Gaming Monitors: How to choose the best monitors for sim racing

sim rig featuring triple monitors

Broadly speaking, sim racers have three options when it comes to gaming displays: one single monitor, a triple-screen setup, or a virtual/augmented reality headset, such as the Valve Index.

While each of these options has its advantages and disadvantages, in this guide, I’m going to be setting aside the VR headsets and focusing purely on monitors. Picking a new gaming monitor can be challenging because there’re lots of confusing numbers being thrown at you by manufacturers, as well as some discrepancies with regards to marketing terms.

Read on for advice on how to choose the best monitors for sim racing and what technical specs to look out for, or for monitor recommendations use the links below:

My aim here is to empower you to know how to pick the best monitor for your circumstances. The monitor or monitors you choose will be based on factors like how much space you have, how much power your GPU has, and your budget. I’ve covered aspects that I think are essential and shed some light on the technical jargon that surrounds display units, such as top resolution, refresh rate, etc., so hopefully, this will help you choose the best display solution for your rig.

Should I choose single, triple-screen or ultrawide gaming monitors?

Whether you plan to go down the single or triple-screen route is your call. One thing I would like to point out, however, before we get started is that triple-screen monitor setups help increase a sim racers immersion and their awareness of their surroundings by increasing the size of the visual field around them.

To demonstrate, you must imagine what the correct field of view would look like on a sim rig with a single screen. You will likely only be able to see what’s directly in front of you, and your view will be limited to the width of the car’s windscreen. It’s drivable, but racing in close quarters is a bit awkward, to say the least.

If you add in two extra monitors, everything looks a bit more natural. You can see the side mirrors and generally have a better sense of what’s around you in the car, much like in a real car.

However, that increased immersion always comes at the cost of performance. It s also possible to expand your field of view with a single screen by choosing an ultrawide or super ultrawide monitor, and I’ve covered some of them below, however, you still won’t reach the levels of immersion three screens can offer.

What technical specifications should I be looking out for in a gaming monitor?

Screen Resolution

One of the significant factors to consider when choosing a new display is the screen resolution. Depending on the PC and GPU you own you should always try to choose the highest resolution and the fastest refresh rate possible. Most modern gaming PCs can easily handle 1440p triples.

More and more buyers are moving to 4k gaming, largely becuase the price of the monitors themselves is falling.

Here is a breakdown of the screen resolutions you’re likely to see advertised when you begin searching for a new monitor:

ResolutionManufacturer monitor category name
1280×720HD / 720p
1920×1080FHD (Full HD) / 1080p
2560×1440QHD/WQHD (Quad HD) / 2K 1440p
3840×2160UHD (Ultra HD) / 4K 2160p
7680×4320FUHD (Full Ultra HD) / 8K 4320p

Frame Rate and Refresh Rate

Frame rate is measured in frames per second (FPS). This is the frequency at which consecutive images called ‘frames’ appear on a screen. Ideally, you’ll want to aim for a steady 60 FPS as an absolute minimum for smooth gameplay.

The refresh rate of a monitor is measured in hertz (Hz) and is the number of times per second an image displayed needs to be regenerated to prevent flicker when viewed by the human eye. This is independent of frame rate, which describes how many images are stored or generated every second by the device driving the display. If your GPU can regenerate an image to a 120Hz monitor 120 times each second, you’ll enjoy an excellent viewing experience. However, if your PC isn’t able to power through a demanding game, you will see stuttering and possible screen tear as the monitor and GPU become out of sync.

What is response time?

Response time is a millisecond value and represents how rapdily a monitor can update a pixel from gray-to-gray. In today’s money, a response time of more tham 1ms is disapointing for hardcore gaming monitors.

FreeSync and G-Sync

FreeSync (AMD) and G-Sync (NVIDIA) are proprietory graphics card communications protocols that allow a variation in refresh rate to keep sync with the frame rate of the game render. These systems are not corss compatible, so you need to check for FreeSync or G-Sync when you’re buying a monitor and of course, it entirely depends on your GPU manufacturer.

Tech Summary

An ideal monitor for sim racers would be the chosen resolution and screen size to fit your budget and spatial requirements, with 120Hz or higher refresh rate, and two Ms or lower response time. Plus, either FreeSync or G-Sync support. Of course, when you begin to enter into the 2K and 4K market, finding screens with these stats is going to get very pricey.

Lastly, I’d like to mention that while some 8K monitors are starting to appear on the market, the response times and refresh rates of these screens is still relatively low. So, in my personal opinion, when it comes to selecting a monitor for sim racing where split seconds can make all the difference, it would be better to hold off on buying one of these until the technology catches up to that of their lower-resolution counterparts.

Single Screen Monitors

A considerable advantage to single screen monitors is their simplicity. By that, I mean, they require little to no configuration when compared with a triple-screen setup. Should you decide to opt for a single screen, your main choices are going to between flat or curved screens, and of course, all the technical specifications in our tech summary above.

There’s also the choice between regular, ultrawide, and even super ultrawide aspect ratios, plus flat-screen or curved screen options.

Here are my recommendations in each category:

Ultrawide Gaming Monitors

Ultrawide monitors are capable of offering a better experience than a single, large 16:9 ratio screen for sim racing. Fundamentally you have a wider screen which means that your FOV (field of view) can be so much wider. In sim racing, you can improve your use of vision, which makes for cleaner and more accurate driving. I love my Samsung G9 which as genuinely been a game-changer for my own sim setup.

You also get more pixels! A good, high resolution 16:9, 27″ display running at a resolution of 2560x1440px displays 3.6 million pixels, whereas a 34″ 21:9 display displays 4.9 million!

Best Triple-Screen Monitors

Setting up triple monitors for your sim racing rig isn’t all that complicated, and it doesn’t require too many parts, but getting the right parts is pretty much crucial. First of all, you’re going to need three single screen monitors, and ideally, these should be identical. It is sometimes possible to use different models, but you will likely run into issues with color and refresh rate matching across your screens. Also, you may find that correcting for mismatched bezels is difficult, and honestly, it’s more trouble than it’s worth.

Aside from the usual things that people look at with computer monitors like refresh rate and response time, you need to think about resolution and size a little more critically if you’re setting up triple monitors on a sim racing rig. The larger your screens are, the further away you’ll need to place them, which takes up more space, but if your screens are too small, you won’t get the benefits of immersion.

The prevailing wisdom is that achieving a roughly 180-degree field of view (FOV) is optimum. Essentially this means that the far edges of your two side monitors should be in line with your eyes.

The next consideration is the resolution. 1080p is still the default when it comes to triple screen setups, but 2K and 4K screens are becoming a lot more commonplace. You may be tempted to look at those options. Still, you need to be aware that small increases in screen resolution multiply to create relatively large increases in the total number of pixels that your video card needs to render.

Samsung CJG5 Series 27-Inch WQHD (2560 x 1440) 144Hz 4ms Curved Gaming Monitor

A triple 1080p setup has roughly 6 million total pixels, while three 1440p monitors weigh in at nearly twice as much, and three 4k monitors have over two times the number of pixels of a 1440p setup. The relationship between frame rate and the number of pixels isn’t linear, but you can make some educated guesses. If your rig manages say 80 FPS on a single 1080p monitor, then it’s going to struggle to render 12 times the number of pixels on a triple 4k setup. The takeaway from all this is that if you want to run a triple-screen monitor setup above 1080p, you’re going to need a rather powerful GPU (likely an RTX 2080 ti or higher).

On the topic of GPUs, having one that provides enough ports to drive three monitors is a must, so make sure to check the connectivity of your GPU before you decide to go ahead and buy yourself three new monitors.

Here’re some great options for a triple-screen setup:

Premium 4k UHD displays

If you want to go for the very best that modern monitor technology can offer, then these 4k, HDR screens are at the paramount of what’s available. With ultra-fast refresh rates and up to 8.3 million pixels (on a 3840 x 2160px resolution 27″ screen) – your screen will be bursting with incredible detail and colour. Especially the replays! Naturally, if you’re looking at running triple monitors with a screen resolution as high as 3840 x 2160px each, you will need a proper graphics card. We’d recommend a NVIDIA 3080 rtx as a minimum and if you can stretch to it, the 3090. Even at that resolution, a 30xx card would barely break a sweat in iRacing!

BEST: LG 27GN950-B

LG’s 27 Inch, UHD 4k (3840 x 2160) resolution LG 27GN950-B monitor offers an incredible pixel density of 8.3 million pixels. Featuring LG’s Nano IPS Display and a fast 1ms response time at a 144Hz refresh rate. Features G-SYNC Compatibility.

Tom’s Hardware voted this screen the best 4K gaming monitor in 2021 and it’s our top recommendation too. It has literally the fastest input to display lag time on the market; it’s ultra fast!

The monitor offers extremely high image quality with its edge array backlight and a local dimming Nano IPS panel (equivalent to Samsung’s Quantum Dot technology). Color coverage is huge (94.5% of DCI-P3 and 133.9% of sRGB) so you’ll have an exceptional HDR display that looks incredible that really makes your replays stand out.

Asus ROG Strix XG27UQ

Asus ROG Strix XG27UQ

ASUS’s ROG Strix XG27UQ DSC gaming monitor is a 27-inch 4K UHD with the same resolution and pixel density as the LG (at 3840 x 2160px). It has a refresh of 144hz, it’s G-Sync and Adaptive-Sync compatible, offering DisplayHDR™ 400 and a DCI-P3 of 90%.

The ASUS rates as one of the best 144hz 4k gaming monitors available on the market and again would make an incredible triple screen setup, but it is slightly better priced than other premium monitors.

It doesn’t have the same backlight technology of the LG monitor, but it is excellent thanks to the Shadow Boost technology and the black display it’s capable of. Priced at around $800 per unit; it would make a fearsome triple setup in your sim rig powered by a powerful enough GPU.

Bezel Free Kit

Bezel free kits are accessories that enable sim racers with triple screen setups to virtually eliminate the black gaps between screens created by the monitor case (the bezel). The kit essentially creates the illusion of a single monitor rather than 3 separate monitors. The ASUS ROG bezel-free kit contains special optics that refract light, bending it inward to hide the bezels underneath:

The material the manufacturer uses lets about 90% of the light from the monitors shine through what is basically an angled plastic corner, that clips in place. This makes the picture between the lenses slightly dimmer than the rest of the display but somewhat less distracting than the opaque seams created when two bezels are next to each other.

Monitor Stands and Mounts

The next consideration is how you’re going to mount your monitors. If you race at a desk, this is likely something you won’t need to think about too much, but if you have a standalone rig, you’re going to need a monitor stand. These come in several shapes and sizes, but in general, they’re designed to stand over your rig and allow you to adjust the height, spacing, and angle of your monitors.

This is an area that’s going to vary a lot depending on your requirements, and it’s something that I would put a reasonable amount of time into during the planning stages. It’s essential to make sure that whatever stand you choose can cater to the sizes of your screens. With that said, here are some great choices on the market to suit different types of setups.

GT Omega Simulator Triple Monitor Stand
