It shouldn't surprise you that I spend a lot of time in front of a screen. Whether it's for my business or my writing, my days tend to run long. A few years ago, I invested in a large 43-inch monitor to maximize the screen real estate. But as large as it is, you can only fit so much on a desk. Plus, it didn't help that the monitor was locked to 60Hz. I wanted something with the sharpness of a 4K screen, the smoothness of a high refresh-rate panel, and the ability to go a bit higher for games and movies when I felt like it. A projector seemed like a good fit, except that until very recently, such a projector didn't really exist. Not within a reasonable budget anyway. However, Texas Instruments recently introduced its DLP472TP chip, which has allowed a range of manufacturers to release 4K/120Hz projectors at less-than-nosebleed prices. I decided to try the JMGO Iris Ultra Max. This 4K projector supports 120Hz output, turning any wall into a screen larger than any monitor has any right to be, but it's the other bells and whistles that convinced me it's the one. A projector gives you much more flexibility than a conventional monitor. The motorized gimbal makes switching from work to play effortless. The problem with a conventional monitor is that it effectively becomes the centerpiece of your desk setup. You've got a fixed viewing distance and need to attach a monitor arm or VESA mount, too. I multitask a lot, and my desktop tends to be a clutter of windows, but there's only so big I can go with a monitor. The JMGO Iris Ultra Max, but for that matter, any projector, lets you scale up and down the screen size depending on what you're doing. What stood out to me about this projector is its optical zoom function. Got a small desk? You can scale down to a smaller, just-as-sharp screen. Need to turn that same projector into a gaming machine? Use the optical zoom to adjust the screen size. I've gone as large as a 120-inch screen, and the results have been tack-sharp. Even before XDA Developers get to picture quality and the other specs that made me choose this model, one feature stood out. It's got a built-in motorized gimbal. That means when I'm done with work, I can flip it around and project a massive display on the wall behind me to catch up on Netflix. In fact, the projector can even remember the exact horizon adjustments you made for specific areas. It literally takes seconds to switch spots, making for a brilliant quality-of-life addition. 4K resolution and 120Hz make the projector a viable monitor replacement. The dual iris system helps improve contrast. Of course, size was just one reason I was keen to switch to this model as a monitor. The resolution matters a lot. Given the sheer number of high-density text documents I tend to have on my screen, a 4K setup was a non-negotiable for me. Just as important was brightness. My work setup sits right by a large window, so I need something that can deliver a usable image in ambient light. Rated at 6500 lumens, the Iris Ultra Max should be more than capable on paper. Realistically, it is, with a small caveat. I found that the rated peak brightness applies only under specific settings, like a pure white screen. The actual brightness is noticeably lower, but not enough to be an issue. If you're using a projector as a monitor, keep in mind that ambient light will affect perceived contrast, and you'll just have to get used to it. That said, let's talk 120Hz, because it's one of the rarer features around. The projector also has HDMI 2.1 and variable refresh rate support, plus automatic low-latency features. I paired the projector with my MacBook Pro and easily mirrored my laptop's screen at 120Hz. No surprises there. Part of the reason JMGO has been able to drive down the cost of a 4K, 120Hz projector is that it doesn't actually use a native 4K imaging chip. Instead, it uses a 1080p DLP chip and pairs it with pixel shifting to produce a 4K image. Dual display controllers and a high-speed actuator enable this. While pixel shifting isn't exactly new, it uses two of the aforementioned TI DLP chips to drive the imaging system fast enough to achieve 4K at 120Hz. It's also why the image looks sharp, practically the same as native 4K versus the softer visuals you'd expect from an interpolated or upscaled image. There's a lot to like here, including built-in Google TV support, which lets me turn the projector into an entertainment system whenever I want. But what stands out most to me is the native contrast ratio achieved via a dual-iris arrangement. This is genuinely cool, as it lets me improve contrast levels in a room with ambient light by physically adjusting the projector's iris. While the projector works best with an ALR screen to eke out the best possible image quality, I can't fit one in my study. That's where the Iris adjustment has been useful, as I can extract better contrast even when running the projector on a blank white wall. A more flexible way to work. For now, I've been using the projector straight up on my wall, blowing up a 120Hz screen with my MacBook. Whether I'm writing or editing video, it's been a wonderful experience. Look, this isn't a replacement for hardcore monitor nerds or even gamers. Casual gamers and entertainment enthusiasts will find the JMGO Ultra Max more than satisfactory, and it does a fantastic job even if all you're looking for is a way to maximize screen real estate. It isn't perfect, and brightness levels aren't quite what the marketing claims, but that's a problem that plagues practically every projector on the market. What completes the package is what the projector offers beyond that. Whether it's the sharpness of 4K resolution, genuine 120Hz support, or the ability to turn it into an entertainment center on a dime, these are what make it interesting. For my setup, that's a big plus since I'm not just getting a bigger screen for work, but also the ability to turn it into an entertainment center once I'm done. It's a pricey upgrade over my old monitor, but I can't say anyone would regret making it. JMGO Iris Ultra Max. The JMGO Iris Ultra Max is a 4k / 120Hz capable projector with a rated brightness output of 6500 lumens.

TI unveils 3-GSPS ADC for AI Data Centers at OCP. OCP demonstrations include TI's new 3-GSPS ADC, 800-V hot-swap controller, and BAW oscillator for AI infrastructure. Texas Instruments Inc. (TI) has claimed the industry's first analog-to-digital converter (ADC) to enable 24/7 event-based remote monitoring at nanosecond resolution for AI data centers. Introduced at the Open Compute Project (OCP) Global Summit, TI will demo the ADC34DSO75 ADC, along with the new LMI800PS hot-swap controller and LMK6B bulk acoustic wave (BAW)-based oscillator, addressing the challenges of scaling AI infrastructures. Partner Content Enabling real-time nanosecond-level telemetry, TI claims the ADC34DSO75 is the industry's highest performance 3 gigasamples per second (GSPS) ADC, detecting transient power-rail glitches thousands of times faster than current solutions, minimizing downtime in AI data centers. The ADC detects and captures transient fault events in real time thanks to the combination of the ultra-high-speed sampling with advanced on-chip digital signal processing in a flip-chip chip-scale package (FCCSP), measuring 13.8 x 13.8 mm. The ADC offers hyperscalers "unmatched remote diagnostic capabilities at a fraction of the size and cost of conventional monitoring methods," TI said. TI also introduced the LMI800PS, claiming the industry's first 800-V isolated hot-swap controller. It supports both +/-400-V and 800-V distributions to provide a scalable solution for diverse rack architectures. This highly integrated device can replace a discrete solution that requires five ICs. Delivering in-rush current and power path protection in a high-density package, the device integrates an isolated bias supply and PMBus telemetry, which reduces board area by more than 60% and simplifies high-voltage designs. Enabling safe power insertion and fast fault isolation, the LMI800PS meets safety standards with 5-kVrms reinforced isolation and more than 8-mm creepage, preventing a single load failure from disrupting the shared power bus. Also unveiled at OCP is the LMK6B BAW-based oscillator. TI developed the oscillator with best-in-class jitter performance and power-supply rejection ratio (PSRR) to improve signal integrity in AI-driven networking. TI said the margin for timing error shrinks as data center transmission rates approach 3.25 Tbits/s. The BAW oscillator provides jitter performance of 9.6 fs at 625 MHz. Demonstrations will be on display in TI's booth, No. E45, at OCP. TI will also showcase its 800-VDC power solutions as part of Nvidia's MGX AI Factory Ecosystem wall, and TI's power electronics engineer David Reusch will present "800-V Data Center DC/DC Design Considerations, Topology Comparisons and Trade-Offs," on Oct. 15 at 2:45 p.m. in room 230A.

TI unveils ADC for nanosecond-level telemetry in AI data centers. October 13, 2026 At the Open Compute Project (OCP) Global Summit, Texas Instruments debuted the first analog-to-digital converter (ADC) to enable 24/7, low-power, event-based remote monitoring at nanosecond resolution. As AI workloads rapidly increase, data center operators face significant challenges around power instability, inadequate real-time monitoring and signal degradation, all of which can lead to costly downtime. TI is addressing these challenges through its new ADC device and other analog solutions designed to tackle the challenges of scaling artificial intelligence (AI) infrastructures. Demonstrations on display in TI's booth, No. E45, at OCP include: * Real-time nanosecond-level telemetry: TI's ADC34DSO75 is the industry's highest performance 3 gigasamples per second (GSPS) ADC, enabling 24/7, low-power, event-based remote monitoring at nanosecond resolution - thousands of times faster than what current solutions offer. Existing monitoring solutions often fail to detect the nanosecond-level power-rail glitches that cause costly, unplanned downtime in data centers. By combining ultra-high-speed sampling with advanced on-chip digital signal processing in a small form factor, the ADC34DSO75 detects and captures transient fault events in real time. As the industry's first solution to offer fully remote, event-based telemetry, the device eliminates the need for on-site debugging and oscilloscopes. By providing continuous, high-resolution monitoring of low-voltage, high-current power rails, the ADC34DSO75 helps data centers minimize downtime - which can cost operators hundreds of thousands of dollars an hour - while optimizing grid power efficiency. This compact, efficient solution offers hyperscalers unmatched remote diagnostic capabilities at a fraction of the size and cost of conventional monitoring methods. * Reliable high-voltage power delivery: The LMI800PS is the industry's first 800V isolated hot-swap controller, replacing a complex discrete solution requiring five integrated circuits with a single high-density package that delivers in-rush current and power path protection. The integration of an isolated bias supply and PMBus telemetry reduces board area by more than 60% and simplifies high-voltage designs. The LMI800PS enables safe power insertion and fast fault isolation, meeting safety standards with 5kVrms reinforced isolation and more than 8mm creepage. This prevents a single load failure from disrupting the shared power bus and maximizes data center stability. Supporting both +/-400V and 800V distributions, the device provides a scalable solution for diverse rack architectures, accelerating the deployment of high-efficiency power systems required for next-generation AI infrastructures. * Ultra-low jitter signal integrity: The LMK6B is a bulk acoustic wave (BAW)-based oscillator that delivers best-in-class jitter performance and power-supply rejection ratio (PSRR). As data center transmission rates approach 3.2Tbps, the margin for timing error shrinks significantly, and even minute jitter can increase bit error rates and cause system instability. The LMK6B provides industry-leading jitter performance of 9.6fs at 625MHz, ensuring reliable performance and preserving signal integrity for next-generation, AI-driven networking infrastructures. "As AI workloads drive massive scale, the need for real-time visibility and architectural stability has never been greater," said Karthik Vasanth, vice president and general manager for TI's Data, Converters and Clocks business unit. "By delivering industry-leading solutions for high-speed telemetry, advanced power protection and precision timing, TI is enabling hyperscalers and operators to design the next generation of AI data centers with optimized performance and minimal downtime."
