How many Spectrum models are there?
Currently we have a total of 5 different Spectrum models, ranging from different resolutions and refresh rates. The monitors come with matte screen finish as default, however you can opt for glossy finish instead. Keep in mind that glossy panel option is only available on 4K model and QHD 280Hz model.
Are the glossy variants share the same model number as their matte counterpart?
Although they are very similar with only difference in panel finish, Spectrum glossies have their own model number. ES07DC9 is the model number for Spectrum 4K glossy, and ES07DCA is the model number for Spectrum 280Hz glossy.
This is important to keep in mind to distinguish the models apart for troubleshooting purposes and especially when choosing which firmware update package to use.
How do I update the firmware?
Spectrum features user-upgradable firmware. Updating the firmware may resolve issues and may improve or add new features. You can download the latest firmware updates from the Downloads section of our support page at
https://www.euro.dough.tech/pages/downloads.
Currently, the firmware update can only be performed on devices running Windows OS. Mac users may use Parallels to perform update.
Special instructions may be included, so keep an eye out for instructions.pdf included on each install package.
Remember that firmware update is a risky process. Please do not proceed if you are uncertain. We recommend only installing firmware update if you are experiencing issues or intend to use the new features it adds. Make sure that the monitor is connected to a reliable power source.
The new firmware doesn’t work well for me. Can I rollback?
You certainly can. Simply download the firmware package of the version you want to rollback to and proceed with installing as normal. Follow the installation instruction included within the firmware package.
My monitor refuses to turn on after running the update. Am I missing something?
If you have given ample time for the updater to process everything, then a prompt to restart the monitor will appear. However, there are a few instances when the monitor refuses to function properly after restart. When this happens, you will have to do a full power cycle (turn off the device and unplug the power cord for about 15-20 seconds) before turning on the device again.
You may have to perform the power cycle several times before the monitor functions normally.

I just got my Spectrum and I noticed that my firmware is currently on version 100. Does that mean I am using a legacy firmware?
That depends on what Spectrum model you have. Spectrums that came later in the development comes shipped with version 100 but already equipped with the latest features and bug fixes.
Always double check your model number with the firmware you install. Installing wrong firmware to the wrong model can cause issues to the monitor.
My Spectrum kept on blanking when used with my PS5
Implementation of PS5 VRR post Spectrum development caused the function to not being able to be tested properly before the units reach the hands of our customers. This caused the screen to not be able to process the image properly, which results in screen blanking and flickering.
To fix this, you will have to update your firmware to at least version 107 (for ES07D03 model). All other Spectrum variants are already shipped with the latest firmware available, which means that firmware update is unnecessary to fix this issue.
My Spectrum doesn’t perform as expected; some resolution options are not available and exhibits blanking/flickering.
There are a few things you can check; start with the cable used. Running a monitor with high resolution and high refresh rate requires a good cable. We always recommend using our Dough branded cables which has specifications to be able to facilitate the monitor’s maximum functions.
Another thing to check is your connected hardware. Make sure that the video card supports the resolution you are after. Always keep all drivers updated! Spectrum also has firmware updates which enables certain resolution options and bug fixes.
My Spectrum refuses to be detected as a FreeSync Premium Pro supported device. Is this an error?
In the OSD (On Screen Display), there is a setting which toggles AdaptiveSync option. This needs to be toggled on in order for your device to detect the feature.
