No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I would check two things:

  1. Is it a QLED tv? Those are very efficient with the backlight power. QLED only have a blue led backlight and the "quantum dots" in the panel between the backlight and the LCD panel absorb the blue light and emit the red green and blue needed to create the full color spectrum.

  2. How many nits of brightness does it produce? I'd check for the specific model on RTINGS. It won't help OP much if the TV is efficient, but so dim that it's unusable in their case.

Reflectivity also helps with brightness when viewed in a bright room. The less reflective (matte) the less brightness the TV needs to overcome distracting light sources reflecting on the screen.

Edit: Had to look it up to be sure, normal LED panels use filters that filter red, green, and blue light from a white light source. This means roughly 1/3 of the light from the backlight is filtered away, hence the energy inefficiency vs QLED which uses the energy from the blue light to create the colors.

Intestingly, some DLP projectors use alternating red, green, and blue light sources which strobe on the DLP chip which takes turns modulating the intensity of each color. Less efficient (and bright) DLPs use a single white light source and a color wheel (rotating color filter).
