Hisense H6510G TV Review

The Hisense H6510G has a decent design and looks almost identical to 2019's Hisense H6570F. It has thicker borders than the Hisense H6570G and the back looks different. Overall, there's nothing premium about its design as it's made with basic plastic, and the metal on the back feels cheap.

The stand consists of two plastic feet that hold the TV fairly well, but there's still some wobble. The stand is almost as wide as the TV itself, so you need a big table to place it on. The feet can't be moved inwards to accommodate for smaller tables.

Footprint of the 55" TV: 39.9" x 8.9".

The Hisense H6510G has the same pattern on the back as the Hisense H6570F. It's mainly metal except for the part where the inputs are, which is made out of plastic. Sadly, there's no cable management.

This TV has thicker borders than the Hisense H6570G, which may be a bit distracting.

The panel itself is thin, but the TV may stick out a bit when wall-mounted due to the thicker bottom portion.

The Hisense H6510G has an okay build quality. The plastic and metal materials feel cheap. The bezels are a bit loose and you can easily move them. The stand supports the TV well, but it doesn't remove wobble completely. Lastly, the screen torques a bit, which is something we also noticed with the Hisense H6570G.

The Hisense H6510G has an outstanding contrast ratio, which is expected from a VA panel, and it may vary between units. It delivers deep blacks when viewed in the dark. We received reports that the 75 and 85 inch models have local dimming that would improve the contrast, but we don't know for sure.

The Hisense H6510G has disappointing peak brightness, similar to the Hisense H6570G. Its brightness remains consistent across varied content, but it doesn't get bright enough to combat glare. If you want a significantly brighter TV, check out the Hisense R6090G.

We measured SDR peak brightness in the 'Theater Night' Picture Mode after calibration. If you want a brighter image and don't mind losing image accuracy, we achieved 286 cd/m² in the 10% window in the 'Game' Picture Mode with Active Contrast set to 'High'.

The Hisense H6510G Series doesn't have a local dimming feature. The video above is provided for reference only. We received reports that the 75 and 85 inch models have local dimming, but we don't know for sure.

This TV has poor HDR peak brightness. It only gets a bit brighter than in SDR, and it's not enough to make highlights pop the way the creator intended.

We measured peak brightness in the 'HDR Theater' Picture Mode with everything else at their default settings. We reached 285 cd/m² in the 25% window with the 'HDR Standard' Picture Mode, but this results in a less accurate image.

The gray uniformity isn't bad, but this may vary between units. The edges of the screen are darker and there's dirty screen effect in the center. Uniformity is actually worse in dark scenes as there's backlight bleed at the edges.

The black uniformity is incredible, but this may vary between units. There's backlight bleed along the edges, but it's not too noticeable, and there's not much blooming around the center cross. We received reports that the 75 and 85 inch models have local dimming, improving black uniformity, but we don't know for sure.

This TV has narrow viewing angles and isn't suggested for a wide seating arrangement. You quickly lose image accuracy when viewing off-center. If you want a budget-friendly TV with wide viewing angles, check out the LG UN6970.

The Hisense H6510G has decent reflection handling, exactly like the Hisense H6570G. It performs best in dim to moderately-lit rooms but struggles if there's direct sunlight on it.

The out-of-the-box color accuracy is bad, but this may vary between units. White balance is way off and most colors are slightly inaccurate. Gamma doesn't follow the target curve very well and most scenes are brighter than they should be. Color temperature is also much warmer than our 6500K target.

We normally measure accuracy using our recommended picture settings that we keep the same across one brand. In this case, we use the 'Low' Color Temperature on all our Hisense TVs, but on this one, it results in a very warm temperature. Setting it to 'Medium' results in a color temperature of 6612K, which is much closer to our 6500K target. It also significantly improved the white balance dE to 2.78, color dE to 2.41, and gamma stayed about the same.

The color accuracy after calibration is excellent, but it was difficult to calibrate and it's not as good as some other TVs we've tested. However, your experience may vary. There are still some slight inaccuracies with colors and white balance, but most people shouldn't notice them. Gamma does a much better job at following the target, and color temperature is almost spot on with our target.

You can see our recommended settings here.

This TV displays 480p content, such as from DVDs, without any issues.

The Hisense H6510G displays 720p content, such as from cable boxes, without any issues.

1080p content, such as from Blu-ray players, looks almost as good as native 4k content.

Unlike the Hisense H6570G, the Hisense H6510G displays native 4k content perfectly and there aren't any artifacts.

This is a 4k TV that can't display 8k content.

This TV uses a BGR subpixel layout, which may affect the way text is rendered when using it as a PC. Read about it here.

Like the Hisense H6570G, the Hisense H6510G has an okay color gamut, but it isn't considered a wide color gamut for HDR content. It has good coverage of the commonly-used DCI P3 color space, but very limited coverage of the wider Rec. 2020. The EOTF follows the target curve well, except some scenes are over-brightened. The image is a bit brighter in 'Game' mode, as you can see in this EOTF.

If you find HDR too dim, set Gamma to '1.8' and Active Contrast to 'High'. This results in a noticeably brighter image, as seen in this EOTF.

We received reports that the 75 and 85 inch models display a wide color gamut for HDR content, but we don't know for sure.

The color volume is mediocre. It displays dark, saturated colors well thanks to its outstanding contrast. However, it's limited by the lack of a wide color gamut and by its low peak brightness. We received reports that the 75 and 85 inch models display a wide color gamut, which could improve the color volume, but we don't know for sure.

The Hisense H6510G has excellent gradient handling, and it's much better than the Hisense H6570G. The most visible banding is with grays and greens, and there's some minor banding in red and blue. There's a Noise Reduction setting, but it doesn't do anything to improve the gradients.

There are no signs of temporary image retention, but this may vary between units.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

This TV has okay response time, but motion doesn't look clear and there's motion blur with fast-moving objects. You may also notice image duplication due to the backlight's 180Hz flicker.

This TV uses Pulse-Width Modulation (PWM) to dim its backlight. It flickers at 180Hz at any backlight setting below 100, which may cause image duplication.

The Hisense H6510G doesn't have a Black Frame Insertion feature. The backlight flickers at 180Hz at all backlight levels below 100.

Update 01/12/2022: We set the Motion Interpolation (60 fps) result to 'No' because it was incorrectly listed as 'N/A'.

This TV doesn't have a motion interpolation feature.

Despite having a slow response time, there's still some stutter with lower-frame rate content.

The Hisense H6510G automatically removes judder from native 24p sources, such as from Blu-ray players or native apps. There's no setting needed to remove it.

This TV doesn't support any variable refresh rate technology.

This TV has fairly low input lag, but it's not good enough for competitive gaming. It's about the same as the Hisense H6570G, except the input lag at 1440p is significantly higher. We had to measure the 1440p input lag with our laptop, instead of the PC we normally use for these tests because our PC couldn't force the 1440p resolution properly. You need to be in 'Game' mode to get the lowest input lag possible. If you want something with much better input lag, then check out the TCL 4 Series/S434 Android 2020.

The Hisense H6510G displays most common resolutions at 60Hz, which is great. It displays proper chroma 4:4:4, which is important for text clarity. You need to be in 'Game' mode for it to display 4:4:4. Also, it accepts a 1080p @ 120Hz signal but skips frames. To achieve full bandwidth, enabled HDMI 2.0 Enhanced Format.

This TV can pass both DTS and Dolby Digital via ARC or optical, which is great, but it doesn't support eARC. For ARC to work, simply set Audio Output to 'Passthrough'.

The Hisense H6510G has a poor frequency response. It has a fairly well-balanced sound profile, which is good for dialogue, and it gets loud. However, it doesn't produce much bass.

The distortion performance is decent. There's hardly any distortion at moderate listening levels, but it gets more noticeable at its max volume. However, it depends on the content, and not everyone may hear it.

The Hisense H6510G Series uses Android TV. It's somewhat easy-to-use, but menu navigation can feel laggy. At times during testing, apps would become unresponsive until we restarted the TV.

There are ads on the home screen, but we couldn't get a picture of them. You can see the ads on the Hisense H6570G here.

This TV offers you access to the Android TV Google Play Store with a large number of apps, which should cover your needs.

This TV comes with the same remote found on other new Hisense TVs. It has quick-access buttons to popular streaming services and a built-in mic for voice control through Google Assistant. You can ask most basic commands through voice control, such as searching for content, but you can't ask it to change some settings.

There's a button underneath the TV that allows you to power it On/Off and change inputs.
