4K Tiled Displays Become An Issue With X.Org

[TheLexMachine]

I read that this is because the controllers of the monitor can't handle it as a single one. Maybe a cost related choice but i have no idea TBH.

Indeed. A single 4K feed requires HBR2 (High Bit-Rate 2) mode controllers, which haven't been implemented in monitors yet though the latest GPUs with DisplayPort1.2 all have it. By the time they do implement it, DP1.3 will be around which will have HBR3 and support higher resolutions/bitrates and HDMI 2.0 will have cornered the market for 4K PC displays.

And one does not exclude another. Look at .asound under ALSA.

The X equivalent for per-user configs is running xrandr commands in your .xinitrc startup file. Which is stupid as hell because it increases startup time, when the info could just be in a config file, but hey, it exists.

True

3D tv!
YES!
Consumers said no.

I know you're trolling, but it's true. Blu-Ray uptake has slowed also, DVDs are actually outselling Blu-Ray 3 to 1 as most consumers say they "Don't see a difference". I personally do see a difference but Blu-Ray has too many issues for me; like strict DRM, slow loading times, Firmware updates and the general horrendous and unreliable quality of the players. After 3 Blu-Ray players I bought a dedicated Upscaling DVD player and was quite impressed. It's not quite HD but good enough. My HD Satellite fills in for the rest of my TV viewing.

Blu-Ray just wasn't the jump that we experienced with VHS vs DVD. The 3D fad faded and while 4K is here, the hardware is badly designed and Graphic cards are hardly ready to handle that level of Gaming. It actually seems as if the manufacturers are intentionally driving consumers away from the "Boob Tube".

Yes

Oh oh oh, you want user defined configs. Sorry I thought you just meant like you could override what the hardware said via a config file

And one does not exclude another. Look at .asound under ALSA.

Xorg.conf can only be, by default, modified as root. .asoundrc can be modified as user.

What I meant

They did. Xorg.conf. God help you if you ever have to add more than a few lines to it because you're definitely in uncharted territory at that point

Are there so many 4K display users (on Linux) that this really needs to be an issue?

I saw a 39" 4K monitor for $500. It does 30Hz 4k and 120Hz 1080p over HDMI. I expect a lot of dual monitor setups are going to be replaced at those prices.

*chuckle* X hasn't changed much in the last 4 years since I moved out of AMD.

Federated configuration (X.org) helps, but then you have the user based (.config) and driver (amdpcsdb) specific configuration. It's hell...

The issue is differentiation. You can either wait for the standard and move en-masse, or you can push forward with a differentiator and deal with the issues... Back in approx 2006 there were two pushing the limits of DVI... Apple's Cinema display would "prefer" low res by the standard, but could do 2560 which was obviously what the user preferred. The other one was the IBM T221 (IIRC) which was dual channel - two connectors, one pane of glass. As they came out they had to partner with the graphics and operating system vendors to get hacks put in place in the presence of these monitors.

Realistically, if the path forward is smooth, everyone would be doing it. If you aren't pushing against limits, you aren't pushing hard enough to be calling your self hi-tech or innovative. Unfortunately some markets drag helpless users along too... And Linux is dragged further under foot .

You are obviously not familiar with ALSA :P

In fact, i dont see why they cant create something like .asoundrc but for Xorg...
But it's probably my ignorance.
