Planning your LED screen connection
Start with your screen’s total pixel width and height, the source resolution, refresh rate and color depth. Then check how the load is distributed across the four output ports. A per-port pixel rating alone does not establish whether a particular screen layout and input timing will work.
Confirm the receiving-card model, cabinet configuration and cabling before replacing an existing sender. Share those details with us through the contact page if you need help checking the intended configuration. You can also browse our NovaStar products for related components.
Frequently asked questions
Can I configure the MCTRL660 without a computer?
Yes. The front-panel LCD and knob support quick screen configuration and manual brightness adjustment. Computer-free configuration refers to setup controls; a video source is still needed to supply the display content.
Does it accept both HDMI and DVI?
Yes. The MCTRL660 provides both HDMI and single-link DVI inputs. Match the source timing and color depth to the supported input mode listed above.
Does a 3840-pixel width mean full 4K input?
No. The documented wide custom mode is 3840 × 600 at 60 Hz. It should not be read as support for a full 3840 × 2160 input.
What should I check before buying a replacement?
Check the unit’s exact model, source connector, screen pixel dimensions, receiving cards and output-port layout. Do not assume similarly named controller models have identical features.
