MAG 524: fixing a blank or stretched picture via HDMI settings
The most common stumble after connecting a MAG 524 for the first time is a resolution mismatch: the box sends a signal the television simply cannot handle, and the result is either a completely black screen or a picture that looks pulled out of shape. It happens because the box's default output does not always match what a particular TV expects on that specific HDMI input. Even viewers who have used a MAG box before can run into this when moving the box to a different room or plugging it into a different television. Every one of these problems can be fixed through the box's own settings menu — no engineer visit, no extra hardware.
Quick answers
- The screen is still black after I changed the resolution — what now?
If the screen is black and you cannot see the menu, press and hold the power button on the remote until the box resets its output to a lower resolution. Once a picture appears, go back into the HDMI settings and choose a value you know your television supports — 1080p at 50 Hz works on most sets. Also make sure the HDMI cable is seated firmly at both ends and that you have selected the correct input on the TV.
- Can a faulty HDMI cable cause picture problems?
Yes. A damaged or outdated cable can carry the signal unreliably, showing up as flickering, colour errors or an intermittent loss of picture. If you suspect the cable, replace it; for resolutions above 1080p use a cable that is explicitly rated for the speed that resolution requires.
- Do I need to re-enter the portal address every time I turn the box off?
No. The portal address is stored in the box and is not cleared by switching it off. You would only need to enter it again if the provider changes it or if you have reset the box to its factory defaults.
- Everything looks fine except one channel, which appears stretched — why?
When all your settings are correct but the distortion only affects a single channel, the issue is in how that channel's signal is being broadcast. There is nothing to adjust on the box or the TV; the problem is at the source.
Why does the screen go blank straight after connecting?
When the MAG 524 outputs a high-resolution signal — say 2160p, or 1080p at 60 Hz — and the television only handles certain refresh rates or does not recognise that format at all, the screen will stay black or display a 'no signal' message. The box and the TV need to agree on a signal format during what is often called the HDMI handshake, and that negotiation can fail, particularly with older televisions or cheaper cables.
The quickest first check is the cable itself. Try a different HDMI cable if you have one to hand; older cables not built for high-resolution output can drop part of the signal or carry it unreliably. If swapping cables makes no difference, the resolution setting is almost certainly the culprit.
If the screen is completely black and you cannot get into the menu at all, there is a way round it. With the box powered on, press and hold the power button on the remote until the box responds — on most MAG devices this forces the output back to a lower resolution that virtually any screen can display. Once a picture appears, you can go into the settings calmly and choose the right resolution.
It is also worth checking which HDMI port on the TV the box is plugged into. Some televisions have ports with different maximum resolutions — the socket labelled HDMI 2 might support 4K while HDMI 1 is limited to 1080p. Check your television's specifications before adjusting anything on the box.
Where to change the resolution in the box's settings
Go to System → Settings → HDMI (the exact label may read 'Video Output' depending on the firmware version). You will see a list of available resolutions: 576p, 720p, 1080i, 1080p, and on newer firmware builds, 2160p (4K).
The general rule is to choose the highest resolution your television reliably supports and that the HDMI cable can carry without loss. For most living-room televisions that is 1080p at 50 Hz. If you have a newer 4K set and a cable that can handle it, 2160p is a reasonable choice — but if the picture flickers or disappears again, drop back to 1080p; it is the value that works with the widest range of TV and cable combinations.
After saving the change the box will briefly restart and show the new picture. At that point check two things: whether the image is sharp, and whether the proportions look correct. Faces on screen should look natural, neither stretched tall nor squashed wide. If the proportions are off, that is a separate issue with its own fix — covered in the next section.
If you are unsure what your television supports, set the resolution temporarily to 720p. It passes on practically every screen, produces a decent picture, and gives you time to look up the TV's specifications before moving to a higher value.
For households that also run an Apple TV alongside the MAG box, the guide to handling the move from cable with IBO Player covers a different device but the same underlying logic around signal settings.
Stretched or cropped picture: sorting out the aspect ratio
A black screen and a distorted picture are two distinct problems with two distinct fixes. If the content looks stretched horizontally — faces too wide, or the edges of the frame cut off — the cause is usually a mismatch between the format the box is sending and the way the TV is interpreting it.
Start on the television side. Look for a menu labelled 'Aspect Ratio', 'Picture Size' or 'Screen Format' — it is usually reachable by pressing the Settings or Menu button on the TV remote — and set it to 16:9 or Auto. Options such as 'Zoom', 'Wide', 'Panorama' or 'Full' (without further qualification) all distort the proportions of an external source.
On the box side, in the same HDMI menu where you set the resolution, check whether there is an aspect ratio option. If there is, set it to Auto or 16:9. Aligning both settings — the correct format on the box and the right aspect ratio on the TV — resolves the great majority of distortion problems.
There is a third cause that often goes unmentioned: some televisions apply their own picture-enhancement modes automatically, such as 'Auto Wide' or 'Smart View', which silently alter the proportions of whatever is being displayed. Look for those options in the TV's picture menu and switch them off.
If one particular channel still looks wrong while every other channel is fine, the problem lies in the signal that channel is broadcasting. Your box and TV settings are not at fault in that case.
The portal and MAC address: what you need before you start
Setting up the portal on a MAG 524 does not involve installing anything — that is one of the defining features of this device-and-access pairing. All you need is the portal address and the box's MAC address. The MAC address is printed on a label on the underside of the unit; it is the unique identifier the system uses to recognise your box. Enter it alongside the portal address in System → Settings → Portal and the setup is complete.
Your access details, including the portal address, arrive at the email address you used when signing up — typically shortly after the payment is confirmed. If nothing turns up in your inbox, check the spam folder before contacting support.
The stream itself travels over your home broadband connection; there is no aerial to fit and no separate operator contract to sign. Picture quality depends directly on how stable that connection is. If you notice the image breaking up into pixelated blocks, or a channel stalling mid-stream, check the Wi-Fi signal strength in the room where the box sits. A wired ethernet connection from the router to the box is the most reliable solution — Wi-Fi can be inconsistent in a flat where the router is in another room or behind a thick concrete wall.
