Acer Nitro EDA340CUR J0: Specs, Price, Pros & Cons
The cheapest way into a 34-inch curved ultrawide from a name brand, and one correction belongs up front: despite what several retail listings claim, this is a VA panel, not IPS.
That is not a downgrade so much as a different trade — far deeper blacks than any IPS ultrawide near the price, in exchange for weaker viewing angles and dark-scene motion. What you are really buying is screen real estate, and at this price that is a good pitch.

Editor’s note
The EDA340CUR J0 is the cheapest way into a 34-inch curved ultrawide from a name brand, and one correction from our audit belongs up front: despite what the Amazon listing title says, this is a VA panel, not IPS. The spec databases for this exact part, the retailer listings, and the fact that Acer's entire ED0 series is VA all agree; the listing title is wrong. VA here is not a downgrade so much as a different trade – you get 3000:1 contrast and far deeper blacks than any IPS ultrawide near the price, and in exchange the viewing angles and dark-scene motion are weaker.
What you are buying is screen real estate: 3440×1440 across a 1500R curve at around 110 ppi, with FreeSync Premium and a three-year warranty. For productivity-plus-gaming on a budget, that is the pitch, and it is a good one.
The honest limitations: 120 Hz is the slowest tier of this chassis – Acer sells the same 34-inch curve as the X0 at 200 Hz and W0 at 240 Hz – so if refresh matters, know the ladder before buying the bottom rung. Brightness is 250 nits with decode-only HDR10. The stand only tilts. And this SKU is unusually bare: no speakers, no headphone jack, no USB of any kind. The two HDMI 2.1 ports are a small joke on a 120 Hz 1440p panel that will never use their bandwidth.
The 1 ms claim is Acer's VRB figure, not a GtG measurement – typical VA response is the real-world experience, and VA smear in dark games is the thing to test in the return window.
At its frequent street price near $250, I think the size-per-dollar carries it – as a first ultrawide for someone who mostly works and sometimes plays.

The bottom line
The Acer Nitro EDA340CUR J0 earns a VS Score of 29, trailing most of the 91 monitors we compare here, at least on the spec sheet.
- Who it’s for
- A first ultrawide on a real budget – 34 curved inches, 3000:1 VA contrast and a 3-year warranty for the price of an ordinary 27-inch.
- Who should look elsewhere
- Refresh-rate buyers: 120 Hz is the bottom rung of a chassis Acer also sells at 200 and 240 Hz. And anyone needing speakers, a headphone jack or any USB – this SKU has none.
- The trade-off that matters
- Maximum screen per dollar on a VA panel the listing mislabels as IPS – deep blacks in exchange for viewing angles and dark-scene smear worth testing in the return window.
- The main alternative
- Acer's own ED340CUR X0 doubles the refresh to 200 Hz on the same 34-inch curve for the step-up money.
