While I was disappointed is certain aspects of the Lume Pad 2’s hardware and software, one thing which was not lacking is the 3D effect technology itself. While it does have a few rough edges, it overall provides a much nicer view of 3D content than a boring 2D display. It is definitely something I would like to see in a standalone desktop monitor.
Leia does have a 4k 120hz MiniLED “Monitor 27” platform listed.
While it’s not clear if Leia itself or another manufacturer could end up releasing it, there are some things I would like to see and some things which are a must have for me in a potential 3D desktop monitor. What about you?
A reasonable price
The Lume Pad 2 has been discounted as low as $650. Cooler Master and Acer have 4k 160hz MiniLed monitors which have a regular cost of $800, but has been discounted as low as $600. It seems to me that around double the cost for going from 2D to 3D would be perfectly achievable.
- Low price (~$1000-1200)
- Moderate price (~$1200-1400)
- High price (~$1400-1600)
- Very high price (~$1600+)
Use cases
I would expect that the desired qualities of the monitor would vary significantly based on the use cases, whether someone is viewing 3D engineering models, 3D movies, or playing 3D games. Personally I would use 3D for gaming and movies, but stick to 2D for productivity.

- 3D entertainment, content consumption

Compatibility with existing 3D source devices and content
There are multiple types of 3D output devices which have been on the market for years. While it is possible to offer a proprietary SDK for modern computing devices like laptops and tablets, for many devices that isn’t possible. Prior generation game consoles like the PS3, PS4, Xbox 360 apparently have a fair selection, (about ~100?) of 3D games, and of course old games and consoles can’t take advantage of new SDKs. And I would assume that a significant portion of nonprofessional consumers who would want a 3D display would like to watch 3D Blurays on a Bluray player, which definitely won’t be updated to support a new SDK. As far as I understand there are several standardized ways to output 3D over HDMI and DisplayPort, hopefully they could all be supported.

Glossy vs matte panel type
I personally would love to see a glossy panel. I have a glossy phone and tablet, matte monitors, a glossy laptop and matte laptops, and I can tell a big difference in display quality, the matte displays just look dull, while the glossy displays look sharp and vibrant. Here is an example of a identical monitor with only the difference of glossy or matte panel.

USB C video/power/data ports
Fortunately seems to be the trend nowadays, being able to have a direct single cable connection to laptops, tablets, phones, and gaming handhelds without a separate dock is very nice. As to power output, 30w or so would be plenty for me personally.

USB Switch
My current monitor has a 2 way USB switch over either the USB C or DP/HDMI with USB B. This lets me connect my mouse and keyboard to the monitor’s hub, and then they automatically switch between my desktop or a laptop depending on which is being displayed, though I need to use an additional external USB switch if I want to assign to the other 2 video inputs. There is a least one monitor with a 4 way every video source USB switch. I would very much like to have at least a 2 way USB C or DP/HDMI USB switch built in to the monitor, ideally with a USB B connection alongside each DP/HDMI video connection to eliminate any need for an external USB switch.

All video ports capable of taking full advantage of the display resolution, refresh rate, color depth, 3D
This is a pet peeve of mine. Several modern monitors have been released with so called HDMI 2.1 ports with crippled levels of bandwidth requiring chroma subsampling to run at the full resolution and refresh rate, or with USB C video ports which support a limited refresh rate. Or TVs like Sony where 2 out of the 4 HDMI ports have modern features and full bandwidth and the other 2 are obsolete ports.

3D AI conversion
One of the touted features of the Lume Pad 2, the ability to convert 2D content to 3D in real time. Some people seem to really like the LP2 implementation, but I found it to be pretty poor quality, enough that I wouldn’t bother using it. The depth it produces is very shallow compared to natively rendered 3D content, and it totally goes haywire if any text such as burned in subtitles is present. However, I still think the idea has potential, I would simply like to see some major improvement in the implementation. I would assume on a monitor this could be done as a global conversion of the connected input sources, though of course doing it on the monitor would increase the required hardware and thus cost. It could be done with an SDK, but then locked down devices like game consoles would not be able to take advantage of it.

3D eye tracking
Eye tracking for 3D content on the Lume Pad 2 works mostly well, though it sometimes has some hiccups, possibly caused by my wearing glasses. The biggest problems are the limitation of requiring the environment to be lit, not working in the dark, and being limited to a single person.

OSD controllable by connected input devices
There are a few MSI monitors with the ability to control the OSD with wired game controllers. Controlling monitor OSDs with buttons or analog stick on the monitor is clunky. It would be cool to be able to press a single button on the monitor to open the OSD, and the monitor could then reassign input devices connected to the USB hub to control the OSD instead of forwarding them to the upstream devices, then switch them back when the OSD is closed.

Monitor control software, ideally cross platform
The OSD control stick on my MSI monitor malfunctioned within 2 months of use, so now I just use the provided Windows utility to change monitor settings instead of the native OSD. It would be nice to have such monitor control software. One way this could be implemented would be WebUSB, which could enable supporting 5 out of 6 of general computing OSes with a single application. Even better to also have a publicly documented API usable for third parties, and robust support for control using existing tools over DDC/CI, CEC, USB MCC.

Cross Platform or Open Source 3D SDK/API
I assume that custom communication between the monitor and source devices required for an SDK or API would have to take place over USB, thus it should be possible to provide an SDK for every platform which provides USB device access to applications. As I know that should be at least Windows, Linux, Mac, Android, Chrome, and Edge. It would be great to see all of these platforms officially supported, but I understand that Leia has limited development resources, so if not I would at least like to see it open enough to enable the community to support other platforms themself if anyone wished to.

Built in speakers
Some monitors have speakers built into the bottom or back, usually not the best quality, but good enough for basic use and convenient as they don’t require keeping track of another device.

USB audio output
I use USB C desktop speakers, USB C wired earbuds, and wireless headphones with a USB A dongle, so being able to output audio over USB is important to me. There are a lot of devices which support USB audio output, laptops, desktops, PS5, etc. However, there are a lot which don’t support it, like Wii, Xbox, disc players, etc. It is the reason why the only type of TV I would consider purchasing is Android TV, because it is the only smart TV platform which supports USB audio output. This enables relaying the audio output to USB by extracting it from the HDMI source connection, making otherwise incompatible audio source devices work with USB audio output devices.

Refresh rate
A lot of monitors such as LG’s just announced ThinkVision 3D are still limited to 60hz, which is pretty unimpressive. The extreme high refresh rates like 480hz are somewhat niche, useful for things like competitive gaming, but even for general use such as moving the cursor around the screen, having 120hz or higher looks much nicer than 60hz, and I would consider at least 120hz, ideally higher, a requirement for any display I purchase going forward.
- Must have 240hz+
- Must have 120hz+, nice to have 240hz+
- Nice to have 120hz+
- Fine with 60hz
Ethernet port and passthrough
An ethernet port could be included. Personally, I would not want this to be utilized directly by the monitor for smart display or update functionality because of the increased possibility for security vulnerabilities. It would however be useful to passthrough to connected HDMI devices without their own ports, such as Chromecasts, and connected USB C video source devices, laptops, gaming handhelds, tablets, etc.

Repurpose eye tracking module as generic USB camera
Since autostereoscopic 3D based on eye tracking would need to have a camera module built into the monitor, it would be great to be able to repurpose it to use also as a generic USB camera over the monitor’s USB hub for video calls with connected desktops or laptops. Also the inclusion of a microphone to complement the camera.
