Review on Chengying Multi Touch Points Infrared Touch 27", Touchscreen, CYS-27-P10 by Robert Morales

I ordered a size 40. It's actually about 41'. It wasn't ideal for television. When I finally turned it on and plugged it in, the touchscreen lingered. I contacted their support team and they gave me a link to calibrate it with my Mac. There was no adjustment. Don't waste your money on this product. i give it back hope i get my money back
