, and other devices. 

What Is CUDA & Can I Use It With Linux?

CUDA

Episode 1778

Franklin from Maui, HI

Franklin wants to know what CUDA is in a video card and can he use it with Linux? Leo says that CUDA is a performance codec that will help higher resolution video perform at various frame rates and resolutions. The key is to make sure he's using the proprietary NVIDIA drivers for the best results. If he's using Linux, though, it's possible he won't get CUDA support, especially with Linux drivers. He could also make sure that he has OpenCL drivers as well. 

Crypto Currency Continues to Rise in Value

Bitcoin

Episode 1773

CryptoCurrency continues to rise in value as more people seek to acquire it and use it to pay for goods and services. Currently, BitCoin's value is over $55,000 as of 2/21. Leo says that bitcoin miners will only be able to generate 21 million bitcoin before it comes to an end as far as BitCoin is concerned. And the closer users get to that amount, the harder it will be to mine bitcoin, which is achieved by solving complicated mathematical problems. But that isn't stopping bitcoin miners from trying.

How Can I Add a Type-C Port to My Computer and Drive 3 Monitors?

Thunderbolt 3

Episode 1701

Jake from Denver, CO

Jake has transitioned to a home office for his work. He has a three monitor setup for his laptop and docking station. He has another older computer that can only drive two of the monitors because it doesn't use USB-C. So he added a USB-C card. Still two monitors only. Leo says that Jake's video card is probably too old to drive all three video monitors. Are there any discreet graphics cards that can handle USB-C? Type-C can be USB 3.1 or Thunderbolt 3. Looks the same. So it can be confusing. 

How can I fix a display issue in Linux?

Linux

Episode 1636

Stan from St. Louis, MO

Stan is having a computer display issue. He has issues when he plays video.  But when he uses Linux remotely, he has no issue. But when he's on Linux directly, he has an issue. Leo suspects that there's an issue with the video card. Maybe an incompatible video driver. You could remove the driver, and reinstall it. Or, get an inexpensive video card and see if it fixes the problem. Leo says that using a different flavor of Linux, like PopOS could also solve it.

Can my Computer Handle a New Video Card?

RayTracing

Episode 1575

Larry from SF, California

Larry is a gamer and got a new video card that supports RayTracing. He put it in his computer but it's lagging terribly. On top of that, he's now getting "green sparkles" everywhere. Is his machine too old? Leo says it shouldn't be too old at all, it's likely just a bad card. Green artifacts are usually an indication of a bad video card, so Larry should send it back for a refund or replacement. The GTX 1070 is better matched to his computer anyway.

Do I need another video card for 4K?

Video card

Episode 1405

Roy from Pasadena, CA

Roy has a high resolution 4K monitor, but his friends say if he adds a second video card, it could give him better resolution. Is that true? Leo says no. A newer one with more RAM could help, but if he's driving the monitor at its full resolution, then it's not going to get any better than that. A second video card would give him the ability to add more monitors, though.

Is my laptop dead?

Episode 1231

Mike from Riverside, CA

Mike has an HP Pavilion G Series laptop and the screen has gone black. Is the screen dead? Leo says that it could be. In laptops, it's often a frayed ribbon connector that has obstructed the video signal. Mike should try hooking it up to an external monitor to see if he can see it. If he can, then he'll know the computer is OK but the screen has either died or the ribbon cable has broken. But if he can't see anything with the external monitor, then it's probably the video card that has died or the motherboard has failed.
