I bought this new a while ago and have been using it until recently. The monitor size is: 35 cm wide 20 cm high 38 cm diagonally, so it seems to be about 15 inches. I looked it up and it seems to be an Aivn 14-inch digital high-definition LED TV, model TV-141LED. There are some peeling stickers and the remote control is peeling, but it works normally. However, the sticker has peeled off and I can't tell the manufacturer. The power cord is included, but one of the tip covers is peeled off. There may also be poor contact, so it might be better to replace it with a new one. Please check the photos. Small LCD TV, with remote control, VGA input compatible. - Model: LCD TV - Accessories: Remote control, power adapter, cable - Input terminals: VGA, composite (red, white, yellow) - Operation buttons: Channel, volume, input switching - Size: Small Thank you for looking.
