When it comes to work and PC gaming, there’s nothing quite like using a massive monitor.

Resolutions have climbed in recent years to the point that the best monitor manufacturers have begun offering some seriously impressive options that still have suitable DPIs for a PC setup.

But the biggest monitor doesn’t always mean the best quality.

So, today’s feature is here to not just here to guide you through the largest computer monitors, but also the ones worth buying for gaming, work, and more (with many budgets in mind).

Top Picks

Best of the Rest: Quick-Fire Picks

Largest Computer Monitor: Asus ROG Swift PG65UQ

We’ll start by saying for many users (business/gaming focussed alike) we don’t think this size is necessarily the best pick-up, which is why we’ve focussed on 43″-55″ monitors in most of this feature.

We also think that our next OLED TV choice will likely suit a majority of PC users better for far less cost if you do want an enormous size.

With that said, no list of the largest computer monitors would be complete without the PG65UQ.

Boasting an incredible 65″ size alongside its 4K resolution, DisplayHDR1000 capability, 144hz refresh rate & 95% DCI-P3 & 4ms GTG response time, this monitor has some fantastic capability not just as a gaming monitor, but one suitable for media & general use at the highest level.

With G-Sync ultimate support, the monitor has great capability for avoiding v-sync/ghosting issues; this is integral for a display of this refresh rate/size, where screen tearing and other common issues are even more visible if no high-end screen sync technology is in place.

The build quality is also everything we would hope for in a premium monitor; with a sturdy design that feels built for longevity, not to mention incredibly thin bezels and a subtlely tasteful ASUS logo illuminating underneath the monitor

So with all that said, why do we suggest something slightly smaller?

Well, although the PG65UQ is a beast, we assume that most reading this list will be looking for a PC monitor for gaming, media, or business/general use.

While it fits nearly all the specs perfectly, there is one problem; 2160p resolution may be a lot, but at 65-inches, it begins to slightly show with a lacking DPI at this enormous screen size.

If you’re in the market for a premium monitor, we expect you’ll be after sharp text and crisp game detail even while sitting relatively close. If this the case, our 43″-55″ monitors are the better choice, boasting the DPI we think is more suited for a PC experience.

If, however, you’re primarily after a monitor for gaming from afar with a console, then that issue is largely negated.

But there is another lacking area for you; there is no HDMI 2.1 output.

HDMI 2.1 introduces significantly better bandwidth rates and empowers you to play at high refresh rates/resolutions on PS5/Xbox Series X, to buy a monitor of this caliber without it seems wasteful for console gamers (if you’re focussed on PC gaming from afar with DisplayPort, then we have no qualms, and this is a great choice).

If you are in that console-gamer category, or a PC gamer who isn’t opposed to an OLED TV as a primary monitor, we would instead highly recommend the LG CX OLED pick a little further down.

For a significantly smaller price tag, you are getting an HDMI 2.1 display that excels in picture quality, contrast, while also put together to counter the usual complaints about using a TV as a monitor (i.e. very high refresh rate and low latency).

Although this all sounds like a negative take, we do in fact, really like the PG65UQ. We just think the next pick trumps it in a majority of ways.

If your singular goal is the largest computer monitor possible and you would like to avoid an OLED TV for your setup, then this is the choice for you.

Its DPI may be a tad low, but with its fantastic HDR, color and refresh rate, it’s still a fantastic gaming monitor and beautifully encapsulates so much of what you want in a big format gaming display/BFGD.

Largest OLED TV for Gaming or Work: LG OLED55CXPUA

We alluded in the top pick that for console gamers focussed on a premium experience, this OLED TV choice will be better for you than the other options on the list.

That said, this isn’t just for console gamers; if you’re not a user concerned about the effects of OLED burn-in, we think this is arguably the best choice for nearly any user after an extra-large monitor.

This includes those after a monitor for media, general use, or business work: we expect you to be pleasantly surprised by what’s on offer here.

If you haven’t experienced an OLED before, it’s hard to describe just how incredible the endless contrast ratio can look versus traditional LEDs; with the deepest blacks, not to mention this LG TV having an incredible color range, the picture quality available here is the best on the list.

For general/work use, the sharp contrast is perfect for displaying anything from documents to media, to trading/production software in crisp detail.

Now, the worry with a TV for use with gaming and as a PC monitor replacement is its latency/refresh rate.

But LG has impressively innovated a massive 4k screen that boasts 120hz, G-Sync/Freesync support, and response times as low as 1ms.

We really can’t articulate just how good you can expect your content to look on this screen, with these secondary specs essentially completing negating what often makes TVs worse than monitors for PC users.

And for console gamers, this TV supports HDMI 2.1 which is integral to gaming on high refresh rates/resolutions with the latest console generation.

The screen is amazing in lots of ways, but this alone is why we rate this LG TV as superior to any extra-large monitor for console use.

Whether you’re focused on immersive titles, competitive gaming, or non-gaming content, we think the LG CX ticks pretty much every box.

Size-wise, the largest available is as high as 77-inches, larger than the biggest PC monitor available today.

For most users, we would recommend the 55-inch (at a stretch 65-inch) if you plan to be up close and use it as a monitor replacement due to the decreasing DPI at the top sizes (if you plan to mainly consume content from further away, however, any size is great!).

You may have also noticed that compared to a comparable PC monitor like the Alienware 55-inch AW5520QFthis LG TV runs at around half the price.

So, with all of this excitement, there is one caution to mention: OLED TVs carry the risk of burn-in, and the LG CX is no exception.

Burn-in can occur when certain pixels (especially bright colors) are set in the same position for a long period of time over many usages.

Due to the way OLED TVs are created, this can create a slightly transparent permanent “etching” of those pixels.

For TV/console gamers, the issue is almost moot as your content will always be moving: the main concern here is when used as a PC monitor, most notably the Windows 10 logo in the bottom left is the main risk for minor burn-in. Or, if you’re a gamer focussed on a single title (e.g. a MOBA or MMO with a static UI) you may carry some small risk.

We’ll be clear though, this is a very minor risk (we wouldn’t be featuring it if it was a more emergent issue), burn-in is reminiscent of plasma TVs; yes it’s possible, but as long as you’re not leaving your monitor on all the time with the exact same pixel arrangement in certain areas (i.e. turning off/running a screensaver during idle moments) then the immense cost saving of the LG TV over the more expensive monitors will serve you very well.

Finally, while not straying away from the traditional TV design conventions, the LG CX looks very sharp, understated, sturdily built, and incredibly thin (it’s heavy at larger sizes, but still capable of VESA mounting).

So, with everything said, the LG CX doesn’t just offer the largest PC monitor replacement available with an incredible picture but also does so at a fraction of the price compared to the enormous monitor offerings.

If you can get on board with using a TV as your monitor/gaming solution, we think you’ll love the LG CX.

Widest Computer Monitor: Samsung Odyssey G9

Moving away from the largest 16:9 screens, Samsung instead positioned itself in the market with a focus on super ultrawide screens.

And what an incredible offering it is.

This naming convention may sound like a gimmick, but it refers to the 32:9 aspect ratio of the Odyssey G9. With a 5k resolution (5120 x 1440), this 49-inch monitor is the size of 2 1440p 27-inch screens in 1.

As far as work, general use, and other typical PC applications go, the utility of this is obvious; super ultrawide screens are perfect for productivity and multitasking.

While we recommend a Dell 49″ 32:9 screen further below that’s tailored for work, we think the Odyssey G9 is more than capable of a fantastic business use setup (and is notably cheaper than the other offering).

But it’s gaming where the Odyssey G9 really shines.

With a 240hz refresh rate, 1ms GTG response time, G-Sync/FreeSync Premium Pro support, HDR1000 capability & fantastic colors through its QLED IPS panel, the specs for gaming are incredible.

With the plethora of titles that support its UWQHD resolution. Playing immersive games in a 5K UW resolution is an experience that is hard to describe, and we love that the G9 also boasts all the specs perfect for more competitive/esports-focussed users.

This is also the largest curved monitor available, with 1000R curvature, this rating is the strongest curve you see on mainstream offerings, suitable for users after the highest sense of immersion (and with the wide aspect ratio, the G9 feels like it engulfs you in your content; it’s quite a sight to behold.

Note: although we are discussing the G9; its 120hz brother, the CRG9, is a fantastic offering at around 15% less expense. Do we think the 240Hz refresh rate is worth the extra price for gamers? 100% But if you are price-focused, the CRG9 is still a premium gaming monitor in its own right (and if you are solely non-gaming focussed, it’s the better choice).

We’re simply floored by what an incredible offering the G9 is. No other screen encapsulates the kind of innovation we want from a high-end monitor like it.

This isn’t just the widest PC monitor, but the best out of the competitors in the super ultrawide space.

If you prefer the immersion/productivity possibilities of 32:9 over a larger 16:9 screen, then you’re going to really appreciate what this Samsung offering can do.

Largest Monitor for Work: Dell U4919DW

As much as we gush about the Odyssey G9, there are certainly some other fantastic super ultrawide monitors available.

The U4919DW is the other one we think is worth highlighting; designed as both the largest & widest monitor for business/general use.

With its 5120×1440 resolution & fantastic contrast/color gamut, the display looks as crisp as you would hope for anything from spreadsheets to video calls.

The real question is if you will prefer this to the CRG9/G9, and that comes down to a few areas.

Firstly, and perhaps most importantly, the U4919DW boasts significantly less curvature with a rating of 3800R.

This has been designed because Dell expects business users to share content more and this curvature is more accommodating to larger viewing angles. A flatter screen can be slightly more ergonomic for “flat content” like spreadsheets (where games can benefit from the dramatic curve of the G9).

The monitor also proudly boasts its KVM capabilities, which empowers a user to connect 2 PCs at the same time to the monitor (the G9 can also do this, but the instructions are a little less clear because it isn’t marketed for work).

Not only is the picture great, but it’s also designed to accommodate business/general use (while the Samsung CRG9 is preset for gaming, you’d need to tinker with the settings to get an optimized screen for work purposes).

The thing that disappoints us with the U4919DW over its Samsung competitor is its price.

It’s certainly a high-end monitor worthy of a premium budget; but the Odyssey CRG9, with its more impressive specs across the board, is a cheaper offering.

With that in mind, we think it’s worth going for the CRG9 over this Dell pick in a lot of cases, even if you are not interested in its gaming capabilities.

That said, if easy KVM functionality, no picture-setup requirements, less curvature & better viewing angles are important to you (and gaming isn’t), the U4919DW is your best large monitor choice.

Largest 16:9 Monitor Cheap Option: Philips Momentum 558M1RY

If you’re focused on a 16:9 monitor for gaming or work, but don’t have the budget for the largest screen at the top of our list and aren’t happy with an OLED TV as a replacement option, the Philips Momentum series is the best choice for you.

Still an enormous 55-inch monitor, the 558M1RY boasts some excellent specs across the board at a significantly reduced price tag compared to our top ASUS offering.

With UHD resolution, 120hz refresh rate, DisplayHDR1000 capability, AMD FreeSync Premium Pro (G-Sync seems to run unofficially too) & 4ms GTG response time, the specs are excellent across the board.

We also appreciate how the monitor manages to retain low latency even with HDR enabled, making it an incredible choice for immersive gaming titles.

One of the surprising USPs of the 558M1RY is its fantastic speaker setup.

On TVs and monitors alike, getting a standalone sound solution is nearly always the best bet. But here? You have a perfectly legitimate audio offering as far as gaming/media goes, with a Bowers & Wilkins-designed setup that emulates surround sound and boasts an integrated woofer.

Note: Through various user experience, we’ve noted that installing the latest drivers for this choice are integral when using as a monitor (to ensure display/text sharpness).

For console gamers, there is no HDMI 2.1 here and we still highly recommend sticking to the LG OLED TV choice for your needs (unfortunately, there seems to be very little HDMI 2.1 availability amongst the biggest monitors).

It’s worth also touching on the quality and design of the 558M1Ry too; with an incredibly sturdy build that feels deceptive considering its tiny bezels and ultrathin depth, it’s one of the most beautiful monitors available.

55-inches is still a massive monitor, and with the Philip Momentum’s superb specs, this is a great choice for a high-end setup that demands some of the biggest PC display visibility for gaming or work.

Alternative Picks – Best of the Rest

Although the above choices are our absolute top picks for the biggest PC monitors today worth buying, we want to recommend some quick-fire options for users who:

  1. Run into stock issues with the above (these other choices are excellent alternatives).
  2. Want a large computer screen, but not quite as large as these, with some 40-inch monitors below.

Largest OLED Monitor: Alienware OLED AW5520QF

With the low latency of a PC monitor and the unrivaled contrast of OLED, this Alienware screen is a pricey, but stunning offering.

Largest 4k Monitor for Work: LG 43UN700-TB

If you instead want a 16:9 screen specifically tailored for work/high viewing angles, this 4k display is beautiful and very capable with non-gaming content.

Its most impressive USP is its ability to operate as a multi-client monitor, capable of running 4 1080p screens simultaneously.

Best 43-Inch Gaming Monitor: Asus ROG Strix XG438Q

If you were surprised that our largest monitor picks got as big as they did, you may appreciate the XG438Q; while still an enormous screen, it’s certainly not as all-encompassing as our top picks but just as high-quality.

If you would prefer even smaller, most of our other monitor features specialize in picks between 23 & 32-inches.

Cheapest Large Screen: ViewSonic VX4380-4K 43″

If you want a huge computer monitor for a fraction of the price, ViewSonic is the best brand in the business for offering the cheapest price tags.

Its picture/latency will be a tad less impressive, but it’s still an excellent value offering.

Cheapest Super Ultrawide Display: VIOTEK SUW49C

If you liked the sound of the Samsung/Dell superwide monitors but can’t stretch to them, Viotek is a great brand for offering a budget version of high-end gaming monitors.

We don’t love it quite as much as the G9, but it’s still an excellent large PC gaming screen.

Largest 5K Monitor Alternative: LG 49WL95C-W

Filling nearly an identical need to our top Dell recommendation, this wide monitor from LG is a compelling alternative.

We only rate it lower because its availability is historically not as decent, but if you are work-focussed and it is in stock, we think you’ll enjoy its capability.

Best 65 Inch Monitor Alternative: HP Omen X Emperium

Finally, if your heart is set on the largest monitor in the world, but our ASUS pick is unavailable, the HP Omen X Emperium is a great alternative.

Final Word

And there you have it! After deliberation over everything from DPI to color gamuts to build quality, the above are our top picks for the largest computer monitors worth buying today.

If you were looking for a 75-inch monitor, 100-inch monitor, or something even crazier, you may be disappointed to see that the largest PC displays available don’t go quite that high (unless you count the LG OLED 77-inch choice).

We would say, however, with the current 4k alignment with mainstream options, getting a PC monitor in the 43″-55″ range is the sweet spot, and where we recommend you to go for crisp content if you’re sitting up-close.
