Indeed. I think cables are still often sold with these arguments inherited from the analog era where cable quality actually made difference (up to a point, even then you did not really need to pay a fortune for a high quality cable).I think the point is that purchasing any cable when you have a perfectly workable one is kinda pointless.
Unfortunately there is still a bit of a misapprehension that buying a better cable might improve the picture somehow. Indeed retailers and cable manufacturers make a fortune out of it. I consider this exploitative and feel it should be challenged at every opportunity. So long as the scale you are using is working, without fault, it’s giving you as good a picture as that connector allows.
I can't help myself giggling for advertisements in my favorite AV-magazine where there are still 1-2 full page ads selling overpriced cables for listening to streaming audio.
I say this once more, in case your current HDMI-cable allows you to select highest possible/supported resolution and color depth on your monitor and as long as image is displayed without black outs, drops or visible sparkles on in, you will get 0% improvement by getting a new cable, ZERO PERCENT!!!!
