To all those who have external monitors. Im thinking about investing in a 20" LCD HD. Would love to get an apple one but i would prefer one that has a tv tuner aswell. The only one i could find is the Samsung T200HD http://www.samsung.com/uk/consumer/detail/detail.do?group=itbusiness&type=monitors&subtype=lcd&model_cd=LS20TDDSUV/EN My questions are; is 20" a good size? and secondly is there a way to get a mac 20" screen but have a good tuner on iit? Cause these tv tuners that they offer are total crap!!
