ASUS got in touch with me the other week and said, "Hey, would you like to see our new monitor?" And I thought, sure. Monitors are cool. Tech is cool.

But this isn't a monitor. It's more like a TV.

Dear Lifehacker, I recently installed a new graphics card and realised that my monitor, which uses VGA and a DVI-I converter, won't plug into the graphics card's DVI-D port.

Mac: If you have a multiple monitor setup for your Mac, you know that the simple act of disabling the extra monitors when you need just one is a little cumbersome. Screen Commander makes it easy.

Dual monitors are useful for a lot reasons, even if they don't actually affect productivity. Buying a second monitor is straightforward if you're working from a desktop computer, but it's much trickier with a laptop. YouTuber DIY Perks shows you how to build a second monitor from recycled parts that works great with a laptop.

You may have just gotten used to HDMI 2.0, but HDMI 2.1 is already on its way, and it has all kinds of awesome new features. Here's what you need to know about the substantial update.

If you want the ultimate in desktop screen space, you have two options: Get a bigger monitor, or get a 4K monitor. Both options offer you more space to spread out and work, and more pixels to cram your windows into, but two are the focus of many monitor-buyers today: Ultrawide and 4K. Let's see how they stack up, practically.

I moved a few weeks ago, so I had to break down and re-set up my workspace. When I did, I replaced my dual-display setup with a new 34" ultrawide LG curved display. It's had its quirks, but now I'm not sure I could ever go back. Here's why, and why it's worked so well for me.

Apple recently discontinued its standalone Thunderbolt display, which sucks because it was one of our favourites. To soothe the wound, here are some of the best monitors we've found to replace Apple's dearly departed display, most of which offer similar features without the price tag.

Dear Lifehacker, I need a new monitor that I can use to play console games -- Xbox One and PlayStation 4. I want it to be around 26 to 32 inches, and I don't want to pay more than about $300. Any suggestions?

It's not just the iMac: Many monitors place their USB ports in the back, where they're difficult to get to. Use Sugru and magnets to hide an extension cable within easy reach.

Super high resolution displays are becoming more common on Windows laptops, but densely packing pixels into a small screen comes with some trade-offs. The resulting image can be great -- text looks smooth and high-quality images are stunning -- but not all applications are designed to run at high resolutions, making for a very mixed experience.

We love multiple monitor workstations, but "Ultrawide" displays, packing resolutions that rival two or three panels side-by-side, are looking better and better these days. After all, having more than one monitor doesn't automatically make you more productive. Here's how these new ultrawide monitors differ from a dual-screen setup, and when you might consider buying one.

Many of us are stuck behind our desk and computer all day long, which makes the hardware we use quite important. Let's give some more thought to our monitors, with these ten tips for getting the most out of those screens.

Using more than two monitors used to be a luxury for those with the biggest PC-building budgets. These days, large, high-resolution displays are affordable, and graphics cards are more powerful than ever. If the thought of gaming (or working) on three displays at once entices you, here's how to make it happen.

Even if an old laptop no longer has the speed you need, the screen might still be worth salvaging as an extra monitor. This DIY project takes you through hooking up the screen and shows a neat stand for it made out of Meccano construction toys.
