ViewSonic VP2780-4K 27-inch Ultra HD Monitor Review

We've got ViewSonic's VP2780-4K in the lab today. Is this 27-inch, Ultra HD, IPS-based monitor worth your hard-earned money? Let's find out!

Conclusion

There is no doubt that Ultra HD is still a premium technology. The least expensive way to go is to select one of the 28-inch TN models for around $500. You’ll give up a bit of off-axis image quality, and size-wise, we still think 32 inches is the ideal form factor for such high pixel density. However, it seems that the new 27-inch IPS category holds some promise for those willing to spend about $850.

ViewSonic’s new VP2780-4K proves to be an excellent first-generation product in this new screen size. Most factory-calibrated monitors will cost you a tidy sum, but this one manages to deliver superb out-of-box accuracy and good value, especially considering each sample is individually calibrated and checked before being shipped.

We found in both the Native and sRGB picture modes that all parameters, color, grayscale and gamma were pretty much dead-on correct. And that includes the EBU color space, which is something you won’t see on most displays. We also measured excellent contrast of over 1000:1 in every test. The ANSI result is the most impressive, as it exceeded that of many other pro screens we’ve tested.

The only flaw here is in the VP2780-4K’s calibration system. Basically, you're stuck with the preset modes that have no adjustments available, save brightness and contrast. If you engage the User mode, you can achieve almost perfect grayscale, but then you introduce gamma problems that render the color gamut inaccurate. Our hope is that ViewSonic, through a firmware update, will simply make the gamma presets available in that mode, which should fix the problem. For now, users wanting to do better than the factory calibration will have to resort to software like CalMAN to create an internal lookup table.

A nice bonus we weren’t expecting was the VP2780-4K’s low input lag. We’re not talking about 144Hz gaming monitor numbers, but for an IPS panel of any resolution, this screen is pretty quick to respond. At 63 milliseconds, it trounced nearly every 60Hz monitor we’ve ever tested, regardless of resolution or panel type. Of course, if you want the ultimate experience, we still recommend G-Sync or FreeSync coupled with a speedy panel. But since Ultra HD at 144Hz is still a dream at this point, gamers desiring a 3840x2160 display should look hard at this ViewSonic.

For its super-accurate color, excellent contrast, great build quality and unexpected speed, we’re giving the ViewSonic VP2780-4K our Editor Approved award.
