CAT8 cable is now available
- Join Date

A roll of 1,000 feet of CAT6A cable which is rated for 10GB per second speed normal costs around $225-$300+ depending on the frequency needed. CAT7A cable that is rated at 10GB per second speed and which can do 40GB per second under short distances normal costs around $760 for 1,000 feet.
Now CAT8 cable is officially available (maybe CAT8A will become available soon also). Starlight CAT8 Ethernet cable that is rated for 40GB per second speed costs $210 for 1 meter length and $750 for 10 meter length. http://store.wireworldcable.com/collections/ethernet-cat8/products/starlight-cat8-ethernet-cable?variant=29742245836
Bulk shielded 1,000 feet CAT8 cable that is rated for only 10GB per second speed can be purchased for $780. http://certicable.com/cat-8-cables/1000-ft-cat8-cat-8-shielded-copper-cable-10gb-10-gigabit-ethernet-also-for-video.html
However, the official CAT8 standards have not been completed yet and final ratification is expected in early 2017. So some companies selling cable labeled as CAT8 with only 10GB speeds listed in the specs are most likely selling a cable design that is only slightly better than CAT7A. True CAT8 cable should do 40GB per second speeds.

LG OLED65E6P OLED Ultra HDTV Review

(Sound and Vision magazine review)
The Sound and Vision magazine review does not mention what refresh rate or frame rate that the LG OLED flat panel displays are using. In addition, the official LG spec sheet and manual fail to mention this information also. DLP projectors and plasma displays still have better motion quality when compared to OLED displays, and they also offer Cinema quality frame rates without frame interpolation and 3:2 pulldown issues. However, the black levels on 4K Ultra HD and 1080P OLED displays are absolute black, and outperform the best plasmas including the reference 2008 Pioneer PRO-141FD.
The LG OLED65E65P supports both HDR10 and Dolby Vision when it comes to streaming 4K Ultra HD programs using the built in apps on the Smart TV, however the HDMI inputs currently only support HDR10. On the LG OLED65E6P flat panel screen all 4 HDMI inputs use HDCP 2.2. However, according to the Sound and Vision magazine review these HDMI inputs are HDMI 2.0a, and if the review information is correct, then LG would need to issue a firmware update to the OLED65E65P to turn the HDMI inputs to version 2.0b so that Dolby Vision can be supported from an external device like a 4K Ultra HD Blu-ray player or external streaming device.
The following are select quotes from Tom J Norton’s review of the LG OLD65E6P
“The best LED-backlit local-dimming LCDs can now equal or exceed the performance of plasmas in what were their main calling cards: black level and shadow detail. But now, even LCDs have competition. OLED TVs arrived just about the same time that plasmas faded from the scene. So far, they’re offered only by LG, whose current models are much reduced in price from earlier designs—though they’re still not bargain-basement specials.”
“All of its HDMI inputs are HDMI 2.0a with HDCP 2.2…”
“Off-center viewing is comparable to what we experienced with plasmas: You can sit as far to the side as you like without seeing obvious image degradation. In that respect, this OLED set is far better than any LCD, even the best of them.”

The ideal future for projectors
- Join Date

One of the biggest negatives of projectors is the requirement to have a dark home theater room. Another negative is its more difficult to install a ceiling mounted projector since wires need to be ran in the ceiling and inside the wall back to the customers equipment. Some more expensive laser driven projectors have the advantage of no bulb changes and projectors are getting brighter so that they can offer HDR and do not need the room to be completely dark.
However the biggest advancement in projector technology is the laser driven models that are Ultra Short throw. No longer does one need to remodel a room for a ceiling mounted projector. Consumers can just remove the flat panel screen from their existing TV stand, and place a Ultra Short throw projector in its place. Then one can install a retractable remote control screen that is 140 inches or larger. This Ultra Short Throw technology has the potential of making projectors popular again with consumers. In addition if this technology becomes available for under $10,000 in the years to come, projectors will start eating into OLED flat panel screen sales. Just imagine if someone were to make a DLP Short Throw projector that is under $10,000 and offers 100-140 inch projected screen size. DLP is the king of motion and 3-D picture quality (far better then OLED displays in those two areas).
My existing home theater room when remodeling was wired for a ceiling mounted projector, but my bedroom is not wired for a projector. With a Ultra Short throw projector I could add a projector to my bedroom without needing to remodel my bedroom. Now that would be awesome.
