TCL have been in the display space for a while making TV’s, but the company is now planning to launch two desktop monitors, one in 27″ and the other in 34″ ultrawide sizes. Both feature high-end Mini LED backlights with a large number of local dimming zones and are aimed at “professional HDR” uses. We will run through the specs and details of their two new screens below, along with some…interesting claims they are making in their marketing material.

TCL 34R83Q

First up is a 34″ ultrawide model featuring a “Fast-HVA” panel from CSOT which has a 1500R curvature. It has a 3440 x 1440 resolution, 1ms G2G response time, 4000:1 contrast ratio, 178/178 viewing angles, 8-bit+FRC colour depth and a wide colour gamut covering 97% DCI-P3 and 95% Adobe RGB (along with 99% sRGB). The screen also comes factory calibrated with a dE < 2 and is also ‘Pantone Validated’ for accuracy.

Gaming performance

This model has a 170Hz refresh rate as well, and is supported by adaptive-sync for variable refresh rates from compatible NVIDIA and AMD systems. It is expected to be certified under the AMD ‘FreeSync Premium’ and NVIDIA ‘G-Sync Compatible’ schemes.

In terms of the ‘Fast-HVA’ panel they are using here, this seems to be a VA-type panel and will hopefully offer decent response times like those featured in some of Samsung’s screens which also use panels from CSOT nowadays.

A dubious claim on the TCL website says “TCL CSOT Fast-HVA is the screen technology of the world’s high-end e-sports monitors” – we’re not sure which e-sports monitors they’re referring to there, but that doesn’t feel like a true or realistic claim. Actually a lot of e-sports monitors are still TN Film based, and certainly offer higher refresh rates than the 170Hz used here (e.g. the Asus ROG Swift Pro PG248QP)

HDR capabilities and QD-Mini LED Backlight

In terms of its HDR capabilities, the screen has a 1,152 zone Mini LED backlight which offers a high level of local dimming. TCL actually refer to this as a “QD-Mini LED” backlight, and their website goes on to state:

TCL’s QD-Mini LED, combined the merits of QLED and OLED technologies, transforming the traditional backlight into to pixel-level precision lighting. It also uses the world’s leading QLED technology, offering contrast and color gamut on par with OLED, yet it has a higher peak brightness and a longer lifespan. This is the future technology of display.

TCL website

This seems an unusual claim as on the one hand the screen has 4.95 million pixels, and on the other hand they are talking about a 1152 zone backlight. For now we would remain cautious of these marketing claims, as well as talk about “QLED” which basically just means a Quantum Dot coating has been used to offer the wider colour gamut.

Aside from these claims, there is a peak brightness spec of 1600 nits listed, and the screen therefore also conforms to the VESA DisplayHDR 1400 tier.

Connectivity and Features

For connectivity there are 1x DisplayPort 1.4 and 2x HDMI 2.1 available (capabilities not listed). A USB type-C connection is also included with DP Alt mode and 90W power delivery. There’s also 2x USB data ports and a headphone jack provided. A KVM switch function is supported along with PiP and PbP modes. The stand offers tilt, height and swivel adjustments. The screen also includes 2x 3W integrated speakers and there’s some RGB lighting “wings” on the back of the screen too.

TCL 27R83U

Also being released is a 27″ model. This carries a lot of similar specs and features as the 34″ model above. It has a 3840 x 2160 “4K” resolution ‘Fast-HVA’ panel from CSOT again, but is a flat format on this model. There’s also a 1ms G2G response time, 4000:1 contrast ratio, 178/178 viewing angles, 8-bit+FRC colour depth and a wide colour gamut covering 97% DCI-P3 and 95% Adobe RGB (along with 99% sRGB). The screen also comes factory calibrated with a dE < 2 and is also ‘Pantone Validated’ for accuracy.

This model has a 160Hz refresh rate with adaptive-sync support for VRR. It’s also got a 1152-zone QD-Mini LED backlight with a 1600 nits peak brightness and certification under the VESA DisplayHDR 1400 tier. The same dubious claims are made about the dimming control as we discussed above.

Connectivity and Features

The connectivity and related features are the same as the 34″ model with 1x DisplayPort 1.4 and 2x HDMI 2.1 available (capabilities not listed). A USB type-C connection is also included with DP Alt mode and 90W power delivery. There’s also 2x USB data ports and a headphone jack provided. A KVM switch function is supported along with PiP and PbP modes. The stand offers tilt, height and swivel adjustments. The screen also includes 2x 3W integrated speakers and there’s some RGB lighting “wings” on the back of the screen too.

Pricing and Availability

There doesn’t seem to be much firm information about this yet for either model, but we will update the news piece when we have any more information. The 34″ model is popping up on a few European retailers already price at ~€1100 Euro.
