Quick rundown:

• Display: 7.4-inch touchscreen, 1280 x 800 resolution; some listings show OLED panels.
• Memory: 16GB RAM on the handheld models shown.
• Storage: built-in NVMe SSD options across listings (examples include 256GB, 512GB, 1TB and up to 2TB).
• Software: several items reference Steam OS 3.0 and handheld-focused ergonomics.

These highlights reflect the product listings on the page. For full spec details and exact model differences, check the specific product description before you buy and review availability at Walmart.

Display differences to expect:

• OLED models listed on the page use an OLED panel, while other listings reference LCD screens.
• OLED generally offers deeper blacks and higher contrast, which can make games look more vibrant; LCD models may have different brightness or color characteristics.
• Some product listings also note refresh-rate or panel specifics (for example, 90Hz on select models).

If display quality is important to you, compare the specific product descriptions and consider how battery life, price, and bundled accessories factor into your choice.

Ways to add or expand storage:

1. Choose a higher-capacity model at purchase — listings include larger SSD options up to 2TB.
2. Use removable media shown in some bundles (for example, SD card options) to store games and media.
3. Attach an external SSD or drive via a docking hub or USB adapter offered in the accessory listings to run or store additional games.

Keep in mind that available storage performance and fit vary by model and accessory. Check product pages for compatibility and consider Walmart's delivery or pickup options when getting additional storage hardware.

Common accessories shown on the page that help connect to bigger screens:

• Docking station or hub with HDMI output and power delivery — several listings mention 4K@60Hz output, Ethernet, and multiple USB ports.
• HDMI cable (often included with some hub bundles) and a compatible TV or monitor input.
• Optional USB peripherals like keyboards, mice, or controllers that plug into the hub for a desktop-style setup.

Different docks offer different video resolutions and charging capabilities, so review the accessory specs on the product page. Walmart carries a range of hubs and docks if you want to shop accessories and check local availability.

Protection and maintenance tips:

• Choose a protective case or silicone cover and a tempered glass screen film from the accessory listings to reduce scratches and improve grip.
• For routine cleaning, gently wipe the screen with a dry microfiber cloth; if needed, slightly dampen the cloth with water only and avoid spraying liquids directly on the device.
• Remove detachable covers before deeper cleaning and avoid abrasive cleaners or solvents that could damage finishes or films.

These steps can help keep your handheld in good condition, but follow any care instructions included with the specific accessories you buy. Check Walmart product pages for bundled protection options and return details.
