Pictures lose significantly brilliance and sharpness when viewing from a LENOVO i7 PC with NVIDIA card vs when viewing directly from the camera Sony HX400V Both cases using HMDI. I have googled and tried different settings on the NVIDIA card, but did not get much better. Please I need some suggestions on what to try. I am already very confused. Thanks.
Try to use the recommended graphic settings for PC when viewing on your TV, or adjust the quality settings on the TV to best. There is no problem in HDMI cable you are using I guess, it's just the matter of compatibility when viewing pictures using TV from your PC.
