Daniel is nearly blind and he recently had to get a new computer monitor. He connected it via VGA, but he's getting strange color bars across the picture. He switched to HDMI and gets no signal. Leo suggests updating the video drivers. If he has trouble installing the drivers, reboot in safe mode and install them. Here's also how to force a driver install.
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.
Susan's windows screen also goes jumping around. Leo says that it could be several things. The first thing to fail in a laptop is the thin ribbon cable that runs from the computer section to the folding screen. It's a common problem. It could also be the video drivers or some other software issue. Try booting into Safe Mode and see if you can replicate the issue. If there's no problem, it's a driver issue. Remove the driver and reboot. Windows will reinstall the driver, and it should fix the problem. If it doesn't, you can get a USB with Linux (Ubuntu.org) and then reboot it.
Quincy likes using MINT Linux on his old Dell Latitude laptop because it looks a lot like Windows. But the video has been glitching. Leo says that Mint may have chosen the wrong driver when he installed it. Linux uses video drivers made mostly by enthusiasts, and relying on the motherboard graphics is the easiest to get drivers for. But he may want to check the video card manufacturer to see if they have a Linux driver available. Try googling the model laptop with Linux and see what drivers pop up, and who has solved that issue.
Paul was forced to update to Windows 10 2004, he is having issues playing games. Leo says 2004 has been messing up a lot of installs and he suspects it likely messed up the video card driver. Try rebooting into safe mode and see if the game will run. If you can see the video, then it's definitely the video driver. Leo also recommends manually changing the drivers itself. You can go to your video card manufacturer website and download and install the latest driver for that card. There's also a reference driver, and a Microsoft certified driver. Try all three.
Navy wants to register a domain. What's a good site to do that? Leo says that (TWiT Sponsor) Hover is a good place. He has most of his domains registered there. One thing though, the pricing of domains has changed. They used to be about $10 a year, by the creators of domain extensions have started to charge more for their custom domains. Another good option is Google Domains. He can get a domain for about $12 a year. The chatroom says that Cloudflare has cost pricing for registration/renewal.
Jose has a Dell 2 in 1 laptop and the screen goes intermittently black. Leo says that it's a common issue with 2 in 1s because the ribbon cable gets "pinched" as it gets bent back and forth. Eventually, it frays and breaks. The good news is, that it's an easy fix to replace it. Before you do that though, update your video drivers. That could fix it as the drivers can get corrupted. But if the problem persists, it's a hardware issue.
Daryl is running Windows 8.1, but after a so-called critical update, he gets a black screen. Leo says that sometimes an update can break something, and it sounds like it may be an incompatible video driver. First thing to do is to boot into Safe Mode. Then, if his screen comes up, that indicates a driver issue. Daryl should go to the video card manufacturer's website and download the latest video driver.
John built a Windows 10 machine, upgrading from Windows 7. But now it's slowing down while playing videos and he has to do a hard reboot to restart it. Leo says there's a setting in the video driver that is for "hardware acceleration." If it's on, he should turn it off. If it's off, he should turn it on. That may fix it. He can right click on the desktop, then click through the following: personalize, display, change display settings, advanced settings, graphics property box, troubleshooting, change settings, display adapter troubleshooter for hardware acceleration.
Larry is having trouble with his NVidia video card which keeps crashing, especially when watching HD video. The screen will go black and he'll get awful sounding audio. Leo says that's a sign of a bad or corrupted driver that will write improperly to the memory buffers. The only thing that can do that is Windows itself or a driver. Reinstalling the driver could solve the problem.
