Sceptre 27 inch 240Hz 1080p Gaming Monitor AMD FreeSync Premium HDMI DisplayPort, Height Adjustable Build-in Speakers Gunmetal Black (E275B-FWD240)

Ive had this for almost 6 months now, Ive never had a reason to change the input from hdmi3. Some how while pressing buttons, I changed it to displayport and I literally have no way of changing it back. Yes, I am pressing the volume buttons to scroll down the input options and I try to press the select button (M) and it seems to respond to me pressing it but it doesnt actually select the option, it says signal not found and then blacks out and when I check which input its on, it says displayport still... I literally cannot get it to change and I even bought an HDMI to DP and it doesnt detect anything when I plug that into my computer. This is highly upsetting and unacceptable, is my button defective or pressing E instead of M?

Best image quality for price, dont espect sound louder, so you can buy speakers. Highly recommended

Horrible quality too bright or too dark colors are ok, setting confusing and not a true 1ms response time.

My son loves the technical aspects

Everything is amazing but the sound
