試下在机頂盒去Ｍ前加個１出２HDMI加強吓

HDMI 1出2需用電果種

Full HD ready usually means it is not true HD, ie, 1080P, so if that is the case, extra processing is needed by your 機頂盒, which might give you that problem, can you set your 機頂盒 back to 720P and let your AV amp do the upsampling?

Might be useful what sort of setting is available on your 機頂盒.

其實雞頂盒... MTV 之外, 全部行1080i / 50Hz 係最好最靚 !!!
舊既 TV 好似我以前部三星扒屎媽 (最多支援720P / 1080i ) , 用720P 會好過1080i 因為行P無行i 咁震 !!!
所以信自己對眼好過數據 !!! 行到邊樣靚就行邊樣咁就得了 !!!

我係機頂盒set720p 50hz已經有d窒，要set576先ok,想問下我如果set左576再去m係咪自動倍線1080p出去我部投影度架，如果係我就吾使理係機頂盒set幾低！我係用topcon>marantz sr7005>hc4000 70吋幕，同埋係米闗於放得越大尺吋就雖要越強嘅電視信號呢?

你意思係"機頂盒set720p 50hz去投影有d窒，而機頂盒set576去m倍線到1080p就無問題?

你部AMP有冇開增線? 會唔會因為Topcon已經有增線, amp再增線所以窒?
TVB source 應該得1080i....

Sorry I don't quite understand but by downsampling 1080i signal (HD TVB) back to 576 is something that you should avoid doing at all cost, regardless of what sort of video processing you have after your Topcon.  Processing of HD signal is I would say the less the better.

Is there some sort of Auto setting on your Topcon?  Can you try another set top box? Can you try a shorter and direct connection between your Topcon and your projector to see if I assume the longer HDMI cable is giving you problem, or the equipment in between?  Try isolating your problem one by one.

Sorry if I misunderstood your issue.

For short run, I think anything would do. Hope you find the solution.
