Heh, as it just so happens I have an Acer ET322QK, just got it in tonight. I keep reading places, including this post that it supports 1440p@75Hz... but unfortunately I cant for the life of me find out how to do it! If one of you know, please let me... xD Might not be possible to go 1440,60Hz. Look into it if its a factor. :/

I snagged up this Acer ET32QK monitor the other day and it finally arrived tonight. I've been messing around in the Nvidia control panel attempting to get her to 4K, 60Hz at 10bpc, and keep falling flat on my face... Originally, the stock DP cable it came with was having issues with the HDR setting on the monitor, and don't believe I managed to get a 10Bit signal at all with it. Assuming it was a bandwidth issue I decided to give one of my HDMI cables a go, and it worked! However there seems to be a few quirks, and I can't wrap my head around it. A) The color depth for YcBcR422 runs 4k at 60Hz at either, 8,10, or 12 bpc, but RGB appears to run at only either 8 or 12 bpc (at 30Hz....need a new cable I guess...) -Why dose the selection permit me to select either 12bit or 8bit, but not 10bit? Is this not an option? Am I missing something? Is not 12bit greater than 10bit? B) Would anyone be familiar to why the HDR profile on this monitor is greyed out while using DP at all? Seems rather odd...

Wow, that's cool, didn't know 18:9 was actually used.

Glad to hear it!

Ok, so the laptop goes from classroom to classroom? What operating system dose this laptop use?

Ok, so this is what happens? Day One Laptop 1 ---- Connected to ---- Display 1 Laptop 2 ---- Connected to ---- Display 2 Day Two Laptop 1 ---- Connected to ---- Display 2 Laptop 2 ---- Connected to ---- Display 1 What I'm trying to understand is if you're mixing displays each time with different laptops randomly, which is what I think you're saying. Then Windows may remember the display if you hooked them up to the same display each time. In other words, try pairing the same laptop and display a couple reboots. If it works then number your laptops and displays.

So you have 20 laptops and 20 BenQ rp704ks, all of which default to 30hz upon boot/connect? And what you want is to either make the changes made to the refresh rate to remain persistent or a batch file to auto set the refresh rate? Idk how to help with the batch file, but are you connecting the same laptop to the same display each time?

Is this a thing? Never heard of 18:9 before. I just don't see how professional work makes a difference. Maybe the pitch, but I doubt it. Sounds more like he wants something less intrusive on his desk, like a 4:3. But idk.

Motherboard LEDs Stated on the motherboard's specs, there are two RGB headers both supporting 12v by 3A, and one iaRGB header supporting 5v by 3a. It states for all three headers that it supports up to two meters. I don't feel like burning up my board lol, so I'm looking for input on my execution. I'm not sure if the LEDs listed above are 100% the exact same, but they should be in the ball park of what I have now, the listing from my order history was deleted. So what I did to get my numbers was start with the mobo - 12V(3A) = 36W Then the strip - 60W / 300LEDs = 0.2W 0.2W / 12V = 0.016667Aroughly 0.02A Then checked how many LEDs fit in that spec - 0.2W ( X ) = 36W | X=180 LEDs 0.016667A ( X ) = 3A | X=179.9964 LEDs ~or 0.02A ( X ) = 3A | X=150 LEDs Then the density of the LEDs - 300LEDs / 5Meters = ~60LEDs So according to the numbers I have roughly 12 watts per meter at full bright, and 60 LEDs in that meter, suggesting a total of 120 LEDs per header. So, am I to understand that the board can only push 12v up to 2m max? What If I have 80 LEDs on one side of the case and and the rest on the other, and ran an extension there to continue the stream. Would that count towards my 2m? I pretty much get that this is either a voltage drop scenario or perhaps related to load, but I'm not sure if that even matters because it would seem to me that the resistance of the wire is irrelevant at such small distances, especially at 12v to be a voltage drop issue, and the LEDs wouldn't necessarily draw more power the further away they were would they? I just want to make sure for the safety of the mobo, that the traces won't get stressed. I was thinking of powering the LEDs directly from the PSU, but isn't the voltage throughput what directly controls its overall brightness by passing through the R,G,B common rails? If there is a way to get RGB control form the motherboard, but power the strips separately, that'd be cool! And safe! :D I totally was going to do that for the iaRGB strip, but idk if the 80 led hard cap is due to software limitation or not... Thanks for reading my run on sentence, any help or input is highly appreciated!
