LG UltraGear 27G61ZB-B: Specs, Price, Pros & Cons
This needs a disclosure more than a review, because LG sells the same hardware twice. Compared against the 27G610A-B we also cover, every specification row is identical — same panel, same brightness, same stand, same ports.
The differences are a certification badge, a different barcode, a lower list price, and which retailer stocks it. Two shelf tags, one monitor. Judged on its own it is among the strongest budget 27-inch gaming panels we have catalogued, with budget-grade extras to match.

Editor’s note
The 27G61ZB-B needs a disclosure more than a review, because LG sells this exact hardware twice. Comparing it against the 27G610A-B we already cover, every specification row is identical down to byte-identical dimensions and weights – same 200 Hz QHD IPS panel, same 400-nit brightness, same four-way stand, same ports. The differences: this ZB version carries no VESA DisplayHDR 400 certification (its marketing says 'HDR10' where the 610A says 'DisplayHDR 400'), it has a different UPC, a lower list price, and it is the SKU you will find at Amazon while the 610A lives at lg.com. Two shelf tags, one monitor.
Judged on its own, it is the strongest sub-$200 27-inch gaming panel we have catalogued. 200 Hz native with a genuine 1 ms GtG, 400 nits typical – unusually bright for budget IPS – 99% sRGB with factory calibration, and a stand that adjusts height, pivot, swivel and tilt at a price where tilt-only is the norm. Street pricing around $170-180 makes it something of a category benchmark.
The economies are visible if you look. HDMI is 2.0, so the full 200 Hz needs the DisplayPort. Contrast is a plain 1000:1, the panel is 8-bit, and the missing DisplayHDR certification means HDR content merely displays rather than impresses. There are no speakers and no USB. And unlike its own 32-inch sibling, it carries FreeSync Premium only – no NVIDIA G-Sync certification, though adaptive sync works fine on GeForce cards in practice.
Buy whichever of the twins is cheaper on the day – that is genuinely the whole decision. At equal prices, the 610A's DisplayHDR badge is the only tiebreaker, and it is a small one.

The bottom line
The LG UltraGear 27G61ZB-B earns a VS Score of 36, trailing most of the 91 monitors we compare here, at least on the spec sheet.
- Who it’s for
- Whoever finds it cheaper than its twin: 200 Hz QHD IPS, 400 nits, a genuine 1 ms GtG and a full 4-way stand, usually under $180.
- Who should look elsewhere
- Anyone who already owns the 27G610A-B – this is the identical monitor under an Amazon-channel SKU, differing only in its missing DisplayHDR badge.
- The trade-off that matters
- Benchmark-grade fundamentals with budget-grade extras: HDMI 2.0 only, 1000:1 contrast, no speakers, no USB, and FreeSync without G-Sync certification.
- The main alternative
- LG UltraGear 27G610A-B is the same hardware with a DisplayHDR 400 badge – buy whichever twin costs less on the day.
