I am a basic user who recently shifted from a 19 inch to a new 24 inch monitor- Dell S2422H. The text and display is noticeably pixelated. Videos may be less noticeable but the images, web pages, text are noticeably pixelated. The new monitor is running at its native resolution of 1920x1080 with 60Hz. I had a Ryzen3 based CPU running on onboard graphics (Mobo: ASRock B450 Pro) and the new monitor is connected to a HDMI port. I tried installing the latest display drivers (Adrenaline) from the AMD site but did not help. Tried the scaling to 150 or 175 but did not help. Downsizing the resolution also did not help much.
Will adding a basic or mid range graphic card help solve this issue? I am not a serious gamer so high end graphic card is not at all required.
Any work arounds if not the graphic card way? Or am I stuck here?
Buying another large size monitor is not a solution for me for now as I had already invested in this new monitor plus my work space cannot accommodate monitor beyond 25 inches.
Thanks.
