Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →If you’re looking for a 45-inch smart TV, start by measuring the space rather than shopping by the diagonal label. Compact TVs are commonly grouped at 40, 42, and 43 inches in the current recommendations reviewed here; an exact 45-inch option may be uncommon in those listings. Check the selected model’s exterior width, height, and stand depth before buying.
Why a 45-inch TV may be hard to find
TV size refers to the screen’s diagonal, not its width. Two sets in the same size class can also have different exterior dimensions because of their bezels and stands. The compact categories featured in current buying guides include 40-, 42-, and 43-inch TVs, so a 43-inch model may be the nearest practical option to consider—but only if its actual dimensions fit your room.

1. Confirm it fits your room
- Measure the usable width and height of the cabinet or wall area, plus the available depth if the TV will sit on furniture.
- Check the manufacturer’s dimensions for the set with and without its stand. Make sure the stand fits the furniture and leaves room for cables.
- If wall-mounting, check the exact model’s VESA pattern, weight, manual, and required clearance. A mount must be compatible with the particular TV, and the wall must safely support the installation.
2. Match the screen to the room
Compare the screen technology available at your budget, along with contrast, brightness, reflection handling, and viewing angle. A bright room with windows can make reflection handling and brightness especially important; in a darker room, contrast may matter more. Check supported HDR formats as well, but do not assume that an HDR label alone predicts picture quality.

3. Check apps and software support
Look up the TV’s operating system and confirm that it offers the streaming apps you use in your country. App availability and software support can vary by region and model, so verify them for the precise local SKU rather than relying on a product name alone.
4. Match gaming features to your devices
If you play games, check the TV’s native refresh rate, variable-refresh support, HDMI input count, and the capabilities of those HDMI ports. Compare those specifications with your console or PC: extra gaming features only help when the source device and connection can use them.

5. Consider sound and the full purchase cost
Decide whether the built-in speakers are adequate for your room and listening habits. Add a soundbar only if you have a specific need, such as clearer dialogue or fuller sound. Before ordering, compare local price, warranty, return terms, delivery, stock, and available support—not just the listed TV price.
