Project: Spectrum | ES07D02 Project Update IV


Hi there community!

Theo, the community reporter is back with another piece of news! With this topic, I would like to present another quick update on ES07D02 (Spectrum 280Hz matte). We are happy to share more news on the development. In this topic, you are going to see what is happening right now, what will happen, and what we had discovered along the way.

The progress so far

Taking over from our previous update, we have finally finished the design validation testing (DVT) and now entered the next phase, production validation testing (PVT). We have prepared a PVT build to continue with its quality and reliability engineering test. Things are moving forward!

At the same time, we still have safety and feature certifications along with backlight strobing tuning by Blur Busters. Both are still in progress ever since the last update and will go on parallel with the main development stages.

Interesting find

During DVT, there is one finding that we would like to share with you guys. One of our engineers found a small error in our DVT build that can be seen only at a certain angle. You can see it below:

Issue pic1 fix
Two small strips of light appear on both sides of the LED light. They are in the same proximity relative to the LED and do not look like an assembly error.

Upon investigation, it turns out that it was caused by a slightly different physical shape of the liquid crystal module (LCM) for our QHD 280Hz panel.

ES07D02 LCM fitted with its black box containing the mainboard. Indentation is present in the middle.

ES07D03 LCM. Notice the lack of indentation.

Since we are using the same external frame for ES07D02 as ES07D03, this extra indentation created a small gap where light can seep through. To prevent the light from getting out, we need to somehow cover the gap. Initially, we came up with two different materials to do the job:

  1. Foam tape
    With foam 2
    3M foam attached to the bottom part of ES07D02 LCM.

  2. Insulated black tape
    With tape
    Black tape placed on the bottom of ES07D02 LCM.

To make sure the material stays after normal usage, we conducted a heat test. Two units were fitted with two different materials to see how well they last under various heat profiles and humidity levels. After the test, we found that both materials performed quite well, but we decided to go with tape instead because it is much more solid and has less chance of fraying in the long term.

Compatibility test

Next on the menu for ES07D02’s development is the compatibility test. The main purpose of this test is to ensure Spectrum is capable of running and displaying input from a wide array of devices, from all possible connecting port combinations. To pass this test, Spectrum must be able to display all the common resolutions supported by both devices without any flickering, shaking, black screen, etc.

Compatibility test

There are more than 50 devices that were tested with the Spectrum for this compatibility test. It ranged from consoles, laptops, Apple macOS devices, and custom PCs of varying specs and operating systems. Even cell phones are part of the test! :smiley:

Depending on the device category, there are criteria for passing the compatibility test. They roughly follow the same rule, with slight variations:

  1. Gaming consoles
    There are 7 consoles for this test: PS3, PS4, PS4 Pro, PS5, Xbox One S, Xbox Series X, and Nintendo Switch.
    For each console, we have about 5 games to be tested, mostly AAA titles. To do the test, Spectrum must be able to display and support at least 30 minutes of uninterrupted gameplay for each game. So with roughly a total of 35 games to play, testing Spectrum’s compatibility with consoles took a lot of time. By the way, testing also includes playing in different video modes supported by the console, so it can take about a week just to test this category.

  2. Windows-based PCs
    Things are getting even more serious when PCs are involved since there are millions of possible hardware combinations. We have to admit, that it is simply impossible to test every single one of them. So instead we have more than 20 PCs that represent the global specification. When picking which PC we will use, we mainly base the decision on what processor is used, which graphic card, and what OS version is it running.
    For this test, we have included PCs with older Nvidia GTX 780, all the way to the most recent Nvidia RTX 3090. Onboard graphics were also included. Laptops and tablet computers also part of this category, either with dedicated graphics or without.
    The methodology of the testing is similar to consoles, but gaming is not required for devices that cannot run the game well. For devices that lack a dedicated graphics card, we have prepared a video to play. We have also prepared an HDR recording for devices that support it to check Spectrum’s stability when displaying HDR content.

  3. macOS devices
    Here we test Spectrum with devices that run macOS, then we have representatives from each model. For example, we have an Intel-based Mac mini, an Intel-based Macbook, Macbook with M1, and a Mac mini with M1.
    Gaming capability is fully excluded here, rather we focus on overall stability with viewing media content for an extended period of time with varying video modes.

  4. Mobile devices
    Included in this category are mostly cellphones. We have representatives from Android OS, iOS devices, and the long-gone but not forgotten, Windows Phone!
    Out of all other device categories, this category is the simplest to test because of the port and video mode limitations. The number of representing devices is also minuscule compared to other categories, but still important for Spectrum to be able to display input from these devices.

This concludes the update for this week on ES07D02. Thank you guys for reading and see you guys again soon! Please drop a comment below and tell us what you think :slight_smile:



I switched my orders from the 1440p glossy to the 4K glossy, but these are still interesting to read nonetheless. Very cool!


Ages ago I ordered a 1440p 240hz Spectrum. Is this it? Were all orders automatically switched over to this? Wonder when it will ship. Maybe in a few years?

Yeah this is for that model - they upgraded everyone to 280 Hz on it since they could. Last I heard shipping was towards the end of 2022, but we’ll see.

Yes as @ThomKlanc said, this is that model :slight_smile: Estimated shipping is for Q3 of 2022 and as we progress further in development we will keep you all updated!

Given shipping is currently taking at least 6 months at the moment, does that mean people will receive these, at the earliest, in Q2 2023, or do expect the shipping time to improve when these are released?

Does that mean the ES07D01 model is next? (QHD, 144Hz)

When can we expect it?

Hi there,

Yes, that is correct. ES07D01 will come after ES07D02.


Do we have a rough time estimate regarding its entrance to the mass production stage (ES07D01)? And how long did it take for ES07D02 to pass and tick all stages (past the Concept stage)?


I also noticed the company’s rebranding. Will this change the exterior design of Spectrum models in any way?


Hi @panos_kevop!

ES07D02 is currently still in development, with this topic being the latest update. Compatibility test takes a long time to complete - but things are moving forward.

Rough estimate for ES07D01 MP is sometime in Q4 2022.

It will not change the design of Spectrum models in any way.

Hey there,

“Q” as in quarter, correct? Expected around November?


Hi there,

Yes Q4 - the fourth quarter.

For those who preordered their ES07D02 Matte, are we stick with the original price (USD 749) or the new price (USD 949) listed in Dough website?

Furthermore, is the delivery date still targeting in Q3 2022 for new orders?

Hi there,

Yes, you will stick with the price during when the order was made.

Estimated shipping is still targeting Q3 for new orders.

What are all of the stages for the 280hz model? I see we were last updated that it is in PVT, is this the last stage, and then they are to be shipped out still within the Q3 estimation?

Hey @DingleDongle9

This topic is still the current status of the 280hz model! Yes, estimated shipping is still Q3 2022 :slight_smile:

Hey everyone! I chose Spectrum QHD 280Hz because I play singleplayer games in ultra settings like Cyberpunk and competitive FPS like Valorant so I can mix different types of games in one monitor. But I noticed that the Spectrum does not have a G-Sync module.

I decided to figure out what is the difference between G-Sync Compatible, G-Sync Module and G-Sync Ultimate. To make it easier for me to understand, I compared two Asus models: PG279QM and XG279AQM. In PG model is the G-Sync module, which means it has variable overdrive. What is variable overdrive means?

A dedicated G-SYNC module offers variable overdrive. Gaming monitors use overdrive to push their response time speed so that the pixels can change from one color to another fast enough to prevent ghosting/trailing behind fast-moving objects.

However, most monitors without G-Sync don’t have variable overdrive, but only fixed modes (for example): Off, Normal, Fast, etc. The problem here is that different refresh rates require different levels of overdrive. At 144Hz, the «Fast» overdrive mode might perfectly eliminate all trailing, but it also might be too aggressive if your FPS drops to ~60FPS/Hz, which will cause inverse ghosting or pixel overshoot.
For optimal performance in this case, you would need to manually change the overdrive mode according to your frame rate, which isn’t possible in video games where your frame rate fluctuates a lot.
G-Sync’s variable overdrive can change on the fly according to your refresh rate, thus removing ghosting at high frame rates and preventing pixel overshoot at lower frame rates.

Moreover, some G-Sync Compatible monitors have exceptional overdrive where one mode works perfectly well across the entire refresh rate range, but this is rare as well.

I have a few questions:

  1. How does the monitor work without G-Sync module, but with variable overdrive? For example, I often play Rust in 100-120 with drop to 60 FPS.
  2. One of the Eve developers said that if there is a G-Sync module will in the Spectrum, it will cost more. If you look at prices for QHD Fast IPS panels with 240-280Hz, I did not find a monitors more expensive than the Spectrum 280Hz wich without G-Sync module. So I want to understand why Spectrum is better than its competitors? For what I pay 750$ + 140$ shipping and waiting more than one year?

Sorry for my English, I from Ukraine.

G-Sync is just one of several technologies that allow for variable refresh rates (VRR). It was the first on the market and full G-Sync support requires buying a special chip and paint Nvidia a lot of money.

AMD released FreeSync a while later. It didn’t require a special chip and you don’t have to pay money to AMD to use it. Lots of monitors came out with only FreeSync support, no G-Sync, which was bad for Nvidia. They finally decided to support FreeSync but under the name “G-Sync Compatible”.

HDMI 2.1 also has its own version of VRR, which is slightly different to FreeSync. Not much used it until the PS5 finally enabled VRR super a few months ago.

The Spectrum supports both FreeSync and HDMI VRR, which means that VRR will also work with any Nvidia cards new enough to support “G-Sync Compatible” displays.

There are plenty of other monitors that can do some or most of what the Spectrum does. There are very few that do everything that the Spectrum does.

Does this model have use the same kind of Nano IPS is the 4k model’s? I would like to know if this will be an approved Blur Busters monitor or will be denied due to a long lasting red phosphor like the previous monitors.
