Bob is buying the new Apple MacPro. He was thinking of getting the XTR monitor, but he's not high on paying $1,000 for a stand. Leo says that the monitor is really a color reference monitor for professional colorists. It's a beautiful work of art, but it's also $6,000. So for 99.9% of us, it's not necessary. But if you're doing video, you're going to want a very color-accurate monitor. Apple will likely continue to sell the LG UltraFine 5K monitor as well. It's expensive as well, but not nearly as much as the Apple monitor.
Mike wants to know if he can use more than one monitor on his computer. Leo says that most modern-day computers do support multiple monitors and both Windows and macOS support it natively. But the computer has to have more than one display port or HDMI port to do it. Most do out of the box these days.
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.
Andy is thinking about getting into day trading. What does Leo think? Leo says to read FLASHBOYS. Trading is now an automated, high volume business, and trades are happening in milliseconds, often before anyone at the NYSE knows what's happening. That is the competition. And it's really easy to lose a shirt in day trading, as you get leveraged buying stock on margin.
He'll need a very powerful computer, but any laptop can do basic day trading. It's quite an investment. He'll also need software and a subscription to wall street's feed.
Charles is getting a new Mac Mini and wants to know what display to get for it. He currently has a 27" iMac. So what's most affordable for the same size? Leo says that Apple is pushing an LG 5K Ultra Fine display, but it's not cheap at $1,000. Prices have tumbled for monitors lately, and as such, there are plenty of options.
The monitor of Steve's Dell Inspiron has finally bit the dust. Leo says it's probably the cable that has gone bad or worked its way loose. He should try to change the monitor cable. If that doesn't fix it, he should swap out the monitor and see if that's it. Once he has eliminated the easy stuff, then he can look inside the computer. These days, the video card is wired into the motherboard, so that means either replacing the motherboard or getting a new computer. But he should try the easiest stuff first.
Andrew wants to be able to control several monitors separately by remote, but with regular IR remotes, everything he does will affect all of the TVs. Leo says ideally he'd like to be able to do this in software without the remote. Leo says it would be nice if those monitors had a serial port for control. There are remote apps that use Wi-Fi with a phone. Openhab has some documentation for controlling TVs using a serial protocol.
Larry has a Lenovo Yoga 720 convertible laptop, but when he plugs it into a dock, it doesn't show the bottom part of the screen. However, when he uses it in tablet mode, it's fine. Leo suspects that the monitor driver for the computer monitor is wrong. If it's using a generic driver, it won't show the whole screen. In this case, go to the monitor's website and download the latest drivers. Also, look in the monitor settings for "under scan" and enable that.
Paul has an IOGear KVM switch to plug in his laptop to connect it to his desktop monitor and keyboard. Leo says he'll want to be sure he uses HDMI for the video connection. But he can certainly use it with his laptop and his desktop at the same time. He'll also need additional cables.
Gary got an Insignia HDTV, but it won't let him directly enter channels on the remote. Leo says that at under $200, it's likely that the TV doesn't have direct channel entry on the remote control and it was done to cut costs by reducing features. It may not even have a tuner. He would need to use his cable or streaming box that has a tuner built-in that could do that.
