Giant Mini RGB LG for couch gaming will cost CZK 30,990 after cashback. It supports up to 144 Hz

A racing circuit across a good portion of the living room has its charm. The LG 75MRGB86B6A combines a 75-inch screen with a fast panel, making it suitable for a gaming PC in addition to evening series. It currently costs CZK 35,990 on Alza. If you take advantage of the subsequent LG cashback, the final cost will drop to CZK 30,990. The size and gaming features are more interesting here than the flood of AI-related acronyms.

Quick summary:
✅ Makes sense for: Gaming and casual viewing on a really large screen, especially if you like LG’s controls.
⚠ Consider: Mini RGB evo is not the same as Micro RGB. A test of a related series points out limited local dimming.
💡 When ordering, you will pay CZK 35,990. A refund of CZK 5,000 requires purchase within the specified period, a published review, and registration.

A gaming PC doesn’t have to stop at a monitor

The panel operates natively at up to 120 Hz, and from a compatible PC, it can handle up to 144 Hz in 4K. It also adds VRR and AMD FreeSync Premium, which help adapt the refresh rate to the variable pace of the game. On the back are three HDMI 2.1 ports. When switching between a console, PC, and other devices, you don’t immediately have to figure out which cable to unplug.

The Magic Remote is also convenient: you aim the cursor with a hand movement and scroll through menus with a wheel. This might sound like a minor detail until you’re looking for a movie in the evening and don’t want to click through the entire menu. The webOS system includes Oneplay, Netflix, and other common streaming services.

Take the name Mini RGB with a grain of salt

LG builds on Tandem LED technology and boasts certified coverage of DCI-P3 and Adobe RGB color spaces. However, it explains that there are no independently controlled colored LED chips here as with Micro RGB. Therefore, the RGB label itself does not promise the same backlighting as in top-tier televisions.

This is consistent with the experience of Polish Wybierz.tv with the related MRGB85/86/87/88 family. The editorial team praises the gaming features, low latency, and convenient webOS but criticizes limited dimming and black levels in dark scenes. This is a test of a related model, not our measurement of this Czech variant. For an evening movie marathon, this is a more significant reservation than the number of AI features in the catalog.

Cashback doesn’t end with clicking “order”

For cashback, the TV must be purchased by November 15, 2026, and a review published on Alza. The application must be submitted no earlier than 14 days after purchase, and no later than December 13, 2026. Prepare your receipt, a photo of the product label, and a link and screenshot of the review. The money will arrive only after the application is approved. Therefore, in the cart, expect the full price, not the amount after cashback.

Do you use a large TV for PC gaming, or do you stick to a monitor?
