Sceptre's 34-inch curved ultrawide is $199.97 at Amazon, down from a $289.97 list price, and its headline 180Hz runs over DisplayPort alone. Sceptre's own signal table caps HDMI at 100Hz at the native 3440 x 1440, so the 165Hz figure in the listing title matches no port on this model.
The panel is VA, curved at 1500R, rated for 400 cd/m2 typical brightness, a 3,000:1 contrast ratio and AMD FreeSync Premium. A 34-inch 3440 x 1440 screen under $200 is unusual enough that the distance between the spec sheet and the listing is worth settling first.
What Sceptre actually publishes about this monitor
Sceptre is a budget house brand, but it is not a silent one. The company publishes a full itemised spec sheet for the 2025 revision, down to per-port signal tables, pixel pitch and screw sizes.
What Sceptre does not do is sell it. The buy button on that page is disabled in the page's own code and reads "Find it at your E-Tailers", pointing instead at Amazon and Walmart.
The price printed beside that dead button is $499.99. Sceptre publishes a number it has no way to charge, which leaves Amazon's $289.97 list price as the only anchor attached to a working checkout.
The model code is unsettled too. Sceptre's page heading says C345B-QUT168 (2025), the page title says C345B-QUT1681, and Amazon's spec table records C345B-QUT168.A1.

Where the listing and the spec sheet disagree
The listing title claims 100% sRGB. Sceptre's spec sheet says 99%, and Amazon's own structured spec table on the same product page also records 99.
The 165Hz in that title is not a typing error so much as a leftover. It is the DisplayPort ceiling of the previous 2023 revision of this monitor, which Sceptre still lists separately at 165Hz over DisplayPort and 100Hz over HDMI.
The response time is the other hedge worth unpicking. Sceptre's product page gives only "1ms Blur Reduction" with no method, while Sceptre's manual for the same chassis states "1ms with MPRT" and documents an MPRT toggle in the on-screen menu.
MPRT describes motion clarity rather than pixel transition speed, and no grey-to-grey figure appears anywhere in Sceptre's documentation.
HDR is listed as a plain yes, with no tier and no peak brightness attached. The only certifications Sceptre names are HDMI, VESA and AMD FreeSync Premium.
The stand tilts 15 degrees back and 5 degrees forward, and that is the entire range. Sceptre's table has no row for height, swivel or pivot, and the mount is the smaller 75 x 75 mm VESA pattern rather than 100 x 100 mm.
One detail does land correctly. The box ships with a DisplayPort cable and no HDMI cable, which is the right cable for 180Hz.
How the price compares with other ultrawide deals
Nothing else in the same group of monitor deals reaches 3440 x 1440 for this money. The closest comparison is a larger, faster Samsung at well over half as much again.
| Monitor | Panel | Refresh rate | Amazon price |
|---|---|---|---|
| Sceptre C345B-QUT168 | 34-inch VA, 3440 x 1440, 1500R | 180Hz over DisplayPort | $199.97 |
| Samsung Odyssey G5 34-inch | 34-inch VA, 3440 x 1440, 1000R | 165Hz | $349.99 |
| ASUS ROG PG27UCDM | 26.5-inch QD-OLED, 3840 x 2160 | 240Hz | $1,099.00 |
The Samsung 34-inch Odyssey G5 is $349.99 at the time of writing, $150.02 more for a VA ultrawide of the same resolution at 165Hz with a tighter 1000R curve. Digital Citizen's own check a day earlier put that same Samsung listing at $249.99, so the gap between the two was half as wide on October 18.
The ASUS ROG PG27UCDM at $1,099.00 is in another category entirely, a 26.5-inch 4K QD-OLED at 240Hz with DisplayPort 2.1a and USB-C power delivery. It is in the list as a reminder of what the Sceptre is not.
For comparison at the top of the 34-inch ultrawide market, Philips uses QD-OLED and 280Hz at that size. Among budget curved panels, a 32-inch LG UltraGear at 1440p has recently sat around the same $199.99 without the extra width.
What Sceptre leaves unpublished
Sceptre lists no USB ports of any kind, no USB-C, no power delivery and no KVM switch, and its spec table has no row at all for the rear lighting the listing advertises. The FreeSync range in hertz, a grey-to-grey response figure and any DCI-P3 coverage number are missing as well.
The download section for the 2025 revision offers product photos and no manual, so the printed documentation available online still describes the older 165Hz version. Amazon showed $199.97 with Amazon.com as both seller and shipper when this listing was checked on October 19, and that price can move without notice.
