The Tools You Need and an Image You Can Rely On

The DM231 is a lightweight, power-efficient, wide-gamut, and color-accurate 23.8" professional monitor well suited to production, post production, and broadcast environments. The DM231 is a larger version of the 21.5" DM211 and pairs extremely well with it for multiple monitor environments.

Color Management

FSI’s 3rd generation Color Fidelity and LUT Interpolation Engine (CFE3) houses a multitude of calibration and Look LUT memories for highly accurate color reproduction and effective look management. Instantly select from Rec709, EBU, SMPTE-C, DCI P3, Rec2020 Emulation*, Native Wide Gamut, and Custom User Generated color spaces.

*Does not fully cover Rec2020 color space.

Additional gamma, peak luminance, and color temperature toggles further add to the versatility of DM Series Monitors.

DM series monitors support video range, extended range, and full range monitoring with simple menu based toggles.

CFE3 features industry leading tetrahedral LUT interpolation for greater accuracy and visual performance than hardware utilizing trilinear LUT interpolation.

Powerful DM series features are supported by select applications including FSI’s DM Series IP Remote Utility, Pomfort’s Livegrade Pro, QTake's Grade Module, and Assimilate Live Assist and Live Looks.


FSI monitors come pre-calibrated from the factory and all DM series monitors support highly accurate volumetric Auto Calibration for recalibration over time.

Simply plug a supported probe directly into the monitor and the advanced AutoCal routine will profile the monitor and use volumetric data to accurately target a very wide variety of available color management selections. 3D and 1D LUTs are calculated and saved on the fly as color management selections on the monitor are made, making for one simple and unified calibration process, all without requiring a computer.

Second Screen Output

Mirror what you see on screen to downstream equipment. Apply LUTs on DM Series monitors and other downstream monitors simultaneously.

Second screen outputs work in addition to standard loop through outputs allowing you to simultaneously output clean and manipulated images.

Note that you are always welcome to email info@dittools.eu or call (+372) 5556 0057 for a more accurate shipping time estimate, as this does vary depending on a number of factors.

Standard shipping

Unless otherwise noted, all items are shipped standard via DPD. We normally ship to European Union countries only – do contact us for possible exceptions, particularly other European mainland countries. Shipping times vary between 1 to 10 business days within Europe – an up to date estimate will be given at checkout.

Returning an item

If you are not completely satisfied with your purchase, you can return your item(s) for a full refund within 14 days of confirmed delivery.

Special sales, demo items and promotions may have modified return policies. If an item from a bundle is returned for refund, the total bundle discount or the total value of the gifts will get deducted from the returned item prior to issuing a refund. If the bundle discount (or gift value) exceeds the value of the returned item, the difference must be paid to be able to return the item.

Return autorization

If you would like to return any item(s), please contact us by either emailing info@dittools.eu or calling (+372) 5556 0057. We will share with you a Return Merchandise Authorization (RMA) code and ask that you clearly mark this code outside of your shipping box as you ship your item(s) back for a refund.

You will be liable for the shipping and any applicable customs/duty fees returning the item(s).

Incorrect items

If the return is made due to a faulty product, or an incorrectly shipped product, or if you are returning the item(s) due to a defect, or functionality issue, or because it is not the item you have ordered, we will gladly email or mail a return shipping label covering all shipping related expenses. In order to determine whether the return is initiated due to a technical problem, we may ask for you to provide visual support like images or a video on the item(s).


Returned merchandise must be in its original packaging, and placed in a decent shipping box, e.g. the same box that we shipped the items to you in. Please make sure to clearly mark the RMA code you have received from us outside on the box.

Do not forget to cover or peel off any existing shipping labels on the box.

DIT Supplies OÜ cannot be held accountable for return shipments that have not reached us or returns made without RMA codes. We strongly advise that if you are returning the item(s) with a carrier of your choice that you use a traceable shipping method.

It may take 4-5 business days for your return to reach us. Once it is received and inspected, your refund will be processed and automatically applied to your credit card or original method of payment within 14 business days. Please note that depending on your credit card company, it may take an additional 2-4 business days after your credit is applied for it to post to your account.

Customs, duties & taxes

There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
