DIY 5k Monitor - success :-)

The glitching only seems to interact with QuickTime Player - there are no other screen effects, so I dunno.. Haijing Cool store have asked (on Aliexpress messages) that I send them a video of the problem, so we'll see...If the audio glitching affects the video then that sounds like the digital clock signal within the RTD2718Q main chip is malfunctioning when audio is being passed through, so not the amplifier chip circuit?
Beyond my expertise to diagnose...
Comrades, greetings to all. Last year, I assembled my monitor on the r1811, now I plan to assemble the same second one but on a cheaper controller. Is there any generalized table with the characteristics of different controllers and links to their purchase? I want to save as much as possible by having a second 5k monitor at hand.
Здравствуйте.
The cheapest are the 8-bit JRY-W9CUHD-AA1 and the newly released 10-bit JRY-W9RQUHD-FA1, and JRY-W9RQUHD-SA1, from Shenzhen JRY Xinxian Technology Co., Ltd.

I love the thorough effort to retain all functionality except the CPU. I don't know anything about 3D printing, but my library offers a printer for patron use. Could you share the shape file for your rear door replacement? It looks very tidy, as opposed to my wires all dangling out the back of the open cavity. Thx. -Dean
I have received the JRY-W9RQUHD-FA1 and have been using it for 5 days now with a 2019 27" 5k iMac (LM270QQ1 SD E1). After dialing in the color profile, the image is as good as if not better than when I was using the iMac normally. 5120x2880 60Hz 10-bit RGB using DisplayPort to DisplayPort. Also the same using HDMI to HDMI.
Also works with my M1 16" Macbook Pro! Make sure you get an 8K USB-C to DisplayPort cable, I was using a 4K USB-C to HDMI and having issues with achieving the native resolution. The seller on Taobao was helpful and let me know to change the cable. Some cable manufacturers cheap out on the USB-C/Thunderbolt side of the cable.
I also purchased a CY.R9513 V5 from here to convert my 21.5" 2017 iMac display to a second monitor. This came with a remote which was super useful, the JRY-W9RQUHD-FA1 does not have a remote. I can only manage 8-bit color but honestly I can't tell the difference. Also make sure you use a 12V DC power supply for the 21.5" driver board, not 24V like the 27" driver board!
Weird note: the 21.5" display gets noticeably brighter than the 27", but it's a non-issue for me.

Comrades, greetings to all. I recently ordered the cheapest fee from the link,
sl.aliexpress.ru
. I bought a broken matrix for testing, and as I expected, it turned out to be serviceable while I tested it in 4k resolution (on a work computer). I have already removed the broken glass to replace it with glass from imac 2010. Wish you good luck in the fight against oca glue. (Photos of the process, if anyone is interested) I used a blow dryer and a fly to remove displays of 0.10 millimeters and an hour of working time

Does not work with 12v, I used this 24V 8A power supply
interesting find! would love to experience 165Hz!To members who have compiled lists of the various boards used for DIY monitor conversions, like @i486dx2-66 and @sebko200, yet another pair of new boards seem to have appeared...
With similarities to the Haijing T18 and T19, and with the same prefix as the JRY-W9CUHD-AA1... we now have the
JRY-W9RQUHD-FA1, and the JRY-W9RQUHD-SA1, from Shenzhen JRY Xinxian Technology Co., Ltd.
There are pictures of each board under the Specifications>View More tab, and a description:
The JRY-W9RQUHD-FA1 board is a UHD display driver board
Built in MPRT dimming function, maximum resolution
5120X2880/60HZ
*supports eDP screen interface signal output.
*supports multiple OSD languages to choose from.
*supports HDMI 2.1, HDCP supports version 2.3.
*supports DP1.4 signal input.
*supports headphone and speaker functions.
*supports OD acceleration function.
*supports Freesync functionality
*supports HDR function.
The JRY-W9RQUHD-SA1 board is a QUHD display driver board
Built in MPRT dimming function, the most efficient
The high resolution is 5120X2880/165Hz.
*Support EDP screen interface signal output.
*Supports multiple OSD languages to choose from.
*Supports HDMI 2.1, HDCP supports version 2.3.
*Supports DP1.4 signal input.
*Supports USB mouse, keyboard, and other functions
*Supports headphone and speaker functions.
*Supports TYPE-C video input and provides external 90W power supply.
*Supports OD acceleration function.
*Supports Freesync functionality.
*Supports HDR functionality.
With typos/misleading differences in the listings and pics - The high resolution is 5120X2880/165Hz, and Both driver boards can achieve 5120X2880/165Hz. 10BIT, Supports HDMI2.1 etc, it remains to be seen what they actually can do.
The screenshot pic shows HDMI 5K RGB 10-bit using Windows, so presumably they are an advancement over the earlier boards?
No IR remote, however.
how does this compare to r1811 v4 upgrades and downgrades if any?
The R1811 v4 board, like all the boards (R9A18, T18. T19, JRY-W9*CUHD-AA1/FA1/SA1) using the RTD2718Q video chip all do 4K at 144Hz.
This the the primary reason that Realtek produced the RTD2718Q chip - to allow monitor manufacturers to produce budget 4K/144Hz monitors, like the Dell G3223Q.
With tweaking using nVidia Windows graphics drivers 4K refresh rates can be higher, ~165Hz.
No 5K panel is capable of more than 60Hz.
Connected to a Mac with an M2 Pro/Mac/Ultra or M3 Pro/Max CPU, then the maximum refresh rate is:
HDMI display video output

I've just noticed a further new board, the R1815 v2 has become available.
This is a development of the R1811 v4, capable of driving the LN270QQ1 and LM270QQ2 panels, but it’s primary purpose is to drive the panel from the 2017 Dell UltraSharp 32" 8K Monitor UP3218K, with the LM315QU1 8K panel.
This seems to require dual DP 1.4 inputs to get 8K, rather like the R9A18 did to get 5K 10-bit.
Price?
$748 haha.

Since the 8K panel is not really available yet, it seems a speculative development, but it does mean the R18** boards are getting development, which has to be a good thing.

"No 5K panel is capable of more than 60Hz." that's the news you don't want to hear... thanks for the great info again mate
Does anyone here have the dimensions of the rounded corners of the glass? It doesnt seem to be a perfect circle from my measurements
Edit: Turns out to be something called a Squircle, it's formula is y4+x4=R4
. I'll try to get some time on a CNC and make some guestimates on the radius. Thanks for the help guys, was driving me crazy!

It looks like the arc of a a circle to me, but with the slightest Bézier curve increase in the radius as it becomes straight.
The radius of the circle seems to be exactly 15mm (0.59 inches).
This is an estimate as I only have a circular £2 British coin - 28.45mm diameter, a fraction too small, and a Dremel cutting disc - 32mm diameter, a fraction too big, to hand.
The bezier effect is clearer when looking at the case:

Hi all,
I've been working on my conversion and I can't get it to work... I connected everything and the monitor keeps turning on and off.
I tried with original power source it came with, I bought another one recommended here with 6A I then tried with a bigger power source with 12.5A and still same issue.
I tried with and without the current booster and no change.
My Specs:
lcd: LM270QQ1-SDF1A2115
current booster: DZ-LP0818
driver: R1811 V.4
I attached the video showing the on and off switching. This is annoying, I've been debugging it for the last week with no success. Any help is welcome at this point 😣

@sec89, did you use the original Apple PSU with this, or did it come with a new one? If a new one, did it fit in the case or did you keep it external?
Also, does it charge the connected laptop via the single cable? I assume not as it would need a 24v supply.
@hiwdu8 Your video shows that the R1811 constantly restarting and reinitialising.
That is not typical of PSU low voltage cutouts, which just show momentary blackouts, but no reinitialising splash screen.
My guess is that this may be a problem with the Power On circuitry, or the Power On button on the Control Strip - pin 4 on the ribbon cable, counting top down on the connector on the R1811.
Have you made any modification to this circuitry, or is the Control Strip getting shorted to ground in any way?
If you have the ability you could try powering up the board with the Control Strip ribbon cable disconnected, and powering on the R1811 by momentarily connecting pin 3 and pin 4 counting top down on the connector.
If the problem persists, then the problem must be on the board.
EDIT:
Quote: "I tested the R1811 on my friend's LCD panel (LM270QQ1 SDA2) and it works great so I know that the driver should be fine."
I missed that you posted this earlier.
How did you do this test? Did you attach your friend's screen to your build in your iMac case, or was the test done with the bare board connected to the A2 screen?
Did you attach your 60 pin eDP video screen cable to your friends screen?
If everything that worked with your friend's A2 panel is exactly the same as your build, then maybe? the 60 pin video connector on your F1 panel is not correctly making contact - dust etc.

@kevinherring There is no USB-C port on the 4K R9513 board, which is what was being referred to. So no laptop charging....
Not a direct answer to your question, but it's an Apple thing, and it has a name — the squircle.
If you know what super-ellipses and differential geometry are, you'll be sweet.
Rounded Corners in the Apple Ecosystem
If you look closely, you’ll rarely find a sharp corner in any Apple product. From the HomePod, to keyboard buttons, to elements in Apple’s own apps, the shapes are so smoothly-rounded that it’s not apparent where the straight lines end and the rounding of the corners begin.

A Smooth Corner Radius in iOS
I remember looking at an Apple interface, comparing it to the things I was creating, and feeling a bit miffed that Apple’s designs were…
I‘m nearly done with my conversion and saw similar behavior on my R1811 board during testing when I connected it to my PC.
I was very worried about the power supply etc, but it turns out it was due to trying to run at 5K with a 4K-rated DP cable.
Have you tried swapping cables or connecting to a different computer?
I did not use the original Apple PSU, I bought a separate 24VDC which I linked earlier for the 27, and I already had a 12VDC laying around for the 21.5. Both models I purchased were 2xHDMI 2xDisplayPort for a total of 4 ports on each board. I did not purchase the USB-C models
