ViewSonic OMNI VX2718-PC-MHD: problems, parts and running costs

Checked: 2026-10-31

Summary

A 27-inch 1080p curved gaming monitor with 165Hz via DisplayPort and 144Hz via HDMI. Owners report confusion over refresh rates, occasional need to adjust image settings, and accidental damage is not covered by warranty. Running costs are low at about $11.48 per year for electricity at typical use.

Common problems and fixes

Refresh rate mismatch between marketing and actual unit — Best Buy verified purchasers report the US product page advertises 200Hz and 180Hz, while the original manual documents 165Hz via DisplayPort and 144Hz via HDMI. Owners must confirm available modes on the exact unit using DisplayPort and OSD/EDID; do not force unsupported custom refresh rates. [1][2][4]
Poor default image settings — Some owners mention needing to adjust monitor settings to obtain a pleasing picture. The OSD includes ViewMode, color adjustment and response-time controls per the user guide. [2][5]
Accidental screen impact — A verified purchaser reported their child’s screen broke after being hit by a toy drone approximately two weeks into ownership. This is accidental damage and is not covered by the factory warranty. [5]

Parts and consumables

External power adapter + AC power cord — One set included. Original ViewSonic spare SKU and guaranteed OEM price: No reports found. Third-party compatible adapter for VX2718-PC-MHD is advertised at $17.99 with a one-year seller warranty; verify actual adapter output voltage, polarity, amperage and connector dimensions before buying. Replace only if damaged or faulty. [6]
HDMI cable — Not listed as included on current US official product box contents. HDMI 1.4 compatible cable is an optional store purchase if needed. No exact tested accessory SKU or cost established. Not a scheduled consumable. [1]

Yearly running cost

Mandatory fees, subscriptions and periodic parts: $0/year identified. Video display and local OSD do not require an online account or paid subscription. No periodic consumable replacement is specified.

Illustrative electricity: manufacturer lists 27W typical and 0.5W standby. At 8 active hours/day x 250 working days/year, consumption is 54 kWh/year, which is $10.80/year at an assumed $0.20/kWh. With the 17W Conserve preset, identical active hours use 34 kWh/$6.80, before standby. This is a calculation from manufacturer ratings, not measured owner-specific household consumption.

When it is a good buy

US advertised prices checked October 30, 2026: ViewSonic US direct lists VX2718-PC-MHD at $159.99, B&H Photo at $159.99, and Newegg at $159.99. Below $110 new with valid US factory warranty is excellent; $111–$130 is a strong budget deal. At $150–$160, the model is difficult to justify: ViewSonic currently lists 27-inch flat IPS 240Hz VX2726 at $159.99 and 27-inch QHD IPS 180Hz VX2728J-2K at $169.99, both manufacturer-direct in stock.

Alternatives:

ViewSonic VX2728J-2K (27-inch flat QHD IPS 180Hz, $169.99 manufacturer-direct) — Better for almost any mixed desktop/PC gaming user with enough GPU performance; it costs only about $10 more than the VX2718-PC-MHD. [9]
ViewSonic VX2726 (27-inch flat 1080p IPS 240Hz, $159.99 from ViewSonic US) — Better at same price for competitive 1080p gaming if motion performance matters more than VA black level and curve; the 240Hz rating is maker spec rather than an exact head-to-head measured motion guarantee. [10]
