Thats the most beautiful gpu I have ever seen.

In a "global market", all of these products SHOULD BE available to anyone in the world! Too bad that market is not designed to promote anything but profit.

I use a 30' HDMI cable with both my 2070 and 4070ti.

Hmmm, sounds very plausible. After all, he lists his 2 PhDs on his profile!

Maybe us peasants with double MAs should also do that, and throw in the AAs as well!

Galax has implemented the Parade PS8419, a 12 Gbps HDMI 2.1 retimer

That's only 1/4 the bit rate of HDMI v2.1, and less than the bit rate of of v2.0 (18 Gbps). At those data rates, is there even any benefit from retimers?

Also, in general, does it even make sense to have a retimer right next to the source? Shouldn't the signal be pretty pristine and non-degraded at that point?

At what resolution & framerate?

Wow! Can you say anything about the cable you used?

According to this, there are some HDMI cables capable of 18 Gbps up to 50 feet, by way of a built-in boost/EQ chip:

HDMI Cable from Blue Jeans Cable

BTW, I recommend that seller. They're no-nonsense cable geeks. I've bought several cables from them, including even a custom-made job.

Also, the wikipedia page on HDMI has a convenient table for relating resolution + refresh rate to data rate:

HDMI - Wikipedia

en.wikipedia.org

According to that, you can do 4k @ 8bpp at up to 74 Hz at 18 Gbps signalling rate.

I think I ordered it from Monoprice.

Heck, I have a 50 foot Amazon Basics 18 Gbps HDMI cable that cost like $50. Admittedly I usually only run at 1080p/60 to my TV, but it seems to work fine at 4k/60 too.

So how much longer can the cable be?
