      Best source signal?

      Jack writes: Encouraged by your feedback on the quality of modern TVs, I recently upgraded from a Panasonic plasma to an LG G4, and it's fantastic. However, I’m concerned whether I’m receiving the best source signal. I have a Denon AVR X6300H and am connecting my cable box, Amazon Fire TV Cube, and an Oppo 203 through it. Is the receiver transmitting the highest signal available from these sources? When I access the TV's apps like YouTube and Netflix, they seem to display better quality.

      First off, congratulations on your new TV! It’s always great to hear from people who are excited about moving on from plasma TVs, which were excellent in their time and still enjoyable to watch. However, as I’ve mentioned, many modern TVs exceed plasma models in various important aspects, though not in all areas – plasma’s motion performance remains appealing, but we’ve made significant improvements in contrast and color since then.

      I’ve covered this before, but it’s worth reiterating: If you’re routing a video signal through an A/V receiver, I strongly advise disabling the receiver's video processing. This isn’t the first time I’ve heard that in-TV apps appear superior to other sources, but there are multiple reasons why signals through the receiver may not look as good.

      Access the video settings in your Denon's user menu (look for Video Mode) and choose the option for “passthrough” or “off.” This setting will relay an unaltered signal to your TV.

      Some TVs may require you to enable enhanced color for HDR on specific HDMI ports. For your LG G4, go to Settings, then General, and then HDMI Deep Color. Ensure that the HDMI port you’re using for your receiver – typically the eARC port – has HDMI Deep Color enabled. This will allow HDR signals coming through the receiver to be displayed correctly, primarily HDR content from your Fire TV Cube. Additionally, ensure your picture settings for that HDMI port match those for streaming content, as LG OLEDs require adjustments for each HDMI port separately, and HDMI picture settings are distinct from those of streaming apps and Home Screen settings. (This is one of my few persistent grievances with LG TVs; otherwise, I really appreciate them.)

      Backlight bleeding blues

      Dhruva writes: What level of backlight bleed is acceptable in an LCD panel? I recently got a 75-inch Bravia 3, prioritizing size over picture quality (moving away from OLED). Upon receiving it, I noticed significant backlight bleeding from the top right corner. I’m disappointed and want to understand what level of this issue is acceptable.

      I’m sorry to hear about your situation. No one wants to feel let down by a new TV.

      When I learned you switched from an OLED to a Bravia 3, it struck me as a significant transition, and it’s no wonder you’re noticing backlight issues. The image you sent clarifies the situation.

      (Note: If you think a photo might help in diagnosing a problem, send one; it often provides valuable context, and I appreciate seeing your A/V gear.)

      In your photo, the upper right corner of the TV looks markedly different from the others, which indicates a problem. This might stem from a quality control issue or could be a result of some impact during shipping, unboxing, or setup.

      This is not how the TV should function – something’s off. I recommend having it replaced, as all corners should exhibit similar performance.

      Set it and forget it

      RB writes: I recently bought a Hisense 75U8N 2024 model and I’m really enjoying it. Quick question: When moving from cable to streaming to Blu-ray, do I need to manually switch between SDR and HDR? Is there any downside to leaving the setting on HDR?

      This is a great question. When you activate deep color or HDR for an HDMI input, you won’t mess up SDR content being played through that HDR port. Generally, displaying SDR in an HDR format – or Rec. 709 in a DCI-P3 or BT.2020 format – is manageable for TVs. The trouble arises when you inadvertently force an HDR signal onto a TV set to SDR, resulting in a washed-out, overly colored mess. So, in essence, you’re good to go.
