Background : I was in search for a good but not pricey TV because of the following1. My Samsung 49" K6300 Curved TV had gone kaput in 4-5 years (DOP - Somewhere in 2017 - early 2018)2. I was dragging my old TV with ever growing shadows accompanied with visibility issues.3. K6300 was an eye pleasure when in good condition with amazing blacks and motion smoothness - beautiful out of the box colors.Since a Tier 1 brand like Samsung had betrayed the trust after paying a premium , I was in the lookout of a mid range TV with up-to-date features - my check list included the following1. Solid warranty clause with no Money extorsion policies like LG OLED post 1 year end.2. Good sound system - Preferably with a sub-woofer.3. Full content support for Netflix & Prime Videos - Dolby Vision/Atmos/HDR10+4. Solid Blacks - K6300 got me a taste of it5. IPS panel - if available6. 10 bit panel preferably with wide color gamut of 1 billion + colors7. HDMI 2.1, eARC8. Solid color optimization chip/engine9. Intended for Casual Gaming.Source (for Recommendation) - VMONE.in ( Vineet Malhotra -Can't thank him enough with words)Purchase HistoryOrder Placed - 14.7.23Inv. Dt 15.7.23Delivered - 17.7.23 by 11 AMSupplier - Dawntech ( Kolkata warehouse I suppose)Installation Dt - 17.7.23 by 4:30 PM ( After 1-2 hours of delivery , had to place a call log in Toshiba CC no mentioned on Box)Product Experience :Vida OS - Is seemingly lighter than Taizen (ref. Samsung K6300)Using TV with Airtel Xstream - 200 Mbps Unltd. connection4K HDMI Cable - Not SuppliedPic Quality - Colors out of the box need calibration/setting as per your own taste. HDMI 1 port will support Dolby Atmos & HDR , while switching to HDMI 1 from other ports - 10 bit display msg shows which is a good sign ( Review tell it otherwise - 8 bit FRC )DTH Performance - Full HD channels work like a charm with upscaling , SD channel are OK as expected. Really liked DTH HD channels like Set max, Times Now News Star Sports etc.Content Performance - Youtube- Properly coded 4k videos work flawlessly with great sound and clarity and zero lag.Netflix & Prime Vid - After personal color setting these look amazing , with magnificent blacks. Watched Indian and Hollywood series and movies. There is some amount of glare as well - used warm yellow lamp shade light for viewing in moderately lit room.Sound : Played classic 90s melodies and found the base (from Sub woofer) quite pleasing and not over powering ( Boost Effect @ 2)Over all satisfied with Panel and sound . Will further do tweaks with picture settings.Please consider this as my initial impressions.Will update as my usage will increase over weeks.Update 9.8.2023I had to finally re-calibrate the pic setting manually.Out of the box - backlight was set to max, increased sharpness etc.Just Googled the common pic setting for major brands - including Toshiba and got it corrected.Watched Netflix Doc Veerappan (Tested in White/Yellow light and dark conditions) and found the visual quite appealing- after pic settings my mode resembles Cinema mode. The TV does not have Pic/Color presets rather has HDR presets as Day Std Night Sports.Sound - I keep my windows - just behind my sofa open so amidst vehicle sound also the dialogues were clear. Thanks to surround sound and in-built woofer.Fire Stick - Happy to see email from Toshiba in my inbox for free coupon. Sad that I had purchased it along with the TV at a special price. Planning to sell it on OLX and get the free one from the Company.DTH - HD Channels Very clear with Dolby Digital Logo enabled.DD National (Classic SD)- Close up scenes also very fine, distant scenes also not badGaming - Yet to connect PS4.Sports- Watched badminton videos in 4K 50 hz - smashes @ 420 Kmph never left a trail on screen. Wimbledon 2023 Finals on 1080 - Good as the recordings were subdued fearing piracy by Disney HotstarHave run all sample 4K Dolby Vision & HDR content that youtubers swear by- got solid performance from TVSlow Vidaa OS rant from everyone is a sham. Experience it to believe it . It is faster than my Airtel Xtreme Android Box - the one that receives regular updates!Rest you can easily check display running hours from diving deep into settings.I think I am tending to increase ratings from 4 to 5 stars. Just for the REGZA Pic & Sound from Toshiba.Good and durable Japanese brands Like Sanyo, Toshiba, Panasonic ( that bring in proprietary tech) should be endorsed (even thought they may be manufactured locally under strategic partnerships) by the Indians else everything is gonna be PRC/Korea Inspired.
