METZ 55MNH7000Z has a 122.6 cm-wide cabinet; a 128 cm opening leaves 5.4 cm total before required clearance and access. A nominal 55-inch image spans about 31.6 degrees at a centred 215 cm seat and 24.1 degrees at 285 cm. Those calculations answer different questions: check support separately, then compare actual centre and offset seats with the window controlled. [S1]
Subtracting the 122.6 cm cabinet width from a clear 128 cm opening leaves 5.4 cm total, or 2.7 cm per side when centred. This does not establish required ventilation gaps, support or access. The 134.5 cm-wide 60MNH7000Z and 144.5 cm-wide 65MNH7000Z exceed the example opening numerically; eliminating them does not automatically approve the remaining installation. [S1]
For a separate 126 x 38 cm furniture top, cabinet-width difference is 3.4 cm total. Against the 85.7 x 26.4 cm base footprint, surface differences are 40.3 cm in width and 11.6 cm in depth. These are envelope differences, not prescribed front, rear or side clearances. Confirm complete support, load capacity, stability and instructions. Include the 78.3 cm with-base height and equipment access before accepting the arrangement. [S1]
The supplied diagonal is 139 cm / 55 inches. Read cabinet tuples as width x depth x height and the base footprint as width x depth. Use these manufacturer-stated figures for physical planning, not the idealised image width calculated below. With-base and without-base weights belong to different support questions. [S1]
Without-base depth does not include bracket, plugs or required clearance. A base footprint does not specify an approved minimum shelf, while listed weight does not certify the support. Each value has a limited planning role and cannot replace the actual product and installation instructions.

Compare two declared room arrangements rather than choosing by floor area. In Layout A, a centred eye is 215 cm from the screen plane. Keep that position and compare a window opposite the screen uncovered, then controlled. Use a dark programme as well as a bright scene. This separates incoming light from image scale; the blind changes the room condition, not the panel or diagonal.
In Layout B, the centred eye is 285 cm away and a regularly used offset chair remains part of the household. Compare main and side seats under the same window condition, then repeat with window control. Do not assign the centred angle to the side chair or predict its colour and contrast from geometry. Those need the actual television. If the chair is unsatisfactory, test seat or screen placement before assuming a larger size solves the problem.
Assume a flat nominal 55-inch 16:9 active image. Original arithmetic gives W = 55 x 2.54 x 16 / sqrt(337), approximately 121.8 cm wide and 68.5 cm high. These are idealised image dimensions, not measured METZ active-area figures. Cabinet width for installation remains 122.6 cm. Keep the two numbers attached to their different purposes.
For a centred eye at distance d from the screen plane, horizontal coverage is 2 x atan(W / (2d)). It is about 31.6 degrees at 215 cm and 24.1 degrees at 285 cm. Lairds supplies contextual width/angle guidance. [S2] The closer seat sees a larger apparent image without changing panel performance. Neither distance is a medical recommendation, compulsory standard or manufacturer-prescribed seat position.
Measure from the seated eyes to the screen plane, not from the sofa back to the wall. Mark the approximate image outline at the proposed height and sit normally. THX offers screen-centre alignment as contextual setup guidance, not METZ model validation. [S4] Try caption size, faces, score graphics and a familiar interface. Repeat from the least central regular seat instead of approving the whole room from one central position.
At 215 cm, decide whether the wider apparent image suits ordinary programmes as well as films. At 285 cm, check whether your usual captions and controls work for you. These are personal questions, not universal readability guarantees. An outline cannot reproduce reflections, black detail or side-angle appearance; use the actual television for those and include familiar compressed material, not just pristine demonstrations. VESA's separate evaluation conditions explain why size and resolution alone do not settle picture performance. [S3]
55MNH7000Z documents QD-MiniLED, 3840 x 2160, Google TV, WLAN and LAN. Three HDMI inputs have CEC on all three and ARC on HDMI1; two USB ports are documented. These facts can match an intended platform and source arrangement, without establishing a particular brightness, motion or game result. [S1]
Compatible ARC audio on HDMI1 leaves two HDMI source inputs. List devices that must stay connected, decide whether an external player is needed and confirm essential Italian-market applications for the exact setup. Mark router, sockets and cable routes on the same room plan. A practical candidate must support the household's ordinary equipment as well as fit the furniture. If a picture or source capability is essential, retain the exact model only after relevant evidence resolves it.
The 200 x 200 mm VESA spacing and 9.6 kg without-base weight help begin mounting planning. They do not establish bracket capacity, wall construction, fixings or screw length. Check exact product and bracket instructions, cable access and finished wall projection. The 8.1 cm cabinet depth is not the whole wall-mounted installation, and viewing angles do not supply an installation safety allowance. [S1]
Check delivery access and a clear preparation area. Do not infer a one-person handling instruction from listed weight or invent a crew requirement. Follow actual instructions or use a qualified installer where needed. Switching from furniture to wall support requires a fresh check; it cannot shrink the cabinet or automatically fix inaccessible connections.
Retain 55MNH7000Z when the documented configuration, complete support, clearance and access work, and the apparent image size suits the actual seats. Exclude an arrangement if an essential support or service condition remains unresolved. Shared family configuration does not prove identical performance across sizes; a larger diagonal is useful only if it also fits and improves a preference you notice.
Compare complete current quotations after the installation and layout checks, including necessary furniture, mounting and external equipment. Confirm exact seller, availability, delivery and after-sales terms. METZ figures come from manufacturer documents [S1]; seating arithmetic is original under declared assumptions [S2], while external evaluation and setup guidance is not METZ performance testing. [S3] [S4]
Its 122.6 cm cabinet leaves 5.4 cm total before required clearance and access. This is a conditional width calculation, not approval for enclosure, support or ventilation. [S1]
With base: 122.6 x 26.4 x 78.3 cm. Without base: 122.6 x 8.1 x 71.8 cm, in width x depth x height order. Base footprint: 85.7 x 26.4 cm. [S1]
Weights are 9.8 kg with base and 9.6 kg without base. VESA is 200 x 200 mm. Wall, bracket, fixings, screw requirements and handling instructions remain separate. [S1]
No. The 31.6 and 24.1-degree examples assume a centred eye at 215 and 285 cm. Test the side seat separately, including actual reflections and off-centre picture appearance with window conditions controlled.
