I have Sapphire ati r9 270x graphic card and a samsung B2030 monitor display . My monitor does not have hdmi input and also it does not support full HD . Do i need to upgrade my monitor so that I can get full quality of display out of my graphic card ? Also i have an external TV Tuner card which is attached to Tata Sky HD TV setupbox . Even when i turn on the TV mode i dont get HD quality view of the TV on my display .
