The refresh rate is NOT overclockable, despite what the product description claims. Frames are skipped on all inputs at any refresh rate higher than 60 Hz (even at 61 Hz), and frames are repeated at lower refresh rates, which causes judder.
Monoprice (left) vs. Catleap (right) at 2560x1600 @ 85 Hz:
A passive DVI splitter was used for this test to eliminate software factors. The splitter cannot handle higher pixel clocks because of the reduced signal strength, so the test was done at 2560x1600 @ 85 Hz.
The Catleap is a 2560x1440 monitor without a scaler, but it can display 2560x1600 with the bottom 160 pixels cut off. The test was done at 2560x1600 to eliminate scaling as a factor on the Monoprice monitor.
Result: The Monoprice monitor skips frames at 85 Hz, while the Catleap does not. The Monoprice is also two frames behind (~23.5 ms) in both photos.
Monoprice at 2560x1600 @ 120 Hz:
The monitor was connected directly to the video card to test 2560x1600 @ 120 Hz.
Result: The Monoprice skips every other frame at 120 Hz, effectively making it 60 Hz. This is visible on the test even without a camera.
Monoprice (left) vs. Catleap (right) at 2560x1600 @ 60 Hz:
This test was done using a passive DVI splitter at 2560x1600 @ 60 Hz to eliminate software and scaling factors.
Result: The Monoprice monitor is consistently one frame behind the Catleap at 60 Hz (~16.7 ms).
Result: The Monoprice monitor uses response time compensation (RTC) or "overdrive" to accelerate response times. The overdrive produces significant inverse ghosting against lighter backgrounds. The overdrive cannot be adjusted or disabled.
Monoprice @ 100/50/0 brightness:
Result: The backlight does not flicker at any brightness level.
- 2560x1600 @ 60 Hz is supported on all inputs including HDMI (may require pixel clock patch for older video cards).
- 1920x1080 and 1280x720 are scaled properly with "Auto" scaling.
- Only 60 Hz and 30 Hz refresh rates are supported properly.

- The scaling options affect all resolutions and inputs at once, so each input cannot be set independently.
- The ▲ button cycles through the scaling options, but switching is slow because it only responds once every 5 seconds.
|16:10||Stretches to fill the screen|
|4:3||Stretches to 4:3 with black bars on the left and right sides|
|Auto||Preserves aspect ratio|
|Overscan||Cuts off 5% from each side and stretches to fill the screen|
Downsampling is possible with limitations:
- Refresh rates near 60 Hz have artifacts, and lower refresh rates repeat frames.
- Downsampling only works properly with the "16:10" scaling option.
- The vertical total must be between 2201 and 2299 inclusive.

Brightness and Contrast
- The brightness setting is a proper backlight control that does not crush blacks.
- The brightness range is about 25-375 cd/m² in the middle of the screen at the native white point.
- Reducing the brightness causes very faint horizontal lines to appear every few lines, mostly noticeable on midtones.
- The contrast is about 933:1 at the native white point.
- The contrast setting should be set to 75 to avoid banding.
- The contrast is set to 70 by default but behaves like 75 until the contrast or color settings are changed.
|100||375 cd/m²||0.40 cd/m²|
|75||280 cd/m²||0.30 cd/m²|
|50||196 cd/m²||0.21 cd/m²|
|25||112 cd/m²||0.12 cd/m²|
|0||25 cd/m²||0.027 cd/m²|
Values are approximate due to measurement variations.
- "Normal" produces the native colors of the panel.
- Green cannot be reduced without banding, which is unfortunate because IPS panels tend to have too much green.
- The presets do not seem to be factory adjusted and are likely the same on every unit.
Color temperatures are approximate due to measurement variations.
Result: The color gamut is close to Adobe RGB and covers all of sRGB. The monitor does not have an sRGB mode, so colors are oversaturated except in color-managed programs with a proper color profile.
Native vs. D65 @ 2.2 gamma:
- These profiles can be used at any brightness.
- The contrast should be set to 75 for both profiles.
- Both profiles were calibrated using the "Normal" preset to avoid banding.
