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.
Owen wants to know how he can protect his pro-level cameras. Leo says you can 1) never use the branded straps that come with the camera 2) buy a cheap leather case and wear it around your neck 3) place electrical tape on the white logos to make it harder to see what brand your camera is.
John has a Radeon graphics card and he wants to know if he can use three monitors running it? Leo says that most modern video cards can handle four or more, so it's not too much a stretch to do three. Look it up in your manual and just try it in the end.
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.
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.
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.
Dave's wife got a "blue screen," and he thought the monitor was the culprit. Leo says the simple and cheapest solution is to swap out the monitor cable first. If the issue persists, he should try updating the drivers. He can create a bootable thumb drive that will allow him to get into the computer without running the hard drive. He can also do it from a CD. His recovery disc will do this as well. Then if it's a driver, booting to a separate OS would tell him a lot. If it's still blue, then he'll know it's a hardware issue.
Jack wants to build his first computer and he has a budget of about $800. He needs a good gaming quality video card. Leo says that learning how a computer works is a great reason to build one. Leo recommends going to PC Perspectives and check out their hardware leaderboard. Leo says that the AMD XFX video card is the best in that price range.
Dan has a 24" screen because he's into music recording. Should he buy a new video card? Leo says not for that screen. At 1920x1080, any video card is going to handle it. Leo says that the processor and RAM are more important for editing music than a video card. But it he requires a set manufacturer like Nvidia, a low end card will work just fine.
Ken has a problem with his monitor. All his icons have turned to negative. He tried to change the cable, and he even tried another monitor. Leo says it may be that his settings were changed. Ken should go into accessibility and see if it's set for high contrast mode. But when he unplugs it and plugs it back in, it goes back to normal. Leo says that's odd. Leo says to update the drivers on the video card. If it rights itself when he tries again, that points to a hardware issue and Ken should try replacing the video card.
