I bought this new a while ago and have been using it until recently. The monitor size is: Width: 35 cm Height: 20 cm Diagonal: 38 cm, so it appears 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 wear on the remote, but it works normally. Please note that the manufacturer is unknown because the sticker has peeled off. The power cord is included, but one of the tip covers is missing. There may also be some contact issues, 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) - Control buttons: Channel, volume, input switching - Size: Small Thank you for looking.
