Project: Spectrum | Mass Production Imminent

smpib 690x193

Beloved community,

Spectrum is going mass production (MP)!! I just received my second tripod specifically ordered to capture this milestone and am readying all gears for the whole-day factory video shoot tomorrow. Before I carry all the excitement to my dream tonight, I have an update for you.

Mature firmware

The team has shaken hands on the functions offered by the shipping firmware, which will, in turn, provide a good out-of-the-box user experience when you receive your Spectrum. Our confidence is backed up by the extensive professional testing by our quality and reliability engineering (QRE) team and the hands-on involvement of our community testers. Upon our confirmation, the firmware is immediately sent over to the printed circuit board assembly (PCBA) factory, where it starts to be integrated with the PCB. With this first step out of the way, the PCBA factory will continue manufacturing for the MP assembly line. Our focus has shifted to leveraging our firmware’s user-upgradeability to deliver the most meaningful new features and bug fixes in the shortest possible time. As the firmware further progresses, our community testers will continue to receive the latest development builds to provide insider feedback to the team. Each firmware update will only be released to the public after being proved stable through our QRE testing.


sRGB mode

Spectrum’s customized factory calibration tool brings support for a functional sRGB mode. Compared with the DCI-P3 mode, which maps the display to the wide P3 color space, sRGB mode restricts the color gamut only to cover the smaller sRGB color space. Non-color managed applications such as most web browsers, video players, and photo viewers typically treat all monitors as a standard sRGB display, even after performing a proper software calibration. A factory-calibrated sRGB mode ensures good color accuracy in these applications at a hardware level. Even though sRGB monitors allow all kinds of adjustment to the picture settings, it is common among wide gamut monitors that little to no customizability is allowed in sRGB mode. In contrast, we have enabled brightness, gamma, and sharpness adjustments in the OSD when sRGB mode is selected, so you can freely tweak it to your liking. We are working on bringing the sRGB mode customizability up to the level of the DCI-P3 mode by arranging firmware codes to memorize the different user-defined contrast and color temperature settings. New progress will come to our customers as a firmware update later down the line.

Backlight strobing

An LCD panel takes time for a pixel to transit from one color to another (response time); even for those panels reaching single-digit milliseconds grey-to-grey response time, this transition introduces blur when viewing moving content. Backlight strobing hides pixel transition time in the period when the panel backlight is completely turned off to improve motion clarity drastically. In Spectrum’s firmware, three settings are working in harmony to achieve a great backlight strobing experience:

Pulse width

It determines how long the backlight is turned on within each of Spectrum’s refresh cycles, providing a trade-off between brightness and motion clarity.

Pulse phase

It defines the position where the pulse starts, which can be shifted in 1% installment until it reaches the beginning of the next refresh cycle.

Overdrive gain

This refers to the amount of current being pushed into the pixels to speed up the response time.

We plan to continue working with Mark (@Blurbusters) on implementing strobed Adaptive-Sync. This will allow our users to experience the best of both worlds by having backlight strobing and Adaptive-Sync enabled at the same time. With it, we will also look into embedding dynamic overdrive for Adaptive-Sync, which allows the overdrive gain to be adjusted based on the panel’s refresh rate.


Spectrum is the world’s first PC monitor with a built-in integer ratio upscaling. As has been confirmed by our community tester Marat Tanalin, popular resolutions such as 1920×1080, 1280×720, 1680×1050, 1024×768, and 800×600 already function correctly. We will work closely with Marat on tuning Spectrum for an even better pixel-perfect integer scaling experience by adding older TV resolutions to support more retro games.

In my intended usage scenario, I want automatic USB switching. How will the Spectrum know which USB upstream port to associate with which input source?

i.e., I want the USB-C upstream port selected when I use HDMI1 (or HDMI2), and I want the USB-B upstream port selected when I use DisplayPort.


This will change the delivery dates?

I believe (and Eve can correct me if I’m wrong) that the automatic USB switching is only when using USB-C as one cable solution. i.e. plug your laptop in using type c port to get display and auto switch your keyboard and mouse (or other device plugged into Spectrum) to the laptop usb connection.


@wizard_auz The current automatic settings are currently configured for Type-B to be mapped to HDMI & DP, and Type-C mapped to Type-C. We’ll explore the possibility of user customization of this setting later down the line.

The shipping for the 4k 144hz model is still due to commence from the 29th of this month!


This is overall great stuff. However, is the stuff that’s not currently implemented (such as split-screen mode or crosshair displays, which would be great for me), still being implemented?

I’m definitely looking forward to seeing what you’re able to make of the adaptive-sync strobing, which would be a killer feature, but difficult to pull off if what Mark said in his post is true. Can’t wait to finally get this in my hands.


Split-screen mode is currently being worked on, and will be implemented at a later date. The crosshair feature is currently working in the latest firmware, but different crosshair selection will also be implemented in a future firmware update.


It’s looking really good and with some other features that will come later. I am a huge fan of being able to not only change the crosshair type but also the color as I love to use this when I practice my aim while gaming against bots.


any updates for the 1440p panels


Are we going to be able to change the ‘size’ of the cross hair overlays as well?


Any idea if any of the community testers are going to do proper colour testing? So far all I’ve seen are subjective opinions of “it looks vibrant” etc…

I do photo/video editing and work as a Product Designer so colour accuracy is important to me. It’s stopping me from committing to my final payment as I don’t want to push the button until I know how accurate it really is out of the box (due to lockdowns, it’ll be months before I can get a professional calibration if necessary).

Any idea on when/if we’ll see this? Otherwise will have to wait for a review from Rtings.



Looking at the OSD again, I wonder whether the indicator light settings would be better off with an HSL setting instead of RGB. Generally I’d want to either go from one color to another color at a similar brightness, or keep the same color but increase or reduce brightness.

With an HSL scale, I would only have to modify one or perhaps two sliders instead of changing values for all three. That seems much less annoying on an OSD, where you can’t just easily paste hex codes from a color selector and instead have to use navigation and sliders.


Hey, @Cad! We’ll see what we can do when it’s time for us to implement the crosshair overlay better.

I believe our tester Niraj (@nkyadav) has got himself a colorimeter; perhaps it’s a good idea to poke him for some color testing!

The measurement from our factory calibration tool shows that mass-produced Spectrum units have around 0.5 to 0.6 average Delta E after assembly line calibration. The display follows the 2.2 gamma curve correctly and has a D65 white point for the ‘Normal’ color temperature preset.

It’s a good point! We can take it into account if we do a Spectrum redesign in the future.


Is there an option to turn off local dimming?


Global dimming is an option when in SDR. In HDR the signal requires some form of local dimming. However I think from our tester discussions in Discord they’re looking into being able to turn off local dimming in HDR.

@Lore_Wonder correct me if I’m wrong!


Super awesome job you guys! So I was thinking something, and this might come at an inconvenient time so bear with me.

Is it possible that EVE will and can develop a specific software for the monitor, that allows for screen colour space/general settings to be adjusted?

Much like Dell has a software that does that? I don’t know if there exists thirdparty software that already makes that possible for any monitor, but thinking that EVE Spectrum is a highly costumized monitor I would assume it’d require costum software likewise?



Hey, I just posted in my thread about this:

Please feel free to add anything you want to there!


As a third party supplier of blur-busting adjustment software for multiple vendors (including Eve), I’d like to chime in.

Long term, our multivendor Blur Busters Strobe Utility codebase is designed to be extensible to add other DDC-commandable picture adjustments.

There is no timeline yet for this general-purpose picture adjustment feature (blur busting strobe-backlight features are Blur Busters business bread and butter). It uses a text-based configuration file (INI) that will be designed to be editable to point to arbitrary DDC commands, and shareable to other users who wants a custom configuration file.

Once this happens, we also have a new name for the utility when it becomes more general-purpose than a Strobe Utility. We are merging an old Configurator utility we had built for a different independent (non-vendor-specific) project, into this codebase.

In the interim, the converse is also possible for other utilities – Eve strobe tuning DDC commands are 0xE0, 0xE1, and 0xE2 for Strobe Phase, Strobe Width, and Overdrive Gain (during Blur Reduction) if you want to custom-configure your favourite DDC utility (SoftMCCS, Linux ddcutil, etc).


About the start of VRR strobing work, I’ve now posted a behind-the-scenes piece on this:


Love reading all the comments and this update was very informative. I’m so looking forward to having my 4K Spectrum as it’s main use for me will be gaming on the series X and some gaming on my PC. I’m not as technically sound as some in our community so I’m learning new things about stuff as well. Again being part of this project to me was a great decision for me as I look back on how bad the year 2020 was. Looking towards the future I wish everyone in this community the best and I will for sure post an update on my personal user experience once I have the Spectrum myself. Thanks again Team Eve and God Bless
