hi any good switcher hdmi 5x1? i have one kinovo but im getting a less sharper image and darker in my case just like component one, i compare plugging directly hdmi cable to tv and with this switcher, but alsow i have one hdmi 5 in one out and signal its like one directly,
also if it can strip hdcp can be great. thank you.

Modern HDMI switchers not even participate in HDCP decryption like first generation of HDMI switches, they may only perform some limited equalization of digital signal to improve SNR and reduce jitter. So unless there is serious malfunction in your setup then you can't claim "less sharper and darker" image as it is against foundation of HDMI interface. It is only feasible if your HDMI resolution drop due issues with EDID so your source get or wrong or not at all EDID data and fall back to SD resolution.
I have a couple of low cost HDMI splitters that if the cables are not firmly inserted, show a picture with a heavy green cast, sometimes on one output, sometimes on two. The full detail of the picture is there, just with a green cast. I didn't think it was possible since digital is digital, but there's something happening that with the boxes.
well its 100% switcher its hdmi, and looks some darker and less sharper and if i connect directly to my tv looks better. also i get sharper image with couple splitters.

To describe this in different way - if i read about softened image and/or subtle tonal differences then it is like someone describing SATA HDD that store your files and everything is fine (folder structure, no errors on filesystem) however your excel or word documents have all capitals changed to lowercase...
Eye pattern looks like this and sane HDMI switch may improve digital data levels and apply re-clocking and some equalization to deal with long cables loss but it is unable to modify data especially in intelligent way (so keep image structure but alter sharpness) especially when data are HDCP protected (they are scrambled so video looks like colour RGB/YCbCr noise):
Another example of eye pattern diagram:
HDMI switcher see HDMI data only as series of 0 and 1 and it is able only to alter signal level and sometimes improve timing of those 0 and 1 - usually HDMI receivers are more tolerant than absolute minimum required by HDMI standard so that's why we may have 20 meters long HDMI cables even if standard specify only maximum 5 meter, better cable with better HDMI receiver will be able to work without problem but this is extreme case.
what i can say to you? i don't know about technical aspects, just with my eyes. and its clear that happen hdmi switcher its offering me less quality signal. sorry about that.
EDID miscommunication with some switchers? For example, on one TV I have a HDMI switch between a computer and the TV. If I turn on the computer before the TV I get a 1024x768 picture. If I turn on the TV before the computer I get 1920x1080. Different brightness may be RGB vs. YUV transmission and settings.
I saw badly designed HDMI on very reputable, large companies that are considered as high tech engineering leader. Everything is possible...
