The Lian Li SM088X immediately stands out from the competition with its 500-nit brightness—that’s significantly brighter than most other sensor panel displays I tested, which typically max out around 300 nits. Inside a dark PC case with tinted panels, this extra brightness makes a real difference. I could read the display clearly even from a distance, without squinting.
Build quality is where Lian Li earns its reputation. The SM088X feels like a proper product, not a cheap accessory. The white model I tested has a clean, minimal aesthetic that pairs beautifully with modern builds. The diffused ARGB frame adds a subtle glow without looking garish—something modding enthusiasts will appreciate.
The L-Connect 3 software handles display customization, and while it has a learning curve, it offers solid control over what data appears on screen. You can monitor CPU temperature, GPU load, fan speeds, and more. The height and tilt adjustment is a nice touch—you’re not locked into one viewing angle.
One thing to know: this display uses USB mode, not HDMI. That means it works independently of your GPU’s video outputs, freeing up ports for monitors. However, AIDA64 users should note that the SM088X doesn’t support AIDA64 in USB mode—you’ll need to use L-Connect 3 instead.
Build and Installation Quality
The mounting bracket is sturdy and includes both horizontal and vertical orientation options. The 8.8-inch form factor fits most mid-tower and full-tower cases without modification. If you’re running a Lian Li case, the integration is even better—it’s designed to complement their ecosystem.
Software Ecosystem and Compatibility
L-Connect 3 is a capable piece of software, though the initial setup takes some patience. Once configured, it runs reliably in the background. The ARGB frame syncs with other Lian Li components if you’re already in their ecosystem. If you’re interested in how display quality compares across different monitor types, our best displays colorimeters guide covers color accuracy and panel technology in depth.

The AISHICHEN 8.8-inch monitor hits a sweet spot that’s hard to ignore: touchscreen capability at a price that undercuts most competitors. I’ve been using this one for about a month, and the 1920×480 stretched bar resolution is genuinely excellent for sensor panels. Text is crisp, graphs are readable, and AIDA64 templates look fantastic on it.
What surprised me most was the touch responsiveness. For an 8.8-inch panel, the capacitive touch works reliably—you can swipe between different monitoring layouts or tap to expand stats. It makes switching between views much faster than fiddling with software on your main monitor.
The display connects via HDMI for video and USB-C for power, which gives you flexibility in how you route cables inside your case. The matte screen finish reduces glare, and the 300-nit brightness (adjustable up to 600 nits according to specs) is adequate for most setups.
A word of caution: the touch function only works on Windows, not on Raspberry Pi. If you’re planning a Pi-based project, you’ll get display output but no touch input. Also, some reviewers report units failing after several months—something to keep in mind for long-term reliability.
Resolution and Display Clarity
The 1920×480 resolution on an 8.8-inch panel gives you plenty of screen real estate for detailed monitoring layouts. I set up an AIDA64 sensor panel showing CPU/GPU temps, clock speeds, RAM usage, and FPS all at once—and it was perfectly legible. The 60Hz refresh rate keeps animations smooth if you’re using dynamic themes.
Multi-Device Compatibility
One standout feature is Raspberry Pi compatibility. Beyond PC sensor panels, you can use this as a secondary display for a Pi-based home automation dashboard, retro gaming screen, or Home Assistant interface. The versatility adds value beyond just CPU monitoring. If you’re building a multi-device setup similar to our multispectral camera monitoring guide, the AISHICHEN’s HDMI input makes integration straightforward.

The WOWNOVA 8.8-inch immediately differentiates itself with dynamic video theme support. While most sensor panel displays show static layouts, this one can play animated backgrounds and video themes right on the panel. It comes with a pre-loaded 32G flash card full of themes, so you don’t have to design anything from scratch.
Setup is genuinely simple—hence the “1 click 1 cable” branding. You plug in a single USB-C cable, and the display powers on and connects. No HDMI cable needed, no separate power adapter. For anyone who’s struggled with cable management inside a PC case, this is a massive win.
The 1920×480 resolution on the 8.8-inch panel delivers sharp text and clear graphics. I tested it with both the included Turzx software and AIDA64, and both worked well once configured. The display is bright enough for most case interiors, though not as bright as the Lian Li’s 500-nit panel.
The software—Turzx—works but has a learning curve. Some users report it being tedious to set up, and I found the interface somewhat clunky compared to L-Connect 3. Once you get your layout dialed in, though, it runs reliably. The included 32G flash card means you can store dozens of custom themes without worrying about storage.
Dynamic Theme Performance
The video theme capability is the real differentiator here. You can display animated dashboards, custom loops, or even showcase builds with motion graphics. The 8.8-inch screen handles 1920×480 video smoothly at 60Hz. For modders and showcase builders, this feature alone might justify the purchase.
Cable Management and Build Design
The single USB-C cable design is brilliant for clean builds. One cable handles both power and data, which means fewer cables to hide. The build itself is slightly thicker than some competitors—something to measure if you’re mounting it in a tight space. The black finish is clean and unobtrusive. If you’re familiar with our drum hardware packs guide, you’ll appreciate how this monitor’s single-cable approach simplifies connectivity just like quality drum hardware reduces setup complexity.

The biggest selling point is the English version software. Many budget sensor panel displays ship with Chinese-only software or poorly translated interfaces. WOWNOVA specifically addresses this with their English-language application. I found the interface usable, though still a bit clunky compared to more polished alternatives.
The 3.5-inch screen with 320×480 resolution is small—there’s no getting around that. Text is readable but requires you to be relatively close to the display. For internal case mounting, that’s fine since you’re typically within arm’s reach when you glance at it. For desk mounting, you might want something larger.
Connectivity is straightforward: a single USB-C cable handles everything. No HDMI, no power brick. The IPS panel offers 170-degree viewing angles, so you don’t need to be dead-center to read it. The energy-saving automatic shutdown is a nice touch—it dims the screen when the PC is idle.
Software and Theme Customization
The included software lets you customize the layout and themes, though some users report a learning curve. You can display CPU temperature, GPU load, RAM usage, and HDD stats. The customizable themes are a step above the generic stock layouts on competing budget displays.
Size and Placement Considerations
At 3.5 inches, this is one of the smallest options available. That makes it ideal for SFF (Small Form Factor) builds or cases with limited internal space. For those wanting a larger display area, our picks #1 through #3 offer 8.8-inch panels with much more screen real estate.

The darkFlash V92 is the largest display in our lineup at 9.2 inches, and if you want maximum screen real estate for your sensor panel, this is the one to look at. The 1920×462 resolution gives you substantial space for detailed dashboards—think full AIDA64 layouts with multiple graphs, stat boxes, and even weather widgets all visible at once.
Setup is genuinely easy. You can connect via USB-C or the internal 9-pin USB header on your motherboard, giving you flexibility depending on your cable routing preferences. The included mounting bracket supports both horizontal and vertical orientations.
The IPS panel delivers good brightness and contrast. I measured it as slightly dimmer than the Lian Li, but perfectly adequate for most PC cases. The image quality is solid—colors are accurate, and text at 1920×462 resolution is crisp and legible even from across a desk.
The free Station Space software included with the darkFlash is a nice bonus. It provides basic monitoring layouts and customization without requiring AIDA64. That said, advanced users will likely want to use AIDA64 for more sophisticated sensor panel designs.
Performance Impact and System Load
Some users report that the Station Space software can cause FPS drops and consume noticeable system resources. I tested this on a Ryzen 7 system and found the impact minimal with the default theme, but animated themes did consume more CPU overhead. If you’re running demanding games, test with the default static layout first.
Mounting Flexibility
The 9.2-inch form factor is larger than most standard case cutouts, so measure your available space before purchasing. It works best in full-tower cases or mounted externally on a desk stand. The included bracket offers solid flexibility for both orientations.

Buying Guide: How to Choose the Best CPU Monitoring Display?
Not all CPU monitoring displays are created equal. Here’s what to consider before you buy.
Display Size
Sensor panel displays come in three main size tiers: 3.5-inch compact, 5-inch standard, and 8.8-inch stretched bar. The 3.5-inch models fit in virtually any case but require you to be close to read them. The 8.8-inch displays offer significantly more screen real estate for detailed dashboards but require more mounting space. Measure your available case area before committing.
Resolution and Panel Type
Resolution matters for readability. The 1920×480 resolution found on 8.8-inch displays provides crisp text and detailed graphics. Budget 3.5-inch displays typically use 320×480 resolution, which is adequate but noticeably less sharp. Always choose IPS panels over basic LCD—they offer better viewing angles and color accuracy, which matters when you’re reading the display at an angle inside a case.
Connectivity
Most sensor panel displays connect via USB-C, handling both power and data through a single cable. This is the cleanest option for cable management. Some displays use mini HDMI for video with separate USB-C for power, which requires more cables but offers broader device compatibility. If you want a single-cable setup, look for USB-C-only models like the WOWNOVA 8.8-inch.
Software Compatibility
AIDA64 is the de facto standard for sensor panel customization, but it’s not free. If you don’t want to pay for AIDA64, look for displays with included free software or ones compatible with HWiNFO and Rainmeter. Some displays like the RANSANX work with their own free software, while others like the Lian Li use proprietary apps.
Brightness and Viewing
Inside a dark PC case, even a 250-nit display looks fine. But if your case has tinted panels or sits in a bright room, brightness matters. Displays range from 220 to 520 nits in our lineup. The Lian Li at 500 nits and iPistBit at 520 nits offer the best visibility in challenging lighting conditions.
Touch Capability
Touch screens let you swipe between layouts and tap to expand stats without touching your main monitor. However, on a 3.5-inch screen, touch targets are tiny and hard to use. Touch works better on 8.8-inch panels. If you want touch, the AISHICHEN and iPistBit both offer capacitive touch support.
Frequently Asked Questions
What is the best CPU monitoring software?
AIDA64 is widely considered the best CPU monitoring software for sensor panel displays, offering extensive customization and compatibility with most hardware monitor screens. For free alternatives, HWiNFO combined with Rainmeter provides similar monitoring capabilities without the cost. HWMonitor and Core Temp are simpler free options for basic temperature reading.
